count of I/O scans 10 ScanCounter 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.
