hand-held equipment
Equipment which is intended to be held in one hand while being operated with the other hand. HART HART (Highway Addressable Remote Transducer) is an open protocol for process control instrumentation. It combines digital signals with analogue signals to provide field device control and status information. The HART protocol also provides diagnostic data. (For more details of HART devices refer to the HART Application Guide, created by the HART Communication Foundation, and their detailed HART specifications. You can download documents from www.hartcomm.org.) high demand mode Where the Safety Instrumented Function in the Safety System only performs its designed function on a demand, and the frequency of demands is greater than one per year. hot swap See live insertion. I I/O base unit A backplane assembly which holds up to three I/O modules and their associated termination assembly or assemblies in an AADvance controller. Part number 9300. See 'I/O module' and 'termination assembly'.key connector The receptacle on the AADvance controller for the program enable key. A 9-way 'D' type socket, located on the 9100 processor base unit.
I/O module
A collation of interfaces for field sensors (inputs) or final elements (outputs), arranged in a self-contained and standardized physical form factor. IEC 61000 A series of international standards giving test and measurement techniques for electromagnetic compatibility. IEC 61131 An international standard defining programming languages, electrical parameters and environmental conditions for programmable logic controllers. Part 3, which is entitled 'Programming Languages', defines several limited variability languages. IEC 61508 An international standard for functional safety, encompassing electrical, electronic and programmable electronic systems; hardware and software aspects. IEC 61511 An international standard for functional safety and safety instrumented systems (SIS) for the process industry, encompassing electrical, electronic and programmable electronic systems, hardware and software aspects. indicator A device which can change its state to give information. input (variable) A value passed from an I/O module to the processor module. instruction list An IEC 61131 language, similar to the simple textual language of PLCs. See 'limited variability language'. integer A variable type defined by the IEC 61131 standard. IXL IXL stands for ISaGRAF eXchange Layer. This is the communication protocol between ISaGRAF based components.
ladder diagram
An IEC 61131 language composed of contact symbols representing logical equations and simple actions. The main function is to control outputs based on input conditions. See 'limited variability language'. LAN Local area network. A computer network covering a small physical area, characterised by a limited geographic range and lack of a need for leased telecommunication lines. live insertion The removal and then reinsertion of an electronic module into a system while the system remains powered. The assumption is that removal of the module and reinsertion will cause no electrical harm to the system. Also referred to as 'hot swap'.
