“MODBUS” (available on “PRO” models only)
Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for
use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard
communication protocol, and it is now a commonly available means of connecting industrial electronic devices.
Set the communication speed according to the PLC system available. Set the ID assigning an UNIQUE address to
avoid conflicts.
Connect the PLC through blocks 17 and 18 and enter an ID number available, baudrate (communication
speed) and communication mode (i.e.: 8N1, data bit, parity check and stop bit).
