PG-103-105-AC is highly powerful, superior, completely configurable and productive Building & Industrial Automation gateway for integrators to effortlessly interface devices to networks in commercial buildings and industrial plants.

PG-103-105-AC Gateway model supports BACnet IP and LonWorks protocols. It is a Bi-directional Converter that can be configured as a Client and/or a Server on either protocol interface.

When configured as a LonWorks client, the PG-103-105-AC can read data from your LonWorks devices and publish it as BACnet IP data. Also, it can write commands sent from the BACnet IP side to the LonWorks devices.

When configured as a BACnet IP client, the PG-103-105-AC can read data from your BACnet IP devices and publish it as LonWorks data. Also, it can write commands sent from the LonWorks side to the BACnet IP devices.

The PG-103-105-AC can be configured to behave as a server on both LonWorks and BACnet IP interfaces. This mode is useful when data exchange is required between a LonWorks client (for eg. SCADA) and a BACnet IP client (for eg. a Building Management System).

The PG-103-105-AC can be configured to behave as a client on both LonWorks and BACnet IP interfaces.

PG-103-105-AC gateways have benefitted system integrators worldwide with its powerful line of gateways. Additionally, PG-103-105-AC gateway runs the same protocol conversion software on a productive and cost efficient platform backed by the experience, engineering expertise and technically proven support that integrators have come to expect from PG-103-105-AC.

Scenario 1

• There is a Controller on site which provides data output on LonWorks.
• The site has a Building Management System on BACnet IP that needs the energy data from Controller.
• A direct exchange of data between Controller and Building Management System is not possible as the LonWorks Controller provides data output on LonWorks and the Building Management System understands BACnet IP only.

Solution

• The devices can directly communicate with each other only if they are on the same protocol. LonWorks is a Serial Protocol while BACnet IP is an Ethernet based Protocol. Hence, a converter is needed which will convert the data from BACnet IP device to LonWorks and vice versa.
• PG-103-105-AC BACnet IP to LonWorks converter is an excellent solution to this requirement. This helps the gateway in reading the data from the Controller on LonWorks and it caches this data internally and then provides it on BACnet IP when requested from Building Management System.

Scenario 2

• There are Thermostats on the site which provide data output on BACnet IP.
• The site has a PLC on LonWorks which needs the temperature data from thermostat on BACnet IP.
• A direct exchange of data between Thermostat and PLC is not possible as the thermostats provide data output on BACnet IP and PLC understands LonWorks only.

• The devices can directly communicate with each other only if they are on the same protocol. LonWorks is a Serial Protocol while BACnet IP is an Ethernet based Protocol. Hence, a converter is needed which will convert the data from BACnet IP device to LonWorks and vice versa.
• PG-103-105-AC BACnet IP to LonWorks converter is an excellent solution to this requirement. This helps the gateway in reading the data from the Thermostats on BACnet IP and it caches this data internally and then provides it on LonWorks when requested from the PLC.

LonWorks

LonWorks (local operation network) is a networking platform specifically created to address the needs of control applications. This platform is created for networking devices over media such as twisted pair, power lines, fiber optics, and RF. It is used for the automation of various functions within buildings such as lighting and HVAC see building automation.

There are two physical-layer signaling technologies, twisted pair “free topology” and power line carrier, are typically included in each of the standards created around the LonWorks technology. The two-wire layer operates at 78 Kbit/s using differential Manchester encoding, while the power line achieves either 5.4 or 3.6 Kbit/s, depending on frequency.

Additionally, the LonWorks platform uses an affiliated Internet protocol (IP) tunneling standard in use by a number of manufacturers to connect the devices on previously deployed and new LonWorks platform-based networks to IP-aware applications or remote network-management tools. Many LonWorks platform-based control applications are being implemented with some sort of IP integration, either at the UI/application level or in the controls infrastructure.

BACnet IP

The BACnet/IP allows users to transfer data to and from devices over Ethernet using BACnet/IP Protocol. It allows users to use different applications to discover devices, objects and properties of objects of any field device that supports BACnet IP.

Like the Control and Information Protocol (CIP) used in industrial application, BACnet uses objects to represent data on a network. Objects defined by the BACnet specification include Analog Input, Analog Output, Analog Value, Binary Input, Binary Output, Binary Value, Multi-State Input, Multi-State Output, Calendar, Event-Enrolment Program, Schedule, Command, and Device.

The BACnet protocol is a completely non-proprietary open communication software standard. The standard is now controlled by the ANSI (American National Standards Institute) and ASHRAE (American Society of Heating Refrigeration and Air-Conditioning Engineers) Standard 135- 1995. In June of 1995, ASHRAE adopted BACnet as a standard for the Building Automation industry.

• We will configure the gateway for you based on your requirement and support you during commissioning of the gateway, so you do not have to worry about configuring the PG-103-105-AC gateway.
• However, it is very helpful to know how to configure the devices. All the required tools and supporting product manuals with be provided completely free of cost with your purchase.
• Configuration of the PG-103-105-AC is done using a ‘.csv’ file. This file can be edited using any text editor (example Microsoft excel).
• In this file we need to enter information for the Client and Server side interfaces of the PG-103-105-AC. This includes but is not limited to

1. Node ids of the slave devices
2. IP addresses/device address of the slave devices
3. Baud rate, parity, stop bits for serial communication
4. Scan rates

• And finally we need to create an internal mapping that would map each data value read on the client side to a data value on the server side.
• For detailed information on configuration please get in touch with us and review the configuration manual on top of this page.
