Digital I/O Setting
Digital Input Lines
Input 1 Active Level Overridden By Operating Mode
It allows selecting the active state of Input 1 (External Trigger).
NOTE
This parameter setting is not valid, if the input has already been defined in On Line Operating
Mode or Code Verifier.
Selections:
Active Closed
Input 1 is active when current flows through I1A and I1B pins.
Active Open
Input 1 is active when there is no current flowing through I1A and I1B pins.
Input 2 Active Level Overridden By Operating Mode
It allows selecting the active state of Input 2.
NOTE
This parameter setting is not valid, if the input has already been defined in On Line Operating
Mode or Code Verifier.
Selections:
Active Closed
Input 2 is active when current flows through I2A and I2B pins.
Active Open
Input 2 is active when there is no current flowing through I2A and I2B pins.
Debounce Filter (ms)
Sets the maximum duration of the pulses which are rejected by the anti-disturbance filter. Pulses exceeding this limit
are recognized as valid commands.
Selections:
5 to 1000 (ms)
Digital Output Lines

Selection:
Local
The
scanner
drives
the
output
line
depending
on
the
activation/deactivation events.
External Fieldbus
The external Fieldbus Master drives the output line.
Line State
Allows the selection of the active state of the output.
Each output can be represented as an NPN transistor; this transistor acts like a switch: so, when the transistor is OFF,
it acts like an OPEN switch. On the contrary, when the transistor is ON, it acts like a CLOSED switch.
Selection:
Normally Open
the idle state of the output line is open, that is, the NPN transistor is OFF (like an
open switch). When the output is activated, the transistor goes ON (like a closed
switch).
Normally Closed
the idle state of the output line is closed, that is, the NPN transistor is ON (like a
closed switch). When the output is activated, the transistor goes OFF (like an open
switch).
