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. Yes, I drew the short straw.
