  • All modules ship with the same device name “PNIO”. The name must be unique in your network – assign it to each module individually.
  • The MAC address is on the nameplate. When assigning, you compare it with the list of accessible devices.

Assign device name (TIA Portal)

  1. In the network view, right-click the connection between PLC and module and select Assign device name.
  2. Select PN/IE as the type of PG/PC interface, select your network card, click Update list.
  3. Select the module by the MAC address on the nameplate and click Assign name. The status must show “OK”.
  4. Download the configuration to the PLC and switch the module off and on once.

Which GSDML file?

The ZIP “Solidot_PN4_GSDML_V2.3” under Downloads contains one file per model. In TIA Portal you install it via Options → Manage general station description files (GSD). You then find the module in the hardware catalog under Other field devices → PROFINET IO → I/O → SOLIDOT PROFINET I/O.

First steps with the Solidot PN4

The PN4 brings inputs and outputs straight onto PROFINET: two ports with a built-in switch, spring-cage terminals, integration via a GSDML file. This guide applies to all PN4 models in the Shop – digital with 16 or 32 channels, relay, and analog with four or eight channels. It takes you from the DIN rail to the first signal in TIA Portal: power supply, wiring, installing the GSDML, assigning the device name, downloading and testing.

Before connecting

  • Mount and remove only with the power off (manual chap. 5).

  • The module has protection class IP20 and belongs in a control cabinet or an enclosure.

  • Set up the system supply (module electronics) and the field supply (inputs and outputs) separately and do not mix them.

  • Ground PE at the supply terminal securely.

  • Relay modules: only DC voltage up to 48 V at the contacts (note in the connection diagram).

  1. 1Mount on the DIN railRequired

    The module measures 25 × 102 × 72 mm (W × H × D) and snaps onto a 35 mm DIN rail. It must sit vertically so that air can flow through the housing.

    Operating temperature −10 to +60 °C. Minimum clearances and connector dimensions are in the “Dimensions & mounting” tab.

    Mounting

    1. Pull the latch at the bottom of the module outwards until it audibly clicks into place.

    2. Hook the module onto the top of the DIN rail and swing it onto the rail.

    3. Push the latch towards the rail until it clicks.

    4. Removal: insert a flat-blade screwdriver into the latch, lever it towards the module and swing the module off.

    Source: Manual chap. 3.1, 5

  2. 2Connect system and field supplyRequired

    The system supply powers the electronics: 24 V DC (18–36 V) to the three-pole terminal on the top, assigned 24V, 0V and PE.

    The field supply powers the inputs and outputs via 24V/0V in the terminal block (terminal 9/10 and 19/20, each pair connected internally). Modules with two blocks need it on both blocks.

    Relay modules (PN4-0012J, PN4-1612J): the relay block gets 24 V at terminal 10 and 0 V at terminal 20. You supply the loads via COM0–COM2 from a separate load supply.

    The manual does not state the current consumption of the electronics or the permissible current per field terminal; the cross-sections in the wiring diagram are derived.

    After switching on, PWR lights up green.

    Source: Manual chap. 3.1, 3.2, 6.1, 6.2, connection diagrams chap. 6.3

  3. 3Wire inputs and outputsRequired

    Strip 10 mm of insulation; use a wire ferrule (10 mm) for fine-stranded wires. Press the button above the terminal with a flat-blade screwdriver up to 3 mm wide and insert the wire.

    Digital inputs of the B models are PNP, filter fixed at 3 ms. On the PN4-1612J the inputs are NPN/PNP compatible: COM to 0 V for PNP sensors, to +24 V for NPN sensors.

    Transistor outputs switch +24 V, max. 500 mA. Relay outputs switch up to 2 A in three groups of four contacts each (COM0: Y00–Y03, COM1: Y04–Y07, COM2: Y08–Y0B).

    Analog channels: signal to AI or AO (terminal 1–8), reference to COM (terminal 11–18), twisted and shielded.

  4. 4Install the GSDML fileRequired

    TIA Portal only knows the PN4 once its device description is installed. The ZIP “Solidot_PN4_GSDML_V2.3” under Downloads contains one file per model. Which one belongs to your model is shown in the PROFINET tab.

    Install

    1. Unzip the ZIP file.

    2. In TIA Portal, open Options → Manage general station description files (GSD).

    3. Select the unzipped folder as the source path.

    4. Select the file with the status “Not installed” and click Install. If it is already installed, close with Cancel.

    Source: Manual chap. 7.2.1, step 5

  5. 5Add the module in TIA PortalRequired

    The manual shows the integration with a Siemens S7-1200 and TIA Portal V17. The PC must be in the same network as the PLC.

