i have been dumped an unfinished project with no budget left and i have been tasked to find a way to connect a new Siemens PCS7 system with profinet to 2-3 existing A-series mitsubishi systems.
we have limited I/O availability on the mitsubishi side, so i dont think an old school direct multicore connection is going to be viable.
the A series is connected to a SCADA system, so an OPC is an option, but turning the SCADA PC off would then stop the new process.
what options can people suggest that isnt going to require buying discontinued parts off ebay?
