Explanation of function and operation
1. 16-bit operation (TZCP)
The lower limit and upper limit comparison time (hour, minute, and second) are compared with the time data (hour,
minute, and second) stored in three devices , +1, and +2. Three devices starting from turn
ON or OFF according to the comparison result.
Operand type Description Data type
Specifies "hour" of the lower limit comparison time (hour, minute, and second).
(Three devices are occupied.)
16-bit binary
Specifies "hour" of the upper limit comparison time (hour, minute, and second).
(Three devices are occupied.)
16-bit binary
Specifies "hour" of the time data (hour, minute, and second).
(Three devices are occupied.)
16-bit binary
