Something scary is happening with our application on the EZTouch panels, PLC addresses on the numeric entry boxes are being changed, whenever the user enter a value in one field it overwrites another value on the PLC. It doesn't happens all the time but often enough to be noticed, usually after a "Driver can't access adapter Shared RAM " message is shown. No communications problems seen to be the problem and the panels where working ok before, the database has been modify recently, I wonder if this could be the cause (?). Have anyone else seen this kind of problem in EZTouch panels?

I forgot, the values are exchanged always between the same registries, for example V1616 overwrites V1624, and V1574 overwrites V1600. The PLC logic has been checked, theres absolutely no way that those values can be exchanged for the PLC, the problem is on the panel side.

Are you using Host's ECOM card in the EZ-Touch? (EZ-ETHERNET)

We are using EZ-ETHERNET and H2ECOM-100, the firmware versions for both of them are up to date. The ECOM is serving three (3) EZ-Touch 10,10 and 15 " and one (1) OPC Kepware DirectServer. Timeouts in panels and ECOM over 500 ms and 5 retries, OPC request 3seg. Panels have additional 512KB memory RAM and Flash. Network connections are correct, no problem with neither switch nor cables, distance from module to panels under 60 feet. Same problem for all the three panels. We tried clearing the panels, turned them off, removing the EZ-Ethernet and mounting it again, retransfering the application. Panels seemed to be working ok, we didnt make mayor changes just removing and adding some tags to the database.

You must change your PLC comm setup to communicate via Module # and not IP address within EZ-Touch. I had this problem before, took forever to figure it out. Hope that works for you.

Hi,
I changed the address mode to MODULE ID as you suggested but unfortunately it did not make any difference, the HMI still behaving very bad changing registries. I sent both PLC and HMI programs and all the information I found useful to the AutomationDirect team hoping they can give me an answer soon.

V1616 overwrites V1624, and V1574 overwrites V1600
Aparilli,
Does v1624 occur anywhere on your touch screen. How about v1600? If so, try changing those objects to a different v-mem location. Now see if v1616 still overwrites v1624 and so on. Or if it changes the new v-mem you created for that object.
