Connecting Modbus to Metasys

You have two devices in two different buildings on two completely different networks, one that uses the Modbus Plus (MB) protocol to communicate, while the other one talks Metasys N2 protocol and they need to talk to each other. What do you do?

A FieldServer is a protocol converter or gateway that can communicate in many different protocols and physical layers including Modbus Plus (MB) protocol and the Metasys N2 protocol. The Fieldserver acts as a middle man between the two devices. It reads data from one device, stores it internally and makes it available to the 2nd device using another protocol. This is how the FieldServer converts Modbus Plus (MB) data to Metasys N2 data.

It's a simple solution to a common problem that we can help you with.

Modbus Plus (MB)

This solution is provided to protect your investment in legacy / obsolete equipment. The solution uses a MB+ card installed in a FieldServer. This makes the solution more expensive than most FieldServer solutions.


Modbus Plus protocol is a time-proven, robust communications platform with a huge installed base and industry acceptance. It is a high-speed (one megabaud) network that supports both peer-to-peer and master/slave type communications. Modbus Plus is used by Modicon PLCs, operator interfaces, PCs and other data sources to communicate throughout an automated facility over a twisted-pair cable. Modbus Plus provides all of the benefits of an effective communications network including reduced wiring and maintenance costs, improved productivity through diagnostics, accuracy and information flexibility.

Metasys N2

Metasys N2 is part of Johnson Controls family of protocols. Metasys N2 is a diverse protocol used by many different devices all with there own quirks and definition of the standard, it can be complicated to get Metasys N2 to talk to other devices. Fieldserver takes care of the complicated issues with Metasys N2 by becoming a middle man that sits between your Metasys N2 device and your other devices. The FieldServer can talk Metasys N2 on one side and anything else you want on the other.

 

Large number of N2 devices ?

Transitioning an existing N2 installation to BACnet ?

For conversions with a large number of N2 devices or for solutions where you need to keep The Metasys by JCI head ends/controllers in place please visit these pages for an appropriate solution. The S4 solution connects to the trunk(s), discovers all the devices and auto maps them to BACnet IP. The original controller can be kept in place and will continue to communicate through the gateway with its N2 devices. You can remove it later or never - your choice.
