Receive HEX with JAZZ

[Graeme]

Hi,

I am doing a small project that I need the receive an ACK(06h) or NAK(15h) from a printer to confirm or deny that it has received the string that was sent to it.

I can send the hex values required, but am having no luck with figuring out if/when the Jazz has received the ACK or NAK?

If anyone can shed any light that would be much appreciated.

Thanks,

Graeme

Did you check the example "Card read - display ASCII". You can find it in U90Ladder > Help menu Sample... Communication.

If you receive really text "Ack" and NAK, it can work practically as it is.

If you receive the special ASCII codes for ACK and NAK, you just can compare in Ladder the received code and drive variable "List of text" on display.
