SD devices

The SD devices are word devices into which GOT communication errors (error codes), clock data and other information are
stored.
■1. List of SD devices
The following lists the SD devices (virtual devices inside the GOT).
Address
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.
