Disposal

➢ Devices no longer in use or beyond a state of repair must be disposed of in an

environmentally responsible manner by an authorised collection point. They must never be treated as ordinary household waste.

➢ We can undertake the environmentally responsible disposal of devices sold by

Technische Alternative upon request.

➢ Packaging material must be disposed of in an environmentally responsible manner. ➢ Incorrect disposal may result in considerable damage to the environment, as many

of the materials used require professional handling.

Standard delivery

• CAN-BC2 CAN bus converter

• 2x terminal (4-pole)

• 2x terminal (2-pole)

• Plastic wall plugs

• Clamping plate screw

• Operating instructions

Installing and connecting the device

The CAN-BC2 is integrated into a distribution box or fitted to a level mounting surface in a dry room, in accordance with local regulations. It can be snapped onto a top-hat rail (TS35 DIN support rail to EN 50022) or bolted onto the mounting surface via the 2 holes in the casing tray.

Unscrew the 4 screws on the front and lift the cover.

Fixing dimensions and measurements

Installing and connecting

Power supply

The bus converter requires a 12 V power supply provided by the CAN bus network. The supply comes from one side of the CAN bus network only, as the other side is potential-free, i.e. the 12 V power supply is not looped through.

CAN bus cable selection and network topology

The principles of CAN bus cabling are described extensively in the manuals for the freely programmable controllers and must be observed.

This manual describes only certain features that are specific to this device. Each CAN network must be provided with a 120 ohm bus terminator at the first and last network node

(termination – with plug-in jumper). A CAN network therefore always has two terminators (one at each end). The potential-free separation by the bus converter requires a plug-in jumper to be set in accordance with the CAN network topology. This jumper is located on either side of the CAN bus.

Potential-free CAN bus network (CAN bus 2)

Installing and connecting

Example: Network across several buildings with CAN bus converter CAN-BC2

Key to symbols:

… Device with its own power supply (UVR16x2, RSM610, UVR1611)

… Device is supplied by the bus (CAN I/O, CAN-MT, …)

… CAN bus converter (CAN-BC2)

… Terminated (end devices) … Open termination

… CAN bus surge arrester ... Gas discharge arrester for indirect earthing e.g. CAN-UES, CAN-UES2

With CAN bus surge arresters: The screen of the disconnected network is connected to CAN bus earth (GND) for each bus converter. This screen must not be directly earthed.

The CAN bus converter is similar to a repeater. It receives CAN bus signals and passes them on. Each cable run on either side of the CAN bus converter must therefore be viewed as an independent CAN bus network.

Max. cable length: Subject to bus rate set in the disconnected network (CAN bus 2)

Indirect earthing

optional

Installing and connecting

Without CAN bus surge arresters: This version only protects against potential differences up to 1 kV and cannot be considered to offer lightning protection. In this case, the cable screen must be earthed at a single point between the CAN bus converters, as close to the cable centre as possible. We recommend earthing the screen indirectly in the other buildings using a gas discharge arrester.

Branch cables

As a general principle, branch cables are not permitted in a CAN bus network. The CAN bus converter is used to provide reliable long branch cables. This means the branch cable is

disconnected from the other CAN bus network and can be viewed as an independent CAN bus network.

Independent CAN bus network

Indirect earthing

optional

Installing and connecting

DL bus and M-Bus connections

The polarity of the M-Bus connection is reversible.

Data link for DL bus

The DL bus has 2 wires: DL and GND (sensor earth). The DL bus itself supplies the power supply for the DL bus sensors.

Cables can be routed with a star topology or in series (from one device to the next). Any cable with a cross-section of 0.75 mm² up to 30 m in length can be used as a data link. For longer

cables, we recommend the use of a screened cable. Long cable conduits routed closely next to each other for mains and data links result in faults being

induced into the data link from the mains. We therefore recommend a minimum clearance of 20 cm between two cable conduits or the use of screened cables.

Never run the data link together with a CAN bus cable or M-Bus cable in the same conduit.

Bus load from DL sensors

A 2-pole cable provides both the power supply and the signal transfer from DL bus sensors. An additional power supply by means of an external power supply unit (such as with the CAN bus) is not possible.

