NOTICE
The device must not be operated beyond its specifications.
For a detailed description of the configuration and/or sensor
operation, please refer to the full operating instructions on
our website at www.buehler-technologies.com.

5.1 Before Initial Use

The following describes the steps required on the PC for initial
sensor operation. This requires the following components:
• PC/laptop with RS232 port or alternatively USB port
serving as measuring computer
• Sensor
• Sensor cable (Item no.: 1590001001)
• Power supply incl. IEC connector (Item no.: 1590001003)
• Software "CMSensorDataViewer" and "CMSensorConfig"
• Plus for connection via USB: USB to RS232 adapter plus
driver software (Item no.: 1590001002). The software "CM-
SensorDataViewer" and "CMSensorConfig" can be down-
loaded from www.buehler-technologies.com.
Prepare the components as follows:
A) Software installation "CMSensorDataViewer"
• Extract the .zip file on your computer.
B) Install driver for the USB to RS232 adapter for data acquisi-
tion via USB (when not using an adapter, skip to step D)
• Now connect your USB to RS232 adapter to your PC/
laptop.
• If the PC does not recognise the USB to RS232 adapter, in-
stall the corresponding driver. In this case, follow the in-
stallation instructions for the operating system or the in-
cluded driver CD.
C) Connecting the sensor for data acquisition via USB
• Connect the M12 plug of the sensor cable to the sensor.
• Connect the 9pin D-sub connector of the cable to the cor-
responding serial port of the USB to RS232 adapter.
• Connect the power supply and the sensor cable.
• Now properly connect your power supply to the mains
with the IEC connector. Your sensor is now ready for use.
D) Connecting the sensor for data acquisition via RS232
• Connect the M12 plug of the sensor cable to the sensor.
• Connect the 9pin Connect the D-sub plug of the cable to
the corresponding serial port on your PC/laptop.
• Connect the power supply and the sensor cable.
• Now properly connect your power supply to the mains
with the IEC connector. Your sensor is now ready for use.
E) Start the software
• "CMSensorDataViewer" and "CMSensorConfig" can be
launched by double-clicking CMSensorDataViewer.exe or
CMSensorConfig.exe.
• Select the serial port (COM) where the sensor is connected
to the PC. When not using a USB to RS232 adapter, this is
typically COM 1.
• When using a USB to RS232 adapter, a new virtual COM
port will be added. Select this. If necessary, open the Win-
dows device manager to check the assignment of the vir-
tual COM port.

pear on the left side of the screen. The right side of the
screen can be used to show the data as a diagram.

5.2 Initial Operation

The following explains how initial sensor operation for both
the RS232 and CAN interface.
Verify the device is installed properly and safely and connec-
ted to power. The basic conditions specified in these instruc-
tions must be met to ensure proper sensor function.
5.2.1 Initial Operation With RS232 Port
After connecting the sensor to power, the sensor will auto-
matically communicate its sensor ID via RS232.
The sensor is now ready and can be read out using the analog
outputs or digital interface. For a list of supported commands,
please refer to the detailed operating instructions (download
from www.buehler-technologies.com).
5.2.2 Initial Operation With CAN Interface
The sensor comes standard with the RS232 enabled and CAN
interface disabled. To permanently enable the CAN interface,
the sensor must be configured via RS232 port (command
"WCOEN"). You can alternatively contact Bühler Technologies
GmbH Service.
On delivery, the CANopen interface of the sensor is configured
as shown in this table:
CANopen interface default configuration
Parameter Set value
Node-ID 0x64 (dec: 100)
CAN baudrate 250 kbit/s
Heart beat timer 1000 ms
Node ID + 0x180 =
TPDO1 ID
0x1E4 (dec: 484)
TPDO2 ID Node ID + 0x280 =
0x2E4 (dec: 740)
Node ID + 0x380 =
TPDO3 ID
0x3E4 (dec: 996)
TPDO1 Type 255
TPDO2 Type 255
TPDO3 Type = TPDO2 Type
TPDO1 Timer 5000 ms
TPDO2 Timer 5000 ms
TPDO3 Timer = TPDO2 Timer
TPDO4 Timer (level = TPDO2 Timer
sensors only)
CAN enabled 0
Tab. 4: CANopen default configuration
After configuring the CAN interface for the available CANopen
network, the CAN interface of the sensor can be enabled and
the sensor can be connected to the CANopen network.
The procedure for communicating with the sensor with CAN
communication via RS232 port enabled is described in the de-
tailed operating instructions (download from www.buehler-
technologies.com).
