Where the variables are

With hardware detection, TIA Portal places each plugged-in module in slot 1, 2, 3 … and assigns the addresses. The table counts on from your start address, the way TIA assigns them when nothing before is occupied. The Device overview in TIA Portal is authoritative.

Factory default: voltage 0–10 V and current 4–20 mA, each as 0–27648.

First steps with the Solidot XB6S

The XB6S is a slice I/O system: a bus coupler for your network and up to 32 narrow I/O modules to its right. The hardware is the same for all four couplers; only the integration into the controller depends on the bus. Choose your coupler – then you only see the steps that apply to you.

Before connecting

  • Mount, wire and set the rotary switches only with the power off (manual chap. 4.1).

  • Degree of protection IP20: the station belongs in a control cabinet.

  • Route the system supply (coupler, P2000) and the field supply (terminals on the modules) separately and do not mix them; ground securely (manual chap. 5.2).

  • Copper wires only, rated for 80 °C.

Which bus coupler do you have?

  1. 1Plan the station: modules, order, bus currentRequired

    The coupler sits on the left, with the I/O modules to its right in any order – up to 32 modules. The end cover goes on the far right (required).

    Coupler and modules communicate via the backplane bus. For this, the coupler supplies 5 V with at most 2 A. If the modules need more, insert a power feed module XB6S-P2000 in between: it supplies the modules to its right with another 2 A.

    Put your station together in the wiring diagram. The current budget per section appears below the module chain, and the Fieldbus tab then lists all variables.

    Bus current of selected modules (5 V)

    ModuleBus current
    XB6S-1600 / 320080 / 100 mA
    XB6S-0016B / 0032B / 1616B90 / 110 / 100 mA
    XB6S-0012J/6100 mA
    XB6S-A80V260 mA
    XB6S-A80VD / A80ID210 mA
    XB6S-A80100 mA
    XB6S-A08V / A08I / A08100 mA

    The 2 A limit per section is derived from the device data; the manual does not state a rule. From 90 % load, the OVR LED on the coupler or P2000 lights up.

    Source: Manual chap. 1.3, 3.1.3, 3.4

  2. 2Mount on the DIN railRequired

    35 mm DIN rail, station mounted vertically with at least 50 mm clearance above and below the modules.

    From left to right: coupler, modules (with a P2000 in between where needed), end cover. Snap each part on individually (click) and slide it sideways against the previous one until the fronts are flush.

    Finally, fit an end stop to the left of the coupler and one to the right of the end cover and screw them tight.

    Removal: loosen the end stops, release the latches at the top and bottom with a flat-blade screwdriver, pull the module off towards the front (manual chap. 4.3).

    Source: Manual chap. 4

  3. 3Connect the supplyRequired

    System supply: 24 V DC to 24V, 0V and earth on the coupler (3-pin, spring-clamp terminal), and likewise to each P2000.

    Field supply: output modules, relay modules and analog outputs get 24 V at their own terminals (row 8/9 at the bottom). Input modules do not need one – there you connect COM to 0 V (PNP) or +24 V (NPN).

    Route the system and field supply separately, even if both come from the same power supply unit.

    Source: Manual chap. 3.1.4, 3.2.4, 5.2

  4. 4Wire inputs and outputsRequired

    All signal terminals are spring-clamp terminals (push-in) for 0.3–1.0 mm². Strip 10 mm of insulation; for fine-stranded wires, use a wire ferrule or press the release button. To release a wire, use a flat-blade screwdriver up to 3 mm wide.

    Digital inputs: one logic per module – PNP with COM to 0 V, NPN with COM to +24 V. Digital outputs switch +24 V (PNP), up to 0.5 A per channel.

    Use shielded twisted-pair cable for analog signals; shield to SHIELD. On the switchable A40/A80 you need a jumper AIx1–COM for current.

    Source: Manual chap. 3.2.4, 3.3.7, 5.2

  5. 5Switch on and check the LEDsRequired

    After switching on, PWR lights up on the coupler. OVR must stay off, otherwise the backplane bus is overloaded.

    As long as the controller is not yet exchanging data, IOR flashes at 1 Hz and SYS on the modules flashes at 1 Hz. That is correct – continue with your bus.

    LEDMeaning
    PWR onSupply OK
    OVR onBackplane bus ≥ 90 % loaded: insert a P2000
    IOR 1 Hzwaiting for the controller
    IOR onProcess data exchange running
    IOE onBackplane bus fault (module, connector)

    Source: Manual chap. 3.1.2, 3.2.2

  6. 6PROFINET: install the GSDML and detect the stationPROFINETRequired

    In TIA Portal

    1. Unzip the GSDML ZIP from the XB6S-PN2002 product page (“Downloads” tab). Options → Manage general station description files (GSD), select the folder, install GSDML-V2.43-sDot-XB6S-PN2002.

