Dear all,
I am quite confused of several options for developing alarms in PLCnext Engineer and which one should I use.
On one hand, there is „Alarms“ library from the store. It’s a good option to show simple alarms in the HMI. However it’s not possible to register alarms in OPC-UA, or to acknowledge or confirm alarms…
On the other hand, there is the alarm function blocks integrated in the PLCnext Controller>Alarming functions. In the documentation it seems the main functions for developing alarm systems. They allow to register alarms in the OPC-UA server, to acknowledge or confirm alarms. Everything is made via function blocks, I haven’t found anything prebuild to use in HMI.
Finally we can use new Alarm server integrated in PLCnext Engineer from version 2024.0.2. You have to configure everything via PLCnext Engineer. As far as I know it’s not possible to register alarms in the OPC-UA server.
At this point I’m confused of which option should we use for developing alarms. We need OPC-UA alarms but also HMI and PLC functions to acknowledge and confirm.
Thank you
