6.5 Diagnosis of the DeviceNet profile communication
The protocol variant DeviceNet profile also has its own fault
code. The composition of the Response Message in the event
of a fault is as follows:
Byte Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
0 Status byte
1
2 Fault code
3
4 Extended fault code
5
6
7
Fault code Meaning
0 No fault
1 Command Message type not valid
2 Command Axis number not valid
3 Response Message type not valid
4 Command Axis number not valid
7 Parameter fault (see extended fault code)
With fault code 7, there appears an extended fault code
instead of the work data in byte 4 of the Response Message.
Take this into account when programming your PLC/IPC
(ifĂnecessary, end update with RMT = 0).
