DO_GetSafeValues
This function code is used to get the output safe values of
contiguous D/O channels.
C/C++
Arguments
Return Value
int DO_GetSafeValues ( int hConnection,
BYTE bytSlot,
BYTE bytStartChannel,
BYTE bytCount,
DWORD * dwValue);
hConnection: The handle for an I/O connection.
bytSlot: Slot number of the I/O module, from 1 to 32.
This parameter is inactive for the ioLogik
E2000 and R2000.
bytStartChannel: Specifies the starting channel.
bytCount: The number of channels to read.
dwValue: A pointer to the safe values of the contiguous
D/O channels; each bit holds the value of one
channel. A bit value of 0 represents the digital
output status of the start channel. A bit value of
1 represents the status of the second digital
output channel. The values of the unused bits
are random.
