The reaction time of MICROMASTER4 with respect to PZD is approximately 20
milliseconds.
This represents the period of time between "setpoint arrives at DP slave" and
"updated (and referencing) actual value is made available on PROFIBUS-DP“.
The reaction time of the MICROMASTER4 with respect to a parameter modification
(PKW) is approximately 50 milliseconds.
