Setting the device address

The device address must always be configured for a Modbus slave. The valid device
addresses are in the range from 1 to 247. Each address may only be assigned once in a
Modbus RS485 network. If an address is not configured correctly, the measuring device is
not recognized by the Modbus master. All measuring devices are delivered from thefactory with the device address 247 and with the "software addressing" address mode.

Check that the housing seals are clean and fitted correctly.

2.

Dry, clean or replace the seals if necessary.

3.

Tighten all housing screws and screw covers.

4.

Firmly tighten the cable glands.

Modbus data map

Function of the Modbus data map
The device offers a special memory area, the Modbus data map (for a maximum of 16
device parameters), to allow users to call up multiple device parameters via Modbus RS485
and not only individual device parameters or a group of consecutive device parameters.
Grouping of device parameters is flexible and the Modbus master can read or write to theentire data block simultaneously with a single request telegram.

Structure of the Modbus data map
The Modbus data map consists of two data sets:• Scan list: Configuration area
The device parameters to be grouped are defined in a list by entering their Modbus
RS485 register addresses in the list.
• Data area
The measuring device reads out the register addresses entered in the scan list cyclicallyand writes the associated device data (values) to the data area.
For an overview of device parameters and their corresponding Modbus register
information, refer to the "Modbus RS485 register information" section in the"Description of device parameters" documentation →  188.

Write protection via access code

The effects of the user-specific access code are as follows:• Via local operation, the parameters for the measuring device configuration are writeprotected and their values can no longer be changed.
• Device access is protected via the Web browser, as are the parameters for the measuring
device configuration.
• Device access is protected via FieldCare or DeviceCare (via CDI-RJ45 service interface), as
are the parameters for the measuring device configuration.

Parameters which can always be modified via the local display
Certain parameters that do not affect the measurement are excepted from parameter write
protection via the local display. Despite the user-specific access code, they can always be

Via Web browser, FieldCare, DeviceCare (via CDI-RJ45 service interface), fieldbus
You can only obtain a reset code from your local Endress+Hauser service organization.
The code must be calculated explicitly for every device.

11.8

Adjusting the measured value with the aid of wizards

In practice, the measurement typically needs to be adjusted based a reference value (e.g.
lab value) when commissioning the device to ensure optimum measurement performance
during subsequent operation. Repeating this adjustment is recommended if there are
significant changes to the process conditions or following replacement of the sensor
electronics module (ISEM).
The deviation from the value determined by the device can be checked and adjusted if
necessary with the aid of manually taken samples of the medium, which are analyzed in
the laboratory. The lab value is compared with the measured value of the device for thispurpose. The difference between the two values can then be used to decide whether themeasurement performance is sufficient or whether the device should be readjusted basedon the laboratory value.
The device has four wizards to facilitate this process. After starting each wizard, you are
guided through the necessary work steps.
Performing the basic settings for the adjustment:
1.

Commissioning wizard

Adusting the measured value based on the reference value:
2.

1 - Take a sample wizard

3.

2 - Enter lab value wizard

4.

3 - Perform adjustment wizard
Adjustment can be carried out directly via local operation of the device or via the web
server.
The process using the wizards is essentially the same for both operation methods, butmore options and a graphic display are available when operating via the web server inthe 3 - Perform adjustment wizard. Using the web server is therefore recommended.

Online information
Further information on the procedure for performing an adjustment using wizards is alsoavailable online.

11.8.1

Performing the basic settings for the adjustment

The Commissioning wizard is called up via the main menu: Setup → Total solids
adjustment → Commissioning
Commissioning
The Commissioning wizard is used to:• set the system time (when using the wizard for the first time or after disconnecting thedevice from the supply voltage)• set the unit for the solids content for the measured total solids and the lab value• enter the solids density

11.8.2Adjusting the measured value based on the reference value• All three wizards must be run each time the device is adjusted.
• You can call up the wizard options via the operating menu or during local operationfrom the operational display by holding down the Enter key for longer than
3 seconds→  132.

Endress+Hauser

Proline Teqwave MW 300 Modbus RS485

Operation

Taking a sample
The 1 - Take a sample wizard is used to:• set the system time (if not already defined in the Commissioning wizard)• have the total solids measured by the device• calculate the value of the medium sample of the device
The calculated medium sample of the device is the average of the total solids
measured by the device between the start and end of the wizard.
• perform a check as to whether the variability is within the permitted limits You can set
the upper limit in the Maximum variance parameter.
• save the value of the sample calculated by the device (incl. system time and status).
• At the same time as the total solids in the device are measured, a sample must be
taken manually for analysis in the laboratory.
• The installation of sampling points is recommended for taking samples of themedium →  24.
Entering the lab value
The 2 - Enter lab value wizard is used to:• select a unit for entering the sample of the medium taken manually.
• select the sample measured by the device that is to be used for the lab value• enter the lab value of the sample of the medium taken manually• check whether the lab value is within the value range• save the lab value (incl. status and min./max. values if applicable)
Performing the adjustment
The 3 - Perform adjustment wizard is used to:• display the respective medium sample with the corresponding lab values and the numberof adjustments performed.
• select whether a single-point adjustment or a multi-point adjustment is to be performed• In the case of a single-point adjustment, the value of the most recent, valid sample
taken is always selected automatically.
• In the case of a multi-point adjustment, the values of the last ten valid samples arealways selected automatically.
• display the current and new factor and offset• display the current and new value of the total solids• display the time stamp of the completed process and confirm completion.
Each completed adjustment is documented: Diagnostics → Event logbook → Event list
Extended functionality when running the wizard via the web server
In the web server, the samples of the medium are displayed in a table (max. 10 out of 32
stored samples). It is also possible to adjust the selection of samples used for the
adjustment.
• In the case of a single-point adjustment, the value of the most recent, valid sample taken
is always selected automatically. You can determine the most recent sample you want touse by deleting the most recent sample in the table.
• In the case of a multi-point adjustment, the values of the last ten valid samples taken arealways automatically selected. You can determine the samples you want to use for the
adjustment by deleting samples from the table.

Application

The measuring device is suitable only for the measurement of solids in water-based
liquids.
Depending on the version ordered, the measuring device can also measure potentiallyexplosive media.
To ensure that the device remains in proper operating condition for its service life, use themeasuring device only for media against which the process-wetted materials are
sufficiently resistant.

16.2
Measuring principle

Function and system design

Microwave transmission
Total solids measurement via microwave transmission: The device measures the time offlight and absorption of microwave transmission between two antennas facing each otherin the measuring tube. Based on these variables, the permittivity of the medium can becalculated, for example.
The temperature of the medium is determined in order to calculate the compensation
factor due to temperature effects. This signal corresponds to the process temperature andis also available as an output signal.
The conductivity of the medium is derived from the change in amplitude and phase of the
microwave signal.

Measuring system

The device consists of a transmitter and a sensor.
The device is available as a compact version:
The transmitter and sensor form a mechanical unit.

data management

The measuring device features HistoROM data management. HistoROM data management
comprises both the storage and import/export of key device and process data, making
operation and servicing far more reliable, secure and efficient.
When the device is delivered, the factory settings of the configuration data are stored
as a backup in the device memory. This memory can be overwritten with an updated
data record, for example after commissioning.
Additional information on the data storage concept

There are different types of data storage units in which device data are stored and used by the device:
