Siemens AG 2017 All rights reserved 1 Introduction 1 Introduction 1.1 Overview Since the publication of TIA Portal V14 you can directly read out alarms from the alarm server of the S7-1500 PLC using the "" instruction. These alarms can be sent to higher-level alarm system (e.g. PC, PLC). 1.2 Mode of operation The incoming and outgoing alarms of the S7-1500 PLC_1 are read out and acquired and saved in a "alarmstorage" data block in PLC_1. Afterwards you can send these alarms from PLC_1 with the "TSEND_C" instruction as string to PLC_2. The alarms are received on the PLC_2 with the "TRCV_C" instruction and stored in a "rcvdstorage" data block. The alarms received via "" can be read out via OPC UA Client.
