Hi,

I am working on a RFID project and I am not familier with this module.
I am using the manual (http://literature.rockwellautomation.com/idc/groups/literature/documents/um/56rf-um001_-en-p.pdf) to implement example codes.
As a first step I am trying to get the system information. For some reason I am getting two negative values for the Max Block Number(-7 it has to be 249) and IC Ref(-125). The data type of the interface block is SINT. This is something that I am reading from the block and I dont understand why I get negative values...

So anybody has experience on programming 56RF-TG-30-2KB ?:)

Yes I did set the unit to run mode. But still reading -7 for number of blocks in the unit.
Not sure what is going on here.
