Functional description

Expansion module EM-IP is used to integrate EASYLAB controllers Type TCU3 or EASYLAB adapter modules Type TAM into an IP-based network and connect them to the central BMS using the BACnet/IP or Modbus/IP protocol.

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.

BACnet/IP mode and the webserver allow for trend logging, alarming and scheduling for selected data points. The integral microSD card is used for trend logging. The integral webserver is used to configure EM-IP, to access trend logs and event logs, and to enter controller data using the web UI.

The optional real time clock (RTC) expansion module can be used for trend logging or event logging if, for example, EM-IP is not integrated with a network of if no time server is available in the network.

Modbus interface

Application

EM-IP 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

Modbus functions

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

Input variables

Mode

BMS access: WR RD

Equipment functions: FH, RR with RMF, TAM with RMF


Function

  • FH: Operating mode default setting for a single fume cupboard controller, only with individual operating mode default setting (stand-alone operation)
  • RMF: Operating mode default setting for the entire EASYLAB room
  • The valid binding of the input variable results in a valid operating mode default setting via BACnet or Modbus
  • The invalid binding of an input variable or failure to set an operating mode default results in no operating mode default being set for the EASYLAB controller or room
  • Which operating mode is then used depends on the default options available on the controller


Functional values (BACnet / Modbus)

  • 1/0 = No default: The central BMS does not default an operating mode for the controller or room. The operating mode is set locally, e.g. on the room control panel, on the fume cupboard control panel, or using switch contacts. If the operating mode is not set locally, the controller activates standard mode.
  • 2/1 = Standard mode: Normal operation in the daytime (in Germany: usually according to DIN 1946, part 7, 25 m³/h extract air per m² main useful floor area)

Installation and commissioning

Installation

  • As attachment for the EASYLAB base component: factory mounted
  • For retrofitting: Mount the expansion module into the base casing


Commissioning

  • The EASYLAB controller identifies the expansion module automatically
  • Use the Ethernet patch cable to connect the configuration computer with an active DHCP client or adapted IP address to the EM-IP module
  • Complete and save the configuration using the personal computer and the web UI
  • Restart EM-IP using the Reset push button or web UI and connect it to the target network (BACnet/IP, Modbus/IP or Ethernet network)
