the same network. The communication between machine control and amplifier is
carried out with dedicated software (e.g. RSLogix5000 from Rockwell). Please
refer to the operating manual of the controller.
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 selected then messages from the PLC to
the EMGZ309 must be used.
How the messages are used is described in the example project.
The example project EMGZ309_EIP_Example_Project_Vx.xx is available for
download on the FMS website.
Note
The configuration of the amplifier via EtherNet/IP must be used as commissioning
procedure. Continuously writing parameters on a cyclic base is not allowed and
will lead to communication problems and reduced the lifetime of the device.
5.5
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.

Integration in an Allen-Bradley PLC
Following chapters deal with the integration and operation of the EMGZ309._.EIP
amplifier with an Allen-Bradley PLC. The project software RSLogix5000 from Allen-
Bradley is required to program the PLC. Furthermore, it is assumed that a
development system with PC and corresponding development software RSLogix
from Rockwell Automation is available and the programmer is familiar with these
tools..
6.1
Hardware Environment
The EMGZ309._.EIP must be connected to an Ethernet switch which in turn is in
the same network as the PLC. Only in this way a communication between
amplifier and PLC can take place. Several EMGZ309._.EIP amplifiers or other
ErtherNet/IP devices can be connected to the same network.
