Brief Description; Scope Of Delivery; Technical Data; Block Diagram - Camille Bauer EMMOD206 Mode D'emploi

1. Brief description

The extension module EMMOD206 supplements the func-
tionality and flexibility of the basic device A2xx and allows
reading instantaneous values and metering contents via M-
Bus interface. In addition a digital input is provided to syn-
chronize the intervals for the mean-values calculation or to
switch the tariff of the energy meters.
The selection of the measurements to transfer and further
settings can be performed via the keys of the basic unit. The
interface can be temporarily switched from M-Bus protocol
to Modbus protocol to allow a comfortable configuration of
the measurement functionality of the basic device A2xx by
means of the A200plus software.
The module can be retrofitted without tampering with the
basic unit. But to do so, the basic units A210, A220, A230
and A230s must be equipped with firmware version V5.0 or
higher.
