EEK ROGRAMMER
Differences in the week programmer instructions
There are four types of week programmer instructions: the WKTIM instruction, the WKTBL instruction, the WEEK instruction,
and the YEAR instruction. The initial values of the WEEK and YEAR instructions, such as the day of the week, ON time, OFF
time, and special dates, can be easily configured in the dialog box for the instruction. The initial values of the WKTIM and
WKTBL instructions must be configured using data registers.
