參考IEC 61511或ANSI/ISA-84.00.01-2004第1部分(IEC 61511-1 Mod)了解正式定義。
等同于IEC 61508定義的過程控制系統(tǒng)(PCS)。
actuator A device which cause an electrical
mechanical or pneumatic action to occur when required within a plant component. Examples are valves and pumps. AITA Analogue input termination assembly. alarms and events (AE) An OPC data type that provides time stamped alarm and event notifications. allotted process safety time The portion of the total process safety time allotted to a sub function of that process. application The output binaries produced by the compiler included in the AADvance Workbench software and AADvance-Trusted SIS Workstation software. Once compiled, download the application to the controller. architecture Organizational structure of a computing system which describes the functional relationship between board level, device level and system level components. asynchronous A data communications term describing a serial transmission protocol. A start signal is sent before each byte or character and a stop signal is sent after each byte or character. An example is ASCII over RS-232-C. See also 'RS-232-C, RS422, RS-485'. availability The probability that a system will be able to carry out its designated function when required for use — normally expressed as a percentage.
backplane clip A sprung
plastic device to hold together two adjacent AADvance base units. Part number 9904. Used in pairs. base unit One of two designs which form the supporting parts of an AADvance controller. See 'I/O base unit' and 'processor base unit'. bindings Bindings describe a "relationship" between variables in different AADvance controllers. Once a variable is "bound" to another variable, a unique and strong relationships is created between the two variables and the SIL 3 Certified SNCP protocol is used to verify that the consuming variable is updated with the data from the producing variable. black channel A communication path whose layer (i.e. cabling, connections, media converters, routers/switches and associated firmware/software, etc.) has no requirement to maintain the integrity of safety critical data transferred over it. Measures to detect and compensate for any errors introduced into the black channel must be implemented by the safety critical sender and receiver (by software and/or hardware means) to make sure the data retains its integrity. blanking cover A plastic moulding to hide an unused slot in an AADvance base unit. boolean A type of variable that can accept only the values 'true' and 'false'. BPCS Basic process control system. A system which responds to input signals and generates output signals causing a process and associated equipment to operate in a desired manner, but which does not perform any safety instrumented functions with a claimed safety integrity level of 1 or higher. Refer to IEC 61511 or to ANSI/ISA—84.00.01—2004 Part 1 (IEC 61511-1 Mod) for a formal definition. Equivalent to the Process Control System (PCS) defined by IEC 61508.
