Hi there,
I have an application with a CompactLogix processor (L32E) polling a remote site via a 9300-RADKIT modem. I have no problem to connect to the remote site usign a "ATDT" command line in an ASCII string (with block AWA). I have no problem to exchange data from remote site to local PLC.
My problem is: I cannot hang-up the phone line. I tried a "AWT" command via ASCII string with the string "+++", I also tried the commands AHL with a AND mask and OR mask as per the example in the "SCADA" manual from Rockwell Automation. Nothing works.
Can somebody help me on that issue ??
