Yes, I get that, but perhaps the protocol or something else has an error that relates to baud rate in use, and the way to check is to run different ones to see if it changes something.

I'm addicted to drinking brake fluid, but I can stop whenever I want. What is Forrest Gump's password? 1Forrest1. (Still here? ok...here's more...) I have a side job making plastic Draculas. There are only 2 of us doing it, so I have to make every second count. What do you call a pony with a cough? A little horse. (Ok, you can go arrgghhhhh now! But there will be more...... 😉) cheers, Aus

I've been squizzing at the specs for that module, and a question is what baud rate are you using? Does changing the rate change the timings you're experiencing? Start low and speed up for the tests. And questions which might sound insulting, given it sounds like you know what you are doing..... Are the correct resistors in the correct place, and/or the unit's termination set correctly? Is the cable a quality one? cheers, Aus

I've got a few 130s and none have had a failure. But perhaps there is another element in play here. Nearly all the time my cards are not doing any actual "work" apart from maintaining, or trying to maintain, the connection. The only use is a daily login to check a few things, and other slightly longer times when there will be a program update etc. Vastly different to an installation that might be running the cards non-stop with large constant chatter between systems. So the question is whether the amount of card usage might heat things up too much? That is something I don't know and can't answer. Logically a device constantly doing "work" must generate more heat than if doing little, but perhaps not. And a side note on "duct" tape. I've mentioned this before but a repeat. "Duct" tape in Aus refers to a wider tape that is similar material to insulation tape. Invariably this stuff slightly retracts over time and leaves a horrible sticky residue on removal, especially when subjected to any heat elevation. If you are cutting squares of it to put over holes, it will likely not stay in place that well. The better thing to use is what we call "Gaffer" tape which is also known as Race tape and perhaps other names around the globe. It is cloth based and is much better for permanency in situations like this. The other alternatives for covering openings, which I've had to do sometimes after removing a card and not having a replacement "breakout" piece, are: 1). use a small cable tie to hold an external cover in place, with the tie run through dedicated holes or existing slots nearby. 2). tiny silicone dabs which are large enough to hold the cover piece, but small enough to enable ease of removal if needed. Over the years I've actually found that this is the best of the lot, but "needs must" applies at the time! cheers, Aus

I'm a Non-Unilogic user, but I agree with Joe that it sounds like a retry length issue, which can be a problem if not correctly set up to allow for the time errors take to run out of attempts on the current request before trying another. Are you sure that retries and numbers of them are being allowed for, or better yet for testing purposes, there are none? Perhaps there is a setting squirreled away somewhere that you have forgotten? Or don't know about? We all learn something new each day! 😉 Question for my learning...is this 485 or TCP? I don't know the table source due to not having Unilogic. If TCP, could the plc be dropping the ethernet connection for some reason, and it's not actually a modbus issue at all? If 485, bump the timeout UP a bit and see what happens. And also, is this involving the device that does addressing in hex? Just curious..... cheers, Aus

I think that before doing anything else, you need to use Info mode to find what O/S is in the PLC. This will then tell you what version of Visilogic you should be using at present for best compatibility. https://forum.unitronics.com/topic/5839-new-visilogic-version-to-what-os-list/ Once you have got all the info you want from the plc you could then update to latest. Please also read this to ensure that all is well with your actual installation of Visi: https://forum.unitronics.com/topic/7917-visilogic-doesnt-work-properly-after-installation-what-install-as-administrator-really-means/ cheers, Aus

I can't see why this would be too hard. Each of the 3 attempts is handled on it's own for display purposes, with it's own unique display based on the variables' maths. Then a fixed time after the attempt for the next one to happen for each participant. Then the over/under time averaging of their 3 attempts can be simply compared to the previous one to decide who is the current leader. If the previous one is better it remains as the leader, if the new attempt is shorter times, it replaces/updates the old details in the MIs which retain the data. At the end of the fun it gets the email entry, which is really the only thing I see needing a data table, perhaps routinely saved to the SD as a progressively named file. Of course this sounds easy, but I do think the reality won't be too hard to achieve, with very little head banging on brick wall/cursing/etc. I'm assuming that you'd simply put Remote Access or Operator onto a big screen nearby, to save any need for complex display conversions. cheers, Aus

Hmmmm...why not get the 1210 (or other unit) to perfectly time the gun shot, instead of teaching humans their failings? Seems a little roundabout to me.

In my use of modbus devices, I've never encountered this. All of them never mention hex numbers in their manuals for register work. If you do have a lot to work with for some reason, do an excel sheet that does the conversion for you. It's not hard.....HEX2DEC etc cheers, Aus

And now one for today's world..... Not so light hearted, but well worth a show.

