Glossary HART field device HART hand-held device HART interface HART parameter assignment tool HART parameters HART protocol HART responses HART signal HART status byte Glossary-6 Smart field device which has special functions in accordance with the HART norm. This enables the field device to understand HART communication. The HART hand-held device is the original parameter assignment tool produced by Fisher-Rosemount Ltd. for HART field devices. It is connected directly to the ports of the field devices. The HART hand-held device is used to set the HART parameters. Part of system via which a HART field device can be connected. The HART interface represents the master for the field device. As far as the system is concerned, however, the HART interface is a slave which can be fed by various masters on the system. The HART parameter assignment tool is one example of a master. The PLC itself is another master. The HART parameter assignment tool enables you to set the HART parameters. It can be a HART hand-held device or a parameter assignment tool which is integrated into the system, for example, SIMATIC SIPROM. The HART parameters describe the configurable properties of HART field devices which can be modified via the HART protocol. The settings can be made with a HART parameter assignment tool. The HART protocol is the industrial standard for extended communication with smart field devices. It contains the HART commands and HART responses. The HART field device transfers data at the request of the master. These data are measurement results or manipulated values, or the values of HART parameters. A HART response always contains status information in the form of HART status bytes. Analog signal on a current loop of 4 - 20 mA, where the sine waves for the HART protocol are superimposed with the aid of the FSK procedure - 1200 Hz for the binary “1” and 2200 Hz for the binäry “0.” The status information which consists of the 1st and 2nd status byte of the HART response and which the HART field device uses to provide information on the HART communication, the receipt of the HART command, and the device status.

The HART transfer area consists of data records. Each client is allocated its own area of data records, via which the server and it can exchange data. HART Communication Foundation The operating system of the CPU has 10 different priority classes which control execution of the user program. These priority classes include interrupts, for example, hardware interrupts. When an interrupt occurs, the operating system automatically calls a corresponding organization block where the user can program the reaction desired. Part of the S7-300 backplane bus in the automation system; it is optimally designed for fast signal exchanges between the IM 153 and the signal modules. Both user data (e.g. the digital input signals of a signal module) and system data (e.g. the default parameter records of a signal module) are transferred on the I/O bus. In isolated input/output modules, the reference potentials of the control circuit and the load circuit are galvanically isolated from one another, for example by means of optocouplers, relay contacts, or transformers. The input/output circuits can be connected to a common potential. Product Certification Center. Power supply for the signal and function modules and the process I/O connected to them.
