If the iq_xAction input becomes True and the CMD and StartStep in StandardModuleInterface are 0, the iq_diCMD and iq_diStartStep inputs are copied into the corresponding variables of StandardModuleInterface and iq_xAction is set to FALSE.
An alternative verification is made if the iq_xAction and iq_xOverwrite inputs are activated. Whether or not the iq_diCMD or iq_diStartStep inputs are equal to the corresponding variables in StandardModuleInterface is checked. If the condition is fulfilled, then the iq_diCMD and iq_diStartStep inputs are copied into the corresponding variables of StandardModuleInterface and iq_xAction is set to FALSE.
