10.3. Configuring Modbus messaging
To use Modbus messaging in PL7, the "IP address", "Subnet mask" and "Gateway
address" parameters must be configured in the "Messaging" tab in the PLC Ethernet
module configuration screen.
Data entered in the "Connection configuration" box is used to manage the PLC Modbus
messaging service, but has no effect on IO Scanning which is an independent service.
Example:
PLC IP address
Subnet mask
Gateway address
Drive IP address
1
Xway address
IP address
1,101
