I want to monitor the status of all the PLCs in one SCADA system. For this to happen what kind of software and hardware i have to buy ? with regards, nand gate

If not than I prefer you to go for S7-1200 PLC where you can get easily access though Net. Please go throgh the below link. How can I access remotely to the S7 PLC 1200? I hope it will help you much better.

Note that other non-PLC options are also available.. unless the sky is the limit for your budget. Happy hunting. w

S7 200 PLCs are already installed (they were installed couple of years back and they are fully in operation. So replacing them with S71200 is out of question). What is the cheapest possible option for this ? with regards, nand gate.
