Hi

I want to send serial data using a S71500-2 PN plc via a IM151-3 PN IO station to an ASCII card module. The hardware configuration shows that the plc has accepted the download. In the software, when I trigger the REQ on a positive Edge on the S_Send FB no data gets transmitted by the block. I have double checked the settings in the hardware config. I have created a data block wich houses all the data that needs to be send. There are no Error or Done acknowledgements. RJ21Any ideas?

Hello RJ21;

Welcome to our forum.

We would like to help you out, but we need to visualize what you have configured and programmed in order to do so.

Please prepare some screenshots of your hardware configurations and programmed functions, you can try to collect them in a single Word or PDF file that contains all of them so you can attach it here in your next post.

Hope this helps,

Daniel Chartier
