■Format
short CCPU_Y_In_BitEx (short sFlg, unsigned short usYNo, unsigned short* pusData)
■Argument
Argument Name
sFlg Access flag
usYNo Output signal
pusData Data storage destination
■Description
• This function reads an output signal (Y) specified to the output signal (usYNo) in bit (1-point) units.
• A read value of an output signal (Y) is stored in the data storage destination (pusData).
• This function operates to the mounted module corresponding to the specified output signal (usYNo) regardless of the type
of the parameter setting (I/O assignment). When the specified area is "empty", this function ends normally without
processing (read data: 0). When it is "input module", the I/O assignment error occurs.
• No error will occur even if this function is executed when the operating status of a CPU module is STOP or PAUSE. An
output signal (Y) is read at execution of this function.
