2. Configuration
2.1 Network description
The network used for this module is conditionally compliant (implementation class = basic) with the MODBUS over serial line two-wire RS-485 interface. The module uses the RTU transmission mode. Devices are connected directly to the network, i.e. daisy chained. The network uses line polarization and line termination at both ends.
These guidelines depend on the environmental conditions and the physical network characteristics: · Maximum cable length of 1200 metres without repeater · 32 devices pr. master / repeater (a repeater counts as a device)
The modules uses an auto baud rate scheme that depends on the byte error ratio. If the error ratio exceeds a limit, the baud rate is changed. This means that all devices in the network must use the same communication settings, i.e multiple communication settings are not allowed. The module can operate with either 19200 (default) or 38400 baud network baud rate, 1 start bit, 8 data bits, even parity and one stop bit (11 bits). The valid address range is 1 247.
For specific details, please consult the specifications · Modbus Application Protocol V1.1a. · MODBUS over Serial Line, Specification & Implementation guide V1.0 both of which can be found on http://www.modbus.org/

SCADA system: Connected via Danfoss MODBUS OPC server

3. General parameter description
3.1 Parameter naming
The parameters are divided into some functional sections, the main parts being the control parameter and schedule parameters. The complete parameter list can be found in the appendix.
All parameters correspond to the MODBUS term "holding register" (or "input register" when read-only). All parameters are therefore read/write accessed as one (or more) holding/input registers independently of data type.

3.2 Control parameters
The user interface parameters are located in the address range 11000 13999. The 1000th decimal indicates the ECL Comfort circuit number, i.e. 11xxx is circuit I, 12xxx is circuit II and 13xxx is circuit III.
The parameters are named (numbered) in accordance with their name in the ECL Comfort. A complete list of the parameters can be found in the appendix.

3.3 Schedules
The ECL Comfort divides the schedules into 7 days (17), each consisting of 48 x 30-minute periods.

The week schedule in circuit III has only one day. A maximum of 3 comfort periods can be set for each day.
Rules for schedule adjustment 1. The periods must be entered in chronological order, i.e. P1 ... P2 ... P3. 2. Start and stop values must be in the range 0, 30, 100, 130, 200, 230, ..., 2300, 2330, 2400. 3. Start values must be before stop values if the period is active. 4. When a stop period is written to zero, the period is automatically deleted. 5. When a start period is written different from zero, a period is automatically added.
3.4 Mode and status
The mode and status parameters are located within the address range 4201 4213. The mode can be used to control the ECL Comfort mode. The status indicates the current ECL Comfort status.

If one circuit is set to manual mode, it applies to all circuits (i.e. the controller is in manual mode).
When the mode is changed from manual to another mode in one circuit, it also applies to all circuits in the controller. The controller automatically reverts to the previous mode if the information is available. If not (power failure / restart), the controller will revert to the default mode of all circuits which is scheduled operation.
If standby mode is chosen, the status will be indicated as setback.

Operating mode Manual operation Scheduled operation Constant comfort temperature Constant setback temperature Standby

3.5 Time and date
The time and date parameters are located in the address range 64045 64049.

When adjusting the date it is necessary to set a valid date. Example: If the date is 30/3 and must be set to 28/2, it is necessary to change the day first before changing the month.

3.6 Heat meter data
When an ECA 73 with heat meters (only when connected by M-Bus) is installed, it is possible to read the following values*. · Actual flow · Accumulated volume · Actual power · Accumulated energy · Flow temperature · Return temperature
For detailed information please consult the ECA 73 instructions and the appendix.
* Not all heat meters supports these values

3.7 Special parameters
The special parameters include information about types and versions. The parameters can be found in the parameter list in the appendix. Only the ones with a special encoding/decoding are described here.
Device version Parameter 2003 holds the device version. The number is based on the ECL Comfort application version N.nn, encoded 256*N + nn.
ECL Comfort application Parameter 2108 holds the ECL Comfort application. The 2 last digits indicate the application number, and the first digit(s) the application letter.

Value 0

Letter A

Example: 237, letter 2 = C and the number is 37 so the application is a C37.

