Generator warm-up / cool-down menu disappeared, came back, gone again

Q&A and troubleshooting

Hello, I have a DSE4620 controlled genset wired via MODBUS to my 3-phase 3x5kW Multiplus II system for my off grid home. I have my Cerbo on 3.52 and the Multiplusses are on 552. Everything works (MODBUS comms between DSE4620 genset and Cerbo), however, some menu options magically disappear and reappear, for example the cooling down and warm up settings on the genset. Same for the multiplus generator current limit quick menu in VRM. Sometimes I have the option to set it, sometimes I cannot see this. Very strange… Anyone has any thoughts on this? Thanks.

PS: I have another Cerbo used to control the UPS (Victron Easysolar) on 1 phase, and the option there also disappeared. And my installation at home suddenly also misseds this option… Is it VRM related?

Have you looked for error messages in the menu / services / Modbus TCP … Perhaps an error log with the necessary register etc.?

No errors. Besides, when disabling Modbus comms to the DSE Genset, and using the genset as a classic generator with relay activation, this warm-up / cool down menu is also not available anymore. So I am sure it has nothing to do with the Modbus;
