GE PRG-MODEM输入输出模块
要将PROFIBUS Power Hub用作从属设备，将使用设备管理提供的现有对象类型。有关设备类型对象的更多信息，请参阅第62页的设备管理PROFIBUS和HART。将PROFIBUS Power Hub配置为从属设备时，应配置PA_Bus_Cfg_Diag模块的以下设置：如果PROFIBUS Power Hub在PROFIBUS DP上配置为冗余，则PROFIBUS Power Hub必须与CI854建立通信，在与PROFIBUS PA上连接的设备通信之前。PROFIBUS从地址PA设备的配置默认配置位置126。位置126不能用于正常的循环通信。位置126仅用于识别PROFIBUS上的新从属设备。
To use the PROFIBUS Power Hub as a slave device, an existing object type
provided by Device Management is used. For more information about Device Type
Objects see Device Management PROFIBUS & HART on page 62.
When configuring the PROFIBUS Power Hub as a slave device, the following
settings for PA_Bus_Cfg_Diag module should be configured:If the PROFIBUS Power Hub is configured as redundant on PROFIBUS DP, then
the PROFIBUS Power Hub has to establish communication with the CI854,
before communicating with the connected devices on PROFIBUS PA.Configuration of PROFIBUS Slave Address
PA devices have as default the position 126 configured. The position 126 can’t be
used for the normal cyclic communication. The position 126 is only used to identify
new slaves on the PROFIBUS.
