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

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
8 (0x08)	Diagnostics	Check Modbus communication
16 (0x10)	Write Multiple Registers	Write several consecutive registers
43 (0x2B)	Read Device Identification	Read identification data for the device
14 (0x0E)	Read Device Identification	Read identification data for the device

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.
