QuickServer – LonWorks to Modbus RTU

FS-QS-1011-0085 QuickServer – LonWorks to Modbus RTU

The FS-QS-1011-0085 QuickServer provides a cost-effective, easy to use interface from LonWorks to Modbus RTU. The QuickServer is delivered with both drivers preloaded and ready to be configured using the provided instructions and software.


QuickServer Key Features:

  • Ability to interface up to 250 points of common BAS protocols
  • Multi-configuration capability; specific configurations selectable via DIP switches or software
  • Flat panel mount standard, DIN rail mount option
  • DIP switches to select baud rate or node ID on the fly


LonWorks driver:

  • The FieldServer LonWorks device can be used with explicit and/or implicit addressing and can be bound to a maximum of 15 other LonWorks nodes. The QuickServer can handle a maximum of 250 explicitly addressed nodes. The QuickServer currently supports a default of 63 network variable aliases to avoid network variable connection constraints.
  • QuickServer can transfer data (Network Variables) in two ways
    • It can poll (request data from) other devices at a regular interval
    • It can send Network Variable Updates at a regular interval, when data has changed, or, in throttled mode using maximum and minimum send time and change on delta parameters
  • QuickServer can be configured by Network Management Tools such as LonMaker. For binding (implicit mode), a Network Management Tool is necessary to create the bindings.
  • The External Interface File (.XIF) for the QuickServer can be uploaded from FieldServer for a particular application
  • Driver type: Client or Server
  • Connection type: FTT-10 Free Topology Network Transceiver
  • Data types supported:
    • Integers (Long, short, signed, unsigned)

    • Bit


Modbus RTU driver:

  • Driver type: Client or Server
  • Connection type: RS-232 or RS-485 (Two-wire, Half-Duplex)
  • Baud rate: 110 – 115200, standard baud rates only
