mdSendEx
This function writes devices in a batch.
Format
long mdSendEx(long lPath, long lNetNo, long lStNo, long lDevType, long lDevNo, long* plSize, short* psData)
Argument
Argument Name
lPath Path of channel
lNetNo Network number
lStNo Station number
lDevType Device type
lDevNo Start device number
plSize Write data size
psData Write data storage destination
Description
• This function writes data for the size specified to the write data size (plSize) from a device specified to the device type
(lDevType) and the start device number (lDevNo) of a module specified to the network number (lNetNo) and the station
number (lStNo).
• 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, a writable size is returned to the write data size (plSize).
• 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).

Specify the station number of target module.
Page 44 Argument specification
Specify the device type for device to be written in batch.
Specify the start device number to be written in batch.
(For a bit device, set a device number in multiples of 8).
Specify the write data size in byte units.
(Specify the value in multiples of 4 when a double-word device (LZ, LTN, LCN, LSTN) is
specified, or specify the value in multiples of 2 when a word device or bit device is
specified. If the value other than that is specified, the size error (-5) will occur.)
Specify the storage destination (address) of write data.
Reserve a continuous area for the write data storage destination.
