Writes data to the buffer memory of a remote device station on CC-Link IE Field Network.
Format
long mdRemBufWriteEx(long lPath, long lNetNo, long lStNo, long lOffset, long* plSize, short* psData)
Argument
Argument Name
lPath Path of channel
lNetNo Network number
lStNo Station number
lOffset Offset
plSize Write byte size
psData Write data
Description
• Writes data to the buffer memory of a remote device station on CC-Link IE Field Network specified by the network number
(lNetNo) and station number (lStNo).
• If a value outside the range or an odd number is specified for the write byte size (plSize), '0 is stored as the write byte size
(plSize) value.
• Make sure that the write target range does not exceed the buffer memory range of the remote device station. When the
buffer memory range is exceeded, a timeout error may occur or the remote device station may no longer operate normally.
For details on the range of the buffer memory of remote device stations, refer to the manual of each remote device station.
• Data can be written only to the buffer memory of a remote device station on CC-Link IE Field Network by this function. Data
cannot be written to the buffer memory of an intelligent function module controlled by a head module on CC-Link IE Field
Network.
• To write data to the buffer memory of an intelligent function module that is controlled by a head module on CC-Link IE Field
Network, apply the mdSendEx/mdSend function.
