SetOutput

Set a digital output to ON or OFF for the main board or a DIO option card.

int SetOutput(int bd, int out, bool on);

Parameters

• bd - 0 for main board or number of digital output card.
• out - output number 1-4 main board, 1-8 DIO option card.
• on - true = turn output on, false = turn output off

Return Value

• Returns the result - OK success

Remarks

The main board or option card must already be opened by calling OpenMnBd first. The call does a wait for acknowledgement. If the application is using main board communication events these events may be called during the wait for acknowledgement.

Examples

if(SetOutput(MNBD_DEV, 1, true) == OK)
    DisplayText(0, 0, "Output 1 is ON");

if(SetOutput(1, 4, false) == OK)
    DisplayText(0, 0, "Card 1 Output 4 is now OFF");
