11. In straight PROFIBUS FMS mode an FMS master can control the MOVITRAC 31 inverter via the process data channel using the communication objects listed in the table The process output data are transferred during this process to the appropriate process output data object by the Write serv ice Process input data are read by the Read service into the relevant process input data object Whereas the process input data objects can generally only be read the process output data objects have both read and write access So in mixed mode DP FMS for example the process output data sent by the DP master can be read and visualized by the FMS master The data consistency required for the exchange of data via PROFIBUS FMS is achieved by provid ing the appropriate communications objects for each process data length With a process data length of 3 for example process data can be exchanged using the objects 3 PI and 3 PO Fig 45 shows the various ways of accessing communications objects in mixed mode DP FMS PROFIBUS DP master PROFIBUS FMS master 9 Visualization S56 Read access Read Wri access o PO1 Pli ys amp PO2 PI 2 Lia amp P03 PI3 VE lt 01195AEN Fig 4
