RS232 comms to MicroLogix 1200
I am trying to communicate between a Micrologix 1200 and a vision system VB program.
Current situation is that clear the buffers (ACL) and send a "1" to request the vision system to take an image. According to the result the program returns a "2" which I have been trying to pick up with an ARL command - But I receive nothing. I am thinking that it is a timing issue - that I am missing the short pulse of the two. Has anybody any experience of a similar situation? All help gratefully received. |
