Hello, how are you? We are developing an SOE application for synchronous motors that requires IEC-61850 communication with the SEL Axion 2240 PLC and cMT3108XP HMI. We were able to import the TAG map into EB-pro and establish communication, however, we are unable to display the time in milliseconds with the “Event Display” object.
The milliseconds issue is the heart of 61850 communication, and we can’t display them? Is there a way to create an event list that can provide milliseconds?
Our HMIs do not record alarms down to the millisecond. We recommend configuring the alarm logic in the PLC, provided it is capable of recording events with millisecond precision, and then transferring that value to the HMI. The millisecond value can also be saved as an alarm using the Event Alarm Log and Multi-Watch features. Please ensure that the watch address is correctly mapped to the PLC address and that the syntax used to display the message is accurate.
Hi Aaron, thanks for the quick reply! I looked at the demo application, and the multi-watch feature does indeed seem like the way to achieve what I need. I haven’t tested this feature connected to the PLC yet. I plan to do so this week. As soon as I’m able to make progress with the tests, I’ll come back here to update the thread with screenshots. I believe this is a topic that’s not often explored in the community.
