PG-104-105-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-104-105-AC Gateway model supports JCI Metasys N2 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-104-105-AC can read data from your LonWorks devices and publish it as JCI Metasys N2 data. Also, it can write commands sent from the JCI Metasys N2 side to the LonWorks devices.

When configured as a JCI Metasys N2 client, the PG-104-105-AC can read data from your JCI Metasys N2 devices and publish it as LonWorks data. Also, it can write commands sent from the LonWorks side to the JCI Metasys N2 devices.

The PG-104-105-AC can be configured to behave as a server on both LonWorks and JCI Metasys N2 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).

PG-104-105-AC can be configured to behave as a client on both LonWorks and JCI Metasys N2 interfaces.

PG-104-105-AC gateways have benefitted system integrators worldwide with its powerful line of gateways. Additionally, PG-104-105-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-104-105-AC.

Key Features

  • Ability to interface up to 1000 points of common BAS protocols
  • 1xLonWorks FTT10 port, 1xRS485 Port, 1xEthernet port
  • BTL Mark – PG-10XX Series
  • LonMark Certified – PG-10XX Series
  • BACnet COV support for fast data communication while reducing traffic over a BACnet network
  • Capacity of 1000 LonWorks network variables – almost 5 times more than competition – PG-10XX Series
  • Multi-configuration capability; specific configurations selectable via DIP switches or software
  • Flat panel mount standard, DIN rail mount option
  • DIP switches to select baud rate or node ID on the fly

Scenario 1

  • There are several Cummins PCC controllers on various diesel Generators the site which provide data output on LonWorks.
  • The site has a Network Automation Engine on Metasys N2 that needs energy data from the Controller.
  • A direct exchange of data between Controllers and Engine is not possible as the Controllers provide data output on LonWorks and an Engine understands Metasys N2 only.

Solution

  • The devices can directly communicate with each other only if they are on the same protocol. LonWorks and Metasys N2 are Serial based Protocol. Hence, a converter is needed that can convert the data from Metasys N2 device to LonWorks and vice versa.
  • PG-104-105-AC Metasys N2 to LonWorks converter is an excellent solution to this requirement. This helps the gateway in reading the data from the PCC controller on LonWorks and it caches this data internally and then provides it on Metasys N2 when requested from the Network Automation Engine.

Scenario 2

  • There are controllers on the other site which provide data output on Metasys N2.
  • The site has a PLC on LonWorks that needs the temperature data from controllers on Metasys N2.
  • A direct exchange of data between controllers and PLC is not possible as the controllers provide data output on Metasys N2 and PLC understands LonWorks only.

Solution

  • The devices can directly communicate with each other only if they are on the same protocol. LonWorks and Metasys N2 are Serial based Protocol. Hence, a converter is needed that can convert the data from Metasys N2 device to LonWorks and vice versa.
  • PG-104-105-AC Metasys N2 to LonWorks converter is an excellent solution to this requirement. This helps the gateway in reading the data from controllers on Metasys N2 and it caches this data internally and then provides it on LonWorks when requested from the PLC.

Outline of Metasys N2 and LonWorks

Metasys N2

Metasys N2 was developed by Johnson Controls as a network to interface their various devices and controllers. It is on the physical layer RS-485 set of data communications standards and supports 9600 baud, 8 data bits, and no parity and in half-duplex mode only. This network supports communications with a huge range of devices manufactured by Johnson Controls and some other companies. Metasys N2 by Johnson Controls is a master/slave protocol with one master only so it is not possible to have two devices performing this function on the same network.

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.

How to configure the PG-106-105-AC gateway?

  • 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-106-105-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-106-105-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-106-105-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.
