19. 3 7 PROFIBUS DP 3 2 Short Description of PROFIBUS DPV1 3 2 1 General PROFIBUS DPV1 is an enhancement of PROFIBUS DP which provides the possibility of acyclic data communication Acyclic and centrally directed data transfer between master and slaves is characteristic for the standard functions of PROFIBUS DP A Class1 master PLC controls the cyclic exchange of process data with the slaves The data exchange is carried out in rotation and in a defined order The data which have to be transmitted are projected beforehand Via acyclic communication functions PROFIBUS DPV1 now offers the possibility to transmit data to the slave in addition to the cyclic process data 3 2 2 Acyclic data transfer The need for acyclic data transfer exists wherever slave devices which provide several parameterization options have to be parameterized during operation Typical examples are the parameters of a drive like limit values rotational speed or torque operation mode and the generation of an error list Acyclic services are handled with low priority parallelly and additionally to the cyclic process data transfer The negative influence on the speed of the high priority process data transfer shall thus be minimized 3 2 3 DPV1 functions The DPV1 functions consist basically of the services Read and Write The master uses these services for read or write access to data blocks in PROFIBUS In addition to that an intiate and abort servi

The system response to an error in the data transfer phase of the DPM1 e g a failure of a DP slave is determined by the operating parameter Auto Clear If this parameter is set to True then the DPM1 switches all outputs of the assigned DP slaves to the safe status as soon as a DP slave is no longer capable of user data transfer Then the DPM1 changes to the Clear state If this parameter is set to False then the DPM1 will retain its operating condition also in the event of an error and the user can determine the system response Data transfer between DPM1 and the DP slaves Data exchange between the DPM1 and the assigned DP slaves is automatically controlled by the DPM1 in a determined fixed order During configuration of the bus system the user assigns the DP slaves to the DPM1 It is also defined which DP slaves are to be included in or excluded from cyclic user data transfer Data exchange between DPM1 and the DP slaves can be divided into the phases parameterization configuration and data transfer Prior to including a DP slave in the data transfer phase the DPM1 checks during the parameterization and configuration phase whether the programmed required configuration complies with the actual device configuration This check is used to verify that the device type the format and length information as well as the number of inputs and outputs accord The user thus is securely protected against parameterization errors Additionally to