    2. In the device view, select the controller, Online → Hardware detection → PROFINET devices from network, select the interface, start the search.

    3. Tick the coupler and click Add device: TIA adopts all plugged-in modules into slot 1, 2, 3 … in the correct order.

    4. In the network view, click “Not assigned” on the coupler and select the PROFINET interface of the controller.

    The P2000 power feed module does not appear in TIA: it has no process data.

    Source: PN manual chap. 6.5.1

  7. 7PROFINET: assign the device name and downloadPROFINETRequired

    Device name

    1. Right-click the connection between controller and coupler → Assign device name.

    2. Click Update list, identify the coupler by its MAC address (printed below the QR code) and click Assign name. The status must show “OK”.

    3. Compile and download to the controller, then switch the coupler off and on once.

    4. Go online: controller and coupler are green, IOR on the coupler lights steadily and BF is off.

    You do not set an IP address on the coupler; the controller assigns it. The GSDML suggests “pnio” as the name.

    Source: PN manual chap. 6.5.1

  8. 8PROFINET: parameters and first signalPROFINETRequired

    Set the measuring range, filter and substitute values per module in the device view: select the module → Properties → Module parameters. Then download again and switch the station off and on.

    For testing, create a watch table and enter the addresses. The address of each channel is in the Fieldbus tab – for your station and your start address.

    ParameterValueMeaning
    Analog voltage0–10 V = 0–27648Factory default on the PN2002
    Analog current4–20 mA = 0–27648Factory default on the PN2002
    Digital outputsPreset Lowset to 0 on bus failure

    The coupler can run as an MRP client in a ring; in that case, set the watchdog time above 200 ms (PN manual chap. 6.3).

    Source: PN manual chap. 6.1, 6.5.1; GSDML V2.43

  9. 9EtherCAT: install the ESI fileEtherCATRequired

    You will find the ESI file on the XB6S-EC2002 product page under “Downloads”. It comes in two versions: _BOOL shows each digital channel individually, _UINT combines 16 channels into one word. Install only one of them; both have the same device identity.

    SoftwareHow to install the ESI
    TwinCAT 3Copy the file to C:\TwinCAT\3.1\Config\Io\EtherCAT, restart TwinCAT
    CODESYSTools → Device Repository → Install
    Sysmac StudioRight-click the EtherCAT master → Display ESI Library → Install (File)

    The cable from the master always goes into IN; OUT goes to the next device.

    Source: EC manual chap. 6.3; ESI V3.0.13

  10. 10EtherCAT: scan the lineEtherCATRequired

    The order and type of the modules in the master must exactly match the physical setup (EC manual chap. 6.3).

    How to get the station into the master

    1. TwinCAT: I/O → Devices → Scan, select the network adapter, confirm “Scan for boxes” and “Free Run”. The coupler appears as a box with all modules.

    2. CODESYS: add an EtherCAT master, log in, then on the master Scan for devices → “Copy all devices to project”.

    3. Sysmac Studio: insert the coupler from the Toolbox, enter the modules in slot order under “Edit Module Configuration” and write the node address.

    Source: EC manual chap. 6.3

  11. 11EtherCAT: startup parameters and first signalEtherCATRequired

    Enter the measuring range, filter and substitute values as startup parameters on the coupler: module n (the first one has n = 0) under 0x2000 + n · 0x10. TwinCAT: Box → Startup → New; CODESYS: Startup Parameters tab. Then reload and switch the station off and on.

    The Fieldbus tab lists all objects (index:subindex) and parameter objects for your station.

    ParameterValueMeaning
    Analog voltage±10 V = −32768…32767Factory default on the EC2002
    Analog current0–20 mA = 0–65535Factory default on the EC2002
    Analog outputsClearset to 0 on bus failure

    RUN steadily on = OP. If ERR flashes at 2.5 Hz, the configuration does not match the physical setup (derived).

    Source: EC manual chap. 6.1, 6.3; ESI V3.0.13

  12. 12EtherNet/IP: set the IP addressEtherNet/IPRequired

    The factory default IP address of the coupler is 192.168.0.120. The easiest way to set the last octet is with the rotary switches ×100, ×10, ×1 (001–254, only with the power off), e.g. 0-2-1 for 192.168.0.21.

    To use a different network, use the Solidot IO Config Tool: scan for devices, coupler → parameters → network parameters, send and restart the coupler.

