Hello eveyone!
I wonder if any one could offer any advice on a pooject I'm about to setup.
I currently have 5 separate plc systems all using 5/03 processors. I wish to use a common LOI to display plant status and for paramater setting. The problem is I only have a Siemens OP270 10" for this purpose. I know I can connect the OP270 directly to one of the 5/03's and network all PLC's then use mesaging from each of the PLC's to the "master" or sit the OP270 directly on the DH485 network and monitor each PLC individually. However I know the limitations of DH485 and am unsure if either of these solutions is possible in the real world, what do you think?
Also how would you physically connect 5 SLC 5/03's together and still have a spare RJ45 socket left to connect my laptop to?
Or am I miles off with what I'm thinking and should I try a differnt approach?
Any help would be much appreciated.
Cheers, kris
