3 Product Description
The following paragraphs contain general information on the product. Specific technical information can
be found in the datasheet.
See datasheet “ECAT STGMM 6” for further information.
3.1 Product overview
ECAT STGMM 6 is an EtherCAT-based, robust and extremely compact measurement module for strain
gauge measurements. ECAT STGMM 6 features six strain gauge inputs and offers the advantage of
being mechanically compatible to measurement modules of the CSM MiniModule series. Up to 25
measurement modules of the ECAT MiniModule series can be operated via one XCP-Gateway.
ECAT STGMM 6 is operated in an EtherCAT network as EtherCAT slave device. Configuration is carried
out via XCP-Gateway using the configuration software xx-Scan Config. The module is operated using
XCP-capable software (DAQ). ECAT STGMM measurement modules can be directly connected to a
computer if data acquisition software supporting EtherCAT master operation is used.
ECAT STGMM 6 measures the bridge excitation voltage VOUT and the differential bridge voltage VIN
using high-precision ADCs. Both values are filtered and from the filtered values, the voltage ratio
VIN/VOUT , i.e. the bridge unbalance is calculated. The measurement results can also be provided as
strain values in µm/m. Measurement results can be provided in further measurement units, if required.
Key features
Time-synchronous strain gauge inputs with measurement data rates up to 10 kHz per channel
Support of full and half bridge strain gauges with 4- and 6-wire connection
Simple configuration via xx-Scan Config using a universal measurement range
Extremely low power consumption
Very good measurement accuracy under difficult temperature ranges and environmental conditions
High resistance to interference due to ratiometric measuring principle and configurable software filter
Operating temperature: -40 °C to +85 °C
Robust aluminium housing, compatible with MiniModule series devices
Extremely compact EtherCAT measurement module, protection class IP67
Housing types
ECAT STGMM 6 is available in two housing versions: "Standard" (CL) and "Slide Case" (SCL).

1) The measurement inputs of the device in Fig. 1 are equipped with sockets of the type LEMO 1B 8-pole. There may be customer-
specific solutions regarding the sockets. All further technical specification of the measurement module, however, remain
unaffected.
2) The specification “M4 x 8 mm” only applies if a standard mounting angle from the product range of CSM MiniModule accessories
is used. In this case, the screw length may not exceed 8 mm. In case of combination with any other mounting material, a
different screw length may be required.

4 Mounting and Installation
The following paragraphs comprise important information on mounting and installing the device.
Measurement modules of the MiniModule series are robust devices, designed for being mounted in
vehicles for permanent operation. To ensure fault-free operation and a long product life, however, certain
basic requirements need to be taken into account.
4.1 Before mounting the device
ECAT STGMM 6 measurement modules are equipped with a GORE™ membrane and a venting groove.
They are essential to ensure the fault-free regulation of pressure and humidity. To ensure reliability and
performance of the device, it is absolutely essential that the small ventilation inlet it the rear side of the
housing (see Fig. 3-2) is not blocked or restricted in any way. If the ventilation inlet is blocked, conden-
sation may dam up inside the housing and cause damage to the device.
NOTICE!
The GORE membrane is needed to regulate pressure and humidity.
Do not block the ventilation inlet for the GORE™ membrane when
mounting the device.
NOTICE!
Proper functioning and electrical safety can only be ensured if the device is
correctly installed.
Make sure that the device is properly installed.
Operate the device only within the specified operation environment.
See datasheet “ECAT STGMM 6” for further information.
4.2 Mounting ECAT STGMM 6
NOTICE!
Strong magnetic fields induced e.g. by permanent magnets may impair the
proper functioning of the measurement module.
Never attach the device to a permanent magnet.
CSM offers a mounting kit for devices in standard housing.
Please contact the sales department for further details.

Preconditions
The venting groove and the ventilation inlet of the GORE™ membrane (see Fig. 3-2) are not blocked
or obstructed in any way.
The mounting location provides a firm base. Mounting the device on a soft base (e.g. sponge rubber)
may block the venting groove and cause damage to the device.
When choosing the mounting place, make sure that the ventilation hole will not be permanently
immersed in water or any other liquid.
The mounting site allows for sufficient space to connect and disconnect the cables without clamping
or pinching them.
Parts/material required
4 M4 screws 4) and a matching screwdriver
if required, further mounting material (e.g. mounting bracket)
or
4 appropriate cable ties
Mounting the device
Fix the measurement module at the mounting position using the four screws.
or
Fix the measurement module at the mounting position using the cable ties.
NOTICE!
Drilling additional holes into the housing may impair the proper functioning
of the device or even destroy it.
Do not drill any additional holes into the housing.
Mounting slide case measurement modules
If multiple measurement modules are used, slide case housings offer the advantage that not every
device needs to be mounted separately. This is of particular benefit when multiple measurement
modules are to be mounted. Further modules are simply stacked on the already mounted one. Suitable
adapter plates are available to attach different-sized slide case housings to each other. The first and the
last module of a module stack are fixed with mounting angles.
See datasheet "CSM MiniModule Accessories" for details.
4) If a standard mounting angle is from the product range of CSM MiniModule accessories is used, the screw length may not
exceed 8 mm (M4 x 8mm). In case of combination with any other mounting material, a different screw length may be required.

4.3 Installing ECAT STGMM 6
4.3.1 Before installing the device
CSM offers a wide range of cables for connecting ECAT measurement
modules.
See datasheet “CSM MiniModule Accessories” for details.
Please contact the sales department for further details.
CSM offers a calibration and repair service for ECAT STGMM 6
measurement modules.
See chapter 6.1 "Maintenance and repair".
4.3.2 Connectors
The measurement module is connected to the XCP-Gateway (alternatively to an EtherCAT master) or to
an upstream EtherCAT measurement module via the IN socket. The OUT socket is designed for daisy-
chaining the device with further EtherCAT measurement modules. EtherCAT measurement modules
receive their power supply from the XCP-Gateway, i.e. via the same cable connection
(see chapter 4.3.2.1 and 4.3.2.2). The sensors (strain gauges) are connected to the measurement inputs
1 - 6 (see chapter 4.3.2.3).
4.3.2.1 IN socket
By default, a LEMO 1B connector is used for the IN socket. To have the device equipped with a different
socket, please contact CSM.
For connecting a cable to this socket the following plug is needed: FGL.1B.308.CLLxxxxx 5).
