Response time

Table 5-12 Calculating the response time

Shortest response time	Longest response time
-	Multiply the physical cycle time by factor 2.
Now add I/O delay.	Now add the I/O delay plus the DP cycle times on
	PROFIBUS-DP or the PROFINET IO update
	times.
The result is the shortest response time.	The result is the longest response time.
