= 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");
}}}
