DirectSOFT 6 Programming help needed

I'm hurting here and really need help.

I have an old machine running a AutomationDirect PLC 405. I have a data collection system that is successfully gathering data from this PLC, and from the KEPWare OPC Server I have been able to gleam from the KEP tags the various PLC Memory addresses. Many appear in DirectSOFT XRef View and in the Ladder. However, there are a range of tags -> addresses that do not appear in the XRef, or in the Ladder - I have tried multiple times to search for these tags, but cannot find any of them (V4120-V4133, V4140-V4153, and V4160-V4173) Many of these are updating on the Data Collection, but I cannot figure out how the PLC is interacting with these memory addresses - turns out at least a couple of them are swapped and I need to make sure the numbers are good in the PLC. I am relatively new to DirectSOFT 6 and AutomationDirect hardware in general. Please, help?

There are 961 rungs in the one ladder program. [neutral] Yes, I drew the short straw. [mad]

I haven't messed with that model but I wanted to point out that in other models the addresses that you communicate externally with them are sometimes different. If I recalled you added a zero or two to the ends of the addresses. Could this be what you're seeing?

Also:
Hey, one of the points of Automation Direct is the GOOD free tech support. This isn't scummy Allen Bradley or Schneider or Siemens where they want your credit card number before they dine to give you crappy service.

I called AD last week with a problem and they answered it intelligently in 90 seconds.
