Hello,
SL has not been responding to modbus messages for a few days now. In the installation there are 4 Energy meter EM112 and a heat pump, for each of them I get the following error: "device1 (RTU 1 slave xx) read failed: Operation timed out"
This installation was working perfertly 3 years, but from one day at 00:00. All the devices stop their comunications. I review the cable (A, B and Ground) and final resitances, they are in right ohm. Also modbus message parameters on every device (baud rate, parity... ) was checked.
Also, I tried to increase timeout, and comunicate directly to a well know coil by tool "Read test" and lua script, with no luck.
Any help or hints would be welcome.
Regards,
