unsigned long ulBufSize)
Argument
Argument Name
usIoNo Module position
ulOffset Offset
ulSize Data size
pusDataBuf Data storage destination
ulBufSize Data storage destination size
Description
• This function writes data in the data storage destination (pusDataBuf) for the size specified to the data size (ulSize) to the
fixed cycle communication area of a CPU module specified to the module position (usIoNo). Data is written by specifying an
offset address from the start of the fixed cycle communication area to the offset (ulOffset).
• The fixed cycle communication area can be accessed only when the fixed cycle communication area setting under the
multiple CPU setting is configured.
• When executing this function while the operating status of a CPU module is not RUN, the STOP/PAUSE error (-28640)
occurs.
