SLC 5/03 and IAI PCON (Modbus)

[gregi]

Need to talk to 2 servo drives by IAI (PCON)from SLC 5/03. What do I need , how easy it is? Need just change position register value and monitor controller status.

I don't think a 5/03 can do Modbus Directly. You will need something like This Module from Prosoft:

Otherwise, I believe the later series Micrologix processors can be configured as Modbus Master devices.

The very newest OS302 Series C FRN 11 firmware for the SLC-5/03, -5/04, and -5/05 controllers can configure the Channel 0 serial port as a Modbus RTU Master.

If your SLC was built in the past 12 years or so (i.e. not the Series A hardware), it can be upgraded with a firmware plug, part number 1747-OS302.

** I learned that some of the FRN11 firmware plugs were mis-programmed with FRN10; it might be a few days before that gets sorted out and you can buy those upgrade plugs again.

You can also use a Prosoft MVI46-MCM module, which are very popular Modbus interfaces.
