警报和状态消息作为DP-V1中的另一项功能，DP-V0的设备特定诊断功能得到了增强，并分为警报和状态信息两类。作为DP-V0诊断的主要区别，从设备到主设备的警报通过确认的服务传输。CI854/CI854A不支持DP-V1的警报和状态消息处理。仅支持DP-V0诊断。通过PROFIBUS和CI854/CI854A，您可以获得高的冗余可扩展性。您可以选择配置冗余：•PROFIBUS主单元CI854A•PROFIBUS从单元•PROFIBUS线路。根据您的需要，可以独立配置每种类型的冗余。还支持混合配置。例如，您可以配置由冗余CI854A主单元和冗余PROFIBUS线路组成的冗余PROFIBUS安装，并并联连接冗余和非冗余从单元。
Alarms and Status Messages
As a further function in DP-V1, the device specific diagnosis of the DP-V0 have
been enhanced and divided into the categories alarms and status messages. As the major difference to the DP-V0 diagnosis, the alarms from the slave to the master are
transferred via confirmed services.The CI854/CI854A does not support the alarm and status message handling of
DP-V1. Only DP-V0 diagnosis is supported.With PROFIBUS and CI854/CI854A you have a high scalability for redundancy.
You have the options to configure redundancy for:
• PROFIBUS master unit CI854A
• PROFIBUS slave unit
• PROFIBUS line.
Depending on your needs each type of redundancy can be configured independent
of each other. Also mixed configurations are supported. You can configure for
example a redundant PROFIBUS installation consisting of a redundant CI854A
master unit and redundant PROFIBUS lines and have connected redundant and nonredundant slave units in parallel.
