Question: I forgot my password, what are my options?
Answer: If the password is lost or forgotten, you will have to return the PLC to AutomationDirect, to get the password cleared. The CPU contents will be erased when we clear the password, there is not a way to retrieve the project.

Contact Tech Support to get a Equipment Evaluation form to fill out and return with your PLC. Once AutomationDirect has the signed form and PLC, we can clear the PLC and return it back to you.

AutomationDirect can only perform the password clear if the PLC is being shipped back to a United States address, we cannot ship the PLC outside of the US.

FAQ ID: 1170
Question: How do I use a variable as a timer preset?
Answer: In your timer box where you are currently typing 'Kxxx' for the preset you would put a V memory address such as V2000. Make sure that this address is only used for this purpose. Now open a data view and type in V2000. You would use this same V memory address for every timer that you want to have the same value.


Click the yellow E button with the red circle and slash in the upper left of the data view window to enable edits. Now you should have a column titled edits on the right of the V2000 you typed in. Enter your value in this column next to V2000 and press the middle of the three buttons at the top right of the data view.


Please note that you can use other V memory addresses than V2000. The full list of available addresses is available in the PLC -> Memory map menu item. Also you can find the list of available memory in Chapter 3 (or 4 depending on the PLC model) of the User manual.