Take the "bus load" into consideration as sensors have a relatively high current demand: The bus converter supplies the maximum bus load of 100 %. The bus loads of the electronic sensors

are listed in the technical data of the relevant sensors. Example: The electronic sensor FTS4-50DL has a bus load of 25 %. Consequently up to four

FTS4-50DL sensors can be connected to the DL bus.

M-Bus cable

The M-Bus has 2 wires: M-Bus and GND (sensor earth). The power supply for reading data from MBus devices is provided by the bus converter.

Cables can be routed with a star topology or in series (from one device to the next). Ring topology is not permitted.

A two-wire screened cable is used as the M-Bus cable (e.g. telephone cable J-Y(ST)Y 2 x 2 x 0.8 mm). The maximum total cable length depends on the number of M-Bus devices connected and the cable cross-section.

Never run the M-Bus cable together with a CAN bus cable or DL bus cable in the same conduit.

Principles

The CAN bus converter makes additional interfaces available for all CAN bus devices. Furthermore, all the function modules in the X2 range are available. These allow bus input values to

be processed directly in the bus converter. The results of the functions can be transferred to other devices as network outputs, visualised or logged.

It is programmed using TAPPS2 software. The CAN-BC2 can be operated via the UVR16x2 controller, via CAN-MTx2 or via the C.M.I. interface.

Minimum system requirements

Programming: TAPPS2 version 1.10 Programming Visualisation: TA-Designer version 1.17 Access: C.M.I. version 1.26.2

UVR16x2 version V1.23 CAN-MTx2 version V1.09

Datalogging: Winsol version 2.07

Interfaces

Potential-free CAN bus with increased interference resistance

The CAN-BC2 is used for remote connection within a controller network or by network groups. This could be several groups of CAN bus connections and/or further remote CAN bus subscribers, for example in a heating system.

This interface is electrically isolated from the primary CAN bus via an optical transmission path. We recommend using a bus converter at both ends of a long cable, so that no critical electronic parts

are directly connected to the bus over the entire remote connection. The CAN-BC2 protects against potential differences of up to 1 kV and can therefore not be considered to offer voltage surge protection in the case of a lightning strike.

Note: Every CAN bus subscriber is identified with its own CAN node number from a total of 62 possible node numbers. When designing the network, bear in mind that a bus converter does not disconnect the networks from a data point of view and therefore does not increase the number of nodes available. As bus subscribers, every single converter is given its own node number. This individual number is identical for both CAN sides (primary and potential-free).

M-Bus (measurement bus)

The M-Bus is a master/slave system for reading data from energy and volume meters (electricity, heat, water, gas).

The CAN-BC2 is designed for up to 4 M-Bus "unit loads". Up to 4 M-Bus meters, each with 1 unit load, can therefore be connected. The bus converter (master) cyclically reads the values from the individual devices. The interval time is adjustable.

As a master, this bus converter is therefore suitable for the parallel connection of up to four M-Bus meters (slaves).

In total, a maximum of 32 M-Bus values can be read per bus converter. There must only be one

master in the M-bus system.

Principles

DL bus

The DL bus was developed by Technische Alternative and is designed to read measurements from DL sensors.

It has just 2 wires: DL and GND (sensor earth). The DL bus itself supplies the power supply for the DL bus sensors.

Modules

The number of interfaces can be increased through the use of modules. Only one extension module can be used at a time in the CAN bus converter. These modules are described extensively in their own manuals.

KNX module MD-KNX

This module helps to make it possible to connect the CAN bus network to the KNX bus network. Up to 64 values can be exported to the KNX bus and 64 values can be imported from the KNX bus.

Modbus/M-Bus module

This module has a Modbus RTU 485 interface which can be configured as either master or slave. Up to 64 values can be exported to the Modbus and 64 values can be imported from the Modbus. In addition, the module has an interface for reading data from a further four M-Bus meters. A further 32 M-Bus values can therefore be read.

Programming with TAPPS2 / Designations

Programming with TAPPS2

The following describes how to program the parameters for all elements using the TAPPS2 programming software.

Designations

All elements can be designated by selecting a predefined designation from various designation groups or from the user defined designations.

You can also assign a number from 1 to 16 to every designation.

