Product DescriptionTopThe 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, 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 ProfilingTopInherent 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.
