Communication protocol

This chapter describes the Modbus/RTU communication protocol

for the adapter module.

Modbus/RTU is a variant of the Modbus family of simple, vendor

neutral communication protocols intended for supervision and

control of automation equipment.

The FSCA-01 RS-485 adapter module acts as a Modbus/RTU

slave with support for ABB Drives and Transparent profiles. The

Modbus commands supported are listed in section

Function codes

on page 70.

You can find more information on the RTU transmission mode and

cabling in MODBUS over Serial Line Specification and