User defined designations

Up to 100 different designations can be defined by the user. The maximum number of characters per

designation is 24. Designations defined previously are available for all elements (functions, fixed values, bus inputs and

outputs).

Example:

You want to assign a user defined designation to CAN input 1.

Click the field for creating the required designation.

Programming with TAPPS2 / Designations

Enter the designations, finish with "OK"

Select from the list of previously created user defined designations.

The required designation is displayed

Programming with TAPPS2 / Fixed values

Fixed values

In this menu you can define up to 64 fixed values, which can be used as input variables for functions, for example.

Example:

Fixed value type

Once the required fixed value is selected, the fixed value type can be defined.

• Digital

• Analogue

• Pulse

Digital

Select the measured variable:

• Off / On

• No / Yes

Select whether the status can be changed via a selection box or simply by a click.

Programming with TAPPS2 / Fixed values

Analogue

Select from a wide range of units and dimensions

After assigning the designation, you must define the permitted limits and the current fixed value. The value can be adjusted in the menu within those limits.

Pulse

A fixed value of this type allows short pulses to be generated by tapping it in the menu. Example:

Select the function quantity: when activated, either an ON pulse (from OFF to ON) or an OFF pulse (from ON to OFF) will be generated, depending on the selection made here.

Programming with TAPPS2 / Fixed values

Designation

Enter the fixed value designation by selecting a predefined designation or one of the user defined designations.

You can also assign a number from 1 to 16 to every designation.

Restriction of change authority

For all fixed values, you can set the user level from which the fixed value can be changed:

Programming with TAPPS2 / Functions

Functions

You can choose from 41 different functions and create up to 22 functions. Functions can also be

applied multiple times. Input variables are assigned to every function. The input variables provide the function with all the

data required for the internal decision. Each function can be activated or deactivated with "Enable". Within each function, data and parameter settings are utilised in order to calculate the decisions and

set values, which are then made available as output variables. A function can therefore only perform tasks in the overall system when connected by its respective

input and output variables to other parts of the system (other functions or the network). The individual function modules are described in the UVR16x2, RSM610 and CAN-IO 45 manuals. This

manual only provides general information on how to program functions.

Selecting a new function

Working with TAPPS2 is described in the manual for TAPPS2 (see "Help / Manual" menu item or "F1" key in TAPPS2).

Designation

After selecting and inserting the function in the drawing interface, you define the function designation. Example: Analogue function

Enter the function designation by selecting a predefined designation from a "general" designation group or from user defined designations.

You can also assign a number from 1 to 16 to every designation. How to create user defined designations is described in the "Designations" chapter.

Programming with TAPPS2 / Functions

Input variables

Input variables constitute the link to output variables from other function modules or other sources. The descriptions of the function modules state the signal type for every input variable. Digital input

signals (ON/OFF) can be applied as standard or inverse. Every function module has the "Enable" input variable, which represents the fundamental activation of

the entire function. It permits simple blocking or enabling of the entire function by means of a digital

signal (ON/OFF). Example: Analogue function

The following source types are available to choose from:

• User

• Functions

• Fixed values

• System values

• DL bus

• CAN bus analogue

• CAN bus digital

• M-Bus

• KNX bus (only if module is fitted)

• Modbus (only if module is fitted)

Important: For every input variable, it is important to note the input signal type:

Analogue (numeric value) or digital (OFF/ON).

Programming with TAPPS2 / Functions

Certain input variables are always essential for the function to operate and cannot be set to "unused". They appear in purple in TAPPS2 and are highlighted in the description of the functions. Others can be optionally linked to sources.

Example: TAPPS 2

Depiction in the manual:

After linking to the source, you define which information (which variable) from the source will be transferred to the function.

Example: CAN bus analogue

• Measurement – the value measured

• RAS mode – subject to the setting of the switch on the room sensor (RAS, RASPT, RAS-PLUS,

RAS-F), the following analogue values will be issued:

Automatic 0 Standard 1 Lowered 2 Standby 3

• Sensor error – digital value; ON if a sensor error occurs

• Network error – digital value; ON if a timeout is active (= error). This application is not yet

available for the M-Bus.

When linked to a function, the output variables are displayed for selection.

