Show Thermal Time on REM620 Display
The problem I'm facing is, the REM620 (Protection Relay for motor) has a thermal trip, and if it trips it can only be reset once the thermal trip time is passed.
I'm trying to display the time variable on the front display of relay, so that we can know how much time is left to reset the relay. I can not find the time variable in existing parameters list that can be displayed on relay.
I'm using PCM600 for configuration.

I think it isn't possible to map the remaining time of the thermal blocking to the single line diagram of REM620. You can map the Thermal Level indicator, which tells the approximation how far the thermal level is from the operate values. Thermal level can be added as a Measurand and can be found in MPTTR1.Therm-Lev.
On Thermal Level 1,00 is the operate level.
Please also note, that the remaining time is always available in the Monitoring menu of the relay.
I have taken the feedback on showing the remaining time on SLD and forwarded it to the respective Product Manager for future consideration.
