CCPU_ReadLinkDevice_ISR
Reads data from link devices of CC-Link IE Field Network.
Format
short CCPU_ReadLinkDevice_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
This function reads data in a device after one specified to the device type (sDevType) and the start device number (ulDevNo)
for the size specified to the data size (ulSize), and stores it in the data storage destination (pusDataBuf).
Precautions
Note that the size of data storage destination (ulBufSize) should be equal to or bigger than the data size (ulSize).
Do not execute this function in a routine other than an interrupt routine.
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.
Assure a read data area of the read word count.
Do not specify a device outside of the range.
