A current and therefore voltage that varies over time. Typical power supplies oscillate as sine waves at either 6. Hz or 5. 0Hz. Technically, at 6. Hz the current is reversing direction 6. See also AC, Direct Current. Analogsearch for term. A value such as voltage or current which can be at any level between certain limits. With PLCs this typically refers to signals that range between 0 and 1. A. See also ADC, Digital. Synonyms Analogue. Analog to Digital Convertersearch for term. Analog to digital converter. A circuit or device that inputs an analog signal and converts it to a digital value. The resolution refers to number of bits used to indicate the analog value. See also AD, ADCASCIIsearch for term.

See Binary People Learning your 1s and 0s. See also Bit. Binary Coded Decimalsearch for term. A PLC coding system in which a word of 1. Thus a word will go from 0 to 9. This technique is also used for devices like thumbwheel switches. See also BCD, Bit, Word. Bitsearch for term. One binary digit. A bit can be either a 1 or 0, either on or off. This is the smallest piece of information in the PLC. Typically eight bits make a byte and 1. See also Binary, Binary Coded Decimal, Byte, Word. Blocksearch for term. A group of bytes or words. A term often used when transmitting or moving areas of memory. See also Byte, Word. Block Diagramsearch for term. An electrical schematic that represents the exact layout of the components, connections and wiring. See also Ladder diagram, Logic diagram. Booleansearch for term. A system based on logical states such as AND, OR, NAND, NOR, NOT and XOR. The symbols can be used singly or in combination to form circuits that perform true or false operations. Branchsearch for term. A parallel logic path on a ladder logic rung. Broadcastsearch for term. A networking term indicating that the message should be sent to all slavesclients. Buffer Memorysearch for term. A register or group of registers used for temporary storage of data. Most often used in communication to compensate for different transmission rates and reception of data. Bugsearch for term. Problems in software or hardware design that cause undesired behavior. See The first actual software bug. Burnsearch for term. The process of writing information to PROM memory. The device that does the writing is called a burner. Burn insearch for term. A testing procedure used to run a device at high temperatures to increase the probability that any component weakness will be revealed. This ensures that the design is durabile and meets specifications. Bussearch for term. In PLCs it is a set of parallel conductors used to deliver information at a high rate between electronic components. The term is also used for power distribution connectors. See also Back Plane. Bytesearch for term. A group of bits forming a piece of data. Usually a subset of a word consisting of eight bits. See also Bit, Block, Character, Wordc. CEsearch for term. An approval given to a product that conforms to the standards of the European Common Union. Channelsearch for term. An input or output on a PLC card that requires more then one connection point. An example is a isolated current signal channel that requires a positive and negative wire into the PLC card. See also Points. Charactersearch for term. A single byte that holds a letter or punctuation. See also ASCII, Byte. Chassissearch for term. See also Rack. Checksumsearch for term. Used in communications to ensure that the transmission has no errors. It is the numerical sum of all transmitted bytes and is placed at the end of the transmission. Chipsearch for term.
