1 Introduction
This manual describes the operation of the Modbus configuration program Modbus Tool.exe of GO Systemelektronik in version 1.07 with the article number 420 6500 for the following sensors:

Modbus sensor BlueTrace Oil in Water BlueTrace Crude Oil BlueTrace Turbidity BlueEC Conductivity

Article number 461 6200 461 6300 461 6780 461 2092

The program automatically recognises the connected Modbus sensors. Modbus Tool.exe is included with the above-mentioned Modbus sensors of GO Systemelektronik.

With Modbus Tool.exe you can, for example, read out sensor information, assign a Modbus address, determine the internal amplification of the input signal, calibrate the sensor and display measurement values.

The program runs under Windows 7 and newer. An Installation is not necessary; the program starts when Modbus Tool.exe is called up.

The products of GO Systemelektronik are constantly being developed, therefore deviations between this manual and the delivered product can result. Please understand that no legal claims can be derived from the contents of this manual.

Modbus Sensor Configuration
2 Preparation
To enable your PC to communicate with a Modbus sensor, you need a converter from RS485 to USB and driver software. Here, as an example, the Modbus USB converter of GO Systemelektronik (article number 486 S810) with the driver software at: https://ftdichip.com/drivers/d2xx-drivers there ,,D2XX Drivers" The driver software creates a virtual COM port in the Windows system ­ in this example "USB Serial Port (COMn)". A Modbus sensor is connected via the clamp socket strip in slot X1. If a Modbus sensor is to be connected to a BlueConnect module of GO Systemelektronik, the clamp socket strip from the BlueConnect module can be used at slot X1. Exception: If a Modbus sensor is to be connected to the BlueSense Transducer of GO Systemelektronik, the clamp socket strip on the BlueSense Transducer can be used at slot X2. In case of communication problems:
Check the earth connection of the converter. Install the latest driver.
Earth the converter. This is the only way to ensure trouble-free operation.
The earth connection is on the left side of the housing.

In the start window you can · establish the connection with your PC via a selected COM Port, · automatically recognise connected Modbus sensors, · and change the Modbus Slave ID of detected Modbus sensors.
After starting the program, the Modbus connection window opens. Click on button <Start> .
The Select Port window opens. Select the correct COM Port for communication with the converter. Via <Change COM Port> you can afterwards change the COM Port.

Modbus Slave ID: The value entered here (default value is 1 - quick selection 1 to 16 or input 1 to 230) is the start value from which the program searches for the next Modbus Slave ID of a connected sensor after clicking the <Start> button . If the program does not find a sensor with this Modbus Slave ID, the message "No Modbus sensor was found !!!" appears.
Reset to 1: The Modbus Slave ID of a detected Modbus sensor is set to 1 and the value in is set to 1.
Change ID: The Modbus Slave ID of a detected Modbus sensor is set to the entered value (1 to 230) and the value in is set to the same value.

Modbus Sensor Configuration 3.4 The BlueTrace Calibration Window BlueTrace Oil in Water / BlueTrace Turbidity > Calibration 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 polynomial is created. Example with a 2. Order polynomial:

Calibration coefficients
Note: BlueEC Conductivity does not have a calibration window.

 A raw sensor value is the uncalibrated sensor reading.

3.4.1 The Calibration Table

There are two ways to enter the raw values

· manual input

­ gives the possibility to calculate hypothetical calibrations

· measurement value transfer ­ current measured raw values for the actual calibration

Reference values are always entered manually. You can enter up to 10 value pairs.

,,measured value [ppm]" is the reference value of a calibration liquid.

Note: Decimal separator is the comma; dots are not accepted.

Manual input:

not activated: Measure

After the first opening of the calibration window, the cali-

bration table has only one row. Click with the cursor in the

"raw value" cell and enter the first raw value, click with the

cursor in the "measured value" cell and enter the first refer-

ence value, or vice versa. Measurement value transfer:

CRC 2 bytes

Description

Address: Function code: Data: CRC:

Sensor address (valid from 1 ­ 230) Address 0 is the broadcast address and will not be answered.
Here you define whether parameters are to be read or written.
e.g. from the master: Which parameters are requested? e.g. from the slave: content of the requested parameters
CRC16

Data types Standardized data types:
Extended data types:

byte (8-bit) and short integer (16-bit) According to the Modbus specification, a register always transmits the high-byte first, followed by the low-byte.
32-bit integer and 32-bit float are transmitted as 2 consecutive 16-bit registers. The format of the float number corresponds to the IEEE standard 754.
