Execution of this command causes the device to emulate a complete power cycle.
This includes an ESC reset. An SDP may limit some behavior of the power cycle
emulation, but shall not exclude the EtherCAT interface.
As consequence of an ESC reset all following devices are disconnected
from the network.
There are two versions of this command:
• Standard reset (as described above)
• Factory reset (as described above, but additionally, all parameters are restored
to as-shipped defaults).
