unsigned long ulBufSize)
Argument
Argument Name
usIoNo Module position
ulOffset Offset
ulSize Data size
pusDataBuf Data storage destination
ulBufSize Data storage destination size
Description
• Writes data of the data storage destination (pusDataBuf) of the data size (ulSize) to the address moved by the amount of
the offset (ulOffset) from the start of the buffer memory.
• When "0" was specified for the data size (ulSize), a memory size specification error occurs.
• If this function is executed when the operating status of the MELIPC is not RUN, a STOP error occurs.