    Hardware configuration

    1. Create a project and insert your PLC under Add new device.

    2. Under Online access, click Update accessible devices – the module appears there with its name “PNIO”.

    3. In Devices & networks, open Other field devices → PROFINET IO → I/O → SOLIDOT PROFINET I/O in the hardware catalog and drag your model into the network view.

    4. Click “Not assigned” on the module and select the PROFINET interface of the PLC.

    Show wiring “PROFINET to the controller”

    Source: Manual chap. 7.2.1, steps 2–6

  6. 6Assign device nameRequired

    PROFINET finds devices by their name; the PLC then assigns the IP address. Out of the box, every PN4 is called “PNIO” – each module needs its own name that matches the name in the project.

    Assign name

    1. In the network view, right-click the line between PLC and module and select Assign device name.

    2. Select PN/IE as the type of PG/PC interface, select your network card, click Update list.

    3. Select the module by the MAC address on the nameplate and click Assign name.

    4. Check that the status shows “OK”, then close.

    Several modules: assign them one after the other, each by its MAC address. Duplicate names in the network cause errors.

    Source: Manual chap. 7.2.1, step 7; GSDML (device name “PNIO”)

  7. 7Download and testRequired

    After downloading the configuration, switch the module off and on once. If all symbols in the online view are green, the connection is running.

    TIA Portal assigns the channel addresses; you find them in the Device overview of the module. In the PROFINET tab you use this start address to work them out for each terminal.

    Check inputs and outputs

    1. Select the PLC, Download to device, “Stop all”, Load, Finish.

    2. Switch the module off and on, then Go online.

    3. Inputs: create a watch table, enter e.g. %IB1, click Monitor all.

    4. Outputs: in the force table, force e.g. %QB1 with value FF – all eight channels of the byte switch. Bit 2 alone (channel 2) corresponds to 00000100.

    Afterwards, cancel forcing and stop the PLC, otherwise the next download fails (manual chap. 7.2.1 and 8.3).

    The manual gives the value 0x03 for channel 2 alone; correct is 00000100 = 0x04 (calculated).

  8. 8Set module propertiesOptional

    Double-click the module to open its properties. After every change, switch the module off and on again.

    Data Clear or Hold Settings (modules with outputs): the factory default is 0 = Clear – on loss of connection the module switches the outputs off. With 1 = Hold they keep their state.

    Analog modules: measuring range per channel (Channel Range Select, factory default code 0) and, for inputs, an averaging filter per channel from 1 to 1024 ms (factory default 10 ms).

    Summary

    1. In the System Block, select the CPU and set the IP address and station name of the CPU under Communication.

    2. Import the GSDML file under File → GSDML Management.

    3. Open Tools → PROFINET, set the CPU as PROFINET controller and add the PN4 modules. The device name must match the module name, the IP address must be in the network of the PLC.

    4. Generate, download, switch the module off and on again and monitor or force the channels in the status chart.

  10. 10More modules in a lineOptional

    Thanks to the built-in switch, you connect several PN4 without an external switch: P2 of one module to P1 of the next. Max. 100 m per segment, shielded cable category 5 or higher.

    Each module in the line needs its own device name.

    If a module has no power, you can no longer reach the modules behind it (derived from the built-in switch; the manual does not mention a bypass).

Mounting step by step

  1. 1Choose the installation site

    Protection class IP20: the module belongs in a control cabinet or an enclosure. The cabinet needs good ventilation, e.g. a fan.

    Mount the module vertically so that air flows through the housing. Do not mount it next to or above devices that give off a lot of heat. Operating temperature −10 to +60 °C, humidity up to 95 %, non-condensing.

    At least 10 mm to neighbouring modules, 45 mm upwards and 25 mm downwards to devices or cable ducts. This leaves room at the top for the supply connector and patch cables.

    Show clearances in the drawing

  2. 2Mounting and removing

    Mount and remove only with the power off.

    • Pull the latch at the bottom of the module outwards until it clicks into place.

    • Hook the module onto the top of the DIN rail and swing it onto the rail.

    • Push the latch towards the rail until it clicks.

    • Removing: insert a flat-blade screwdriver into the latch, lever it towards the module and swing the module off.

    Show wiring “System supply 24 V”

  3. 3Connecting the wires

    Strip 10 mm of the wire. Stranded wires get a wire ferrule with a 10 mm sleeve length; solid wires go in directly.

    Press down the push button above the terminal with a flat-blade screwdriver (up to 3 mm), insert the wire, release, give the wire a short pull.

    Signal terminals take 0.3–1.0 mm², the supply terminal 0.3–1.5 mm². Run the supply cable twisted, use shielded pairs for analog signals.

