WriteOutputBit

Writes a bit into an output of a real or simulated I/O module.

Syntax

KsError WriteOutputBit(
     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 write a bit value. The max offset is determined by OutputLength in the SlaveStatus structure.

Value: a bit value to write. TRUE writes one (1) and FALSE writes zero (0).

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

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