Issue:
Connect a remote keypad and a communication network to the ATS22 / ATS48 soft starter.
Product Line:
ATS22/ATS48 soft starters
Environment:
All models, All serial numbers
Cause:
Instructions for this type connection can not be found in current literature.
Resolution:
It is not possible to have an ATS22 or ATS48 connected to multiple server devices via Modbus RTU. The ATS is a Modbus client and as such will follow commands from a server device over the network. The remote keypad is a modbus server and their controller on their network is also a modbus server. It is not possible for a Modbus client to follow commands from multiple servers simultaneously. This type of configuration is not possible.
