(Note-1): The state of a device is not in agreement when the device of a remark column is turned ON/OFF directly. In addition,
when the request from a data register and the request from the above device are performed simultaneously, the
request from the above device becomes effective.
(Note-2): It can also be ordered the device of a remark column.
(Note-3): Do not use it as an user device. It can be used as a device that performs automatic refresh because of area for the
reserve of command signal.
POINT
The device of a remark column turns ON by OFF to ON of the above device, and
turns OFF by ON to OFF of the above device.
The command signal cannot be turned ON/OFF by the PLC CPU in the automatic

M2053. Use the above devices in the case.
And, it can also be turned ON/OFF by the data register. (Refer to Section 4.2.8)
