SlotServer ControlLogix — LonWorks Open Interface Module

Part #: FS-RA-CLX-LON-001
Module Version: 0.00

Product Description

The SlotServer LonWorks Open Interface allows an Allen Bradley ControlLogix platform to pass data between a ControlLogix CPU and a standard LonWorks communications network. The SlotServer Module provides a standard generic profile in LonWorks that allows most of the more common Standard Network Variable Types (SNVT’s) to be bound to the SlotServer for data transfer.

Physically configured to plug into a standard ControlLogix rack, the SlotServer Module is configured using standard RSLogix message block reads to allow for efficient transfer of large blocks of data.

SlotServer provides serial and Ethernet ports to enable ControlLogix interface to any of the 80+ protocols available in the FieldServer driver library including BACnet, Metasys by JCI, Modbus, DNP 3.0 and a wide range of proprietary and legacy protocols used in the building automation, fire alarm panels and process control industries.

About LonWorks and Profiling

Inherent to the design of LonWorks is the intention that all nodes residing on a LonWorks possess a profile which accurately describes the network variables (tags) available to the LonWorks network. This profile is declared to the LonWorks network by means of an External Interface File (XIF). This XIF remains unchanged for any particular profile. In other words, a change in the XIF is by definition a new profile.

The Open Interface profile for SlotServer provides a generic list of SNVT’s that can be used to bind the most common LonWorks data types to the SlotServer for data transfer. This document describes the fixed Open Interface profile for the SlotServer. However, as a LonMark compatible product, the SlotServer platform is also capable of supporting other profiles. For further information, please contact FieldServer Technologies and enquire about available Specific Profiles and other SlotServer Profiling Services

Technical Specifications

Slot width 1
BackPlane Current Load 0.6 A
Operating Temperature 0o to 60 o C (32 o to 140o F)
Storage Temperature -40o to 85o C (-40o to 185o F)
Humidity 5 – 95% (non-condensing)
Allen Bradley Platform: ControlLogix 1756 Rack
LonWorks Connection type: TP/FT-10
LonWorks Connection Capability: As an implicitly bound object in LonWorks, the LonWorks protocol supports the binding of this device to no more than 15 other nodes. Note: A LonWorks Network Management Tool (e.g.: LonMaker, Rover, LonWatcher etc) is required to commission a LonWorks network. This tool is used for creating the variable bindings on the network.
