10 Time Characteristics
The two diagrams below demonstrate the time characteristics and the bus
load in dependence of the number of clients.
The measurements were done with an Ethernet bus analyzer. The analyzer
calculates the average bus load and the number of messages of the server.
The two diagrams that follow are the result of both measuring examples.
Example 1
Measuring Sys-
tem
Module Number of COM-E Modules Cycle Time
Server configura-
tion
ZS400 1 min. 65 ms,
max. 75 ms
Client controller 1 SK500
ZS500
5 Approx. 10 ms
Client controller 2 ZS400 5 Approx. 10 ms
Client controller 3 SK500
ZS501
5 Approx. 10 ms
All clients read a data module with 512 bytes from the server. The commands
are STOP- or EP-coordinated.
Example 2
Measuring Sys-
tem
Module Number of COM-E Modules Cycle Time
Server controller 1 SK500
ZS500
5
Client configura-
tion
ZS400 1 Approx.10 ms
The client continuously requests a data module with 512 byte. The server
controller is in the STOP state.
A reading command, 512 byte, lasts approximately 41 ms.
A writing command, 512 byte, lasts approximately 41 ms as well.