Solidot PN4 remote I/O

Solidot Profinet remote I/O module PN4 with 16 digital channels
Solidot Profinet remote I/O module PN4 with 16 digital channels
You need a handful of signals somewhere in the plant where there is no PLC — and you do not want to build a bus coupler, a power supply and half a cabinet around them. That is what the PN4 is for: electronics, PROFINET port and terminals sit in one housing 25 mm wide. Wire it up, load the GSDML into your project, done. 🏭 Typical applications Distributed signals along conveyors: collect limit switches, photoelectric sensors and valves at the conveyor section instead of running twenty wires back to the main cabinet. Expanding an existing S7: when the slots on the central rack are full, you simply hang the PN4 on the existing PROFINET network. Machine retrofit: the existing controller stays, the peripherals move to PROFINET — without replanning the wiring inside the machine. 🔌 Versions with 16 channels PN4-1600B: 16 digital inputs, PNP, 24 V DC, 4 mA input current, 3 ms filter time PN4-0016B: 16 digital outputs, PNP, max. 500 mA per channel, with overvoltage and overcurrent protection PN4-0808B: 8 inputs and 8 outputs in the same housing All channels are optically isolated (500 V AC) and rated for resistive and inductive loads. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The PN4 registers as an ordinary PROFINET device. Tested and in use with Siemens S7-1200 and S7-1500 (TIA Portal), it works just as well with CODESYS controllers, Beckhoff TwinCAT and any other master that can read a GSDML. No vendor software, no licence. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail. The terminal blocks are pluggable — you wire them up in the cabinet and plug them on afterwards. To swap a module in the field you pull the block, take the device out and plug the block back on: not a single wire is disconnected. The GSDML file, EPLAN macros and 2D and 3D models are in the downloads section of this page. 🏷️ Manufacturer and availability Solidot (Nanjing Solidot Electronic Technology) has been building remote I/O and fieldbus components for industrial series use for years. spstiger is the importer and the party responsible for CE conformity of the PN4 series in the EU — technical questions are answered by us directly, without a detour via the manufacturer.

Solidot Profinet remote I/O module PN4 with 32 digital channels
Solidot Profinet remote I/O module PN4 with 32 digital channels
32 signals on 25 mm of rail width — that is why the PN4 ends up in tight cabinets. You save the bus coupler, a separate power supply and the marshalling terminals: electronics, PROFINET port and pluggable terminals sit in one housing. Wire it up, load the GSDML, done. 🏭 Typical applications Compact sub-distribution: where a slice I/O system with coupler and end cap no longer fits, the PN4 still goes on the rail. Collection point for sensors: gather 32 limit or proximity switches at one station and send them back over two PROFINET wires. Expanding existing plants: slots on the central rack full? The PN4 joins the existing PROFINET network without touching the controller. 🔌 Versions with 32 channels PN4-3200B: 32 digital inputs, PNP PN4-0032B: 32 digital outputs, PNP, max. 500 mA per channel PN4-1616B: 16 inputs, 16 outputs PN4-2408B: 24 inputs, 8 outputs PN4-0824B: 8 inputs, 24 outputs Inputs 24 V DC PNP with 4 mA input current and 3 ms filter time, outputs with overvoltage and overcurrent protection.

Solidot Profinet remote I/O module PN4 with 4 analog channels
Solidot Profinet remote I/O module PN4 with 4 analog channels
Acquire or output analog values where they occur — without long measuring cables that pick up every disturbance on the way to the cabinet. The PN4 analog module takes 25 mm of rail width right at the machine and connects to your controller over PROFINET. No bus coupler and no separate power supply required. 🏭 Typical applications Pressure, level and temperature transmitters: read 4–20 mA sensors close to the process instead of routing the current loop across the shop floor. Setpoints for variable frequency drives: output 0–10 V or 4–20 mA directly at the drive. Proportional valves and actuators: provide analog manipulated variables in the field. 🔌 Versions with 4 channels PN4-A40V: 4 voltage inputs, selectable -10 – +10 V, 0 – +10 V, -5 – +5 V, 1 – 5 V, input impedance ≥ 2 kΩ PN4-A40I: 4 current inputs, selectable 0 – 20 mA or 4 – 20 mA, input impedance 100 Ω PN4-A04V: 4 voltage outputs, load impedance ≥ 2 kΩ PN4-A04I: 4 current outputs, load impedance ≤ 200 Ω 16 bit resolution, ±0.1 % accuracy, sampling rate ≤ 1 ksps. The measuring range is parameterised per channel in the PROFINET project, not set by jumpers on the device. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The code value ranges match the common PLC formats: 0 – 27648 and -27648 – +27648 correspond to the Siemens format, and the full 16 bit scaling (0 – 65535) is available as an alternative. Blocks from existing S7 projects therefore carry over without rescaling. The module is integrated via its GSDML — with Siemens S7-1200 and S7-1500, CODESYS, Beckhoff TwinCAT and any other PROFINET master. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail.

