I need to replace an old Mycroadvantage system that is connected to a Moore APACS DCS (now Siemens) with iFix (or Fix32) HMI software. I was thinking of using Intellution (now GE Fanuc) APX driver supporting both 32 bit M-Bus and Ethernet communication with APACS (API Run Time from Siemens required). Existing system has 16 Bit M-Bus interface, no Ethernet communication module. Is there a better communication solution, such as iFix OPC Client driver? Could someone provide an assistance?
