David Zárate Posted July 29 Report Share Posted July 29 Hi everybody, im trying to use an Visilogic V570 for Modbus communication, when i tried to load a sample program it told me to update the firmware of the PLC, after the update it only shows this screen (Uploaded Image), i have tried the buttons: Init, Reset and Run from the "Connection" toolbar and when pressing run, it only changes the status from Idle to RUN/STOP conflict, how can i do a factory reset to the PLC or restore it to solve the problem? thanks in advance.

Gabriel Franco Posted July 29 Report Share Posted July 29 In your ladder you must add Set Info Password FB, then download the project. Change the value to any desired value. Link to comment Share on other sites More sharing options...

MVP 2023 Flex727 Posted July 29 MVP 2023 Report Share Posted July 29 Did you power cycle the PLC after downloading the new program? Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted July 29 MVP 2023 Report Share Posted July 29 Default Info password =1111. Maybe 2222 (or other not 1111) must be set in MI4? Link to comment Share on other sites More sharing options...

MVP 2023 Ausman Posted July 29 MVP 2023 Report Share Posted July 29 1 hour ago, David Zárate said: Like this right?, No, in your rung 1 change MI4 to something other than 1111. Power cycle means different things to people. After ensuring that you have sent your new program at least as a download all and burn, so you won't lose it through a reboot, do a complete power off, wait for 10 seconds, then repower on. cheers, Aus Link to comment Share on other sites More sharing options...
Rick Bovensiep Posted September 22 Report Share Posted September 22 I need some help. I'm not getting the INFO Password to work. Why did this function change? I'm trying to get this to work for a demo on Monday. If anyone can help, I'd be great appreciated CST Purge Control Center-with Auto-Purge.vlp Link to comment Share on other sites More sharing options...

Unitronics' response to the The Great Hacking of 2023 was to update the O/S so no defaults could be left in place. You can read about it here: https://www.bleepingcomputer.com/news/security/hackers-breach-us-water-facility-via-exposed-unitronics-plcs/ They also removed all previous versions of Visilogic from the download area of their website. You now must set the Info Mode password and if you have an Ethernet card you must set that password as well. In the attached file, I set MI 60 to power up to value 1255 and called the Set Info Password function with the power-up bit SB 2. The address of the MI is not important - I just picked an un-used one. The value of the password can't be four repeating characters. Let us know if it works. Joe T.
