Actual signals and parameters
234
DO=1 Transistor output is energized (closed) and relay output is de-energized.
Analog output control is frozen to the previously set value. -0.2
RO=1 Transistor output is de-energized (opened) and relay output is energized.
Analog output control is frozen to the previously set value. -0.1
AO=0 Analog output value is set to zero. Relay and transistor outputs are frozen to
the previously set value. 0.0
0.1…100.0% Value written to signal 0170 SEQ PROG AO VAL. Value can be connected to
control analog output AO by setting parameter 1501 AO1 CONTENT SEL
value to 170 (i.e. signal 0170 SEQ PROG AO VAL). AO value is frozen to this
value until it is zeroed.
8424 ST1 CHANGE DLY Defines the delay time for state 1. When delay has elapsed, state transition is
allowed. See parameters
8425 ST1 TRIG TO ST 2 and 8426 ST1 TRIG TO
ST N.
0
0.0…6553.5 s Delay time 1 = 0.1 s
8425 ST1 TRIG TO ST 2 Selects the source for the trigger signal, which changes the state from state 1
to state 2.
Note: State change to state N (8426 ST1 TRIG TO ST N) has a higher
priority than state change to the next state (8425 ST1 TRIG TO ST 2).
NOT SEL
DI5(INV) Trigger through inverted digital input DI5. 0 = active, 1 = inactive. -5
DI4(INV) See selection DI5(INV). -4
DI3(INV) See selection DI5(INV). -3
DI2(INV) See selection DI5(INV). -2
DI1(INV) See selection DI5(INV). -1
NOT SEL No trigger signal. If parameter 8426 ST1 TRIG TO ST N setting is also NOT
SEL, the state is frozen and can be reset only with parameter 8402 SEQ
PROG START.
0
DI1 Trigger through digital input DI1. 1 = active, 0 = inactive. 1
DI2 See selection DI1. 2
DI3 See selection DI1. 3
DI4 See selection DI1. 4
DI5 See selection DI1. 5
AI 1 LOW 1 State change when AI1 value < par. 8412 SEQ VAL 1 LOW value. 6
AI 1 HIGH 1 State change when AI1 value > par. 8411 SEQ VAL 1 HIGH value. 7
AI 2 LOW 1 State change when AI2 value < par. 8412 SEQ VAL 1 LOW value. 8
AI 2 HIGH 1 State change when AI2 value > par. 8411 SEQ VAL 1 HIGH value. 9
AI1 OR 2 LO1 State change when AI1 or AI2 value < par. 8412 SEQ VAL 1 LOW value. 10
AI1LO1AI2HI1 State change when AI1 value < par. 8412 SEQ VAL 1 LOW value and AI2
value > par. 8411 SEQ VAL 1 HIGH value.
11
AI1LO1 ORDI5 State change when AI1 value < par. 8412 SEQ VAL 1 LOW value or when
DI5 is active.
12
AI2HI1 ORDI5 State change when AI2 value > par. 8411 SEQ VAL 1 HIGH value or when
DI5 is active.
13
AI 1 LOW 2 State change when AI1 value < par. 8414 SEQ VAL 2 LOW value. 14
AI 1 HIGH 2 State change when AI1 value > par. 8413 SEQ VAL 2 HIGH value. 15
AI 2 LOW 2 State change when AI2 value < par. 8414 SEQ VAL 2 LOW value. 16
