Once again, thank you so much for your help!
There seems to be some problems when I want to "Set" the Ramp/soak. (or load it to the PID)
This is the error message:
"version = 0.8.0
1 18:27:16.883 Modbus Error: writeSingleRegister() CRC error: 0 ('\x00\x00') instead of 42571 ('\xa6K'). The response is: '\x12\x06\x047\x00\x00'@line 20309"
And should this be checked out?

The magic "Modbus Port" flag connects the Fuji device implementation to the separate MODBUS implementation (realized via a Python Modbus lib) also used by the MODBUS meter device. If ticked the serial port has to be configured via the MODBUS tab in the serial dialog and not the first tab. Without this flag ticked, the Fuji device implementation uses its own native MODBUS implementation. However, both variants should work (and are reported to work for others). Could it be that your Fuji is in some kind of read-only mode?

Thanks. It may be that the checked python lib is adding an extra padd zero digit (three instead of two) causing an exception in the CRC return function. two digits = 1 byte1 18:27:16.883 Modbus Error: writeSingleRegister() CRC error: 0 ('\x00\x00') instead of 42571 ('\xa6K').

try it unchecked. artisan has also its own CRC function (not from a lib). if you uncheck it, it won't use the above lib.And should this be checked out?
Good luck