    Rotary switchesIP address
    000 (factory default)192.168.0.120 or the address last set via software
    001–254192.168.0.xxx (upper octets from the software setting)
    255–999as at the last start

    Hold the reset button on top of the coupler for 3 s: IP address, parameters and the saved module chain return to factory default (EI manual chap. 6.2).

    Source: EI manual chap. 3.1.2, 6.1, 6.2

  13. 13EtherNet/IP: configure modules with the IO Config ToolEtherNet/IPOptional

    With the generic EDS, you set measuring ranges, filters and substitute values not from the controller but in the IO Config Tool: select the module, change the parameters, send.

    There you also define whether the status word (4 bytes before the inputs) is sent along and what the outputs do in the IDLE state. With “Save configuration”, the coupler stores the module chain and later reports missing modules.

    The IO Config Tool is available further down this page under Downloads.

    Source: EI manual chap. 6.3, 6.6.1

  14. 14EtherNet/IP: integrate into the controllerEtherNet/IPRequired

    General (example in the manual: Keyence KV STUDIO)

    1. Register the EDS file XB6S_EI2002_V0.03 (on the XB6S-EI2002 product page under “Downloads”) in the controller software.

    2. Insert the coupler with its IP address, connection Exclusive Owner.

    3. Enter Input Data Size and Output Data Size – the values for your station are in the Fieldbus tab.

    4. Select the RPI (2–50 ms, factory default 30 ms), transfer, set the controller to RUN.

    The data follow one another without gaps in slot order; the Fieldbus tab shows which byte belongs to which channel.

    For KV STUDIO, there are also the modular files: with them, you enter the modules individually and set the parameters from the controller.

    Source: EI manual chap. 6.5, 6.6.2; EDS V0.03

  15. 15Modbus TCP: set the IP addressModbus TCPRequired

    The factory default IP address of the coupler is 192.168.1.120, port 502. Set the last octet with the rotary switches ×100, ×10, ×1 (001–254, only with the power off).

    To use a different network, go to the web interface: put the PC into the 192.168.1.x network, point the browser to the IP address, “Network parameters” at the bottom, save and restart.

    Rotary switchesIP address
    000 (factory default)192.168.1.120 or the address set in the web interface
    001–254192.168.1.xxx (upper octets from the web interface)
    255–999saved or factory default IP

    Hold the reset button on top of the coupler for 3 s until IOR and IOE light up briefly: IP address and parameters return to factory default (MT manual chap. 6.2).

    Show wiring “PC for configuration”

    Source: MT manual chap. 3.1.2, 6.1, 6.2

  16. 16Modbus TCP: check the station in the web interfaceModbus TCPRequired

    The Overview shows the plugged-in modules with their LEDs. Clicking a module opens its parameters (filter, substitute values, measuring range) – send, done.

    Configuration information shows the address table of each module. It is authoritative; the Fieldbus tab calculates the same addresses in advance from your planned station.

    Parameters cannot be changed while a master is exchanging process data (MT manual chap. 6.6.1).

    Source: MT manual chap. 6.3, 6.6.1

  17. 17Modbus TCP: set up the masterModbus TCPRequired

    In the master (PLC, HMI or CODESYS), set up the coupler with its IP address and port 502, response timeout e.g. 1000 ms.

    Then create one request per data type: digital inputs with FC 02, digital outputs with FC 15, analog inputs with FC 04, analog outputs with FC 16 – the start address and quantity for your station are in the Fieldbus tab under “All at once”.

    When reading, holding register 0 is analog input 0; when writing, it is analog output 0. Read back the analog outputs from 8192.

    Diagnostics: FC 03 from 24576 (0x6000), two registers per module (alarm code, channel).

    The manual does not specify a unit ID.

    Source: MT manual chap. 6.4.2, 6.5, 6.6.2

  18. 18Counters, encoders, temperature, pulse output, serial: what you need to setOptional

    The special modules do little on their own by factory default: usually an enable bit or an operating mode is missing. You set parameters as for the other modules (PROFINET: module parameters, EtherCAT: startup parameters, EtherNet/IP: IO Config Tool, Modbus TCP: web interface). Then switch the module or the station off and on again.

    The Fieldbus tab shows where count values, status words and control words are located in your controller.

    PT04A: by factory default, Safe Mode is set to “keep running” – if communication fails, the axes keep moving. For machines with hazards, set it to “decelerate to stop”.

    ModuleTo get it runningFactory default
    A40TM / A80TMSelect the sensor type for the whole module (e.g. TC K); measured value in 0.1 °CPT100, internal cold junction

    C01SPCommunication Mode (e.g. 1 = Modbus RTU master), interface and requests (node parameters)no function (Mode 0), 32 bytes

    After power-up, the PT04A shows error code 0x0601 until valid ramps and speeds have been written.

