9.2 RS-485 interface with Modbus protocol

Modbus is an internationally widely used protocol for data transfer between devices.
All measured values, messages and parameters are stored in virtual register addresses. Data
can be read out with a read command on a register address. With a write command, data can
be written into a register address.
The register addresses of the individual measured values and parameters can be found in the
"isoxx1685Dx_D00272_00_A_XXDE" manual with the title "ISOMETER® isoxx1685Dx device fa-
mily - Modbus settings" at http://www.bender.de/manuals.
