| 1 : Channel used for digital |
| output |
data[0] memory on/off
Activates and deactivates the digital output memory.

+----------------------------------------------------------------------------+
| Task : Sets or resets the output witch has been passed with the |

| an ouput high. |
+----------------------------------------------------------------------------+
| Input Parameters : unsigned char_ b_BoardHandle : Handle of board APCI-1710 |
| unsigned char_ b_ModulNbr (aref ) : Selected module number (0 to 3)|
| unsigned char_ b_OutputChannel (CR_CHAN) : Selection from digital output |
| channel (0 to 2) |
| 0 : Channel H |
| 1 : Channel A |
| 2 : Channel B |
+----------------------------------------------------------------------------+
| Output Parameters : - |
+----------------------------------------------------------------------------+
| Return Value : 0: No error |
| -1: The handle parameter of the board is wrong |
| -2: The module parameter is wrong |
| -3: The module is not a digital I/O module |
| -4: The selected digital output is wrong |
| -5: digital I/O not initialised see function |
| " i_APCI1710_InitDigitalIO" |
| -6: The digital channel A is used for input |
