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.

Expansion module to supplement an EASYLAB base component (controller TCU3 or adapter module TAM) with a BACnet/IP or Modbus/IP interface to link rooms or individual volume flow controllers to the central BMS.

Expansion module includes an interface for IP-based networks; switching between BACnet/IP and Modbus/IP is possible. All settings for alarming, trend logging, event logging, notifications and scheduling can be accessed and changed using the integral webserver.

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

Function no.	Designation	Meaning
1 (0x01)	Read Coils	Read states of 1 to 8 bits according to bit list
3 (0x03)	Read Holding Registers	Read several consecutive registers
4 (0x04)	Read Input Registers	Read several consecutive registers
5 (0x05)	Write Single Coil	Write state of a single bit
6 (0x06)	Write Single Register	Write single register

Exception codes

Codes	Designation	Meaning
1	Illegal Function Code	Unknown function or subfunction code
2	Illegal Data Address	Invalid register address
3	Illegal Data Value	Inconsistent coding for number of registers/bytes, data value

Exception codes (error codes) are returned in case of invalid function or register access.

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)
3/2 = Reduced operation: Low mode in comparison to standard mode, e.g. as a night-time setback
4/3 = Increased operation: High mode in comparison to standard mode, e.g. in an emergency
5/4 = Shut-off: Shut-off of the volume flow controller, e.g. to save energy at night or to shut down the system
6/5 = OPEN position: Open position of the volume flow controller

The Device_ID_* data points (0 – 23) of the EM-IP expansion module contain the Device ID of each controller (1 – 24)
Controllers are automatically assigned a Device ID as part of the configuration procedure
Controllers are automatically assigned to the data points
If any variables, e.g. VolflowAct_* and LocalAlarm_* or others, have the same slot (*), they are associated with the same controller, which is being addressed

Example

A controller has Device ID 5
When you switch on the supply voltage, the expansion module assigns a free slot to that device, let's say slot 8
As a consequence, Device_ID_8 will receive value 5, and the VolflowAct_8 and LocalAlarm_8 variables will receive the current values for controller 5
