WARNING
If the 24 V voltage supply for an SCI slave fails which data are being exchanged between the
SCB1 and an SCI, then the "1" signal applied at a binary input is sent to the SCB1 or
SIMOREG as an "0" shortly before the power finally fails.
In contrast, the "1" remains applied in the SIMOREG in the event of an interruption in the fiber
optic connection.
If an external voltage (logical "1") has already been applied to a binary input when the electronics
supply voltage is switched on, this status will not be registered until the external voltage is
disconnected and reconnected again.
