Example 2
11 on page 31 shows an example in which three modules with different acquisition rates are linked to each other. The transfer scheme for
this configuration is shown in Fig. 5

Transfer Scheme for Example 2 (Simplified, Not True to Scale)
In this example, the third module periodically generates 2
16
(65536) time slices (Ethernet frames) each 100 microseconds long. The ES400 mod
-
ules 1, 2 and 3 acquire measurements at a rate of 10 kHz, 2 kHz and 5 kHz. Module 1 links its measurements to each Ethernet frame, module 2 to
every fifth Ethernet frame and module 3 to every second Ethernet frame (bottom figure).
Independently of this, control variables can be transferred at the same time from the PC to the modules.