Programming with TAPPS2 / Functions

Parameters

These parameters are values and settings which are specified by the user. They are settings which allow users to adjust the module to match the properties of their system. Example: Comparison function

The parameters menu may also be divided into further sub-menus in the C.M.I. view, depending on the function.

If optional sensors are not used, the settings for them are shown in grey and they cannot be programmed.

Example: Solar control, limit temperature input variable is unused

Programming with TAPPS2 / Functions

Hystereses

Many parameters have adjustable start and stop differentials which have the effect of a switching hysteresis.

Example:

Demand temperature in the Heating demand function

Demand is triggered at T.dem. set + Diff. on (= 61 °C); shutdown is triggered at T.dem. set + Diff. off (= 69 °C).

The values of Diff. on and Diff. off can also be negative, but are always added to the set temperature.

Example of a negative Diff value:

Here, demand is triggered at T.dem. set + Diff. on (= 51 °C); shutdown is triggered at T.dem. set + Diff. off (= 60 °C).

Schematic diagram of start and stop differentials for MAX and MIN thresholds

Programming with TAPPS2 / Functions

Some input variables can be either defined by the user or linked to other sources (inputs, functions, etc.). If they are not linked, their value is defined in the parameters area by the user instead. However, if the link is set up, the value will be displayed in grey in the parameters area and "I.V." will be given as the value.

Example: Comparison function

Value B was not linked in the input variables and must therefore be defined in the parameters.

Value B was linked in the input variables, so the value is shown in grey in the parameters with "I.V.".

Programming with TAPPS2 / Functions

Function quantities (units)

In many functions you can choose from a wide range of function quantities. These function quantities have units with varying numbers of decimal places.

In all function calculations (exception: curve function), the units are converted to the smallest unit in each case (l/min to l/h; min, h and days to s; MWh to kWh; m/s to km/h; m and km to mm; mm/h and mm/min to mm/day; m³/h and m³/min to m³/day)

Programming with TAPPS2 / Functions

Output variables

Output variables represent the results of the function module. They can serve as the input variables for another function, or can be linked to bus outputs. A single output variable can also be linked multiple times to function input variables or bus outputs.

The number of output variables varies greatly depending on the function. Example: In the "Comparison" function there are just 3 output variables; in the "Heating circuit"

function there are 23.

Important: For every output variable, it is important to note the type of variable value for further

links:

Analogue (numeric value) or digital (OFF/ON).

Programming with TAPPS2 / CAN bus

CAN bus

The CAN network allows communication between CAN bus devices. When analogue or digital values are sent via CAN outputs, other CAN bus devices can utilise those values as CAN inputs.

Up to 62 CAN bus devices can be operated in one network. Every CAN bus device must be given its own node number in the network.

The cable topology of a CAN bus network is described in the installation instructions. If a CAN input or CAN output is inserted into the drawing, the device settings can be defined for the

first time. These settings then apply to all other CAN elements as well.

CAN settings for the converter

The bus rate setting only applies to the primary CAN bus network.

These settings can also be made in the "File / Settings / Device settings..." menu:

Primary CAN bus network Potential-free CAN bus network

Node

Definition of a unique CAN node number (setting range: 1-62). The node number applies to both sides of the bus converter. The factory-set node number of the converter is 48.

Programming with TAPPS2 / CAN bus

Bus rate

The standard bus rate of the CAN network is 50 kbit/s (50 kBd), which is preset for the CAN bus devices. An individual bus rate can be set for each side of the CAN bus converter ("CAN bus 2" = potential-free, disconnected CAN bus network).

Important: All devices on any one side of the CAN bus network must have the same transfer

rate in order to be able to communicate with each other.

The bus rate can be set to between 5 and 500 kbit/s, with lower bus rates allowing longer cable networks (see installation instructions).

Designation

Every converter can be given its own designation.

Datalogging

This menu is used to define the parameters for CAN datalogging of analogue and digital values.

There are no preset values.

Example: Some analogue values have already been defined for CAN datalogging

Programming with TAPPS2 / CAN bus

CAN datalogging requires C.M.I. version 1.26.2 or higher and Winsol version 2.07 or higher.

