Soft starter
ATS48
The ATS48 is connected to an Ethernet network via an ETG100 gateway.
Communication is transparent between the Ethernet and Modbus serial line therefore the I/O scanning service
can directly access the ATS48 data.
The table below details the interface between the starter and the DFB into PLC application.
