I have a number of machines running on Omron CPM2A PLC that i wanted to link up to a PC for machine status monitoring and setting downloading and uploading.
I planned to use rs422 since Omron only has one RS232 and one proprietary peripheral port. What i can do is:
Use rs232->rs422 converter at PC side, then at each PLC side use Omron rs422->rs232 converter to do multidrop.
However because of the low Bandwidth, i am thinking of alternatives. Such as using field bus like DeviceNet. The problem now is to convert the 2 different signals.
Anyone has experience in doing that??
Suggestion can be other means than DeviceNet.
Thanks advance for the help.
