Page 296 Glossary Accumulator Accumulators represent CPU register and are used as buffer memory for download, transfer, comparison, calculation and conversion operations. Address An address is the identifier of a specific address or address area. Examples: Input I 12.1; Flag Word MW 25; Data Block DB 3. Analog module Analog modules convert process values (e.g.
Page 297: Bus Segment
Glossary A bus is a communication medium connecting several nodes. Data can be transferred via serial or parallel circuits, that is, via electrical conductors or fiber optic. Bus segment A bus segment is a self-contained section of a serial bus system. Bus segments are interconnected by way of repeaters, for example, in PROFIBUS DP.
Page 298: Glossary
Glossary Configuration Assignment of modules to module racks/slots and (e.g. for signal modules) addresses. Counter Counters are part of CPU system memory. The content of "Counter cells" can be modified by STEP 7 instructions (for example, up/down count.) See also System memory Cycle time The cycle time represents the time a CPU requires for one execution of the user program.
Page 299: Device Name
Glossary Default router The default router is the router that is used when data must be forwarded to a partner located within the same subnet. Router In STEP 7, the default router is named . STEP 7 assigns the local IP address to the default router.
Page 300: Diagnostic Interrupt
Glossary Device replacement without medium change IO devices having this function can be replaced simply: ● A removable medium (such as Micro Memory Card) with the stored device name is not required. ● The device name does not have to be assigned using the programming device. The inserted IO device receives the device name from the IO controller, not from the removable medium or from the programming device.
Page 301 Glossary Equipotential bonding Electrical connection (equipotential bonding conductor) which eliminates potential difference between electrical equipment and external conductive bodies by drawing potential to the same or near the same level, in order to prevent disturbing or dangerous voltages between these bodies. Error display One of the possible reactions of the operating system to a runtime error is to output an error message.
Page 302: Functional Ground
Glossary Functional ground Grounding which has the sole purpose of safeguarding the intended function of electrical equipment. With functional grounding you short-circuit interference voltage which would otherwise have an unacceptable impact on equipment. GD circuit A GD circuit comprises a number of CPUs sharing data by means of global data communication, and is used as follows: ●...
Page 303 Glossary Ground The conductive earth whose electrical potential can be set equal to zero at any point. Ground potential can be different from zero in the area of grounding electrodes. The term reference ground is frequently used to describe this situation. HART English: Highway Adressable Remote Transducer Industrial Ethernet...
Page 304 Glossary Interrupt, diagnostic Diagnostic interrupt → Interrupt, process Process interrupt → Interrupt, status A status interrupt can be generated by a DPV1 slave or a PNIO device respectively. At the DPV1 master or the PNIO controller respectively the receipt of the interrupt causes the OB 55 to be called up.
Page 305: Mac Address
Glossary Isochronous Real Time communications → Isochronous Real Time communications Synchronized transmission method for the cyclic exchange of IO data between PROFINET devices. A reserved bandwidth within the send clock is available for the IRT IO data. The reserved bandwidth guarantees that the IRT data can also be transferred even during another high network load (for example TCP/IP communication or additional real time communication) at reserved, synchronized intervals.
Page 306 Glossary Micro Memory Card (MMC) Micro Memory Cards are memory media for CPUs and CPs. Their only difference to the Memory Card is the smaller size. Module parameters Module parameters are values which can be used to configure module behavior. A distinction is made between static and dynamic module parameters.
Page 307 Glossary Parameters 1. Variable of a STEP 7 code block 2. Variable for declaring module response (one or several per module). All modules have a suitable basic factory setting which can be customized in STEP 7. There are static and dynamic parameters. Parameters, dynamic Unlike static parameters, you can change dynamic module parameters during runtime by calling an SFC in the user program, e.g.
Page 308 Glossary Process interrupt A process interrupt is triggered by interrupt-triggering modules as a result of a specific event in the process. The process interrupt is reported to the CPU. The assigned organization block will be processed according to interrupt priority. Process-Related Function PROFINET components →...
Page 309 Glossary PROFINET CBA Within the framework of PROFINET, PROFINET CBA is an automation concept for the implementation of applications with distributed intelligence. PROFINET CBA lets you create distributed automation solutions, based on default components and partial solutions. Component Based Automation allows you to use complete technological modules as standardized components in large systems.
Page 310: Reduction Factor
Glossary Proxy The PROFINET device with proxy functionality is the substitute for a PROFIBUS device on Ethernet. The proxy functionality allows a PROFIBUS device to communicate not only with its master but also with all nodes on PROFINET. You can integrate existing PROFIBUS systems into PROFINET communication, for example with the help of an IE/PB Link or a CPU 31x PN/DP.
Page 311 Glossary Reference potential Voltages of participating circuits are referenced to this potential when they are viewed and/or measured. Restart On CPU start-up (e.g. after is switched from STOP to RUN mode via selector switch or with POWER ON), OB100 (restart) is initially executed, prior to cyclic program execution (OB1). On restart, the input process image is read in and the STEP 7 user program is executed, starting at the first instruction in OB1.
Page 312 Glossary Segment Bus segment → Send cycle Within this interval new data are supplied to an IO device / IO controller in the PROFINET IO system by the IO controller / IO device. The send cycle can be configured separately for each IO device and determines the interval at which data are sent from the IO controller to the IO device (outputs) as well as data from the IO device to the IO controller (inputs).
Page 313 Glossary Subnetwork All the devices interconnected by switches are nodes of the same network or subnet. All the devices in a subnet can communicate directly with each other. All devices in the same subnet have the same subnet mask. A subnet is physically restricted by a router. Substitute Proxy →...
Page 314 Glossary Terminating resistor The terminating resistor is used to avoid reflections on data links. Timer Timers → Timers Timers are part of CPU system memory. The content of timer cells is automatically updated by the operating system, asynchronously to the user program. STEP 7 instructions are used to define the precise function of the timer cell (for example, on-delay) and to initiate their execution (for example, start).
