Siemens Applied Automation Key Bus Physical / Functional Requirements Process Gas Chromatography Sampling System Analyzer House (typical) Note: ** Often, sampling systems are mounted separately from related analyzer. ** Some systems mounted attached to analyzer. 1. Analyzer may be up to 10 m from sampling system. Total cable length <=20 m 2. Number of bus “instances” to be limited to simplify analyzer control and reduce cost; <= 2 instances preferred, excluding power sources 3. Bus to support very large number of participating component and analyzer suppliers (unlimited ~ >1000’s) 4. Bus to provide for sensing and control of: valves, pressure, flow, temperature 5. Component power to be supplied via bus (rather than separate power bus) to simplify I. S. and. Update physical issues Siemens ro Ne.

Components to be mounted in Division 1 / Zone 1 hazardous area. Bus to be intrinsically safe and to support components mounted in hazardous area Design goal for flammability ignition temperature to be T 4 (135°C) with minimum at least T 3 (200°C). Component ambient temperature to be >=70°C Sampling system to be capable of supporting at least 30 separate streams Bus to support at least 200 component / functional instances Bus to support component types in any combination up to the total number of components in the system. Bus to support at least 4 simultaneously active valves Bus to supply necessary component power management functions Bus to support replacement of components while live without interruption of bus operation Bus to provide for control of high-power components that do not draw power from the bus itself (eg. heaters) Note: Requirements listed in no particular order. Siemens Update ro Ne. SSI / CPAC. ppt Interior of cabinet is considered hazardous due to leakage of flammable gases in a closed area. Mounting area may be hazardous or not.

Siemens Applied Automation Key Bus Requirements Functions Defined by Bus Process Gas Chromatography Method of human interface for SAM. External communications Bus must provide a method for analyzers to get “on” the bus. Bus must provide a method for components connect “to” the bus… Analyzer SAM “SAM” may be either a physical device or a software implementation in the analyzer. P V T A Siemens Update ro Ne.
