Profibus DP Redundant Networks with Redcom

The MPA uses CAM20 to convert between Modbus RTU and Profibus DP. This section describes the data mapping
between the Profibus DP host and MPA Modbus map. The mapping allows the Profibus DP host to control the Flow
Selector and monitor the actuator status. The control information is mapped directly to words in the Profibus Output
data and status information is mapped directly to words in the Profibus Input data.
