Digital output test
Figure 113: Menu ‘Test Digital Outputs’
The list shows the digital outputs (DO) that are available on the
digital I/O modules installed in the device, see
Digital I/O
module
on page 97.
They are designated according to the installation locations of
the digital I/O modules (X20, X22, X24, X26).
Test:
1. Disconnect the plug with the connected signal lines from
the Digital I/O module.
2. Select the digital output to be tested with  or  .
3. Call up the value change using  .
4. Change the displayed value with  or  , and confirm the
change by selecting
OK
.
Result:
The relay at the digital output is switched, the status
indication changes from ‘OK’ to ‘Test’ and the ‘Function
Check’ status signal is set.
5. You can either test another digital output or reset the
tested digital output in the same manner.
The digital outputs test is terminated by pressing the
 button
or after approximately 5 minutes by the time-out function, which
resets all digital inputs to the ‘OK’ state and deletes the
‘Function check’ status signal.
Test of analog outputs
Figure 114: Menu ‘Test Analog Outputs’
The list shows the analog outputs (AO) that are available on the
analog output modules installed in the device, see
Analog
output modules
on page 96.
They are designated according to the installation locations of
the analog output modules (X20, X22, X24, X26).
Test:
1. Disconnect the plug with the connected signal lines from
the analog output module.
2. Select the analog output to be tested with  or  .
3. Call up the value change using  .
4. Change the displayed value digit for digit with  or 
and confirm the change by selecting
OK
.
Result:
The current signal at the analog output changes its value,
changes the status indication from ‘OK’ to ‘Test’ and sets
the ‘Function check’ status signal on the analog output.
5. You can either test another analog output or reset the
tested analog output in the same manner.
The analog output test is terminated by pressing the
 button
or after approximately 5 minutes by the time-out function, which
resets all digital inputs to the ‘OK’ state and deletes the
‘Function check’ status signal.
