Functional description

The expansion module EM-BAC-MOD is used to integrate EASYLAB controllers Type TCU3 or EASYLAB adapter modules Type TAM into a BACnet (MS/TP) network and in this way connect them to the central BMS.

The BACnet or Modbus interface supports the EASYLAB room operating mode concept. It is possible to set operating mode defaults in order to control different volume flow rates for daytime and night-time operation; it is also possible to increase or reduce the air change rate (volume flow rate setpoint change), e.g. to influence the room temperature.

Using the BACnet or Modbus interface, an individual alarm management system can be set up by consolidating configurable EASYLAB alarms. The interface also enables the transfer of actual operating values such as volume flow rates and damper blade position for a controller or for all controllers in a room.

Modbus interface

Application

The expansion module EM-BAC-MOD supports the following interface functions on an EASYLAB controller TCU3 or an adapter module TAM if the Modbus protocol has been selected:

  • Modbus is an open serial master-slave communication protocol which has become a de facto standard for the industry
  • The master (e.g. central BMS) can address a number of slaves (EASYLAB volume flow controllers) and use Modbus functions to request information from individual data points
  • Data access is based on numbered data registers which the master has to define in order to request data using Modbus functions
  • The slave responds by either returning the requested information or an exception code (error)
  • Example: The Read Holding Registers function (register no. 3) returns the volume flow rate actual value of the addressed controller
  • General information for a Modbus device can be read out using the Read Device Identification function

Data points – detailed description

The following is a detailed description of the information that each data point provides; input variables and output variables are described separately:

  • Name of data point
  • Access as viewed from the central BMS
  • WR – Defaults for the volume flow controller or room, from the central BMS
  • RD – Data provided by the volume flow controller or room
  • List of volume flow controller equipment functions for which the variable is available
  • Unit of measure (applies only to BACnet objects of type Analogue Value Object)
  • Function and special functional values with their meaning
  • Access to the data point using a BACnet object or Modbus register

Installation details

  • Installation details

Installation and commissioning

Installation

  • As attachment for the EASYLAB base component: factory mounted
  • For retrofitting: Mount the expansion module into the base casing
  • Make connection to the BACnet/Modbus EIA-485 network


Commissioning

  • The EASYLAB controller identifies the expansion module automatically
  • Select BACnet or Modbus protocol using slide switch
  • Set network address and communication parameters using the coding switches
  • If necessary, activate terminal resistor of the network segment
  • Integrate data interface with the central BMS (system integration)