CAN datalogging is only possible with the C.M.I. datalogger. The data to be logged can be freely selected. There is no constant data output. When requested by a C.M.I., the bus converter saves the current values to a logging buffer and locks this to prevent overwriting (if requests are received from another C.M.I.) until the data is read, at which point the logging buffer is enabled again.

The settings required on the C.M.I. for datalogging via CAN bus are described in the C.M.I.'s online help.

Each bus converter can issue a maximum of 64 digital and 64 analogue values that are defined in the "CAN bus/datalogging" menu.

The sources for the values to be logged can be M-Bus / DL bus / CAN bus inputs, function output variables, fixed values and system values.

All counter functions (energy meters, heat meters, counters)

Any number of counter functions (but a maximum of 64 analogue values) can be logged. Like all other analogue values, the counter values to be logged are entered into the "Analogue datalogging" list.

Programming with TAPPS2 / CAN bus

CAN analogue inputs

Up to 64 CAN analogue inputs can be programmed. They are defined by specifying the transmission node number and the number of the transmission node's CAN output.

Node number

After the node number of the transmission node is entered, the other settings can be specified. The number of a CAN analogue output is taken from the device with that node number and applied here.

Example: On CAN analogue input 1, the value applied is that of CAN analogue output 1 from the device with node number 1.

Designation

Every CAN input can be given its own designation. The designation can be selected from various designation groups or can be user defined.

Example:

CAN bus timeout

Definition of the timeout time for the CAN input (minimum value: 5 minutes).

As long as the information continues to be imported from the CAN bus, the network error for the CAN input will be "No".

If the value has not been updated for longer than the set timeout, the network error changes from "No" to "Yes". You can then define whether the last value transmitted or a definable substitute value should be issued (only when the measured variable is set to: User def.).

The network error can be selected as the source of a function input variable, which allows the controller to react appropriately to a failure of the CAN bus or transmission node.

In System values / General, a network error for all CAN inputs is available.

Programming with TAPPS2 / CAN bus

Unit

If the measured variable is set to "Automatic", the unit of measurement specified by the transmission node will be applied in the controller.

If you select "User def.", you can select a unit of your own, a sensor correction and, if the sensor check is set to active, a monitoring function.

Every CAN input is assigned its own unit, which can differ from the unit used by the transmission node. A range of units is available to choose from.

Sensor correction: The value of the CAN input can be corrected by applying a fixed value.

Value at timeout

If the timeout time is exceeded, you can define here whether the controller should issue the last value transmitted ("Unchanged") or a definable substitute value.

Programming with TAPPS2 / CAN bus

Sensor check

If you set the sensor check to "Yes", the sensor error of the sensor supplying the CAN input is available as an input variable for a function.

Sensor error

This setting is only displayed if sensor check is active and the measured variable is set to "User def.".

If the "Sensor check" is active, the sensor error from a CAN input is available as a function input variable: status "No" for a sensor that is working correctly and "Yes" for one that is faulty (short circuit or lead break). This allows the controller to react to the failure of a sensor, for example.

If the Standard thresholds are selected, a short circuit will be indicated if the value falls below the measurement limit and a lead break will be indicated if the value exceeds the measurement limit.

The Standard values for temperature sensors are -9999.9 °C for a short circuit and 9999.9 °C for a lead break. Those values are utilised in the internal calculations in the event of an error.

By selecting suitable thresholds and values for a short circuit or lead break, a fixed value can be specified for the module in the event of sensor failure at the transmission node, to allow a function to continue operating in emergency mode (fixed hysteresis: 1.0 °C).

The short circuit threshold must be defined below the lead break threshold. In System values / General, the sensor error is available for all inputs, CAN inputs and DL inputs.

CAN digital inputs

Up to 64 CAN digital inputs can be programmed. They are defined by specifying the transmission node number and the number of the transmission node's CAN output.

Their parameters are programmed in almost exactly the same way as for the CAN analogue inputs. Under Measured variable / User def. the display for the CAN digital input can be changed from OFF /

ON to No / Yes and you can define whether the last status transmitted ("Unchanged") or a definable substitute status should be issued if the timeout time is exceeded.

Programming with TAPPS2 / CAN bus

CAN analogue outputs

Up to 32 CAN analogue outputs can be programmed. They are defined by specifying the source in the bus converter.

