DINT
indication that a device has failed:
• There is 1 bit for each address on the DeviceNet network (0 -63).
• The position of a bit = address of a device.
• If a bit = 1, then the device at that address has failed.
DeviceFailureRegister
SINT[8]
indication that the data size of a device does not match the amount of
memory allocated for the device in the scanner:
• There is 1 bit for each address on the DeviceNet network (0 -63).
• The position of a bit = address of a device.
• If a bit = 1, then their is a mismatch with that address.
AutoverifyFailureRegister
SINT[8]
indication that a device is idle:
• There is 1 bit for each address on the DeviceNet network (0 -63).
• The position of a bit = address of a device.
• If a bit = 1, then the device at that address is idle.
DeviceIdleRegister
SINT[8]
indication that a device is online:
• There is 1 bit for each address on the DeviceNet network (0 -63).
• The position of a bit = address of a device.
• If a bit = 1, then the device at that address is online.
