2 Description of the BlueConnect Modules
The BlueConnect Modules
•Transmit the measured values of analog sensors via CAN bus and Modbus.
•Transmit the measured values of Modbus sensors via CAN bus.
•Transmit the measured values of sensors to a PLC.
•Control a RS232 Interface via CAN bus.
•Transmit the current values of analog current outputs via CAN bus and Modbus.
•Control an RS232 interface via CAN bus.
BlueConnect Modules are available in four basic variants: as Sensor Module, Bus Module, Current Module and

Notes on termination of older BlueConnect Modules
Older modules have no slide switches on the board.
With older BlueConnect Senor and Bus Modules, the termination of CAN bus and
Modbus is done via the configuration program Modbus Tool.exe.
see 4.7 Configuring Older Bus Modules
Older modules are not terminated at the factory.
If there is no possibility to terminate the CAN bus via the configuration program:
CAN bus termination by means of a resistor of approx. 120 Ω on the open terminals
for CAN-H and CAN-
L on slot X4. Modbus termination by means of a resistor of
approx. 120 Ω on the open terminals for TX/RX+ and TX/RX- on slot X3.

4 Configuring the BlueConnect Modules with the Program Modbus Tool.exe
This chapter describes the operation of the BlueConnect configuration program Modbus Tool.exe of
GO Systemelektronik with the article number 420 6500 in software version 1.07. For example, you can use it
(depending on the type of module and sensor) to read out sensor information, assign a Modbus address,
calibrate the sensor and display measurement values.
On older Sensor and Bus Modules without slide switches, the Modbus (RS485) and the CAN bus can be
terminated.1
The configuration of the Bus Module is done automatically. The exception here are older bus
modules, see 4.11 Configuring Older Bus Modules.
The configuration of the Bus Module Turbidity flow through is done at the BlueBox and is not
described here.
The calibration of the Sensor Modules can also be done via the menu operation on the BlueBox
and with the BlueBox PC Software.
The calibration of the Current Modules can also be done via the menu operation on the BlueBox
and with the BlueBox PC Software.
The
configuration of the RS232 Module
is done via DIP switches.
see 3.2 Cable Connections, Switch Positions and LEDs there RS232 Modul
Decimal separator is the comma.
The program is executable under Windows 7 and newer. An Installation is not necessary, the program starts
when Modbus Tool.exe is called up.
The program automatically detects the connected modules with their sensors.
Modbus Tool.exe is included with every BlueConnect Module.2
In the program windows, the internal designations of the modules are used:
•| pH + Temp. = BlueConnect pH | ISE + Temp. = BlueConnect ISE |
| ORP + Temp. = BlueConnect Redox |
•| Oxygen = BlueConnect O2 | Conductivity = Conductivity | Oil in Water = BlueTrace Oil in Water |
| Turbidity = BlueTrace Turbidity |
•| Current Input Module = BlueConnect Current In | Current Output Module = BlueConnect Current Out |
4.1 Preparation
In order for your PC to communicate with a Modbus
sensor,
you need a converter from RS485 to USB and driver software.
As an example, here is the Modbus USB3converter of GO Sys-
temelektronik (Article No. 486 S810) with the driver soft
ware
at:
https://ftdichip.com/drivers/d2xx-drivers there „D2XX Drivers“
The driver software creates a virtual COM Port in the Win
dows
system – in this example "USB Serial Port (COMn)".
Converter Slot X1
connected with
BlueConnect Module Slot X3
In case of communication problems:
•Check the earthing of the converter.
• Install the latest driver software.

4.4 The Info Window
After the program has detected the connected module (here Redox/ORP), the module info window opens.
4.5 The Calibration Window
A calibration compares the value pairs of the measured sensor raw values∗and allocated reference values
from calibration liquids. These value pairs are taken as points in a coordinate system. The curve of a 1. to 5.
Order polynomial is placed through these points as accurately as possible, this is how the calibration polyno-
mial is created.
Example with a 2. Order polynomial:
∗A raw sensor value is the uncalibrated sensor measurement value or the uncalibrated current input value.

After first opening the calibration view the calibration table
has only one row. Click the cursor on the first row
pushbutton : As long as the row pushbutton is active
the current measurement raw value appears in the “raw
value” cell. Click the cursor into the “measured value cell”
and enter the first reference value.
To create a new row, click the cursor into th
e last row with
an entry and press the ENTER-key.
To delete a row
, delete all row entries and click in another
row.

4.8.2 The Calibration Window O2
The calibration of the O2 sensor is a two-point calibration (calibration degree 0 poly-
nomial). One point is the zero point, the other is determined by the saturation in air
(100 %) or a pair of measured values from the measurement value of the sensor and
the measurement value of a reference measurement device in the same measure-
ment medium.
Starts and stops the measurement display,
the measurement values are displayed every sec-
ond.
Reference calibration
Prerequisite: Setting O2 Unit mg/l see 4.8.1The Parameter Window
1. Click on <Start>
2. Immerse the oxygen sensor in your measurement medium and wait,
until the displayed values are stable.
3. Entering1the oxygen content of the measurement medium according to the
reference measuring device
4. Click on <mg/l Calibration>.
5. The calibration is completed.
Saturation calibration
Prerequisite: Setting O2 Unit % see 4.8.1 The Parameter Window
1. Click on <Start>.
2. Hold the oxygen sensor in the air.2
Wait at least 10 minutes until the displayed values are stable.
3. Click on <100% Calibration>.
4. The calibration is completed.
Note:Decimal separator is the comma; if a dot is entered, an error message appears.
1Decimal separator is the comma; if a full stop is entered, an error message appears.
2The galvanic cell for oxygen measurement is located at the bottom of the sensor body, the temperature sensor is near the
center. Therefore, a saturation calibration in the air can only be carried out when the entire sensor body has reached the tem-
perature of the ambient air. The larger the difference in temperature between the measuring medium and the ambient air, the
greater the time required for a temperature adjustment (30 minutes or more, if applicable).
The temperature adjustment can be accelerated by immersing the sensor in water, which has approximately the temperature
of the ambient air, before performing the saturation calibration.
Moreover, abrupt temperature changes (e.g., by direct exposure to the sun) must be avoided.

Older BlueConnect Bus Modules do not have slide switches on the board. Here, the termination is done via
the Parameter Window.
RS485 Termination
Selection Modbus (RS485) termination selection on/off
CAN Termination
Selection CAN bus termination on/off
Writes the selected termination into the module memory.
Settings that have not yet been saved are marked in red.
Only applies to older BlueConnect Bus Modules, the newer ones are terminated with slide
switches on the board, see 3.2 Cable Connections, Switch Positions and LEDs
there also
Notes on termination of older BlueConnect Modules.
Newer modules with slide switches ignore the setting.
With older BlueConnect Bus Modules, connected Modbus sensors are not automatically detected. The
appropriate sensor identifier must be selected via the drop-down menu.
Writes the selected sensor identifier into the module memory.