Link to the source in the module which supplies the value for the CAN output.

• DL inputs

• M-Bus inputs

• KNX inputs (with fitted module)

• Modbus inputs (with fitted module)

• Functions

• Fixed values

• System values

Example: Source: M-Bus input 1

Designation

Every CAN analogue output can be given its own designation. The designation can be selected from various designation groups or can be user defined.

Transmission condition

Example:

If change > 10

A new transmission will be made if the current value has changed by more than the quantity specified (1.0 K in this example) compared to the last transmitted value. In the module, the unit of the source is applied together with the corresponding decimal place.

(Minimum value: 1)

Blocking time 00:10 [mm:ss]

If the value changes within 10 seconds of the last transmission by more than 1.0 K, the value is nevertheless only transmitted again after 10 seconds.

(Minimum value: 1 sec)

Interval time 5 min

The value is transmitted every 5 minutes even if it has not changed by more than 1.0 K since the last transmission.

(Minimum value: 1 minute)

Programming with TAPPS2 / CAN bus

CAN digital outputs

Up to 32 CAN digital outputs can be programmed. They are defined by specifying the source in the bus converter.

Their parameters are programmed in exactly the same way as for the CAN analogue outputs except for the transmission conditions.

Designation

Every CAN digital output can be given its own designation. The designation can be selected from various designation groups or can be user defined.

Transmission condition

Example:

If change yes/no

Transmission of the value if a status change occurs

Blocking time 00:10 [mm:ss]

If the value changes within 10 seconds of the last transmission, the value is nevertheless only transmitted again after 10 seconds.

(Minimum value: 1 sec)

Interval time 5 min

The value is transmitted every 5 minutes even if it has not changed since the last transmission.

(Minimum value: 1 minute)

Programming with TAPPS2 / DL bus

DL bus

The DL bus acts as a bus cable for various sensors and/or for datalogging by C.M.I. or D-LOGG. The DL bus is a bidirectional data link and is only compatible with products from Technische

Alternative. The DL bus network operates independently of the CAN bus network.

This menu contains all of information and settings needed to set up a DL bus network. The cable topology of a DL bus network is described in the controller's installation instructions.

DL settings

In the "File / Settings / Device settings / DL bus" menu, you can activate or deactivate the data output for datalogging via the DL bus and for display on the RAS-PLUS room sensor. The

C.M.I. is used for DL datalogging. Only the input and output values and the 2 heat meters are included in the data output; the values of the network inputs are not included.

DL input

Sensor values from DL bus sensors are transferred via a DL input. Up to 32 DL inputs can be programmed.

Example: Programming the parameters of DL input 1

Available for selection: Analogue or digital

DL bus address and DL bus index

Every DL sensor must have its own DL bus address. Setting the address of a DL sensor is described in the sensor's datasheet.

Most DL sensors can measure various different values (e.g. flow rate and temperatures). Every value measured must be given its own index number. The applicable index number can be found in the DL sensor's datasheet.

Programming with TAPPS2 / DL bus

Designation

Every DL input can be given its own designation. The designation can be selected from various designation groups or can be user defined.

Example:

DL bus timeout

As long as the information continues to be imported from the DL bus, the network error for the DL input will be "No".

If the controller scans the DL sensor value three times and no value is transmitted, the network error changes from "No" to "Yes". You can then define whether the last value transmitted or a definable substitute value should be issued (only when the measured variable is set to: User def.).

The network error can also be selected as the source of a function input variable, which allows the controller to react appropriately to a failure of the DL bus or DL sensor.

In System values / General, a network error for all DL inputs is available.

Unit

If the measured variable is set to "Automatic", the unit of measurement specified by the DL sensor will be applied in the controller.

If you select "User def.", you can select a unit of your own, a sensor correction and, if the sensor check is set to active, a monitoring function.

Every DL input is assigned a unit, which can differ from the unit used by the DL sensor. A wide range of units is available to choose from.

Sensor correction The value of the DL input can be corrected by applying a fixed differential value.

Value at timeout

This setting is only displayed if the measured variable is set to "User def.". If a timeout is set, you can define here whether the controller should issue the last value transmitted

("Unchanged") or a definable substitute value.

