I would need information concerning A-series PLC communication protocols. We have a modernization project whhich consisting of different type of Mitsubishi PLC CPU types: A1S, A2N, A3N, A3 and A273UH. We have thought about a possibility to use Red Lion G3 panels to make gateway from those devices to Siemens S7 side. The problem is that I haven't information about the Mitsubishi communication. There is mentioned A -series and A1S on Red Lion Crimson, but I don't have information are the other supported?

Does someone know if the A2N, A3N, A3 and A273UH have same communication protocol what A1s has?

You could use the NETB cards, this will allow you to transfer data from/to all plc's in the A range then use just one HMI, however I'm not sure how long or even if mitsubishi still support A series PLC's

The NetB card is configured in the setup you select ranges in the "B" & "W" memory areas, also using NETB you can use passthrough to all plc's for programming.
