Chapter 1 Introduction Corrigo ventilation Corrigo ventilation is a pre-programmed application for control of an air handling unit. The Corrigo controller can either be used stand-alone or integrated in an existing EXO project, in both cases it is © configured via the display or using the configuration tool E tool on a PC. About this manual This document provides an introduction to communication via Modbus, BACnet and EXOline and contains a list of commonly used signals. This list is found in chapter 3.
Chapter 2 Signal types and functions Signal 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. EXOL type The EXOL type of signals: R = Real (-3.3E38 - 3.
Supported Modbus functions: 1 = Read Coils 2 = Read Discrete Input 3 = Read Holding Register 4 = Read Input Register 5 = Write Single Coil 6 = Write Single Register 15 = Write Multiple Coils 16 = Write Multiple Registers BACnet type The BACnet type of signals: 10XXX = Read and write binary 20XXX = Read binary 30XXX = Read and write analogue 40XXX = Read analogue 30XXX = Read and write multistate 40XXX = Read multistate (Where XXX = Modbus address) 6 Signal types and functions Communication guide
