IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Description Introduction This document describes the integration of BACnet MSTP and BACnet IP installations into Modbus RTU or Modbus TCP compatible devices and systems using the Intesis Modbus Server – BACnet Client gateway. The aim of this integration is to make accessible BACnet system signals and resources from a Modbus based control system or device, as if it was a part of the own Modbus system and vice-versa.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Functionality From the BACnet system point of view, after the start up process, Intesis subscribes to configured BACnet points or reads them continuously from their respective BACnet server devices and updates in its memory the value of the present_value property received from them.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 2 BACnet interface This section describes the BACnet part of the Intesis's configuration and functionality. Description BACnet server devices are represented in the form of Devices holding Objects, normally every physical device corresponds to a logical one. The Objects can be of different type depending on the data and functionality the represent: Analog Input, Analog output, Digital Input, etc. Up to 23 different types of objects.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN BACnet/IP Main parameter to set up for BACnet/IP, additional to basic IP settings (IP, netmask, default gateway) is the communication port. Intesis uses port 47808 (0xBAC0) by default and it can be changed at configuration time.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Points definition Every point defined in Intesis has the following BACnet features associated to it: Feature BACnet Device Description BACnet device to which belongs the point, from a list of BACnet devices that can be defined in Intesis (up to 16).
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Modbus functions 03 and 04 (read holding registers and read input registers) can be used to read Modbus registers. Modbus functions 05 and 15 (Single digital Holding Registers and Write Multiple Holding Registers) can be used to write Modbus registers. Modbus functions 06 and 16 (Single Multiple Holding Registers and Write Multiple Holding Registers) can be used to write Modbus registers.

Error comm One of the following Modbus function codes can be used: • • • • • • • • 1- Read Coils. 2- Read Discrete Inputs. 3- Read Holding Registers. 4- Read Input Registers. 5- Write Single Coil. 6- Write Single Register. 15- Write Multiple Coils. 16- Write Multiple Registers.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 4 Connections Find below information regarding the Intesis connections available. Power Supply Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated power supply. If using DC power supply: Respect polarity applied of terminals (+) and (-). Be sure the voltage applied is within the range admitted (check table below). The power supply can be connected to earth but only through the negative terminal, never through the positive terminal.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Powering the device A power supply working with any of the voltage range allowed is needed (check section 6). Once connected the RUN led (Figure above) will turn on. WARNING! In order to avoid earth loops that can damage the gateway and/or any other equipment connected to it, we strongly recommend: • • The use of DC power supplies, floating or with the negative terminal connected to earth.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 4.3.2 BACnet MSTP Connect the EIA485 bus to connectors A3 (A-), A4 (B+) and A1 or A2 (SNGD) of gateway’s PortA. Respect the polarity. Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. Set port switch SW1 to ON if gateway is installed on one bus end.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 5 Set-up process and troubleshooting Pre-requisites It is necessary to have a Modbus TCP client or Modbus RTU master operative and well connected to the corresponding Modbus port of Intesis as well as the BACnet IP or BACnet MSTP server devices connected to their corresponding ports as well. Connectors, connection cables, PC to use the configuration tool and other auxiliary material, if needed, are not supplied by HMS Industrial Networks S.L.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 5.2.3 Configuration tab Select the Configuration tab to configure the connection parameters. Three subsets of information are shown in this window: General (Gateway general parameters), Modbus Slave (Modbus interface configuration) and BACnet Client (BACnet interface parameters). Figure 5.2 Intesis MAPS configuration tab General and Modbus Slave tabs are explained in Intesis MAPS user manual for Intesis Modbus Server Series. 5.2.3.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Configuration for BACnet client has three sections: General Configuration, Devices Configuration and Gateway Mode. • General Configuration In this section, following parameters should be configured: 1. Device Name. Name of the device in the bacnet network (‘object name’ property of device object) 2. Device Instance. Instance number of the device in the bacnet network (instance number property of device object) 3. Password.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN Figure 5.4 Devices configuration section Devices can be added in three ways: • Manually: With checkbox ‘Use template’ disabled, Add button should be clicked. Number of devices to add can be adjusted in the text field next to button Add. • From template: Same as manual but based on a template file. This will add in Signals table all the signals specified in the template file for the device to be integrated.

(Recipient type: Address (MAC)) MSTP MAC Address: MAC address 0..255 of the BACnet server device. 8. Reading type: Related to service that will be used to read the BACnet server device. Options are Polling (ReadProperty), COV, COV-unconf (unconfirmed COV), Polling Multiple (ReadPropertyMultiple). 9.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN In top section of the window BACnet Explorer Configuration, following parameters are available: • Explore Mode: It can be either IP or MSTP, depending on last configuration downloaded to Intesis. ! • NOTE: Bacnet Explorer function will use or BACnet exploration actual parameters for BACnet configured in Intesis. This is, values for Link layer (IP or MSTP), Device Object Instance, MAC & baud rate or IP address, etc.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN By clicking each of the devices, its Device Name, Instance, Network Number and Vendor Id will be given in the center of the dialog. Once list of devices is shown, next step is obtaining their list of objects. This can be done in two ways: • Selecting a particular device and clicking at Discover button • Checking all devices whose objects are to be scanned and clicking at Discover Checked Devices button.
IntesisTM Modbus Server – BACnet Client • • User Manual r1.3 EN Device INBACSAM---O000 (200) Device INBACDAL---0000(246) The BACnet objects that will be integrated in configuration are O01U00_Setpoint_S and O01U00_Room_Temperature for Device INBACSAM---O000, and those selected for Device INBACDAL---0000(can be seen when device is selected in the list at the left part of the window). Next step is to transfer those objects to MAPS configuration.
IntesisTM Modbus Server – BACnet Client User Manual r1.3 EN 5.2.5 Sending the configuration to Intesis When the configuration is finished, follow the next steps. 1.- Save the project (Menu option Project->Save) on your hard disk (more information in Intesis MAPS User Manual). 2.- Go to tab ‘Receive / Send’ of MAPS, and in Send section, press Send button. Intesis will reboot automatically once the new configuration is loaded. Figure 5.