    PL20/PL20D: Power-failure retention is on by factory default, so a configured start value has no effect.

  19. 19If something doesn't work: error codesOptional

    The couplers report module errors with the same codes – PROFINET as an alarm in TIA, EtherCAT as an emergency in the master, EtherNet/IP in the status word, Modbus TCP from register 24576.

    CodeMeaningRemedy
    0x00C5No field voltage at the moduleConnect 24V/0V to the module
    0x0184Channel value out of rangeCheck signal and measuring range

    0x0FC1–0x0FC4Backplane bus: startup, timeout, module disconnected, checksumPlug the modules in flush, check for sources of interference
    0x2040Wire break at the temperature moduleCheck wiring

    By factory default, a module error makes the backplane bus stop data exchange for all modules until the error is cleared. With the coupler parameter “interactive”, the modules before the faulty one keep running.

Copper wires rated for 80 °C only. Cross-sections, ferrules and strip length: manual chap. 5.1 and 5.2.

Mounting step by step

  1. 1Choose the installation site

    Degree of protection IP20: the station belongs in a control cabinet.

    Mount the station vertically on a horizontal DIN rail (35 × 7.5 mm or 35 × 15 mm) and leave 50 mm of clearance above and below the modules. The wires run off upwards and downwards.

    Operating temperature −20 to 60 °C; above 45 °C the transistor outputs may deliver less current, above 50 °C the relays.

    Show clearances in the drawing

  2. 2Mounting the station

    Mount only with the power off.

    • Place the coupler on the DIN rail and snap it in (click).

    • Snap in each module individually and slide it to the left against the previous one until the backplane contacts engage and the fronts are flush. A P2000 goes in front of the first module it is to supply.

    • Fit the end cover on the far right – it is mandatory.

    • Place an end stop to the left of the coupler and to the right of the end cover and screw them tight.

    Show wiring “24 V supply”

  3. 3Replacing a module

    Switch off the power, loosen the end stops.

    • Slide the modules to the right of the module in question a little to the right.

    • Open the latches at the top and bottom with a flat-blade screwdriver and pull the module off towards the front.

    • Snap in the new module, slide the station back together, screw the end stops tight.

  4. 4Connecting 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.

    To release, press the push button with a flat-blade screwdriver (up to 3 mm).

    Signal terminals take 0.3–1.0 mm², the supply terminal on the coupler and P2000 0.3–1.5 mm².

Solidot XB6S-2002 Coupler kit 2A version
Solidot XB6S-2002 Coupler kit 2A version
The Solidot XB6S bus coupler is the head module of the XB6S slice series: it connects your controller to the attached XB6S input and output modules over the industrial fieldbus. The I/O modules plug onto the backplane bus, are detected automatically and supplied cyclically – so you build a decentralised I/O island close to the field instead of wiring every signal back to the PLC.🏭 Typical applicationsMachine and plant building: compact I/O islands right at the machine, connected via the existing fieldbus.Conveyor and intralogistics: distributed sensors and actuators along long runs, without star wiring back to the central controller.Packaging and special machinery: fast, deterministic I/O – up to motion-grade depending on the protocol.Retrofit: extend existing plants with decentralised I/O, matched to the installed control system.⚙️ Key specificationsTwo Ethernet ports 10/100 (RJ45), daisy-chain capable for line topology.Up to 32 XB6S expansion modules on the backplane bus, automatic detection.24 V DC supply (permissible 18 – 36 V DC), input current 600 mA, passive cooling.Configuration via the built-in web browser access, IP20, −20 to +60 °C.Pluggable spring terminals, compact 106 × 43 × 61 mm.🌐 Protocol variantsThe coupler is available with different fieldbuses to match your control world: PROFINET, EtherCAT, EtherNet/IP or Modbus TCP. All variants use the same hardware platform and the same XB6S module range – you just pick the protocol that fits your controller.🧩 Which variant?PROFINET – for Siemens controllers and most European PLC worlds.EtherCAT – for Beckhoff and CODESYS systems, fast and deterministic applications.EtherNet/IP – for Rockwell/Allen-Bradley environments.Modbus TCP – vendor-neutral, ideal for SCADA, gateways and simple integration.🔧 Mounting and dimensions35 mm DIN rail, dimensions 106 × 43 × 61 mm. Snap on without tools, attach I/O modules to the right.🏷️ Manufacturer and reliabilitySolidot (Nanjing Solidot Electronic Technology) specialises in decentralised I/O and fieldbus technology.

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.
