Hi,

I have e problem. I have to send some simple serial command to a ticket printer (and a barcode reader).

I Have Step7 5.5 sp4 HF8, a couple of 414H cpus and I have to communicate via a CM Ptp card (6ES7 137-6AA00-0BA0) mounted con a ET200SP over a profinet network.

I can't find anything but Tia Portal discussion. Beeing a 400H system, Tia is not supported.

Can someone help me understanding hardware settings and wich FB to use?

Does anyone have an example project to share?

Thank you so much.

Michele
