Configuration of the Amplifier over EtherNet/IP
EMGZ309._.EIP may, but need not be configured via EtherNet/IP. The Amplifier can
be configured by means of a machine control unit, provided this unit is integrated in
the same network. The communication between machine control and amplifier is
carried out with dedicated software (e.g. RSLogix5000 from Rockwell). How exactly
this is done, it can be found in the operation manual of the respective controller.
As mentioned earlier there are three possibilities to configure the EMGZ309._.EIP. If
the method over EtherNet/IP is used, the other two options (operation panel or web
interface) are still possible but not meaningful. The EtherNet/IP method has then
always priority and overwrites any other configurations set by the other two
methods. If the configuration over EtherNet/IP is preferred, there are two different
ways of doing it:
1.
Initialisation of all parameters at connection establishment with controller.
2.
Configuration of individual parameters as needed
The Bit cfgApplyConfAsmData determines which of these two methods will be used
(see EDS-file). If the Bit is set, the first method will be applied and the controller will
initialise the amplifier at each connection. If the Bit is not set, all parameters remain
unchanged at a connection. They can then be individually programmed via
EtherNet/IP, the operation panel or the web interface.

Calibration over EtherNet/IP
Usually the calibration procedure for amplifier and load cells is carried out at the
commissioning of the machine. The two commands
Offset
and
Calibration
are
available for the calibration of the amplifier over EtherNet/IP. From case to case it is
to consider whether a calibration via web interface or operation panel is more
favourable. With difficult accessibility of the amplifier it might make sense to do the
calibration over EtherNet/IP.
