S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
1. 16-bit operation (TADD)
The time data (hour, minute, and second) stored in , +1, and +2 is added to the time data (hour,
minute, and second) stored in , +1, and +2, and the addition result (hour, minute, and second) is
stored in , +1, and +2.
• When the operation result exceeds 24 hours, the carry flag turns ON, and the value simply acquired by addition
subtracted by 24 hours is stored as the operation result.
• When the operation result becomes "0" (0:0:0), the zero flag turns ON.
Operand type Description Data type
Specifies "hour" of the first time data (hour, minute, and second) used in addition.
(Three devices are occupied.)
16-bit binary
Specifies "hour" of the second time data (hour, minute, and second) used in addition.
(Three devices are occupied.)
16-bit binary
Stores the addition result (hour, minute, and second) of two time data.
