Hey Guys!

I've run into a rather annoying little problem with the Siemens AG_RECV block (using a CP343-1) when trying to read data back from an RFID Reader.

It seems as though the NDR bit stays low until the entire buffer is full. At this point my received data will be in variable lengths so I cant really lock down my buffer size. Also, for some reason, if I try and set my buffer size to anything less than 130 Bytes if get a 80B1H error code meaning "Destination" area invalid.

Does anyone happend to have a work-around for this silly silly issue?

Ya just got to love those crazy cats at Siemens...

Cheers!

Hi R.K.

I've run into similar problems also. I think this might help:

We solved the problems by always sending a same length message, from a server in this case.
