Configuration of the Amplifier over EtherNet/IP
EMGZ321._.EIP may, but need not be configured via EtherNet/IP. The Amplifier can
be configured by means of a controller. It is integrated in 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 manual
of the respective controller.
There are three possibilities to configure the EMGZ321._.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
EMGZ321 must be used.
How the messages are used, is described in shows the example program.
The example project EMGZ321_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.
