Symbol Animation
Symbols change, depending on the value of their inputs. A drawing corresponds to
each state. Animation occurs by changing the symbol each time the state changes.
Symbol inputs are assigned directly to the Sepam™ inputs to indicate the position of
the switchgear in the symbol.
Animated Symbols with Two Inputs
Animated - 2 inputs and Controlled - 2 inputs/outputs symbols are animated
symbols with two inputs, one open and the other closed.
This is the most common situation in representing switchgear positions. The symbol
has three states or three graphic representations: open, closed, and unknown. The
last is obtained when the inputs are unmatched. It is impossible to determine the
position of the switchgear in such a case.
Symbol Inputs Symbol State Graphic Representation
(Example)
Input 1 (open) = 1
Input 2 (closed) = 0
Open
Input 1 (open) = 0
Input 2 (closed) = 1
Closed
Input 1 (open) = 0
Input 2 (closed) = 0
Unknown
Input 1 (open) = 1
Input 2 (closed) = 1
Unknown
Animated Symbols with One Input
Animated -1 input and Controlled -1 input/output symbols are animated symbols
with one input. The value of the input determines the state of the symbol:
b input set to 0 = inactive
b input set to 1 = active
This type of symbol presents information simply, like the racked-out position of a
circuit breaker.
Symbol Inputs Symbol State Graphic Representation
(Example)
Input = 0 Inactive
Input = 1 Active
Symbol Inputs/Outputs
Depending on the desired operation of the mimic-based UMI, Sepam™ variables
must be assigned to the inputs of animated symbols and the inputs/outputs of
controlled symbols.
