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?
-
Blow away what data table?
You shouldn't need it for this, but SB 300 will perform a soft boot of the PLC.
-
I could be wrong, but my understanding is that Remote Operator and Remote Access are for the Vision line only. The UniStream uses VNC.
It sounds like you are trying to access the PLC while external to the network it's on. You must take certain actions in order to do that and I recommend that you consult with the IT professional that has responsibility for the intranet the PLC is on. This issue is unrelated to the PLC, but is common to every device that you might want to communicate with from the internet. One common method for accessing a PLC on an internal network from the internet is to use port forwarding on a router, though that is not the most secure way.

Use the "Binary Text / Switch" HMI element instead of a button.

I have successfully autotuned and run a PID loop without any I/O attached by varying the analog input by hand. The resulting PID values would not work in the real world, but I was able to test to make sure the PID loop was set up correctly.
The PID values can be calculated by the autotune process or you can enter them manually. You have either or both options available to you.
You don't need an oscilloscope to see analog output. Just go online and look at the MI operand attached to the analog output.
By the way, there are example projects that came with your VisiLogic installation that include an example for PID loops. Take a look at that and see if your PID is set up correctly.

Thanks Flex.
I'm not good for much, but I can spot typos!

I believe it's SMTP2GO (the number 2, not "to").

Some people have had success with SMTP2GO.

To my knowledge, Mail.com uses SSL. You cannot send email through mail.com using a Vision product.

Now stop wasting your weekend time on a dummy like me.
We're all dummies like this. You wouldn't believe how many times I've made a similar mistake. Usually it just takes a fresh set of eyes to spot it. We're happy to help no matter how simple the problem.

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.
