Instruction code

Explanation:

S: The device into which the setting value is written

The operand S occupies seven consecutive devices.

When users want to adjust the built-in real-time clock in the CPU module, they can use the

instruction to write the correct current time into the built-in real-time clock.

When the instruction is executed, the new setting time is instantly written into the real-time

clock in the PLC. Therefore, when the instruction is executed, users have to make sure that

the new setting time is consistent with the time when the new setting time is written into the

real-time clock.

When M0 is ON, the correct current time is written into the built-in real-time clock in the PLC.

General data

Additional remark:

If the value in S exceeds the range, the operation error occurs, the instruction is not executed,

SM is ON, and the error code in SR is 16#2003.

If S+6 exceeds the device range, the operation error occurs, the instruction is not executed,

SM is ON, and the error code in SR is 16#2003.

If users declare the operand S in ISPSoft, the data type will be ARRAY [7] of WORD/INT.
