Function of a digital output (Page 44)
in operating mode "Use count value
as reference"
Meaning
Additional option-specific pa-
rameters
After set command from CPU until
comparison value
When a set command is sent from the CPU, the
respective digital output is active until the counter
value is equal to the comparison value.
• Comparison value 0
• Comparison value 1
• Count direction
• Hysteresis (in increments)
Use by user program The respective digital output can be switched by
the CPU via the control interface (Page 43).

Note
DQ0 of a counter of a Compact CPU
With a Compact CPU, the
respective digital output DQ0 is available via the feedback
interface, but not as a physical output.
Note
You can only select the "Between comparison value
0 and 1" function for digital output DQ1
and only if you have selected the "Use by user program"
function for digital output DQ0.
Note
The "At comparison value for a pulse duration" and "After set command from CPU until
comparison value" functions only switch the digital output in question if a count pulse
reaches the comparison value. When the counter value is set, e.g. by synchronizatio
n, the
digital output does not switch.
Function of a digital output
(Page 52) in operating mode "Use
measured value as reference"
Meaning
Additional option-specific pa-
rameters
Measured value >= comparison
value
(default)
The respective digital output is active if the meas-
ured value is greater than or equal to the compari-
son value.
• Comparison value 0
• Comparison value 1
Measured value <= comparison
value
The respective digital output is active if the meas-
ured value is less than or equal to the comparison
value.
• Comparison value 0
• Comparison value 1
Between comparison value 0 and 1 The digital output DQ1 is active if:
Comparison value 0 <= measured value <= com-
parison value 1
• Comparison value 0
• Comparison value 1
Not between comparison value 0
and 1
The digital output DQ1 is active if:
Comparison value 1 <= measured value <= com-
parison value 0
• Comparison value 0
• Comparison value 1
Use by user program The respective digital output can be switched by
the CPU via the control interface (Page 43).
