these extensions:

DP-V1 Master Class 1 (DPC1)
With DPC1, a cyclic DP master can also send or read slave data and receive and
acknowledge alarms. These data are not process data but slave-specific additional
data (for example, new parameters). These data are not sent cyclically and must
be acknowledged explicitly by the slave.
