General

This document will briefly explain about communication settings between PLCs with drives, how to control the drives from PLC using the control function blocks.

Each input and output of the function blocks are explained in the integrated documentation in the library.

This library is released for the following products:

  • AC500 processor modules

  • ABB Drives:

    • ACS380, ACS480, ACS580, ACH580, ACQ580, ACSM1, ACS880, DCS550, DCS800, DCS880. Other drives may still work, but are not tested.

    • To use the control blocks the Communication Profile must be “ABB Drives Profile” or “ABB Drives Profile enhanced”

  • Fieldbus Adapters: FENA-01, FENA-11, FENA-21, FSCA-01, FCAN-01, FECA-01, RETA-01, RETA-02, RCAN-01, FPNO-21, FMBT-21.

    Fieldbus adapter support is dependent on the drive and for more details refer the corresponding drive manual.

Drives Library will support following protocols for the communication:

  • Modbus TCP (onboard ETH1 and ETH2 ports)

  • Modbus RTU (onboard COM1 port)

  • PROFINET (using communication module CM579-PNIO)

  • EtherCAT (using communication module CM579-ETHCAT)

  • CANopen (onboard CAN port)
