At our plant, we use a C# script to communicate with the PLC over IP and monitor memory locations in order to trigger an email. I wasn't the responsible party, but if you're interested I can get the programmer to leave a comment here with more details.

Hi Mohammed, Perhaps you initially made your post in the Unistream forum, I see you commented there before. Flex simply moved your post to the Vision forum where it belongs, as you are using Vision hardware. Have you defined all of your modules in the hardware setup?

Thanks for the responses, Flex and Alex The problem seems to have resolved itself as of this morning, without any interference on my part. Perhaps IT did some updates over the weekend.

I've recently been experiencing trouble saving program files, I'm given the following error message Save Failed (174) Disk is full, or write protected, replace the disk and try again. Error number (507) The files I am working on are saved to my desktop. After I clear the error message it brings up a Save As window, at which point I "replace" the old file with the new file of the same name. Before this week, I've been able to save normally with no trouble. Been running 9.8.95 for a while now. I haven't been able to find any documentation on this error or mention of it in the forums, hoping one of yall might be able to offer some guidance.

Not possible with Visilogic, try searching for "ladder logic simulator"

I understand, thank you very much for your responses. The reasoning behind this was that I am trying to control a solenoid and two DC motors, with direction switching, using only the 6 relay outputs. Simplified to clarify, motor 1 may be controlled by outputs 0 and 1, then motor 2 may be controlled by outputs 1 and 2, so pressing one button would set Os 0 and 1 and another button would set Os 1 and 2. I have ended up just splitting the two functions into different sub routines, rather than controlling everything from one screen.

HI all I'm programming a project on a 1st gen V120 and wanted to confirm something about the relay outputs. I was attempting to write a program that could trigger a given relay output from more than one rung in the same module, but it appears that isn't allowed. For example, if a coil for output 1 is present in rung 1 and rung 2, then the coil for O1 in rung 1 is simply ignored. I can see some logic in not allowing this, but I found it strange that it doesn't trigger any error or warning if that was the intention. Could anyone confirm this for me?

That's exactly what I needed, thank you so much!

Currently working on a project that involves interfacing a V1210 with an EX-RC1 as part of a CANBUS network. The -RC1 has some timers on it which I would like to be able to configure from the V1210, but just noticed that the -RC1 does not have the option to "Store Timer Preset" from the Store dropdown menu. Am I SOL in this aspect?

Thank you very much, I'll try this out and see how it works for me. When the webpage goes down, SI145 gets stuck on 6, I might use that as a condition to reconfigure the socket after SI145 = 6 for long enough.

SB168 is initialized to 1, as well as being 1 while looking at the program in online mode. In my debugging attempts SI145 has caught my attention. With no web page open, SI145 sits at a value of 2. With one instance of the webpage open, SI145 will sit at 2 and flick up to 6 every 10 seconds (the length of the webpage refresh time). With multiple instances of the web page open on other devices, SI145 flicks to 6 every ten seconds for each instance that is open. The webpage was working fine when I got in this morning, so it seems like it only gets hung up when too many devices are viewing the webpage at once. It is easy to limit the number of people opening the webpage, but I am wondering if there is some way to bring the webpage back online without resetting the whole PLC.

Hi all, I've run into a reoccurring issue with a web page. I have a V1210 setup to contain remote inputs and have configured the web page to show a list of the analog values. It works great, just type in the IP and get those values remotely from the office. However the web page will occasionally halt, throwing a "web page took too long to respond" error. At this point it stays like that until I send the PLC a reset command. Is there some sort of time out feature or user access limit for the web service?

I get the same error when attempting to open a project restore point.
