Integration of SLC 5/03 and soft starter

Dear All,

I want to integrate AB SLC5/03 PLC with Altistart48 soft starter.
SLC 5/03 works on DH485 protocol and Altistart48 soft starter work on modbus protocol.
There is any allen bradley protocol converter available.
If yes, than please give its catalogue number.
If no, than please suggest alternative.
Please reply soon.

How new is your SLC5/03? If it is a series C FRN 10 or greater then channel 0 supports Modbus RTU Master.

If not then a ProSoft module should work for you. See link below.
