Change measure-
ment method
Modbus is an international widespread protocol for exchanging data between devices.
Restart the device
Contact service All measured values, messages and parameters are dropped in virtual register addresses.
Replace device Data can be read with a read command on a register address. Data can be written in a
register address with a write command.
Replace device
The register addresses of the particular measured values and parameters can be found in
the appendix „isoxx685Dx_D00272_00_A_XXEN" with the title „ISOMETER® isoxx1685Dx
