Chapter 1 Corrigo with EXOline, Modbus and BACnet communication Introduction Corrigo ventilation is a pre-programmed application for control of an air handling unit. The Corrigo controller can be used either stand-alone or integrated in an existing EXO project. In both cases, it is configured via the display or by using the configuration tool E tool© on a PC. This document describes all signals that are accessible via EXOline, Modbus and BACnet. It does not describe how to create an EXO project.
Baudrate 150, 300, 600, 1200, 2400, 4800, 9600 BACnet communication Corrigo is capable of communication via the BACnet-AAC (Advanced Application Controller) protocol, using either IP or MS/TP data link formats. A B-AAC unit is a device that may be intended for a specific application, but which supports some degree of programmability allows the user to do more – such as generate alarms, definine schedules, synchronize clocks, etc.
Device name CorrigoVentilation BBMD address Device ID low 2640 Device ID high 0 (x10000) 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.
BACnet MS/TP Configuration Upon delivery, the BACnet MS/TP protocol is disabled as a default. To enable BACnet communication, the function must first be activated.
BACnet in E tool© Addressing The below picture illustrates the appearance of BACnet addressing in E tool©: BACnet/IP = Activation status of BACnet/IP protocol. BACnet device name = The name of the device. The device ID is devided into two parts, one low and one high. For example: If the high part of the ID would be “1”, then the device ID above would be “00012640”. BACnet device ID low = The lower part of the device identification.
Visualised example The simplified example below visualises the Master/Slave relation. In addition to the figure, checksums for message validation are also transmitted in both query and answer.
Chapter 2 System integration using Modbus Configuration The communication parameters for the Modbus line is the most important thing to configure first. As described earlier, these parameters must be identical in both the master unit and slave units, since they define the structure of messages and the transmission speed. The default configuration values of a Corrigo controller are shown in the figure below. Corrigo is set to Slave Address 1 as a default.
Reading values An effective way to read values is to read multiple variables simultaneously. To, for example, read all analogue outputs, set the Modbus query to the values shown in the figure below. The first analogue output variable starts at address 54 (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.
