Input and Output Signals
Input signal
HW enable
Output signal
Frequency on the digital
output DO
308
Meaning
Indicates an output sequence is
running.
Indicates the signal level at the
digital output DO.
Note the update rate.
Indicates the signal level at digital
input DI.
Indicates the status of
SW_ENABLE.
No function in this operating
mode.
No function in this operating
mode.
Meaning
You can select the HW enable
with the "Function DI"
parameter.
The signal of the digital input
DI is then interpreted by the
2PULSE at the start of the
output sequence.
The frequency is output on the
digital output DO.
Value range
0 = pulse output blocked
1 = pulse output running
0 = Signal 0 on digital output DO
1 = Signal 1 on digital output DO
0 = Signal 0 on digital input DI
1 = Signal 1 on digital input DI
0 = SW_ENABLE cleared.
1 = SW_ENABLE set
–
0
Value Range
0 = HW enable cleared
1 = HW enable issued
0 → 1 = Start of the output
sequence; dependent on the
software enable
0 = no pulse
1 = pulse
