ReadOutputBit

Reads a bit from an output of a real or simulated I/O module.

Syntax

KsError ReadOutputBit(
     int Index,
     int BitOffset,
     BOOL* Value
);

Parameters

Index: the index of an I/O module. Indexes are zero based. Aliases affect this parameter.

BitOffset: specifies a bit offset to the location to read a bit value. The max offset is determined by OutputLength in the SlaveStatus structure.

Value: pointer to the value that will receive the bit read.

Return value

If the function succeeds, it returns errNoError, otherwise an error code. For more information about the error code, see the KsError list.

Remarks

ReadOutputBit can only be called once a link is established and started.

BOOL boolWrite = 0;
