F_iecSetAOQuality

Syntax

FUNCTION F_iecSetAOQuality: UDINT
VAR_INPUT
    QMsk    : DWORD; 
END_VAR
VAR_IN_OUT
    dbEntry : ST_IEC870_5_101AODBEntry;
    device  : ST_IEC870_5_101DeviceInterface;
END_VAR

Inputs

QMsk: Quality flags. The quality flags can be combined with OR links. If QMsk = null no flags are set/reset. A list of available quality flags can be found here: Quality flags.

Inputs/outputs

dbEntry: Application object whose quality flag status is to be set.

device: Communication interface of the IEC device.
