cltoh77 Posted July 30, 2005 Report Posted July 30, 2005 Hi all, Currently had a project, which request connect A1A CPU to 2nd scada system. I intend to add a RS232 module (AJ71C21 S1), please advice what should be take note. And if the RS232 module set up ok, does it mean that the scada system can "chit -chat" with PLC CPU just like through comm port on CPU module? Thank you for any input. Regards, cltoh77
panic mode Posted July 30, 2005 Report Posted July 30, 2005 you can add RS232/422 or ethernet module and let pc communicate with the plc. just make sure your software supports it.
