■ Description
• This function writes data to a device, which is specified to the randomly selected device (plDev), of a module specified to
the network number (lNetNo), the start I/O number (lIoNo), the station number (lStNo), and the CPU number (sCPU).
• The data to be written is stored to the write data storage destination (psBuf) in word units. A bit device and a word device
are stored per 1 point, and a double-word device is stored in word units.
• Specify so that the total number of write points specified for each block is 10240 points or less. Otherwise, a size error (-5)
will occur.
• Note that the extension comment information will be deleted when the data is written to the block to which an extension
comment is assigned (extension file register).
• Also, note that sub 2 or sub 3 program will be deleted when data is written to a block (extension file register) overlapping
with the program setting area for sub 2 or sub 3.
• When '0' is specified to the label code (ullLbCode), the device is written without checking the label code.
■ Example
The following tables show the examples of values specified to the randomly selected device (plDev) and the write data
storage destination (psBuf), and the number of bytes of write data.
