Detailed Description

Mandatory for CANopen, resides in object dictionary, index 0x1001.

Error register is calculated from internal bitfield variable, critical bits. See Error status bits and Emergency producer/consumer for error condition macros.

Internal errors may prevent device to stay in NMT Operational state and changes may switch between the states. See NMT control bitfield for NMT internal state. for details.
