Cycle time
Figure 6-20 Cycle times (long-term measurement)
This page gives you an overview of the cycle times of the connected PLB master and its
slaves. The cycle time is the time that the master needs to query all connected slaves one
after the other.
You can find a general description of the tables in Status tables (Page 102).
The minimum, maximum and average cycle time of the master is displayed at the top of the
page.
The following columns are displayed by default in the table of slaves:
● "Connected on": Time at which the connection to the slave was set up.
● "PN name": PROFINET name of the slave.
● "IP address": IP address of the slave.
You can display the current position of the slaves via the "Position info" switch. However, this
value is only available if the current position of the PLB slave is transmitted via the
PROFINET IO interface.
● "Position": Shows the current position of the slave (only if this is transmitted via PN-IO
(Page 64)).
In addition, the following values are always displayed regardless of the switch position.
● "Poll Max": Maximum polling time (query time + response time) to a slave.
● "Poll Avg": Average polling time to a slave (typically < 2.5 ms).
● "Gap Max": Maximum time between two frames to one slave.
