Micrologix 1500 ASCII Receive Problem

I have a Micrologix setup to receive ASCII on Channel 1. I know the device is outputting data as: LINEAR FAULT OPEN[CR][LF]

The file attachment has the rungs and the Channel 1 configuration I am using.

I can receive data to my laptop at 19,200 8,1,N

I am only using the TX & RX wires for channel 1. I am receiving data from the PLC to the other device so I know they are talking, but I am not seeing anything coming into the PLC.

Any help would be appreciated.

Thanks,
Don

Provide String length & test in ARL Instruction

String Length (.LEN) is the number of characters you want to read from the buffer. The maximum is 82 characters. If you specify a length larger than 82, only the first 82 characters will be read. (A 0 defaults to 82.) This is Word 1 in the control block.

It should read the whole string with 0 there. I have used this logic before several times with Barcode reader so I know it works. I'm wondering if it has something to do with the cable. Can I just use TX & RX or do I have to use other wires?

No, but I will give it a try.

That was it! I had not thought about that because it was sending data to the device. (2 way communication) I was also receiving the data to my laptop. I guess it through me off!

Thanks for the help! Hope this will help someone else sometime!
