Advantage Controls Mega Tron Controller Instructions

Advantage Controls Mega Tron Controller

Overview

The MegaTron controller supports BACnet communications with Building Management Systems and WebAdvantage. BACnet uses an object-oriented model so systems can interoperate over shared networks to exchange control/status functions.

Object/property support matrix: “See table 1-1 Object/Property Support Matrix.” (The table content is shown as property support markers but is not enumerated as concrete max values in the source excerpt.)

Example object instance summaries (examples shown in source excerpt): Binary Input objects BI-000 to BI-003; Binary Value objects BV-012 to BV-273 (multiple alarm/monitor functions); Analog Input objects AI-000 to at least AI-071 shown; Analog Value objects AV-000 to at least AV-126 shown; Multi-State Value objects MSV-000 to MSV-019 shown.

Quick Setup Steps

1. Open setup menus: Press Setup/Run, then CONFIGURE, NETWORK, SETTINGS.
2. Select BACnet: Press BAC. If options are not visible, enable the dual network card (source note).
3. Enter instance/port: Enter the DEVICE INSTANCE and PORT. Press Enter to accept on each.
4. Reset communications card: Press RESET, then press Enter to accept; wait for the communications card reset countdown.
5. Reboot controller: After reset, cycle power to the controller.
6. Set device identifier (MegaTron XS): Go to Configure menu → Network settings → BAC and enter the device object identifier. The device object instance number range is 0 to 4194303, and 4194303 is described as “unconfigured” and not a valid device instance number.

BACnet Introduction

• The MegaTron controller is capable of connecting to the WebAdvantage Server and most Building Management Systems. The WebAdvantage service requires a gateway to the internet with firewall and security rules in place. The
• Building Management System needs to be on the same subnet  to properly receive traffic from the MegaTron. This may require some advanced routing of network traffic within the network wiring or programming of advanced switching equipment. The datatraffic for both is provided via the same Ethernet cable coming from the MegaTron.
• The BACnet protocol allows interfacing with more customizable PC applications using HMI/SCADA and stand-alone HMI systems

BACnet Overview

• BACnet is an American National Standard. The BACnet protocol allows the creation of an automation and controls system which may interoperate with other BACnet systems. In BACnet terms, interoperate means that two or more
• BACnet-speaking computer systems may share the same communications networks, and ask each other to perform various functions on a peer-to-peer basis.
• BACnet’s flexibility has two important benefits: vendor-independence and forward-compatibility with future generations of systems. This is accomplished using an object-oriented approach for representing all information within each controller. Since BACnet is based on standards, it provides maximum benefits for both the vendor who designs BACnet systems, and the specifier or owner of those systems.

Protocol Implementation

• Applications Software Version: JA.16.0 and higher
• Firmware Revision: JA.16.0 and higher
• BACnet Protocol Revision: 24
• BACnet Standardized Device Profile (Annex L): BACnet Application Specific Controller (B-ASC) BACnet Interoperability Building Blocks Supported (Annex K):
  • DS-RP-B
  • DM-DDB-B
  • DM-DCC-B
  • DM-RD-B
• Standard Object Types Supported: See table 1-1 “Object/Property Support Matrix”. Data Link Layer Options: BACnet IP, (Annex J)
• Character Set Supported: ANSI X3.4

Connecting

• This guide is designed to help with connecting a BACnet enabled MegaTron to a local BMS.
• Note: Screens may vary slightly between models.

BACnet Setup

• Step 1: Press Setup/Run, CONFIGURE, NETWORK, SETTINGS. (See figures 1, 2, 3 and 4. H26 dual cards add figure 3B. H26 only available for MegaTron MT.)
• Step 2: Press BAC. (See figure 4.) Note: If these options are not visible, the dual network card needs to be enabled. See enabling dual network card to continue setup.
• Step 3: Enter the DEVICE INSTANCE and PORT. Press Enter to accept on each. (See figure 6.)
• Step 4: Press RESET and then press Enter to accept. The communications card will reset after a short countdown. (See figures 7 and 8.)
• Step 5: After the communications card has been reset cycle power to the controller.

MegaTron XS Setup

• The MegaTron XS will be a “device object” on the particular BACnet network. Each device object (your MegaTron XS) must have an object identifier that is unique network wide. The device object instance number is normally configured on site after the device is installed. The device object instance number range is between 0 and 4194303. Note that 4194303 is known as “unconfigured” and is not really a valid device instance number. All devices are required to respond with their own Device object instance number when 4194303 is requested.
• To enter your device object identifier, go to the Configure menu in the MegaTron XS and select the Network settings. Then select BAC.

Troubleshooting

• Setup menu options not visible: The manual notes that if the BAC options are not visible, the “dual network card needs to be enabled.”
• After BACnet reset: The manual instructs that after pressing RESET and accepting with Enter, the communications card will reset after a short countdown, and then you must cycle power to the controller.
• Network not receiving traffic from MegaTron: The manual states that the Building Management System needs to be on the same subnet to properly receive traffic from the MegaTron, which may require advanced routing or advanced switching equipment programming.
• WebAdvantage connectivity requirements: For WebAdvantage, the manual states that an internet gateway with firewall and security rules in place is required (if you are using WebAdvantage service).
