M20 (hours) = ON
M21 (hours) = ON

When M12 = ON, then M20, M21, or M22 is set to ON.
The TCMP instruction is not executed when M12 switches from ON to OFF, and
M20 to M22 remain in the state prior to M12 = OFF. Use the RST or ZRST
instruction to clear the comparison result of M20 to M22.
Connect M20 to M22 in serial or parallel mode to acquire the ≥, ≤, and ≠ results.
TZCP: Clock data range comparison
◆
Overview
The TZCP instruction compares the time of an internal real-time clock with a specied time range. The
result is stored in three consecutive variable units.

S1 Lower limit
Lower limit of a time range, which is represented by
hours, minutes, and seconds respectively stored in three