Programming with TAPPS2 / DL bus

Sensor check

If you set the sensor check to "Yes", the sensor error of the sensor supplying the DL input is available as an input variable for a function.

Sensor error

This setting is only displayed if sensor check is active and the measured variable is set to "User def.".

If the "Sensor check" is active, the sensor error from a DL input is available as a function input variable: status "No" for a sensor that is working correctly and "Yes" for one that is faulty (short circuit or lead break). This allows the controller to react to the failure of a sensor, for example.

The Standard values for temperature sensors are -9999.9 °C for a short circuit and 9999.9 °C for a lead break. Those values are utilised in the internal calculations in the event of an error.

By selecting suitable thresholds and values for a short circuit or lead break, a fixed value can be specified for the module in the event of sensor failure, to allow a function to continue operating in emergency mode (fixed hysteresis: 1.0 °C).

The short circuit threshold must be defined below the lead break threshold. In System values / General, a sensor error for all inputs, CAN inputs and DL inputs is available.

DL digital inputs

The DL bus is configured for the transfer of digital as well as analogue values. However, there is not yet any use for this at present.

The parameters are programmed in almost exactly the same way as for the DL analogue inputs. Under Measured variable / User def. the display for the DL digital input can be changed to No / Yes.

Bus load from DL sensors

A 2-pole cable provides both the power supply and the signal transfer for DL sensors. An additional power supply by means of an external power supply unit (such as with the CAN bus) is not possible.

Programming with TAPPS2 / DL bus

As the DL sensors have a relatively high power demand, the "bus load" must be considered: The bus converter supplies the maximum bus load of 100 %. The bus loads of the DL sensors are

listed in the technical data of each DL sensor. Example: DL sensor FTS4-50DL has a bus load of 25 %. Consequently up to four FTS4-50DL sensors

can be connected to the DL bus.

DL output

Analogue and digital values can be transmitted to the DL bus network via a DL output. For example, a

digital command to activate an O2-DL O2 sensor can be issued. Example: Programming the parameters of DL output 1

Entering the designation Specify the source in the controller

which supplies the value for the DL output. Specify the destination address of the DL sensor to be activated.

Provision has been made for the specification of an index number, but there is not yet any DL bus device which requires that information.

For the activation of the O2 sensor, the index therefore has no effect and can be ignored.

Programming with TAPPS2 / M-Bus

M-Bus

The M-Bus is a master/slave system for reading data from energy and volume meters (electricity, heat, water, gas).

As a master, this bus converter is therefore suitable for the parallel connection of up to four M-Bus meters (slaves).

In total, a maximum of 32 M-Bus values can be read per bus converter. There must only be one

master in the M-bus system. This menu contains all the information and settings needed to set up an M-Bus network.

Settings

In the Device settings / M-Bus menu, the general settings for the M-Bus and the addresses of the M-Bus devices are defined.

Baud rate

The standard baud rate of the M-Bus devices is 2400 Bd. The factory setting does therefore not usually need changing.

Interval time

The readout intervals can be adjusted from 10 seconds to 2 days. Longer intervals use up less battery life in battery operated M-Bus meters.

M-Bus device 1-4

For every connected M-Bus device, enabling must be set to "Yes" and the primary slave address must be entered (between 0 and 250). The primary slave address is set at the M-Bus device in accordance with the manufacturer's instructions. The same slave address cannot be used twice in the M-Bus network.

Programming with TAPPS2 / M-Bus

M-Bus input

Up to 32 M-Bus inputs can be programmed. For a connected M-Bus device, device information and data received can be read by pressing the

"List" button. Example: C.M.I. view for a connected M-Bus meter

After 255 access attempts, the access number is reset to

Programming with TAPPS2 / M-Bus

Device information

Information about the device and manufacturer is shown at the top. The item "Data type" also enables "Device information" to be selected, in order to read out data such as the identification number or device type.

Received data

Up to 128 values per meter can be shown here. The order is defined according to the telegram address and the start byte. In addition, the value read is shown with the unit.

Example: Value 2 comes from telegram address 1 and start byte 26. Values 3 and 4 both relate to byte 34, but with different units.

The manuals issued by the M-Bus device manufacturers contain more details about the values.

