11.2.4 Reaction to interruption of bus communication or failure of the DP
slave
Overview
11-10
The reaction to an interruption in bus communication or the failure of one or
more DP slaves depends on the error mode you selected with COM ET 200
Windows. The various possibilities are shown in the table below.
Note
If bus communication with a DP slave is interrupted, the DP slave fails or,
for example, the bus connector of the IM 308-C is pulled, there is a
possibility of the most recently received data losing its consistency.
The same applies when bus communication is reestablished or the DP slave
is again addressable.
Remedy: If you require consistent data, you must re-address the data.
