Operate Crosspoint
Description
Operate a single matrix crosspoint.
Prototype
DWORD PIPLX_OpCrosspoint(SESSION session, DWORD CardNum, DWORD OutSub, DWORD Row, DWORD Column, BOOL Action);
Parameters:
Session - The session variable obtained from the PICMLX_Connect call
CardNum - card number
OutSub - output sub-unit number
Row - crosspoint row (Y) location
Column - crosspoint column (X) location
Action - 1 to energise, 0 to de-energise
Returns:
Zero for success, or non-zero error code.
Note
This function supports matrix operation using row/column co-ordinates in place of the linearized bit-number method employed by PIPLX_OpBit. It offers more straightforward matrix operation, and avoids the need for re-coding if a matrix card is replaced by one having different dimensions.
