DeviceNet device diagnostics

MacState: if ≠ 0, this DeviceNet device is not participating correctly in the process data traffic
CouplerState: for Beckhoff Bus Couplers, the terminal communication of the Bus Coupler may be disturbed or diagnostic data may be present if ≠ 0

DeviceNet slave devices feature different diagnostic variables that describe the DeviceNet communication state and can be linked in the PLC:

	We recommend monitoring the following process data during each cycle: MacState: if ≠ 0, this DeviceNet device is not participating correctly in the process data traffic CouplerState: for Beckhoff Bus Couplers, the terminal communication of the Bus Coupler may be disturbed or diagnostic data may be present if ≠ 0
