Configurable inputs
The SIL-B has eight digital inputs that can be configured by the user. The inputs can be configured
from the HMI or through the SICom program.
Firstly, we will define the concepts of physical input and logical input. Physical inputs are the
equipment’s real inputs. The SIL-B has eight physical inputs: Input 1, Input 2, Input 3,... up to
Input 8. These physical inputs can be associated with the logical inputs. The SIL-B has the
following logical inputs:
Logical inputs
Description
Input 52 a
Circuit breaker contact a
Input 52 b
Circuit breaker contact b
50P block input
Function 50P1 and 50P2 trip lock
50N/G block input
Function 50N/G1 and 50N/G2 trip lock
External trip input
External trip start. If a pulse of more than 20 ms is received (to avoid
false signals), a 200 ms pulse is generated to be used in the trip
output.
Fault init Input
Oscillography Start
79 init input
Start of 79 through external protection
Permission 79 input
Permission to close 79
Locking 79 level input
Lock of 79 through a level input
Input-1 Table Active
Active table assignment
Input-2 Table Active
Active table assignment
Locking 79 input pulse
Lock of 79 through a pulse input of an RTU
Unlock 79 pulse input
Unlock of 79 through a pulse input of a RTU
50BF init input
Start of circuit breaker fault through external protection
The inputs are configured by associating the logical inputs with the required physical input, or to
none if the logical input is not used. Therefore, a single physical input can be assigned to more
than one logical input.
