1. Enter "24", the PW command No., in the data memory
corresponding to the PLC Command Address (DM100 in this

switching to program No. "23" on "SD1".
* The address to use is 1 word for Command No. and 2 words
for other parameters.
2. Enter 1 in the data memory corresponding to the PLC
Command Execution Address (bit) (DM002 in this example).

3. The command is executed.
4. Check if the values of the data memory corresponding to
the PLC Command Complete Address (bit) and Command
Result Address (DM003 and DM200 respectively in this
example) have changed.
When the command is successful: CV‐X writes "1" into Command
Complete Address (bit), and "0" into Command Result Address.
When the command fails: CV‐X writes "1" into Command
Complete Address (bit), and an error code into Command Result
