            Description

            According to profinet specification, if the Device receives multiple alarm indications simultaneously the AR shall be aborted with Error "AR protocol violation" and may acknowledge the fist alarm indication. Currently, the IO Device sends immediately valid transport acknowledges (ACK-RTA) and alarm acknowledge (DATA-ACK) with wrong SendSeqNum and AckSeqNum to the fist received alarm. This Issue can be reproduced using ALPMR3 testcase of PNIO RT Tester.
