For the index addresses and subindex addresses of Delta servo and AC motor drive, refer to the explanation of the

COPRW instruction. In principle, the parameter values of Delta servo and AC motor drive are both16-bit or 32-bit

values including floating point numbers. If you need write an 8-bit value, use the COPRW instruction.

D is the communication completion flag. D will turn on after the sending of multiple communication messages is

See the detailed sending process and sequence diagram below.

 The COPWL instruction is enabled and starts to send data.

 After the COPWL instruction sends one piece of message, the next PLC instruction continues to execute.

 As the COPWL instruction is scanned once again and the prior message has been received by the slave, the

COPWL instruction sends the next message.

 When the last written-data sending is done, the instruction will set the completion flag to ON.

 When the completion flag turns on, the COPWL instruction need be disabled by manual so that the subsequent

COPWL or COPRW instruction can continue to work.

Note: When you disable the instruction, the completion flag will be automatically cleared accordingly.

Note: The sequence diagram above shows the sending of 3 pieces of written data.

After the instruction is enabled, wait until the writing is complete and then disable the instruction. If there is a

communication error in the execution, shoot the trouble and then re-enable the instruction to write all data.
