PLC Crash help

I was testing a countdown timer on my PLC and entered data into a register I shouldn't have. I lost all connection to the PLC. Is there anyway to restore to factory settings? I'm using a Delta DVP32EHT2 with 4 analog in and 2 analog out module.

Try removing all battery power to the EPROMs. Let it sit a while to see if it resets. I'm not too familiar with Delta PLC's. Is the register retentive? You would think system registers wouldn't be accessible to the ladder.

I did exactly that powered down and unplugged the battery left it disconnect for 1 day for the capacitors to discharge. I have it all back running again. The register I wrote to were not listed in main factory register list. They basically changed my station address which shutdown communication. I'm currently working on my HMI and not really good with that type of thing. Do you know of any good examples I could look at. I'm using advanced HMI. Thanks for the help.

I was using advanced HMI to start off. It can be a pain since it is Microsoft based. Need to decide on a driver to communicate with it. If your PLC has MODBUS, that's how I would do it.

If you have some room in your budget, look at Automation Direct Cmore, the new EA9 line is very reasonable and stable.

I have good connection and seems to be stable when I don't enter data into places I shouldn't. I was actually referring to is the layout of the screen itself and functionality. I'm not real good with this type of creativity so wanted to look at some screen shots of others HMIs and get some ideas. I found this one here on HBT, but not many more that use Advanced HMI. As far as the budget it is about tapped out so for now I need of free HMI software that can be run using my laptop as the HMI screen.

I can email you my copy.
