MODBUS communication

4.6.1

MODBUS support

The MODBUS communication uses the Ethernet port (MODBUS TCP) and consequently is only available
for LBK ISC BUS PS and LBK ISC-02 controllers.
4.6.2

MODBUS communication enabling

In the LBK Designer application, click on Settings > MODBUS Parameters > ON to enable the feature.
Within the Ethernet network, the controller acts like a server. The client must send requests to the IP
address of the server on the MODBUS listening port (default port is 502).
To show and change the address and the port, click on Settings > Network Parameters and Settings >
MODBUS Parameters.
