9. Connection overview
This chapter shows some connection examples to give an idea of what combinations are possible and
what are the important limitations you need to consider before mounting the Dewesoft system.
When you set up your system you have to be careful about the system limitations, such as bandwidth
(maximum rate of data transfer), cable length between devices (power supply cable and ECAT cables)
and power consumption of devices.
We recommend that you calculate the Bandwidth of the system with our Dewesoft calculator, which
you found on our web-page. The recommendable upper limitation for Krypton ECAT devices is around
6Mb/s, if you exceed the maximum bandwidth you will need additional data (ECAT or USB) lines.
If the system needs very long cables between devices, the voltage drop is bigger consequently the
output voltage is smaller, which means fewer devices can be supplied in the further chain. If the system
requires a long power supply cable, you should consider using a thicker cable (e.g M10).
In the specification tables you can find a power consumption of each Krypton device and calculate
approximate consumption. You can also calculate the collective consumption with our EtherCAT
calculator (implemented in the configurator), where also a voltage drop on cables is taken into account.
If there isn’t enough PS for all devices, a power injector must be added in the middle of the chain.
