In case of a "long message" being correctly transmitted and an acknowledgement
received, the DSL Master will wait for an answer from the DSL Slave. As the processing
time of a long message cannot be reliably predicted, there is no timeout implemented
in the DSL Master. To determine the time overrun for a "long message" transaction, the
user must refer to the time overrun characteristic in each individual resource of the DSL
motor feedback system (see chapter 8.2).
To be able to use the Parameters Channel again in case of a pending "short message"
or "long message" that is blocking the corresponding message channel, the user appli‐
cation must trigger a Message reset of the Parameters Channel (see chapter 6.3.1).
This reset does not affect position measuring or the transmission of position data. The
reset sequence for the Parameters Channel is specified in figure 28.
