StartRepeatIO

Start repeating communications from the main board to report I/O status.

int StartRepeatIO(int dev, uint32 interval);

Parameters

• dev - 0 = main board I/O status, number of digital output card
• interval - update interval in milliseconds

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(StartRepeatIO(1, 200) == OK)
    DisplayText(0, 0, "I/O status five times per second");
