Schneider Electric VW3A3310d b Configuring Modbus messaging

18. Setup using PL7

b 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 139.160.69.245

Subnet mask 255.255.254.0

Gateway address 139.160.68.1

Drive IP address 139.160.69.242

Xway address IP address Protocol Access Mode

1 1.101 139.160.69.242 MODBUS MULTI
