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

The PG-104-105-AC can be configured to behave as a server on both SNMP and JCI Metasys N2 interfaces. This mode is useful when data exchange is required between a SNMP 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 SNMP 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
  • 2xRS 485 Ports, 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
  • 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 Metasys N2 Controllers on the site which provide data output on Metasys N2.
  • The site has a SCADA on SNMP that needs the data from the Ion meters on Metasys N2.
  • The direct exchange of data between Controllers and SCADA is not possible as the Controllers provide data output on Metasys N2 and SCADA understands SNMP only.

Solution

  • The devices can directly communicate with each other only if they are on the same protocol. Metasys N2 is a Serial protocol, while SNMP is an Ethernet protocol. Hence, a converter is needed that converts the data from SNMP device to Metasys N2 and vice versa.
  • PG-104-105-AC Metasys N2 to SNMP converter is an excellent solution for this requirement. This helps the gateway in reading the data from the Energy meters on Metasys N2 and it caches this data internally and then provides it on SNMP when requested from the SCADA system.

Scenario 2

  • There are several UPS units on the site which provide data output on SNMP.
  • The site has a N2 based controller on Metasys N2 that needs data from UPS units on SNMP.
  • A direct exchange of data between UPS units and controller is not possible as the UPS units provide data output on SNMP and controller understands Metasys N2 only.

Solution

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

Outline of Metasys N2 and SNMP

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.

SNMP

Simple Network Management Protocol (SNMP) was originally made for the management of devices such as switches and routers, its usage has grown so much nowadays that it is used for monitoring of nearly any electronic device one can think of.  It is a protocol which is majorly designed to manage networked devices from a single-central location. SNMP is now used to monitor and manage television broadcast studios, airborne military platforms, automated fare collection systems, emergency radio networks, energy distribution systems, and much more.  Microsoft Windows Server 2003 provides SNMP agent software that works with third-party SNMP management software to monitor the status of managed devices and applications.

How to configure the PG-106-104-AA 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-106-104-AA 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-106-104-AA 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-106-104-AA. 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.
