Glossary DP slave DP standard E Error handling via OB Error indication ET 200 F Field Field device Glossary-4 A slave which is operated on the PROFIBUS with the PROFIBUS-DP protocol and which complies with EN 50170, Volume 2, PROFIBUS, is referred to as a DP slave. The bus protocol of the ET 200 distributed I/O system; it complies with EN 50170, Volume 2, PROFIBUS. When the operating system detects an error (for example, STEP 7 access error), it calls the specific organization block (error OB) for this error, where the further response of the CPU can be specified. One of the possible responses of the operating system to a delay error. The other possible responses are: error response in the user program, STOP status of the IM 153. The ET 200 distributed I/O system with the PROFIBUS-DP protocol is a bus designed for connecting distributed I/O units to a CPU or a suitable DP master. ET 200 is distinguished by its fast response times, since only small volumes of data (bytes) are transferred. ET 200 is based on EN 50170, Volume 2, PROFIBUS. ET 200 operates according to the master-slave principle. The DP master may be an IM 308-C master interface, for example, or a CPU 315-2 DP. The DP slaves may be distributed I/O units (ET 200B, ET 200C, ET 200M, ET 200U) or DP slaves from Siemens or other vendors. Either, an area of a plant outside the control room where measured values can be acquired through communication or manipulated values can be sent to actuators. Or part of a message, for example an address field or command field, which has been allocated a particular function. The size or other rules for the interpretation of each field are part of the protocol specification. A transducer which is located in the field and exchanges data with the CPU via communication.

Quality assurance system in the USA. The FSK procedure is a data modulation technique which is suitable for data transport via normal cables. Two audio frequencies are used to encode the binary values “0” and “1” in the frequency range 300 - 3000 Hz. In the HART protocol the FSK signal is transmitted via a current loop. Frequency shift keying The conductive earth whose potential can be assumed to be zero at any point. In the vicinity of grounding electrodes, the ground may have a potential other than zero. The term “reference ground” is frequently used in this connection. One or more conductive part(s) which make good contact with the ground. Highway Addressable Remote Transducer. HART is a registered trademark of the HART Communication Foundation. Glossary Analog modules ( analog input or analog output) which can carry out HART communication in addition to their analog value. HART analog modules can be used as a HART interface for the HART field devices. The HART field device works as a slave and is controlled by the master by means of HART commands. The master sets the HART parameters or requests data in the form of HART responses. Transfer of data between a master (for example, HART analog module) and a slave ( HART field device) via the HART protocol. The HART Communication Foundation (HCF) was founded in 1993 to disseminate information on the HART protocol and to develop the protocol further. The HCF is a non-profit-making organization which is financed by its members. Glossary-5
