Profibus DP Reduntant Networks with Redcom
The MPA uses CAM20 to convert between Mosbus 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.
