605C Frequency Inverter
Operation Description
NOR(A,B,C)
O
UTPUT
INPUT A
INPUT B
INPUT C
NOR(A,B,C)
If at least one of A or B or C is
TRUE then the OUTPUT is
FALSE, otherwise the
OUTPUT is TRUE.
XOR(A,B)
O
UTPUT
INPUT A
INPUT B
INPUT C
XOR(A,B)
If A and B are the same, (both
TRUE or both FALSE), then
the output is FALSE, otherwise
the output is TRUE.
0-1 EDGE(A)
input A
output
input C FALSE
input C TRUE
Duration 20ms
t
Rising Edge Trigger
Input B is not used.
This function outputs a pulse of 20ms duration when INPUT A to the block
becomes TRUE. When INPUT C is TRUE, the output is inverted.
1-0 EDGE(A)
input A
output
input C FALSE
input C TRUE
Duration 20ms
t
Falling Edge Trigger
Input B is not used.
This function outputs a pulse of 20ms duration when INPUT A to the block
becomes FALSE. When INPUT C is TRUE, the output is inverted.
