 Data is stored in the buffer memory area specified by (s1)+2 and (s1)+3 that is included in the station specified by (s1)+1 or to the device of the CPU

module.

 The response indicating the write completion returns from the target station to the master station.

 The device specified by (d) is turned on.

• The completion status of the G(P).RIWT instruction can be checked with the completion device (d) and the completion

status indication device (d)+1.

• Completion device (d)

This device turns on during END processing of the scan where the G(P).RIWT instruction completes, and turns off during the next END processing.

• Completion status indication device (d)+1

This device turns on or off depending on the completion status of the G(P).RIWT instruction.

When completed successfully: The device remains off.

When completed with an error: The device turns on during END processing of the scan where the G(P).RIWT instruction completes, and turns off during the

next END processing.

Precautions

• The monitoring time and the number of retries can be set with the following link special registers (SWs).

• Monitoring time setting (SW0009)

• Setting of the number of retries for dedicated instruction (SW000B)

• The G(P).RIWT instruction can be concurrently executed from the master station for two or more local or intelligent device

stations. Two or more dedicated instructions cannot be concurrently executed for a single station. Two or more dedicated

instructions, including those other than G(P).RIWT, cannot be concurrently executed from a local station even for another

station. If the next dedicated instruction is issued before completion of the preceding one that has started, the next one will

be ignored. Create the program so that the next dedicated instruction will start after the completion device turns on,

because processing of a dedicated instruction takes several scans until its completion.
