Function: Direct Control of the DO Digital Output

Definition
You can directly control the digital output DO of the 2PULSE to test the actuator you have
connected. To do this, you have to select the function from your control program with the
MANUAL_DO control bit set and with the SW_ENABLE control bit deleted.
After you have selected the function, the feedback bits STS_ENABLE and ERR_PULS are
deleted by the 2PULSE, and an active output sequence is canceled.
You specify the reset the status of the digital output DO with the SET_DO control bit.
When you delete the MANUAL_DO control bit, you deselect the function for the direct control
of the digital output DO. This deletes the digital output DO. You will then have to restart the
output sequence.

Meaning
To select the function, the control
bit must be deleted.
You can select and deselect the
function with the control bit.
You use the control bit to set the
status of the digital output DO.
Deleted after the function has
been selected.
Indicates the signal level on the
digital output DO.
Note the update rate.
Indicates the signal level on digital
input DI.
The status preset with the
SET_DO control bit is output on
the digital output DO.
Value Range
0 = SW_ENABLE canceled
1 = SW_ENABLE set
0 = direct control of the DO not
selected.
1 = direct control of the DO
selected.
0 = signal 0 on digital output DO
1 = signal 1 on digital output DO
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
Value Range
0 = no signal
1 = signal