4 Good behaviour in designing a district heating MODBUS network
In this chapter some basic design recommendations are listed. These recommendations are based on communication in heating systems. This chapter is built as an example of a network design. The example can vary from a specific application. The typical requirement in heating systems is to get access to a number of similar components and to be able to make a few adjustments. The illustrated performance levels might decrease in real systems.
In general it can be said that the network master controls the performance of the network.

4.1 Considerations before implementing communication
It is very important to be realistic when network and performance are specified. Some considerations have to be made in order to secure that important information is not blocked because of a frequent update of trivial information. Keep in mind that heating systems typically have long time constants, and hence can be polled less frequent.

4.2 Basic needs for information in SCADA systems
The ECL Comfort controller can support a network with some pieces of information concerning a heating system. It might be a good idea to consider how to split up the traffic that these different information types generate.

· Alarm handling: Values that are used to generate alarm conditions in the SCADA system.

· Error handling: In all networks errors will occur, error means time out, check of sum error, retransmission and extra traffic generated. The errors might be caused by EMC or other conditions, and it is important to reserve some bandwidth for error handling.

· Data logging: Logging of temperature etc. in a database is a function which typically is non-critical in a heating system. This function must normally run all the time "in the background". It is not recommended to include parameters such as set-points and other parameters that require user interaction to change.

· Online communication: This is a direct communication with a single controller. When a controller is chosen (e.g. service picture in a SCADA system) the traffic to this single controller is increased. Parameter values can be polled frequently in order to give the user fast response. When the online communication is no longer needed (e.g. leaving the service picture in a SCADA system), the traffic must be set back to the normal level.

· Other devices: Do not forget to reserve bandwidth for devices from other manufacturers and future devices. Heat meters, pressure sensors, and other devices have to share the network capacity.

The level for different kinds of communication types must be considered (an example is given in figure 4.2a).

4.3 Final number of nodes in the network
At start-up the network has to be designed with due consideration to the final number of nodes and the network traffic in the network.
A network with a few controllers connected might run without any bandwidth problems at all. When the network is increased, however, bandwidth problems might occur in the network. To solve such problems, the amount of traffic has to be decreased in all controllers, or extra bandwidth can be implemented.

4.4 Parallel network
If a large number of controllers are used in a limited area with a limited length of the communication cable, parallel network might be a way to generate more bandwidth.
If the master is located in the middle of the network, the network can easily be split-up into two and the bandwidth can be doubled.

4.5 Bandwidth considerations
The ECA 71 is based on a command/query and response, meaning that the SCADA system sends a command/query and the ECA 71 responses to this. Do not attempt to send new commands before the ECA 71 has send the latest response or the timeout expires.
In a MODBUS network it is not possible to send commands/queries to different devices at the same time (except broadcast). One command/query response must be completed before the next can be started. It is necessary to think about the roundtrip time when designing the network. Larger networks will inherently have larger roundtrip times.
If multiple devices must have the same information, it is possible to use the broadcast address 0. Broadcast can only be used when no response is necessary, i.e. by a write command.

4.6 Update rate from the ECL Comfort controller
Values in the module are buffered values. The value update times depend on the application.

The following is a rough guideline:
Parameter type Control parameters Schedule Mode Output Time & date M-Bus (actual values) M-Bus (accumulated values)

Update time (approx.) All parameters, once every 10 seconds One day, once a minute Once every 15 seconds Once every 5 seconds Once every 30 seconds Once every 60 seconds (1 minute) Once every 300 seconds (5 minutes)

These update times indicate how often it is reasonable to read values from the different categories.

4.7 Minimize the copy of data in the network
Minimize the number of copied data. Adjust the poll time in the system to the actual need and the data update rate. It makes little sense to poll time and date every second when they only are updated once or twice every minute from the ECL Comfort controller.

4.8 Network layouts
The network must always be configured as a daisy chained network, see the three examples from a very simple network to more complex networks below.

Fig. 4.8a illustrates how termination and line polarization must be added. For specific details, consult the MODBUS specifications.
