Description of Function Block
1
0 0
0
The Boolean Function Block uses Boolean
2
P
O
algebra to control the ON/OFF state of an
3
output. An operational expression consists
B
L
4
of either the AND, OR, XOR or NOT form.
The Set/Reset Function Block either holds
0 0
0
an output ON (set) or releases the output
S
P
O
OFF (reset.) Priority can be given to either
R
input pin if both inputs have been energised
S
R
simultaneously. The default priority setting
is dedicated to the reset input pin.
The Pulse Function Block sends a single
0 0
0
pulse to the output pin if the input pin
I
P
O
receives either an "ON to OFF", "OFF to
ON" or "ON to OFF And OFF to ON" input
P
L
operation.
The Alternate Function Block is used to
0 0
0
reverse the ON and OFF state of the output
I
O
as and when the input pin receives a signal.
C
The output will be set ON when the input
A
L
pin goes high and remain ON until the input
receives the second rising edge.
0 0
0
The Delay Function Block provides an ON
delay timer and an OFF delay timer. Time
I
P
O
intervals for either situation can be set. The
C
time unit can be set to 10ms, 100ms or 1s
D
L
increments.
The One Shot Function Block awaits a
signal supplied to the input pin thereafter
0 0
0
setting the output according to the specified
I
P
O
time. The timing parameters control the
C
state of the output (depending on the
O
S
priority setting). The time unit can be set to
10ms, 100ms or 1s increments.
0 0
0
The Flicker Function Block changes the ON
I
P
O
and OFF state of the output according to a
preset flicker time. The time unit can be set
F
L
to 10ms, 100ms or 1s increments.
0 0
0
The Time Switch Function Block uses a
P
O
predefined time schedule to control the ON
and OFF status of the output.
T
S
The Time Switch maintenance Function
0 0
0
Block uses a predefined time schedule to
P
control the ON and OFF status of the
output. The function block can be setup
T m
S
from the TopMenu "Parameter" via the front
panel keys.
The Counter Function Block increments the
0 0
0
current value by one as and when the input
I
P
O
pin receives a signal. When the current
C
value reaches the set value the output is set
C
N
ON. The counter current value is reset as
and when the clear pin receives an input.
