1. GENERALITIES

1.1 Introduction

The heat recovery units with PRO-REG controller include an application pre-programed that allows the control of the Heatrecoveryunit.TheconfigurationisdoneviathedisplayorbyusingtheconfigurationtoolEtoolonPC.Thisdocu-ment describes the signals available via Modbus.

1.2 Modbus signals types

All signals accessible from a SCADA system are described further in this document. Signals with a default value are settings that can be changed via a SCADA system. Signals without a default value are actual values which cannot be changed using a SCADA system.

The Modbus type of the signals:1 = Coil Status Register (function Modbus = 1, 5 and 15)2 = Input Status Register (function Modbus = 2)3 = Holding Register (function Modbus = 3, 6 and 16)4 = Input Register (function Modbus = 4)

Supported Modbus functions:1 = Read Coils2 = Read Discrete Input3 = Read Holding Register4 = Read Input Register5 = Write Single Coil6 = Write Single Register15 = Write Multiple Coils16 = Write Multiple Registers

Max. 47 registers A maximum of 47 registers can be read in one message.

Communication limitations

The Modbus master must wait for a minimum of 3.5 character times (4 ms at 9600 bps) between two messages. When the Modbus master communicates with more than one controller on the same communication line (RS485), the Modbusmastermustwaitforaminimumof14charactertimes(16msat9600bps)betweentheanswerandthefirstquestion for the next controller.

2 3

The controller is limited to10 fast communications every 30 seconds. Any other communications will have a delayed answer time of approximately 1 second.

Scale factor Modbus

Realsignalshavescale factor10,except for the timesettingsignalswhichhavescale factor100,and theairflowsignals which have scale factor 1 for Modbus communication. Integer, Index and Logic always have scale factor 1.

A protocol like Modbus consists of several layers (OSI-model). The bottom layer is always the physical layer; the number of wires and signal levels. The next layer describes the communication digits (number of data bits, stop-bits, parityetc).NextarethelayersdescribingtheModbus-specificfunctions(numberofdigitspermessage,themeaningof different messages, etc.).

RS485 is the electric part of the protocol or physical layer. The RS485 protocol has two connections, A and B. Often there is also a ground (N).The RS485 connection is: A -> A and B -> B. The RS485 protocol is called “half duplex”: indeed the communication can not make in one direction at a time, ie d. the master device sends a request and then waits for a reply. A and B are used both for transmission and for reception.

2. INTEGRATION SYSTEM WITH MODBUS

2.1 Configuration

Corrigo is set to Slave Address 1 as a default. If more units are added, a new Modbus address can be set for each unit using the Corrigo display or E tool.

2.2 Transmission model

Corrigo uses the RTU transmission mode; not to be confused with the ASCII mode in the settings.The settings for the transmission mode must be the same in the master unit and the slave units, since Modbus/RTU cannotunderstandModbus/ASCIImessages.Theconfigurationparameterwordlengthisalways8forModbus/RTU.

2.3 Writting values

To override the Corrigo output values, set the output to manual mode using a Modbus signal. Then set the corresponding ..._anSet signal to the wanted level. These signals are listed in Chapter 5: Holding Registers.Rememberthatonlyvalueswithadefaultvalueareadjustable,youwillfindtheseinthechaptersCoilStatusRegisterand Holding Register.

2.4 Reading values

An effective way to read values is to read multiple variables simultaneously. To, for example, read all analogue outputs, settheModbusquerytothevaluesshowninthefigurebelow.Thefirstanalogueoutputvariablestartsataddress54(QAnaOut.AQ1). To read address 54 to 58, set the length to 5. The Modbus answer will then communicate all 5 values in just one message, making the communication more effective.

3. INTEGRATION IN BACNET SYSTEMS

3.1 BACnet communication

Corrigo is capable of communication via the BACnet protocol, using either IP or MS/TP data link formats. In order to connect a Corrigo running a ventilation application to a BAS (Building Automation System) via BACnet/IP, a third gene-ration Corrigo with a TCP/IP port is required. To connect to a BAS via BACnet MS/TP, a third generation Corrigo with a second RS485 communication port is required.

BACnet typeThe BACnet type of signals:10XXX = Read and write binary20XXX = Read binary30XXX = Read and write analogue40XXX = Read analogue30XXX = Read and write multistate40XXX = Read multistate

(Where XXX = Modbus address)

NOTE: In the variable lists contained in this manual, the following abbrevations are used:AV = Analogue ValueBV = Binary ValueMSV = Multistate Value

BACnet object names are the same as for EXOL type objects, but are shortened by removing the preamble “Cor_” (e.g.: “VentSettings.Cor_OverHeatFastStop” becomes “VentSettings.OverHeatFastStop”, etc.).

3.2 BACnet/IP configuration

Upon delivery, the BACnet/IP protocol is disabled as a default. To enable BACnet communication, simply change the setting “Not active” to “Active”. The protocol will now be available for use:

Device name This is the devices name that is shown on the BAS when a device is discovered.

BBMD address

The BBMD address (BACnet/IP Broadcast Management Device) is used for discovering devices that are attached to different BACnet/IP subnets and separated by an IP router. The address is entered as host:port, where “host” can be the host’s name if DNS is configured. If DNS is not configured, the host address should be entered in the format “xxx.xxx.xxx.xxx”, followed by the port number (default setting 47808).

Example: mybbmd:47808 (with DNS configured) or 10.100.50.99:47808

Device ID

The ID of a device, used to identify it on the BACnet network. This number cannot be duplicated anywhere on the BACnet network and must therefore be unique. To set an ID value of 34600, the low number would be set to 4600 and the high number to 3.

DHCP

The Dynamic Host Configuration Protocol (DHCP) is a network protocol used on Internet Protocol (IP) networks for dynamic distribution of network configuration parameters, such as IP addresses, DNS servers and other services. The Corrigo can be configured to either obtain an IP address from a DHCP server (dynamic) or the address can be set manually (static). If you wish to set a static IP address for the Corrigo, simply enter the IP address you wish to use along with the subnet mask, gateway address and DNS server address:
