Modbus Introduction
The Advantage Controls MegaTron is capable of supporting TCP/IP communications via Ethernet and Data Modem. This allows for connections to our custom embedded web server via local networks and our browser based WebAdvantage service. Advantage Controls has now implemented Modbus/TCP support which allows interfacing with more customizable PC applications using HMI/SCADA and stand-alone HMI systems.
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 firewalls 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.
Modbus Overview
Modbus is a messaging protocol developed by Modicon in 1979. It’s used to establish a client-server communication between Modbus intelligent enabled devices. Modbus is a de facto standard open and widely used network protocol within industrial manufacturing environments. The protocol is used totransfer analog I/O and register data between Modbus enabled systems.
The Advantage Controls MegaTron utilizes Modbus/TCP protocol via an Ethernet handoff. Modbus is an application layer messaging protocol, located at level 7 of the OSI model providing client-server communications between devices positioned different types of buses or networks.
Addresses use one based numbering. For systems that use zero based numbering remove 1 (3001 becomes 3000 2002:12 becomes 2001:11) All address are read-only holding registers. Data is sent in little-endian byte order. If data does not appear correct in your system you can try byte swapping or word swapping. Communication card can talk to WebAdvantage and BMS/EMS systems at the same time. For registers size 2 values you must look at both values to get correct reading.
Note: To write to the Registers use Function Code 16.

MegaTron Quick Steps
Connecting to MODBUS enabled MegaTron
This guide is designed to help with connecting a MODBUS enabled MegaTron to a local BMS.
Note: Screens may vary slightly between models.
MODBUS Setup
- Step 1:
Press Setup/Run, CONFIGURE, NETWORK, SETTINGS. (See figures 1, 2, 3 and 4. H15 dual cards add figure 3B. H15 only available for MegaTron MT.) - Step 2:
Press DHCP. (See figure 5.) 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:
Use the up/down arrows to enable DHCP. Press Enter to accept. (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.
