Explanation
1. This instruction writes data into the file register. The description of the operands is as follows.
•
S: The initial address of the data source; it is suggested that you declare an array type variable.
•
D: The initial address where the instruction stores data. It is suggested that you assign an address for the file
register and declare an array type variable.
•
n: The length of the data that the instruction writes into the file register, between 1–2048. If the value
exceeds the range, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B.
•
If the device S or D exceeds the allowed range, SM0 is ON, and the error code in SR0 is 16#2003.
2. Since it takes 60–120 ms for the instruction to write the data, it is suggested that you use this instruction when the
PLC is idle. For example, when there is no external interrupt task, no high-speed output, or any immediate events
for the PLC to process.
3. The instruction writes only when the contact switches from OFF to ON and writes only once.
NOTE: You can write into this file register a maximum of 100,000 times.
