mpiSqNodeDigitalIn
Declaration
long mpiSqNodeDigitalIn(MPISqNode node, long bitStart, long bitCount,
unsigned long *state );
Required Header: stdmpi.h
Change History: Added in the 03.02.00
Description
mpiSqNodeDigitalIn gets the current state of multiple digital inputs on the specified SynqNet node.
| node | a handle to a SynqNet node object. |
|---|---|
| bitStart | the first bit. |
| bitCount | the number of bits to be read. |
| *state | a pointer to where the current state of the input bits is written to by this function. |
| Return Values | |
|---|---|
| MPIMessageOK | |
Sample Code
The following MPI code will get the current state of digital inputs 3, 4, and 5 of Node 0 (in the example network these bits spread over segments 0 and 1):
long x;
mpiSqNodeDigitalIn( sqNode0, 3, 3, &x );
