CCPU_WriteLinkDevice
This function writes data to the own station link devices of the following modules: CC-Link IE Controller Network module, CC-
Link IE Field Network module, Ethernet module (when CC-Link IE Field Network is selected), MELSECNET/H network
module, and CC-Link IE TSN module which are controlled by a C Controller module.
Format
short CCPU_WriteLinkDevice (unsigned short usIoNo, short sDevType, unsigned long ulDevNo, unsigned long ulSize,
unsigned short* pusDataBuf, unsigned long ulBufSize)
Argument
Argument Name
usIoNo Module position
sDevType Device type
ulDevNo Start device number
ulSize Data size
pusDataBuf Data storage destination
ulBufSize Data storage destination size
Description
• This function writes data to subsequent devices after the device, which is specified in the device type (sDevType) and the
start device number (ulDevNo) of the following modules specified in the module position (usIoNo): a CC-Link IE Controller
Network module, CC-Link IE Field Network module, Ethernet module (when CC-Link IE Field Network is selected),
MELSECNET/H network module, and CC-Link IE TSN module. The function writes data in the data storage destination
(pusDataBuf) for the size specified in the data size (ulSize).
Precautions
• To access a motion module using CC-Link IE TSN, specify link devices (SB and SW). Specifying link devices other than SB
and SW will cause an error.
• To access link devices of a network module controlled by another CPU, access to another CPU via bus interface using the
MELSEC data link function.
