CQM1H and supervisor solutions

3 posts in this topic

Hello. I m looking for a solution to monitor - alarms, process synoptics etc. - a process controlled by a CQM1H. The major question is "how to communicate with that CPU?" For example, Intouch proposes a Host link driver over serial interface. But then, the baud rates is 19200. Omron proposes a Controller Link card at 2Mbauds but that solution also requieres a expensive OPC driver to communicate with other supervisor than CX-Supervisor. Any other idea ?

If you don't have many points to monitor I'd recommend a serial connection with CX-Supervisor. Youre limited to 19200 baud but that should be lots for most applications. If you have a heavy demand for data logging and actual process control from the Scada then Controller Link may be the solution, at a much higher price.

Not true. Citect will give you a complimentary disk - no charge - containing FINS Gateway for communication with Controller Link if you purchase Citect. OPC is not required. Citect
