PROFIBUS communication errors

In PROFIBUS mode, the screen below is displayed, the P indicates data exchange is
happening.

This screen will only be displayed after successful implementation of Master Slave
communications, which always follow the sequence described below.

Data exchange

If data exchange is lost at any time, the following screen will be displayed. The first red dot
corresponds to the stage at which the error occurred and subsequent stages will indicate a
red dot because the communication sequence halted before this point.
