If you don't see I 0 on when you go online with the PLC then you have a wiring problem with your input. If a Set coil latches, then it means the input flickered on so rapidly that you couldn't see it.

Did you go online with the PLC and see that I 0 and O 0 were energized when the input signal is on?

If this isn't working for you (see attached), then post your code.

This doesn't appear to have anything to do with Unitronics products. If it does, please respond with more info. Otherwise I will delete the post shortly.

Is this Vision or UniStream?

I've seen power spikes or glitches change timer values. If you keep having the problem due to some electrical interference, you might try loading the timer preset into an ML and storing it back at the appropriate time.

You have your laptop set to the same IP address as the PLC. That won't work.

Maybe I wasn't clear. If you want help, you need to address every item that DanT mentioned - not just the last one.

It would be helpful if you addressed the troubleshooting comments when you respond. No one can help you if we don't know your situation. @DanT was kind enough to type all this out. Please let us know that you've gone through each of these on the other laptop that you're now having a problem with.

Are you using the same computer for both VisiLogic and Remote Operator? If so, they would be using the exact same pathway and if one works, the other should too, but they both can't connect to the same port at the same time. If not, then make sure the Remote Operator computer (or phone) is on the same subnet as the PLC. What I find is that my router hands out addresses to wired and wireless (wi-fi) with different subnets.

Did you fix the problem with MB 102?

It's very difficult to determine where the problem is from a few screen caps. Attach your program here and someone will take a look.

When you store MI 100 to MI 500, you are only storing the single register. For a vector, you must use Vector Copy.

I never store ASCII characters in ML, only MI. Why are you trying to use ML? Your attachment isn't making any sense to me. You show the column "Proizvod" to be defined as 10 characters, but in your Write Row FB, it shows as 20. Are they referring to the same Data Tables?

What function are you using to write the ASCII string? Typically, if the column is defined as String, 10, it will automatically read a vector of 5 MIs into the column. Make sure your Data Table definition is correct.

You cannot have initialization and configuration function blocks directly attached to the left ladder rail (your ladder rung 2). Do NOT do that. Use SB 2 to activate those. Also in ladder rung 3, you are resetting MB 10 when you should be resetting MB 9 (and MB 9 in rung 2 should be a Set coil, not a direct coil).

Allow me to repeat.

Oh, I see that you are initializing the ethernet continuously (MB 102 direct contact). Don't do that. Use SB 2 to initialize.

Socket 1 defaults to Port 20256. Unless you are using more than one socket, leave out the Socket Initialization so that you don't inadvertently have more than one socket assigned to the same port number. In addition to the great suggestions by @DanT, use a crossover cable if you aren't using an ethernet hub or switch.

Just draw two lines in Paint, or your favorite graphics program, save them to bitmap files, and assign them to the binary image switch.

Use Binary Image/Switch, or whatever it's called in UniLogic (that's the name in VisiLogic, but it's similar in UniLogic).

I lose track of all the different models, but is one regular Vision and the other Enhanced Vision? That may be the actual reason rather than the one stated in the error message.

I have a customer with some equipment controlled by a V1210 PLC with a bunch of I/O attached. This equipment is in the middle of nowhere and the 110V power is a bit iffy. There seems to be frequent voltage spikes or other glitches that often cause the PLC to lock up (power cycling brings it back with no problem). They have a UPS, which does keep things powered up, but doesn't seem to block other kinds of glitches. Anyone have a recommendation for high quality power conditioning for 110V?

Anyone ever use this function? I think it's very useful for backing up the software and updating without having to walk through the INFO Mode menus. I prefer to lock out INFO Mode (Set SI 50 Power-Up to zero) anyway so someone doesn't accidentally end up there by holding their finger on the screen too long. One question I have is that the Help file specifically says to use a NEGATIVE Transition to activate the function? Why do they say that? I like to set up a button that you have to press and hold for several seconds to activate the function and the best way to do that is to activate a Delay Timer with the button press and use a POSITIVE transition of the delay timer to activate the SD function. I tried that and it works fine. So what's the deal?

Did you try using the SD Utility: Delete SD File?
