PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Usage examples:
When the Open State is set to Pull-Up, and the Active State is set to Low, switching the input to ground (B−) will be seen in VCL as the switch is ON
When the Open State is set to Pull-Up and the Active State is set to High, switching the input to ground will be seen in VCL as the switch is OFF;
note that opening the input or pulling the input to B+ will be seen as ON
When the Open State is set to Pull-Down and the Active State is set to High, switching the input to B+ will be seen in VCL as the switch is ON; note
that opening the input or pulling the input to ground will be seen as OFF
When the Open State is set to Pull-Down and the Active State is set to Low, switching the input to B+ will be seen in VCL as the switch is OFF; note
that opening the input or pulling the input to ground will be seen as ON
One input, two operations example:
; Reach-in and Reach-out = switch (SW7), congured as Open State = Pull-down and Active Level = High.
If (SW7 = OFF) ; Reach Switch is open. Or the wire is off (broken) at the input (fail safe = Forks In)
Driver_5_Command = 0 ; Stop the fork Reach Out driver (Driver 5)
Driver_4_Command = 1000 ; Force the forks in, Reach In driver (Driver 4) is ON. 1000 = 100% PWM
If (SW7 = ON) ; Reach Switch is closed (switched the KSI)
Driver_4_Command = 0 ; Stop the fork Reach In (Driver 4 = OFF)
Driver_5_Command = 1000 ; Reach Out active (Driver 5 = ON) is ON. 1000 = 100% PWM
SW9
Status
Switch_9
0x3393 0x00
0 – 1 (Off/On)
0 – 1
Read Only Switch 1 status: On = 1 or Off = 0 (pin 32)
Same as in monitor: Monitor » Inputs » Switch Input » Switch 9
Note: This pin (32) can be used as the PWM Driver 9 (see Figure 4)
Open State
Switch_9_Open_State
0x31F9 0x00
Pull Down/Pull Up/Float
0 = Pull-down
1 = Pull-up
2 = Float
Pull Down
0
Selectable Pull-down or Pull-up input. This input can also be set
to a oat state, utilizing neither the pull-up nor the pull-down
circuits. The input impedance is as noted in Chapter 2, Switch
(digital) Inputs.
Active Level
Switch_9_Active_Level
0x3209 0x00
Low/High
0 = Low
1 = High
High
1
Set the active state of the input, whether low = On or High = On
0 = Low, 1 = High
Debounce
Switch_9_Debounce
0x3219 0x00
0 – 1000 ms
0 – 1000
0 ms
0
Length of time that the switch state must be steady (active)
before it is declared (valid).
The on and off state of the switch is de-bounced before
being presented to VCL. This parameter sets the length of the
de-bounce time. Each de-bounce period is 1 millisecond.
SW10 through SW12: X = the Switch Number, which is part of the VCL parameters’ name (see SW9 as the example)
Status
Switch_X
Variable’s CAN Index by Switch No.
10 = 0x3394 0x00
11 = 0x3395 0x00
12 = 0x3396 0x00
0 – 1 (Off/On)
0 – 1
Read Only Switch 1 status: On = 1 or Off = 0
Same as in monitor: Monitor » Inputs » Switch Input » Switch X
Note: This switch’s pin can be used as the PWM Driver
(see Figure 4)
Open State
Switch_X_Open_State
Parameter’s CAN Index by Switch
No.
10 = 0x31FA 0x00
11 = 0x31F6 0x00
12 = 0x31FB 0x00
Pull Down/Pull Up/Float
0 = Pull-down
1 = Pull-up
2 = Float
Pull Down
0
Selectable Pull-down or Pull-up input. This input can also be set
to a oat state, utilizing neither the pull-up nor the pull-down
circuits. The input impedance is as noted in Chapter 2, Switch
(digital) Inputs.
