High Performance Protocol Translation

Port 40's AMS::Integration Device provides high-speed, high-efficiency, robust protocol translators for system integrators, as well as electrical and mechanical contractors. The software-only solution is second to none in the industry not only in capability, but in the ease with which configuration can be done and maintained. A single AMS::Integration Device replaces stacks and stacks of expensive hardware-based translators.

The integration device is specifically a BACnet protocol based proxy server and gateway that allows any point within the AMS server system to appear as a BACnet object on a BACnet network. Using this capability, the building manager using a BACnet operator workstation or server has access to critical control information from non-BACnet systems, like MODBUS. BACnet alarms, events, and notifications are all supported.

Millisecond Timestamp Resolution

Get millisecond timestamp resolution for electrical and mechanical system events using Sequence of Events recorders like the SER-3200 from CyberSciences. No other protocol translator on the market has this kind of ability.


CostQuick Replace

The cost of installation and configuration of the AMS::Integration Device is a fraction of the cost of popular hardware-based protocol translators. A single instance of the server can handle tens of thousands of BACnet data points. See specifications below.



Performance of the AMS::Integration Device has been measured and found to be many times that of common hardware based BACnet/IP integration solutions. A major control systems manufacturer has found the performance to be astonishing. Many thousands (not just tens or hundreds) of points can be simultaneously handled. Can it handle the needs of your Data Center? Absolutely, and at a fraction of the cost of hardware based solutions.

Easy to configure

The AMS::Integration Device is fully customizable - present your information to the BACnet workstations exactly how your want it. Configuration is easy and can be scripted using the same AMS web service interface present on all of the AMS line of products. Update properties in bulk, and never again edit another hardware configuration file. The AMS Browser can be used for point and click configuration if you so choose.


Vast hardware and driver support

The Integration Device supports thousands of hardware devices and control systems that lack a BACnet/IP interface. The list of devices supported are the same ones supported by the Automation Management Server - the two products are built on the same core technology.

OPC, BACnet, Modbus, SNMP, and now LonWorks backend devices are all richly supported, and a number of other interfaces are in the works. For other interfaces or drivers, custom development is available at a nominal cost. Support for Modbus based Sequence of Events (SER) Recorders is a regular request. When connected to electrical systems (a breaker panel, for example), the SER's provide millisecond resolution detection of electrical system events, as they occur on the wire. The events are forwarded to the BACnet operator workstation or web system by the AMS::Integration Device.

Have you ever wanted to incorporate live atmospheric and weather data into your BACnet driven web interfaces? Now you can with our new XPath driver for XML and RSS feed document processing. Please remember that accessing such publicly available data on the Internet usually requires outbound connection permission from your network administrator or building systems manager.

Rich MODBUS Mapping

The AMS :: Integration Device has versatile and robust mapping capabilities for MODBUS registers. Virtually any register sequence can be decoded and translated to individual BACnet objects. Port 40 provides a handy Windows tool for constructing not only simple but the most complex maps. Each and every mapping provides a descriptive textual name for BACnet clients. Below is a partial list of register decoding algorithms built into the AMS :: Integration Device:

  • All integer types (8-64 bit), including signed and unsigned
  • 32-bit and 64-bit IEEE floating point types
  • String or Text data
  • Enumerations - 8-64 bit
  • Bit Strings - 8-64 bit
  • Booleans
  • Masked integer (sub-register values)
  • Schneider Electric "Modulo" values - polynomials of 1-4 registers
  • Vendor defined, reusable structured data
  • Coil and Input Status digital maps
This IS what MODBUS should look like.

A single Modbus map is re-usable by every piece of hardware it models.

Numeric types can be scaled or phase shifted according to vendor's specifications. Proper endianess is accomplished by word swapping. Maps can be generated for you by Port 40 support personnel for a nominal fee. Port 40 can also build for you custom processors for your devices requiring some type of internal processing (like Sequence-Of-Event recorders).


BACnet Gateway Device

Maximum number of virtual BACnet networks: 65,535

Maximum number of virtual BACnet devices per virtual network: 65,535

Maximum number of virtual data points per virtual device: 2,147,483,647

The practical total number of virtual data points that the AMS:Integration Device should serve is limited only by capabilities of your BACnet operator workstation.
