Trying to get hypertrend to display signals

I created a series of multistate type objects to display limit switch positions. Each display is a green light for on, and black for off. Each one is displaying the status of a bit-of word, like DL2.V17051:2 for instance. I used the database to save the logical status, and tried to get it to log to the hypertrend with no success. If I do the same thing using a C type contact, it will show up. Why can't I do this?

How do you set the logging for logical status? This is what I do.

I use the Modbus. Connect the 40001.1 to a multistate object. It works fine. The logging is configured in modbus object. Then, create the Hypertrend, the URL is Modbus1.40001.1. The logical trends displays well like this attachment.

 

You can check if the data is logged or not by MAX. Create the trend view in MAX.
