Timing and runtimes

5.3.1

Overview

The Power Line Booster system implements a transparent transmission of Ethernet frames

via powerline. In addition, it ensures optimum utilization of the media with regard to real-time

capability of IO data.
To do this, the PLB master runs the PLB cycle in which it contacts each accessible PLB

slave one after the other; it also synchronizes the PROFINET IO data of the automation

components connected downstream from this PLB slave. It also transmits Ethernet packets

of other protocols, if present, but only so many that the normal PLB cycle time is not

exceeded.

5.3.2

Configuring the PROFINET update time

You should set the PN update time somewhat shorter than the average PLB cycle time of a

full segment. This ensures that the current PROFINET IO data is transferred with each PLB

cycle.
The PLB cycle time is the time that a PLB master needs to contact the currently registered

slaves once and to exchange data with them.
The PLB cycle time of a master depends on the number of slaves in the segment. For the

average cycle time, we only want to consider the case when no vehicle enters or exits the

segment.
The master needs about 2.3 ms for the data exchange with each slave. In addition, the so-

called registration phase (Hello Phase) (see section "Traffic Manager time configuration

(Page 95)") of about 5 ms is added at the beginning of the cycle.
This means the PLB cycle time can be calculated as follows:
PLB cycle time = (number of connected slaves • 2.3 ms) + 5 ms

Table 5- 3

The dependency between the number of slaves, PLB cycle time and PN update time is

listed in the following table

Number of connected

PLB slaves

Average PLB cycle time

Recommended PN

update time

40 • 2.3 ms + 5 ms = 97 ms

64 ms

20 • 2.3 ms + 5 ms = 51 ms

32 ms

10 • 2.3 ms + 5 ms = 28 ms

16 ms

1 • 2.3 ms + 5 ms = 7 ms

8 ms

With the PDS application (two slaves per vehicle), the master only queries one slave

alternately per PLB cycle. This means that it is not the number of slaves per segment that

must be used for the calculation of the PLB cycle time but the number of vehicles.
