We have 12 PLC's(6 main and 6 standby)that are linked by serial cable through genius bus controllers to an old SCADA system(Fincor interrogator) that cannot be edited and is no longer serviced by anyone. We have made a lot of changes to these newspaper presses this last year so some of the I/O is now used for other things and there have been additional processes added that we can't bring into the existing SCADA. We want to tie into A new SCADA system Like our RSview 32 we use for other things. My question is what is the best way to connect to this serial network?
