Description
• Writes data to the module specified by the network number (lNetNo) and the station number (lStNo).
• Writes data in the size specified for the write data size (plSize) to the start of the device specified by the device type
(lDevType) and the start device number (lDevNo).
• It checks the arguments and verifies whether the address + size determined by the arguments is within the device memory
range.
• When the write data size exceeds the device range, the writable device size (the maximum value that can be specified for
the write data size (plSize) when '0' was specified for the start device number (lDevNo)) is returned to the write data size
(plSize).
• Note that the extension comment information is deleted when the data is written to the block to which an extension
comment is assigned (extension file register).

Specify the device type for device to be written in batch.
Specify the start device number to be written in batch.
(For bit devices, specify the device number in multiples of 8.)
Specify the write data size in byte units.
(Specifies the value in multiples of 4 when a double-word device (LZ, LTN,
LCN, LSTN) is specified and specifies the value in multiples of 2 when a
word device or bit device is specified. If other values are specified, a size
error occurs. )
