下图显示了连接到冗余AC 800M控制器的冗余PROFIBUS。PROFIBUS基本基本功能DP-V0循环数据通信DPM1（DP主设备1级）与其分配的从设备之间的数据通信由DPM1按照定义的重复序列自动处理。对于每次用户数据传输，主设备可以向从设备写入多达244字节的输出数据，并从从设备读取多达244字节输入数据。数据在一个过程中同步读取和写入。在这种情况下，通过Control Builder M中的HW配置完成从设备到DPM1（CI854/CI854A）的分配。DPM1和从设备之间的数据通信分为三个阶段：参数化、配置和数据传输。在主设备在数据传输阶段包括DP从设备之前，在参数化和配置阶段进行检查，以确保配置的设置点配置与实际设备配置匹配

Cyclic Data Communication
The data communication between the DPM1 (DP Master Class 1) and its assigned
slaves is automatically handled by the DPM1 in a defined, recurring sequence. With
each user data transfer, the master can write up to 244 bytes of output data to the
slave and read up to 244 bytes of input data from the slave. The Data is read and
written synchronously in one procedure.The assignment of the slaves to the DPM1, CI854/CI854A in this case, is done via
the HW configuration in Control Builder M.The data communication between the DPM1 and the slaves is divided into three
phases: parameterization, configuration and data transfer. Before the master
includes a DP slave in the data transfer phase, a check is run during the
parameterization and configuration phase to ensure that the configured setpoint
configuration matches the actual device configuration
