Client
The Modbus TCP client in Proview allows you to connect to equipment which acts as Modbus TCP servers, such as remote I/O, PLCs etc.
Instructions
Here are the steps required to add a Modbus TCP client in Proview:
- Create a Modbus_Master module for your node
- Under the Modbus_Master module, add a Modbus_TCP_Slave
- Configure the Modbus_TCP_Slave module with the ip/port for your plc (e.g. 192.168.1.60 / 502)
- Configure a Modbus_Module under the Modbus_TCP_Slave for each function code you want to use (Read_Coil, Read_Registers etc).
- Configure the channel objects of the appropriate type for each Modbus_Module
Now you can connect each of the channel objects to the appropriate variables in your plant hierarchy.
