1. Hardwareverbinding
Compatible PLC: Inovance H3U
The Modbus RTU protocol uses serial communication. This example PLC model employs RS232 communication.
2. PLC-communicatieparameters
2.1. Instellingen seriële poort
Provided by the PLC engineer.
The serial port parameters for this Inovance PLC are:
Baudrate: 57600
Gegevensbits: 8
Stopbits: 1
Parity Bit: NONE
3. Gateway Configuration
3.1. PLC Connection Setup
Drag an Inovance node from the left pane. Double-click to open the settings page and configure as follows based on the PLC’s serial parameters:
Protocol: Selecteer Modbus RTU
Seriële poort: RS232
Baudrate: 57600
Gegevensbits: 8
Stopbits: 1
Pariteit: None
Timeout: -1
Serie: H3U
Station ID: 0x0B
Formaat: ABCD
3.2. Configuratie gegevenspunt
Enter the data points to be read into the parameter list of the Inovance node. Once configured, the node will automatically read data from the PLC at the specified frequency.
Datapunten worden meestal geleverd door PLC-engineers. Nadat u de puntenlijst hebt verkregen, vult u de gegevenspunten in volgens het vereiste formaat van de gateway. Raadpleeg voor specifieke details over de toewijzing:

This example reads data from addresses D6000 and D6002. In the parameter list, enter the address/name/data type in sequence. The data is read cyclically every 2 seconds, as shown in the figure:
3.3. Testen
Click Deploy and observe that data is printed every 2 seconds. The read data point results are: D6000:0 D6002:0. Communication successful!
