Use the following steps to view the status of an analog output.
Use the navigation keys in order to select "VIEW" at the main menu screen. Refer to Illustration 1.
Illustration 1 g02270495
Press the "OK" key.
Use the navigation keys in order to select "I/O STATUS" at the view screen. Refer to Illustration 2.
Illustration 2 g02270496
Press the "OK" key.
Use the navigation keys in order to select "ANALOG OUTPUTS" at the I/O status screen. Refer to Illustration 3.
Illustration 3 g02270497
Press the "OK" key.
The status of each analog output is shown in Illustration 4. A "dash" under an output number indicates the output is programmed, but is inactive. A large "X" under an output number indicates the output is disabled. A number under an output number indicates the output is programmed and is active.
Illustration 4 g02270499
Use the navigation keys in order to select the desired analog output that is to be viewed. Press the "OK" key.
The settings that have been configured will be displayed. Illustration 5 shows the settings for usage type, range, minimum data and maximum data of the selected analog output.
