2.3 System Description EMGZ309
The digital tension measuring amplifiers EMGZ309 are suitable for tension
measurement with all FMS force sensors. The amplifier can handle 1 or 2 force
sensors. Three different analogue output modes can be selected (0…20mA,
4…20mA or 0…10 VDC). As a plug & play unit the setup through the operating panel
is straightforward and quickly accomplished. Alternatively, more advanced users
can access all the internal parameters through a laptop or local PC via a web
browser. That allows a fine tuning of the amplifier even to the most demanding
system requirements.

2.4 System Description EMGZ309._.EIP
The amplifier EMGZ321._.EIP offers in addition to his standard features the
possibility to be used as an EtherNet/IP device in a corresponding network.
EtherNet/IP bases on the Ethernet TCP/IP and the UDP technology as well as on the
CIP (Common Industrial Protocol). The amplifier can be embedded in a standard
Ethernet infrastructure. Its fast data rate with cycle times down to 2ms makes the
device ideal for applications in automated assembly and production lines. It allows
the measurement of web tension and its transmission over Ethernet to a controller
in real time. Configuration of the amplifier takes place either over the EtherNet/IP, a
web browser or over the operating panel.

3.4 Mounting the Force Sensors
Mounting of the force sensors is done according to the FMS Installation manual
which is delivered together with the force sensors.
3.5 Wiring the Amplifier
One or two force sensors can be connected to the measuring amplifier. When using
two force sensors, the sensors are internally connected in parallel. The output
signal of the measuring amplifier will then correspond to the average value of the
two sensors. The connection between force sensors and measuring amplifier has to
be done using a 2x2x0.25mm2[AWG 23] shielded twisted-pair cable

chapter 4.8).
4.5 Offset Compensation
With the Offset Compensation you can compensate the roller weight. It is always
performed before the calibration. The Force Measuring Sensor should not be loaded
while the Offset Compensation is being done. There are two possible ways
performing the offset compensation.
A) Offset compensation over the operating panel (see chapter 4.5)
B) Offset compensation via EtherNet or a Web Browser.
For this method proceed to chapter 9.1 (Fig. 23).

4.7 Calibration
By calibrating (setting the Gain), amplifier and
load cells are adjust so that the display gives
the actual tension value. There are two
methods of calibrating the system. The first
method uses a defined weight (see Fig. 7). This
method is the preferred one since it delivers
the most accurate results. The second method
is based on a calculation method in
conjunction with the FMS Calculator. This
Calculator can be down loaded from the FMS
web page. Please consult the factory for this
option.
Note
If the Device Mode is set to [VoltGaug], the force corresponding to the calibration
weight must be input in Volt (V) in the following calibration procedure. The
parameters System Force [SysForce] and Force at maximum output [F@OutMax]
won’t be requested (see also chapter 9.3, section B).

4.9 Analytic Calibration Method
Determining the gain by means of the FMS-calculator:
This method is used when the traditional calibration method with a weight is
difficult or impossible at all due to machine accessibility, weight adequateness etc.
This calculation method requires the FMS-calculator V2.1 or higher.
If necessary download and install FMS-calculator from the FMS homepage at:
http://www.fms-technology.com/en/technical-information.php
Gain-calculation-tool
The gain calculator is an optional feature of the FMS-calculator. It delivers the gain
factor for easy weightless calibration of FMS amplifiers.
1. First, the application related parameters must be entered in the FMS-calculator
e.g. min./max. force values, wrap angle and other sensor specifications. Follow
the instructions of the FMS-calculator manual.
2. Choose the appropriate sensor type.
3. If the sensor evaluation is correct, the gain calculation tool can be started with a
click on the corresponding symbol. The date will be taken over from the previous
input (field (1) Fig. 9). The gain calculation tool will only start-up, if all data have
been entered and the appropriate sensor defined.
4. Choose the amplifier type (field (2) Fig. 9).
5. The calculated gain factor is available in field (3) (see Fig. 9)

5Network Connection over EtherNet/IP
The amplifier EMGZ309._.EIP is able to communicate with other devices over an
Ethernet network. CIP (Common Industrial Protocol) is used as the protocol for the
data link. The amplifier acts as a so called “Producer”and the machine control (or
PLC) as the “Consumer”.
5.1 EtherNet/IP Specification:
Physical layer: Ethernet IEEE 802.3.
Transport protocol: TCP/IP und UDP
Standard: CIP IEC 61158
Conformity: CPF 2 (Communication Profile Family 2) IEC 61784-1
5.2 Amplifier Functionality over EtherNet/IP
Basically all functions for configuration and calibration can be performed over
EtherNet/IP. Furthermore, the measured tension values are cyclically propagated
over the network and made available to the Consumer (PLC).
5.3 Integration of EMGZ309._.EIP in an Ethernet Network
In order to integrate the amplifier in an Ethernet network and enable data transfer
over it following conditions must be fulfilled:
✔An EMGZ309 amplifier with the option EtherNet/IP (EIP) must be used.
✔The IP-Address must be assigned in the fix address block and must be
unambiguously. It may only exist once in the network.
✔The network mask must correspond with the used device configuration.
If these prerequisites are given, the controller will recognise the amplifier as an
EtherNet/IP device in the network and be able to communicate with it. The interface
information for EMGZ309._.EIP is defined in an EDS-file.
EDS-files for EMGZ309._.EIP can be downloaded from the FMS webpage.
Link: http://www.fms-technology.com/en/eds-files.php

Operating Manual EMGZ309._.EIP
17
5.4 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.
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.

Operating Manual EMGZ309._.EIP

6Integration 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.
.
6.2 IP Configuration
In an industrial environment the IP addresses are normally assigned fix to the EIP
devices. This holds also for the EMGZ309._.EIP amplifier that needs a fix IP address
in the network. The IP address configuration must take place before the amplifier is
integrated in a network. This is done over the operation panel or over the web
interface.
The procedures are described in the state diagrams chapter 8 (Fig. 18; 19) and
chapter 9 (Fig.31)
6.3 Integration in a Project
Before starting the development system RSLogix5000 the PLC and amplifier need
to be connected to the network and powered-up. Now a new project or an existing
project can be opened in RSLogix5000. Search in the tree structure Controller
Organizer for the listing Ethernet and make a right mouse click (see Fig. 10).

Operating Manual EMGZ309._.EIP
19
In this example CompactLogixL23E-QB1B is used. If a different hardware is used,
one may find the listing Ethernet in another place.However, the principal approach
is always the same. After a right mouse click on Ethernet a dialog window will open
up. Left mouse click on New Module...and a new window will open up (see Fig.11).
