Veeder-Root to Metasys N2

Quickserver Gateway (Serial-Ethernet)

QuickServer is a high performance, fully configurable, cost effective Building and Industrial Automation gateway for integrators to easily interface devices to networks in commercial buildings and industrial plants.

System integrators world-wide have benefitted from the value of the powerful line of interoperability gateways offered by FieldServer. Now, QuickServer adds to that value by running the same robust FieldServer protocol conversion software on a highly cost effective platform backed by the experience, engineering expertise and proven technical support that integrators have come to expect from FieldServer.

QuickServer is available in two series. The FS-QS-10XX Series is preloaded with two BAS drivers (serial, Ethernet and/or LonWorks) from a choice of Modbus RTU, Modbus TCP, BACnet/IP®, BACnet MS/TP, LonWorks®, JCI Metasys® N2 and SNMP. Each QuickServer can handle up to 250 points.

The FS-QS-12XX Series QuickServer is available to use any Serial, Ethernet or LonWorks driver in the extensive FieldServer driver library. The FS-QS-12XX Series can handle up to 500 points and is available with a choice of RS-485, RS-232 or RS- 422 serial ports, KNX or M-Bus, in addition to Ethernet and LonWorks (optional).

Each QuickServer includes browser-based tools to make it easy to set-up QuickServer and perform diagnostics including determination of status, network settings, node information, map descriptors and more. The USB flash drive also includes the Discovery utility to determine what FieldServers are on a network.

Metasys N2

The Metasys® N21 by Johnson Controls network supports communications with a diverse range of devices. Many N2 compatible devices use their own version of the protocol and care must be taken to ensure that the device of interest is covered by the FieldServer implementation.

At present the FieldServer Metasys® N2 driver will support communications with the following devices or classes of devices when acting as a Client:

  • N2Open-compliant devices. N2Open is a published N2-compatible protocol enabling 3rd party device vendors to integrate with N2.
  • VMA 1400 series (with restrictions)
  • DX9100 and XT9100

When acting as a Server the FieldServer Metasys® N2 driver can emulate an N2Open device only.


The Veeder-Root Serial Driver allows the FieldServer to transfer data to and from devices over either RS- 232 or RS-485 ports using Veeder-Root protocol as defined in Veeder- Root Document 576013-635 Revision J. The Veeder-Root Driver supports TLS350 as per Veeder-Root Document 576013-635 Revision Y, and TLS450 as per Veeder-Root Document 577013-950 Revision G. Since the data protocol is the same for the TLS-350+ as for TL-S350, it is assumed that the driver will support the TLS350+ but this has not been tested. The Driver also successfully communicates with the TLS-450 as it has the same data protocol. Please refer to the driver manual for hardware connections.

The FieldServer emulates a Client.

The Veeder-Root Serial Driver is a poll response driver. Only one query or command can be processed at a time.

A limited set of the queries and commands defined in the protocol specification have been implemented. The reason for the limitation is two-fold. Firstly, not all commands/queries will have any meaning to a Server device as they are principally defined to configure the Veeder-Root Device. Secondly, some commands return very complex data sets which cannot be processed in a method suitable for loading into the FieldServer’s Data Arrays.

The driver is capable of exposing its communications statistics which allows them to be monitored using a Server device.
