Modbus-Teilnehmer und Kinco HMI MT4220TE
Kinco HMIs are an inexpensive visualization and operating option for Modbus devices. Modbus devices can be visualized and operated very easily with Kinco HMIs. Select your desired connection type to see how the HMI and Modbus PLC are connected to each other.

The programming software (German) for the Kinco HMI is completely free of charge. The programming software is available as a free download from the respective HMI. Below you will find an overview of all Kinco HMIs. Simply select the right size for your visualization project.

Connection of the Modbus server (slave) participants via Ethernet

A Modbus TCP/UDP server (slave) can be easily connected to the Kinco HMI via Ethernet. You can connect the PLC either via a direct LAN connection or via a hub or switch. This allows you to visualize and operate several participants on the Kinco HMI via the LAN.

All Kinco HMIs in our online store have a standard RJ-45 Ethernet connection for this purpose.

Driver configuration for Modbus TCP via Ethernet in the Kinco HMIware

The appropriate driver in the Kinco HMIware for connecting Modbus servers (slaves) via Ethernet is the Modbus TCP slave driver.
Alternatively, the Modbus UDP slave driver can also be used if the end device also supports Modbus UDP.

All Kinco HMIs with an Ethernet connection can communicate with Modbus devices via the Ethernet module. To do this, a project must be created accordingly in the Kinco HMIware, the communication configured and the project transferred to the HMI. The configuration is carried out in the following steps.

Create a new project in the Kinco HMIware or open an existing project
Drag the HMI used in the HMI tab into the project
Under PLC, drag the Modbus TCP slave into the project
Open the configuration of the LAN by double-clicking on the PLC, then "Network Device Settings"
Add the PLC under "Add" and configure the IP of the PLC
Add the HMI under "Add" and configure the IP of the HMI
Close all open windows with Ok
Create screens and objects that are linked to variables in the PLC (more on this under Addressing)
Compile the project and transfer it to the HMI via download

Configure the communication between Kinco HMI and a Modbus TCP server (slave) via Ethernet in the Kinco HMIware. Make sure that the station number is correct.

Note: In the Kinco HMIware, the Modbus addresses start at 1, in many Modbus devices at 0. Therefore, there is often an offset of one position in the addressing. In the Kinco HMIware, you should then add +1 to the address.

Connection of the Modbus client (master) participants via Ethernet

Kinco HMIs can also be operated as Modbus TCP servers (slaves). In this case, another participant (client or master) accesses the data in the HMI and writes and reads the internal variables there. These internal variables can then be used for visualization and operation on the HMI. You can connect the CLient (master) either via a direct LAN connection or via a hub or switch.

All Kinco HMIs in our online store have a standard RJ-45 Ethernet connection for this purpose.

Driver configuration for the HMI as a Modbus TCP server (slave) via Ethernet in the Kinco HMIware

To operate the HMI as a Modbus TCP or Modbus UDP server (slave), you do not need to configure any external devices in the Kinco HMIware. It is sufficient to configure the communication protocol of the network in the Kinco HMI. You do this in the following steps:
1. Create a new project in the Kinco HMIware or open an existing project
2. Drag the HMI used in the HMI tab into the project
3. Open the LAN configuration by double-clicking on the HMI, then "Network Device Settings"
4. Add the HMI under "Add" and configure the IP and station number of the HMI
5. Under "Comm Protocol", select Modbus TCP Slave or Modbus UPD Slave
6. Close all open windows with Ok
7. Create screens and objects that are linked to variables in the PLC (more on this under Addressing)
8. Compile the project and transfer it to the HMI via download
Configure the communication between Kinco HMI and a Modbus TCP server (slave) via Ethernet in the Kinco HMIware. Make sure you have the correct station number so that your client can access the HMI.

Kinco HMI elements

Kinco HMIware provides a wide range of elements for visualizing and changing PLC data. These include, for example, switches, lamps, input fields and much more.

For operation as a Modbus slave, these elements are linked to internal variables of the HMI. The Modbus masters can then access these variables themselves and read or write them.

Serial connection of Modbus devices via RS-232 or RS-485

You can easily connect serial Modbus devices to the Kinco HMI via a serial interface. You can often connect them directly to the programming cable of the Modbus device. The small 4'' Kinco HMI has one serial connection, devices from 6'' have at least two serial interfaces. Serieller Anschluss am Kinco HMI

The serial ports of a 7" Kinco MT4424TE HMI support both RS-232 and RS-485 communication

RS-232

RS-232 is a serial communication protocol for a point-to-point direct connection. A Modbus device can be connected directly to the HMI via RS-232. All physical ports on the Kinco HMI support RS-232 communication. The physical connection COM 0 has an additional RS-232 connection (COM 2) on pins 7 (Rx) and 8 (Tx). A special serial cable is required to connect this to the Thinget PLC.

RS-485

RS-485 is a protocol for serial communication with several participants. You can use RS-485 to allow several devices to communicate with the HMI via a single serial connection. Kabel Kinco HMI und Modbus RS-485

Driver for Modbus devices via a serial connection in the Kinco HMIware

The appropriate driver in the Kinco HMIware for connecting Modbus devices via the serial interface is the Modbus RTU driver.

Alternatively, you can also use the Modbus ASCII driver if your end device only supports Modbus ASCII.

All Kinco HMIs can communicate with Modbus devices via the serial interface. To do this, a project must be created accordingly in the Kinco HMIware, the communication configured and the project transferred to the HMI. The graphical configuration is carried out in the following steps.

Create a new project in the Kinco HMIware or open an existing project
Drag the HMI used in the HMI tab into the project
Under PLC, drag the "Modbus RTU" device into the project
Now open the "Connector" menu and use "Serial Port" to drag a serial connection into the project
Connect the serial connection to COM 0 or COM 1 on the HMI (special cables are required for COM 2)
Connect the serial connection to COM 0 on the PLC
Important: Double-click on the PLC to configure the Station Number
Double-click on the HMI to configure the corresponding serial COM port
Compile the project and transfer it to the HMI via download

Configure the communication between the Kinco HMI and several Modbus devices via the serial interface in the Kinco HMIware - the configuration of the Station Number is important.

The configuration of the serial interface of the Kinco HMI can be accessed by double-clicking on the HMI. The type of communication (RS-232, RS-485-2, i.e. two-wire or RS-485-4, i.e. four-wire) is configured here. You can also configure the baud rate and other parameters here.
