CCPU_WriteLinkDevice_ISR
Writes data to link devices of CC-Link IE Field Network.
Format
short CCPU_WriteLinkDevice_ISR(unsigned short usIoNo, short sDevType, unsigned long ulDevNo, unsigned long ulSize,
unsigned short* pusDataBuf, unsigned long ulBufSize)
Argument
Argument
usIoNo
sDevType
ulDevNo
ulSize
pusDataBuf
ulBufSize
Description
Writes data in the data storage destination (pusDataBuf) for the size specified to the data size (ulSize) to the link device of
CC-Link IE Field Network after the one specified by the device type (sDevType) and the start device number (ulDevNo).
• Do not execute this function in a routine other than an interrupt routine.
• If data is written to the same device from a routine other than an interrupt routine, the output value may be
intermingled, resulting in an invalid value. Manage resources so data is not written to the same device.
Warning
• If any function to which an invalid argument is specified is executed, an error such as hardware failure (3C02H) may occur
on the MELIPC.
• This function does not check the specified arguments.
Pay attention to the following points when creating a program.
Specify the address for the write data as a multiple of 2.
Do not specify a device outside of the range.
