Commissioning / Configuration
The interruption is indicated by "LNK_MIS C" at coupler EK1100.
The EtherCAT ring is expandable. The number of devices in the ring is controlled by licenses: up to 250, up
to 1000, more than 1000. A master is only able to bridge one failure. In the event of two failures the ring
components will continue to run up to the breaking points.
4.2 Switching on and off
Switching on
The power supply for the basic CPU module comes from the power supply unit. The basic CPU module
starts automatically when the power supply unit is connected to the mains.
Switching on for the first time
When you switch on the PC for the first time, the preinstalled operating system (optional) will be started.
Switching off
The Embedded PC switches off when the power supply unit is switched off. The control software typically
running on Embedded PCs should be shut down or stopped correctly. A user who may not close software
may also not switch the Embedded PC off, since data can be lost from the hard disk by switching off while
software is running.
Once the software has been stopped, the operating system can be shut down. Only then should the power
supply be interrupted.
