No INFO Password

[RobertiKo]

Hello everyone, I am new to working with Unitronics PLCs and I have encountered the problem that after downloading a simple program, the system tells me that the PLC is in stop mode, because there is no INFO Password. I have reviewed a previous post here in the forum, I have tried the same solution and it has not worked. Can you help me? The PLC is a V570 with an I/O module V200-18-E3XB, IDE version 9.9.1. Thank you very much.

This problem is going to be with us for a while as people take applications that were working perfectly fine and then update their software to 9.9.0 or above.

Don't update your Visilogic if you're not a a network.

Further to what Joe is saying, if you aren't on a net and can  go back to the original version, you might have to delete/copy firmware info from the old version into the relevant folder in 9.9.1 to allow it to happen.  When I needed to go backwards I had to do this rearranging.  Once the firmware update (downdate?? ....back is not the opposite of up... 🙂) is complete and checks ok, uninstall 9.9.1, put your original Visilogic back in, and then download and burn your original vlp file.  If you don't know the old version, use Project/Project Information to find what it is saved as.  Or a good starting point is 9.8.65.

Lastly look at this:
