Mike6158 & ad2002,
As always, it's a pleasure to see your inputs. Anyway, Schneider Electric's Premium PLCs does not offer for one to simply connected to the Modbus RS485 network to be able to configure any PLCs on that network like it's legacy Quantum's PLCs does; however, Modbus Ethernet does...
Mike6158,
Good feedbacks on the Siemens PLCs....I take it that you haven't came across any ABB AC800F/AC800M before?
Anyone else's has any things to add to either ABB or Siemens PLCs?
Thanks in advance,

Any way, I would like to ask your opinion on the following PLCs:
I have to choose between the ABB AC800F or Siemens S7 400 PLCs for my current project. Initially, I was going...
jwmccoype,
Thanks for your valuable contribution. yes, I do agreed with you on the salesman's tale; that is why I posted this question hoping to get as much feed back as possible prior making my decision on this design.
Hi all,
I am considering to use the DeltaV DCS from EMERSON for my up coming project; and DeltaV offers a Modbus serial link to PLCs. I am also planning to use Schneider Electric's Premium PLCs to be connected to the DeltaV via Modbus Ethernet. Therefore, I would need to use a Serial to Modbus...
I am using two PLC-5/80 as a redundant processors that is processing 7 SLC-5/04 I/O data through Channel 1A on the PLC-5 via DH+ communication. Also, Channel 1B is processing 3 remote I/O racks via ControlNet I/F module. And the communication between the PLC-5 CPUs are also ControlNet as well. A...
