Setting the Clock with a User Program
A user program can write the clock data from an operator interface without using WindLDR by using special data registers D8015
to D8021. Undefined values are stored in special data registers D8015 to D8021. Always store an appropriate value before turning
on M8016, M8017, or M8020.
