Hi everyone,
I'm getting a little bit experience in automation world, and now in PLC programming, specifically on Allen Bradley. I'm communicating a Micrologix 1400 with an external device via CH2 of PLC, sending periodic ASCII codes. My program yesterday seems to be fine, but today is not working, because serial port is not writting on the external receiver. When I download my program on PLC just the first scan works properly, but on second I've got no results.
Any ideas of this problem?
Attached you will find my program.
Thank you,
Alberto Parra.
