Hello,

I've created a TCP driver that receives "telegrams" from a DigiTemp-E receiver. I've tried rooting around forums and inductive university, but I am getting lost trying to find how ignition receives this data. When it is set up in a PLC, a 128 bit Sint array is created to receive it, and I'm having trouble duplicating that as Ignition limits me to a 4-byte array.

I read that people write a "listening script" but I only know as much about python as I've learned designing screens. Is there a video or page in the user manual I'm overlooking that goes a little more into detail with receiving ASCII characters?

I'd say welcome to the forums, but your choice of user name jumped out at me, negatively. Consider asking a mod to help you change that to something less insulting.

This a professional forum, and while anonymity is sometimes necessary, proper names and profile information help make the impression you need to get help from volunteers.

Oops, sorry.

If you're already copying the SINT into a PLC, you could retrieve it as a string from the PLC using an OPC tag
