the clock address dialog box shown below appears. Always set an address
when using the clock function (data displays, screen display history, or alarm
history).

Set the area and the address of the first word from which to read the clock data.
A Clock Data Area will be defined consisting of 4 words starting at the specified
address.

Set a comment for the address used to define the Clock Data Area. Up to 16
character can be input.