Solidot Profinet remote I/O module PN4 with 8 analog channels
Solidot Profinet remote I/O module PN4 with 8 analog channels
Eight analog channels on 25 mm of rail width, right at the machine instead of in the main cabinet. That saves you long measuring cables and the bus coupler along with them — electronics, PROFINET port and pluggable terminals sit in one housing. 🏭 Typical applications Measuring points on process plants: read eight pressure or level transmitters at one station without running eight current loops back. Multi-axis setpoints: supply several variable frequency drives or proportional valves from a single module. Test benches and pilot rigs: many analog channels in a small space, without a rack. 🔌 Versions with 8 channels PN4-A80V: 8 voltage inputs, selectable -10 – +10 V, 0 – +10 V, -5 – +5 V, 1 – 5 V, input impedance ≥ 2 kΩ PN4-A80I: 8 current inputs, selectable 0 – 20 mA or 4 – 20 mA, input impedance 100 Ω PN4-A08V: 8 voltage outputs, load impedance ≥ 2 kΩ PN4-A08I: 8 current outputs, load impedance ≤ 200 Ω 16 bit resolution, ±0.1 % accuracy, sampling rate ≤ 1 ksps.

Solidot Profinet remote I/O module PN4 with 12 relay outputs
Solidot Profinet remote I/O module PN4 with 12 relay outputs
When you need to switch loads a transistor output cannot handle — contactors, solenoid valves, indicator lamps, circuits on a different potential — you need relays. The PN4 relay module brings twelve of them, connects straight to PROFINET and does without a bus coupler and without a row of interposing relays. 🏭 Typical applications Contactor control: switch motor contactors straight from the controller, with no interposing relay in between. Separate voltage circuits: potential-free contacts for circuits that are not on the controller's 24 V potential. Retrofitting older plants: keep the existing relay wiring and move only the control side to PROFINET. 🔌 Versions PN4-0012J: 12 relay outputs, 2 A per channel, for resistive and inductive loads, 4 channels per common terminal PN4-1612J: adds 16 digital inputs, wired as NPN or PNP The relay outputs are doubly isolated via optocouplers and relays, withstand voltage 500 V AC. Every channel has a green LED right at the terminal. ⚙️ Core specifications Bus: PROFINET, 2 x RJ45 (100 Mbit/s), up to 100 m per segment, CAT5 Power supply: 24 V DC (18 – 36 V), galvanic isolation 500 V AC Environment: -10 °C to +60 °C operating, -20 °C to +75 °C storage, 95 % relative humidity without condensation, IP20 Form factor: 102 x 72 x 25 mm, 130 g, 35 mm DIN rail, pluggable spring-loaded terminals Diagnostics: a green LED next to every channel, plus PWR, RDY, SF and BF on the housing 🔗 Compatibility The PN4 registers as an ordinary PROFINET device. In use with Siemens S7-1200 and S7-1500 (TIA Portal), and equally with CODESYS controllers, Beckhoff TwinCAT and any master that can read a GSDML. On the PN4-1612J you decide between NPN and PNP by wiring — so you are not tied to one sensor family. 🔧 Mounting and commissioning The module clips onto a 35 mm DIN rail. The terminal blocks are pluggable — you wire them up in the cabinet and plug them on afterwards. To swap a module in the field you pull the block, take the device out and plug the block back on: not a single wire is disconnected.

Solidot Patchkabel RJ45/RJ45 – geschirmt, grün
Solidot Patchkabel RJ45/RJ45 – geschirmt, grün
Assembled, shielded Ethernet cables for the fieldbus wiring of Solidot remote I/O modules — RJ45 on both ends, green jacket per industry convention. Available in seven lengths from 0.5 to 20 m and two jacket materials. 🔌 What for Connection between PLC and remote I/O module, and for daisy-chaining module to module (2 × RJ45 per module, no switch required). Protocol-neutral: PROFINET (PN4, PN5R, PN7A), EtherCAT (EC4, EC5R, EC7A), EtherNet/IP (EI4) and Modbus TCP (MT4). 🧵 PVC or PUR — which one PVC: the more economical choice for fixed installation in the cabinet and in cable ducts. PUR: tougher, more abrasion-resistant and oil-resistant — for moving installation, machine environments and anything that does not just sit in the cabinet. 📐 Technical basis CAT 5e, shielded, 100 Mbps — matching the Ethernet interface of the Solidot modules. Maximum cable length between two stations: 100 m (fieldbus specification). Lengths: 0.5 · 1 · 2 · 3 · 5 · 10 · 20 m. Custom lengths are available from the manufacturer on request — get in touch if you need one. ⚠️ Limits stated honestly RJ45 is an IP20 connector — for control cabinets and protected enclosures. In the field with splash water or dust, M12 cables (D-coded) are the right choice. CAT 5e, not CAT 6/CAT 6a. Not meant for gigabit backbones — the Solidot modules operate at 100 Mbps anyway.
