mdrSend
This function writes devices in a batch.
■ Format
short mdrSend(long lPath, short sRoute, long lNetNo, long lIoNo, long lStNo, short sCPU, long lDevType, long lDevNo, long*
plSize, short* psData)
■ Argument
Argument
lPath
sRoute
lNetNo

sCPU
lDevType
lDevNo
plSize
psData
■ Description
• This function writes data for the size specified to the write data size (plSize) starting from a device, which is specified to the
device type (lDevType) and the start device number (lDevNo), of a module specified to the network number (lNetNo), the
start I/O number (lIoNo), the station number (lStNo), and the CPU number (sCPU).
• 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).

Page 108 ERROR CODE LIST
Description
Specify the path of the opened channel.
Specify the access route to target module.
• 0: CC-Link IE Controller Network
• 1: CC-Link IE Field Network
• 2: MELSECNET/H
• 3: CC-Link
• 4: Bus interface
Specify the network number of target module.
Page 14 Argument specification
Specify the start I/O number divided by 16 of the target module.
Page 14 Argument specification
Specify the station number of target module.
Page 14 Argument specification
Specify the target CPU number.
• 0: Control CPU specification
• 1 to 4: Multiple CPU 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 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.)
