6.10 Set Self-Test Period diagiq
Syntax
diagiq(period)
period: Self-test period (in tenths of a second).
The system cyclically reads the internal status of the cards connected to the serial bus (%I, %Q) and refreshes
diagnostic word %Irc3C.W.
The default period is 400 milliseconds.
Function diagiq() is used to inhibit the self-test or modify the default period. The period parameter must be ZERO to
inhibit the self-test or between 1 (0.1 second) and 10 (1 second). It should be noted that a short period involves an
extra workload for the CPU.
diagiq() must be called in task %INI.
