This is my first time posting. I am using a SLC5/03 since we had an extra one laying around to mess with ascii commands before hooking up to the main PLC on the line. I am trying to communicate with a keyence vision system whcich I was successfull with communications with the pc to the vision system. I have read the posts of ascii commands for communications on here and I switched channel 0 to user instead of system and cleared the buffers.
I have started to write some ladder logic using the AWA and a few other commands. The problem I am having is that the error message on the command is 04h which means its in system mode not user. I have changed it to user mode, but the ER on the command is not green so it acts like it is not true. When i toggle the b3 bit for the rung to come true the command does nothing EN nor DN comes green.
Any suggestions?
I can post the program if needed it is just 3-5 rungs long trying to get familar with ascii since this is my first encounter with it.
Thanks,
Brad
