Safety diagnostics of safe AS-i inputs

Diagnostics in the IDI is a way of sending the key diagnostics functions to the
controller without a command interface (Mailbox) or any additional effort. The dia-
gnostics information is sent in the input data image, coded for the input bits of the
address of the safety input slave.
The switching state of Channels 1 and 2 of the safety input is shown with negli-
gible time lag in bits 0 and 1 and can be directly read:
Bit3 Bit2
X X
