DPV2: slave-to-slave communication takes place in addition to cyclic and acyclic data transfer:--> is not supported by the recorder. The VPC3+C handles the message and address identification, the data security sequences and the protocol processing for PROFIBUS-DP. However, in the case of Profibus, the Profibus specification does not simply refer to the existing RS-485 specification. The optional use of DPV1 Diagnosis telegrams with Status Information was invented April 2008.
Optionally, the SG-gateway is also available with a 3G or even a 4G/LTE modem as an additional communication channel. Siemens Simatic Step 7 Basic, V13 programming software was used for this application example. In 1997, the profile was extended by the positioning function and the faster PROFIBUS-DP protocol was added.
The selection is made by using one of the associated GSD files.
This is an extended protocol that allows for acyclic communication for parameter configuration . When this option is installed it is possible to read the process data from the Flow meter. PROFIBUS is a powerful and versatile 2- wire non-proprietary open field bus standard defined by several international standards such as EN 50170, IEC 61158 together with different device profiles.
On the one hand, it can be used for simple, intelligent applications that make do with the integrated C31 core. PROFIBUS-PA is based on PROFIBUS-DP and, using a linking device called a segment coupler, permits transparent communication between general purpose automation and process automation networks, making PROFIBUS ideal for hybrid applications where factory and process devices intermingle.
The new version has a number of practical and important extensions and simplifications. Thanks to its broad range of connectable field devices, PROFIBUS DP has (in distributed I/O) acquired the status of an internationally acknowledged standard fieldbus system. The Edition, based on PROFIBUS-FMS, was published in 1991 and included the definitions for the closed-loop speed control function. The manual is targeted at a technical audience in the industrial communications field with a sound working knowledge of PROFIBUS DP-V1. This protocol has three versions within the application layer – DP-V0, DP-V1 and DP-V2. 8 The topology: networks and control technology Typical control platforms siemens (Profibus and ProfiNeT) Products, systems and services for drive, control and information technology, from components all the way to holistically integrated systems.

The new functions and applications of PROFIBUS DP in SIMATIC S7 on the basis of STEP 7 Version 5.1 SP3 are described, along with setting of an equidistant DP bus cycle and the new signals Status Alarm , Update Alarm and Manufacturer-Specific Alarm . Some automation components from SIEMENS and other companies already have the DPV1 functionality. 1.5 Approvals and Certifications More approvals and certifications are available. PROFIBUS DP (Decentralized Peripherals) is used to operate sensors, actuators and input/ output deported via a centralized controller. In this application, it functions as a gateway and operates as the ProfibusDP Slave. Cyclical communication means that data transfer takes place all the time with a certain update rate. ProfiBus DP most often uses a single class 1 master device (mono-master), cyclically polling many distributed slaves. For safety information on and technical data of the gauges, please refer to the respective operating manuals ( , ).
In addition the acyclic communication and alarm messages, described in DPV1 extension, are supported. Only class 1 masters have write (setting the outputs) and read (reading inputs) access to the slaves allocated to them. European Standard EN50170  which was updated in 1998 with an extension, named DPV1 , whose major feature was the introduction of acyclic communication services. the Profibus standard: Profibus DP (Decentralised Periphery) is the high speed solution designed and optimised especially for communication between automation systems and decentralised field devices. All adjustments and settings can be made from the control panel without opening the cover.