Later Edit: I thought this was in Visilogic's area. Tired...sorry. But in some ways the fundamental idea might work for Uni. I don't use PID, but perhaps simply running the output through an intermediary MI that is stored, I would think that you could get a very close thing to what is wanted. Perhaps even holding the previous MI output value for a little while on restart until things stabilise a bit at around the stored output. I know this is my "simplified non-user" impression, but it might be worth a try. On the other hand, I might be talking absolute nonsense! cheers, Aus

In all of this have you ever consulted the various Help files, which show in detail how to do everything you've asked?

Looking at Merle's other posts I think you're right. Not enough initial info, and perhaps should have been started in the Unilogic software area.

Help...... Then...

For the moment with what you are trying achieve, I would not be using Version Swapper at all. If possible, try what Saragani has given you on a completely new installation of Visilogic 9.8.96 on a PC that has not had any Visilogic installation at all, or one where all Visilogic references (including version swapper etc) have been completely uninstalled using something like Revo Uninstaller or similar. cheers, Aus

Was this unit accessible via ethernet from the web?

Given you have works done on the more modern version, I would stick with it as you will likely have issues going backwards, although they may be minor. You need to work with official support to resolve the "non-admin" .exe issue not arriving by gmail, which is your simplest solution. Joe has suggested the ways around this.

Have you contacted support like I suggested? Please remember that this forum is NOT official Unitronics support, it is the forum for users and is mostly moderated by volunteers. Your question is best answered by support.

My answer in the original language post.

In many ways your best option is to directly contact Unitronics. Admin has been needed for some time. Either use the link above https://support.unitronics.com/index.php or email support@unitronics.com cheers, Aus

I edited this screenshot slightly to remove unrelated video feeds (like news services love to punch at you) and the result is actually still genuine. I'm thinking it was a Freudian slip...... or one of the journo's workmates pulled a swifty.

Benito, the direct answer to your question is NO. If I try with the programming tool, the PLC hangs. But....you can get around this issue by having an onsite PC with serial port as an intermediary connection. Your factory floor people could have a laptop they carry round, they plug in the serial connection and you do the rest by accessing the PC via wifi using a VNC. Please also have a look at this topic to get an understanding of what Flex is saying: https://forum.unitronics.com/topic/7245-dont-update-just-because-you-can/

With your PLC being a 130, I respectfully disagree with Flex saying you can update firmware by ethernet. Software yes, Firmware no. As far as I know, unlike higher level Vision controllers, you cannot update a 130's OS via ethernet, it has to be done via the serial port. It will start, but then fails and the plc is left in limbo. To do this is not a usb cable, it needs a proper serial port on the PC using the correct PLC adapter and cable. If the PC serial port is achieved using a usb to 232 adapter, the adapter has to be based on a Prolific chip. As for your 130s losing OS, I would be looking at two things. 1). Electrical interference. Shielding and correct elimination of spikes from coils, contactors etc has to be done. 2). If you already have ethernet connections to the 130s and they are accessible from the internet, then I would immediately change the default port(s) to something else. It is very possible that what you are experiencing is due to hacking attempts. If you can do so, update to the latest Visilogic version for better security and be prepared that you might need to change your program a little due to the upgrade. cheers, Aus

The Help system is your friend, along with doing simple trial and error learning. To fully understand something new, work on that one concept alone as a project until you fully understand how it works and can then relate it to your other needs. At present I would also have a good read of everything HMI related in Help, and also some other things that are important to know with regards to how the scan proceeds and can actually take a few scans to settle HMIs, in Program Sequencing: Modules, Subroutines, Labels & Jumps. (copy that into Search and it should be the 2nd topic). With single calls it is very easy to muck things up if other ladder elements have not got to where you think they are! Sometimes a relocation in the ladder is all that is needed. I often use a Negative Transition Contact for using the physical button pushes on 130s (ie no touch screen) and this inherent delay is useful. Everyday you learn something new. cheers, Aus

Perhaps it would be useful at present to try and monitor the strings, change things and find the successful resolution by using a PC, like I often suggest for getting around modbus 485 issues. It is far easier to manipulate strings/sends etc on the PC, and then once the correct one is found for what is wanted, transfer it to the PLC. I am likely showing my ignorance as I don't use can-open, but I know you can get usb canbus converters that can then be monitored easily, and a quick goggggles showed many programs available. Perhaps there are other easier methods as well....but I would think that you at least need an actual interface/device on the PC. Can you use a native serial port somehow? I don't know. cheers, Aus
