The counter is incremented at 100ms intervals after GOT is turned ON.
(The time elapsed after GOT is turned ON is stored in 100ms units.)
(1) When setting the LH order to [32bit Storage] for the communication detail settings
The lower and upper bits are stored in SD0 and SD1 respectively.

2: Framing error
4: Communication message error
6: Clock data setting error
•Other station (Communication error that occurred on another GOT when multiple GOTs are connected)
101: Parity error
103: Overrun error

If a wrong day of the week is set by the clock data setting command, the clock data will differ from the time displayed on the utility.
Example: When October 01, 2009 (Tuesday) is set by the clock data setting command (the actual day of the week is Thursday)
"2" is stored to SD9 although Thursday (THU) will be displayed on the utility time display.
