Hello,
We try the adress registers for a Sistema Airpack Home ventilation device with RS485. connected the Modbus to server, added all the read input registers and Holding registers, an those errors starts to appear. if i set one who is in error to not read cyclically, the error take the next adress. if i set all the error to not read cyclicaly, the errors stop appear. I just want to see what i need from those adresses, and to use them
also, we have a second device on modbus, but we didn't had any problem with that

Exact model or modbus registers table? I would suggest to start with just one easy register(temperature, or mode control). Make it work first and then move on to next register. I couldn't find any useful info with "Sistema Airpack Home ventilation"
Local-Modbus.bos Start with temperatures - if you get these values to work move on to other registers that you need.

Same problem. it's appear on Slave, communication error -> True
Then it could be a driver or cabling problem too. Try to roll back the driver - I've had problem with windows update after it my RTU connections all had com errors. Re-check the polarity. Also try different data settings:
Or make a ticket and maybe the support can take a look at it. But you should get the communication error to false before you can add registers.
Hey
Are you making a template for a new device? Seems like there are more problems on the modbus line. Would be good to have some info on the device itself.
OT: If you use usb dongle. Also try to rollback the driver. I have seen problems with the new driver that windows updates. The communication error stays on True then and all you get is no response.
