Example 6:
In the event of an error: Reading an object on a device without PCP
(slot 2, index 0080)
Since the addressed device does not support PCP, the request is rejected immediately. A
message is sent by DP/V1, whereby error code D2 stands for "Terminal does not have
PCP". See also Section "Error codes for DP/V1 and VC1 communication" on page A-3.
