61.4.5 SD devices
The SD devices are word devices into which GOT communication errors (error codes), clock data and other information
are stored.

List of SD devices
The following lists the SD devices (virtual devices inside the GOT).
*1 For details and corrective actions for the errors (error codes) that are stored into SD2, refer to the following:
■ Details and actions for errors (error codes) stored into SD2
*2 If a wrong day of the week is set by the clock data setting commands, the clock data will differ from the time displayed on the
utility.
Example: When June 1, 2004 (Thursday) is set by the clock data setting command (the actual day of the week is Tuesday),
"4" is stored to SD9 although Tuesday (TUE) will be displayed on the utility time display.
POINT POINT POINT
The side where virtual devices are set
System : Set on the system side.
User : Set on the user side (by sending request messages from host or using the touch switches, etc.
on the GOT).

SD1
100ms counter (32bits)
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) When setting the HL order to [32bit Storage] for the communication detail settings
The upper and lower bits are stored in SD0 and SD1 respectively.
