Can the Altistarts and Altivar sotstarters ATS48, ATS22, ATS480 be controller via Modbus as well use remote HMI at the same time?
Remote panel as well as PLC with modbus - both represents modbus masters.
Modbus communication from its principle does not support two masters.
The best solution to share one slave (ATS) between two masters (PLC and HMI) is to use modbus port multiplexer. This device alternates modbus requests, once between ATS and PLC and second time between HMI and ATS and so on.
