Function and operation explanation
1. 16-bit operation (TZCP, TZCPP)
The comparison time (hour, minute, second) of higher and lower points and the time data (hour, minute,
second) of the device specified by are compared, and the device specified by is turned ON or OFF
depending on the magnitude of difference.
Cautions
1) Number of devices occupied
Three devices are occupied each in , , and .
Be careful not to overlap with the devices used in machine control.
2) When using the time (hour, minute, second) of the clock data of the real time clock built in the PLC, first
read out the value of the special data register by using TRD, TRDP, and specify the word device in each
operand.
3) Applicable devices are limited.
S1: FX
3U, FX3UC PLCs only are applicable, index (V, Z) decoration is disabled.
S2: FX
3U, FX3UC, FX3G PLCs only are applicable.
S3: FX
3U, FX3UC PLCs only are applicable.
