Two Fronius connected to CCGX by modbus-TCP. Both inverters show good data in CCGX in real-time. One Fronius has the datamanager (master), the other is light version (slave). All connections are to the same switch on Ethernet.
On VRM one inverter shows disconnected.
It says this "old data", but the numbers are accurate and reported in real time. Not sure what the NaN is about...
