David Zárate Posted July 29 Report 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 Posted July 29 In your ladder you must add Set Info Password FB, then download the project. Change the value to any desired value.

MVP 2023 Flex727 Posted July 29 MVP 2023 Report Posted July 29 Did you power cycle the PLC after downloading the new program?
MVP 2023 kratmel Posted July 29 MVP 2023 Report Posted July 29 Default Info password =1111. Maybe 2222 (or other not 1111) must be set in MI4?
David Zárate Posted July 29 Author Report Posted July 29 Like this right?, i've tried to use the Info Screen and press the button Factory Boot from the Software Tab but still the same

MVP 2023 Ausman Posted July 29 MVP 2023 Report 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
Rick Bovensiep Posted September 22 Report 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
MVP 2023 Joe Tauser Posted September 22 MVP 2023 Report Posted September 22 2 hours ago, Rick Bovensiep said: Why did this function change? 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.

Change the value to any desired value. Apologies to drum up this old thread. Where the hell do you find the Set Info Password FB? I scoured the FB's list and can't find it. Apologies, I'm pretty new to this. V9.8.95 if it matters. Thank you!
MVP 2023 Joe Tauser Posted October 28 MVP 2023 Report Posted October 28 It's not in 9.8.95. That function was introduced in 9.9.0. If you're using 9.8.5 you shouldn't need it, but if you want to change the INFO password you can STORE a new value to SI 253. Joe T.

You won't find it in any 9.8 or before version as it isn't needed - you can set the INFO Mode password via SI 253. Edit: Joe types faster than me.

I went ahead and entered 1111 into the stored/start up value for SI253, did a download, and the V1210 is still saying "Stop reasons: No INFO password". Is there another FB or configuration that needs to be put in for it to work? Apologies, I know this is day one stuff. Edit: actually is just changed to PCOM request as the reason... will continue to investigate.
MVP 2023 Flex727 Posted October 28 MVP 2023 Report Posted October 28 The O/S in the PLC is for version 9.9 and it is checking the INFO Mode Password. You can try changing the password in SI 253 to something other than 1111 or any 4 consecutive numbers. Any 4 consecutive numbers are disallowed. I'm not sure if that will work though. Your other options are to downgrade the O/S to 9.8.95 from VisiLogic or download VisiLogic 9.9.01 and use that.

I didn't realize we may have been using this PLC to test out the latest software version, and in doing so might have upgraded the firmware. I'm assuming we can't roll back. But not a big deal, we'll be doing a plant-wide upgrade soon. Really appreciate it, thanks man!!
MVP 2023 Flex727 Posted October 28 MVP 2023 Report Posted October 28 20 minutes ago, JohnnyChimpo said: I'm assuming we can't roll back. Yes you can, but you must select the files manually in VisiLogic.

MVP 2023 Flex727 Posted October 28 MVP 2023 Report Posted October 28 Hey @Joe Tauser, where'd you put that tip jar? 😆
TODDSTER Posted October 28 Report Posted October 28 I am using v9.9.1 and in the HELP Menu under INFO Mode, it shows using 3333 (consecutive numbers). Has anyone confirmed that consecutive numbers will or won't work?
MVP 2023 Joe Tauser Posted October 28 MVP 2023 Report Posted October 28 Yes, we have confirmed the example in the Help does not work. The numbers can not all be the same. This has been brought to Unitronics' attention. Joe T.
MVP 2023 Ausman Posted October 28 MVP 2023 Report Posted October 28 Johnny, please also have a look at this topic, particularly my repeat at post 3 of something I've written elsewhere on the forum. https://forum.unitronics.com/topic/667-how-do-i-update-an-os/ And yes...God was very wise sending us to Unitronics land. 🙃 cheers, Aus

I put in a network card this morning and unplugged the PLC from power. Now it is saying "No PCOM Password". I tried to change the info pw, cleared the info password, etc all to no avail. Do you happen to have any info or detail on how to roll back the firmware on the PLC? Currently running 004.013.26 (or at least that's what the controller is showing)
JohnnyChimpo Posted October 30 Report Posted October 30 Never mind. Like an idiot, I assumed that the "Install Operating System" upgrade was connecting to the internet for the latest version, not the version that is in the visilogics software itself. My apologies. Thank you all!!
