Transmission rate
The transmission rate v
D
represents the number of characteristic states v
S
that are transmitted
within a step (transmitted signal values within a time period T).
v
D
= m · v
S
· log
2
(n) in bit/s
• v
S
= step rate
• m = number of transmission channels
• n = number of characteristic states
Value status
The value status is additional binary information in a digital input signal. The value status is
entered in the PII at the same time as the process signal, and provides information on the validity
of the input signal.
