Refer to Figure 16-2 to access and read the current states of Discrete Input 1 and 2. States are shown 
as:

•

Yes (ON)

•

No  (OFF)

To test the discrete inputs, toggle the remote input device and verify that the appropriate value is 
received by the Series 3000 device.

If the Series 3000 device has been wired for a frequency input, refer to Figure 16-2 to access and read 
the output level of the frequency input. The frequency is displayed in Hz.

To test the frequency input, check the frequency at the remote input device and verify that the 
appropriate value is received by the Series 3000 device.

If polling for pressure or external temperature has been configured, refer to Figure 16-2 to access and 
read the pressure and temperature values being received by the Series 3000. 

To test the pressure and temperature input, use a reference device and verify that the appropriate value 
is received by the Series 3000 device.

The software enables you to set the states of discrete outputs or the values of milliamp outputs or the 
frequency output.

Refer to Figure 16-2 to access and set the current states of discrete outputs.

1. Select the discrete output to be set.

2. The default setting is Unfixed. Reset the output to ON or OFF. The outputs associated with ON 

and OFF depends on the output’s polarity, as shown in Table 8-1. (For information on setting 
the discrete output polarity, see Section 8.3.1.)

3. Press 

 to set the state of the selected discrete output.

4. Check the receiving device to ensure that the correct level is being received.

5. Reset the discrete output to Unfixed, or exit to the Simulate Outputs screen. The discrete 

output is released and is again controlled by the application.

To avoid measurement error, set control devices for manual operation before 
performing output tests.