Example: Programming the parameters of M-Bus input 1

Available for selection: Analogue or digital

In most cases, analogue (numeric) values are applied.

General

Device: Entry of the device number as per the device settings (1-4) Value number: Entry of the value number from the "List" of device information read (C.M.I. menu M-

Bus settings)

Divisor / factor: Entry of a divisor or factor to adjust the value read to the actual quantity (e.g.

correct positioning of the decimal point).

Designation

Every M-Bus input can be given its own designation. The designation can be selected from various designation groups or can be user defined. In addition, up to 16 index numbers can be issued.

Example:

Programming with TAPPS2 / M-Bus

Unit

If the measured variable is set to "Automatic", the unit of measurement specified by the M-Bus device will be applied in the bus converter.

If you select "User def.", you can select a unit of your own, a sensor correction and, if the sensor check is set to active, a monitoring function.

Every M-Bus input is assigned a unit, which can differ from the unit used by the M-Bus device. A wide range of units is available to choose from.

Sensor correction

The value of the M-Bus input can be corrected by applying a fixed differential value.

Value at timeout

This setting is only displayed if the measured variable is set to "User def.". This application is not yet available.

Sensor check

If you set the sensor check to "Yes", the sensor error of the M-Bus value is available as a digital input variable for a function.

This application is only useful if user defined threshold and output values are specified for the sensor error.

Sensor error

This setting is only displayed if the measured variable is set to "User def." and the sensor check is active.

Sensor error: Status "No" for a correct value within the threshold values and "Yes" for a value outside

the thresholds. This allows the controller to react to the failure of an M-Bus device, for example.

In order to make good use of the sensor check, the short circuit and lead break thresholds should be changed from "Standard" to "User defined" and the required threshold values defined. The required short circuit and lead break values will subsequently also be defined by the user.

If the measurement read is below the defined short circuit threshold or exceeds the lead break threshold, the relevant output values will be applied instead of the measurement.

Programming with TAPPS2 / M-Bus

By selecting suitable thresholds and output values, a fixed value can be specified for the bus converter in the event of a measurement failure, to allow a function to continue operating in emergency mode (fixed hysteresis: 10 or 1.0 °C).

The short circuit threshold must be defined below the lead break threshold. Example: Temperature

If the measurement is below 10 °C, 50 °C will be issued; if it exceeds 100 °C, 70 °C will be issued.

Once the parameter entries have been completed by pressing OK, the M-Bus input in TAPPS2 will look like this:

• Network error DL

Controller start generates a 20 second pulse 40 seconds after the device is switched on or reset, and is used for monitoring the controller starts (e.g. after power failures) in the datalogging feature. The interval time in datalogging should be set to 10 seconds for these starts.

The sensor errors and network errors are global digital values (No/Yes) which are not connected to the error status of a specific sensor or network input.

If any one of the sensors or network inputs has an error, the status of the corresponding group changes from "No" to "Yes"

"Time" system values

"Date" system values

• Second (of the current time)

• Day

These settings are described in the chapters on the relevant bus.

C.M.I. Menu / Date / time / location

C.M.I. Menu

Date / time / location

The Date and Time are shown in the status line at the top right. As the bus converter does not have its own clock function, the time and date are taken from network

node 1 and cannot be changed in the bus converter. A CAN bus device which has its own clock function must therefore have the node number 1 (UVR16x2, UVR1611, RSM610, C.M.I.).

Selecting this status field takes you to the menu for the date, time and location details.

Display example:

The date and time are taken from CAN node 1. Changes made to the date and time in this menu will therefore not be applied permanently.

Loading function data or updating firmware via C.M.I.

In the data admin C.M.I. menu, function data can be loaded or saved and the firmware (the operating system) can be loaded onto the module.

A separate operating system version is required for each language. Consequently, unlike the UVR16x2 controller, the bus converter does not have a menu for language selection.

The required file must first be loaded onto the SD card of the C.M.I. The file is subsequently transferred onto the bus converter.

You can perform these actions by simply dragging the files while holding down the left mouse button ("drag & drop").

Example: Loading function data from the SD card onto the bus converter

Before the data transfer starts, you will be asked to provide meter readings and the expert or technician password for the bus converter.
