Hi, all. I have an L32E with 16.2 firmware. I set up the non-volatile memory to load the image on corrupt memory. The help file says: "On Corrupt Memory – this causes a load whenever there is no project in the controller and you turn on or cycle power on the chassis." However when I clear the program and restart it, it does not load the image. when I tried to go online it says that I can't go online because there is no project in the controller. If I change the load image to "on power up" it works flawlessly. We don't want to use this option as data is lost each time the power is cycled. User initiated is also not an option we could live with.

Any object other than ActiveX Control.

I've seen something similar. I elect to not use ActiveX controls for this reason. My first "gotcha" was several years ago with RSView32. I developed a program at work on my computer and it worked great. When I got to the customer's computer... no ActiveX, no reason why, no indication of where to look. The ActiveX I used was on my system buried in the Windows database files that the customer's computer didn't have. Once I found out what it was (horror show), I found that the only ways to get it to run on the customer's computer was to buy a full blown Windows Office to get the ActiveX, or take the ActiveX control outout. Since then I can not get myself to use them. I don't want to base the runability on a unrelated program that I cannot control.

I have many objects in Factory Talk View that I can cut and paste and the location on the screen is retained as per the original. In other objects (or groups) they are not retained. Can anyone lead me to the parameters that are keeping the object location from being retained? Objects or groups that do not retain location are always pasted in the upper left corner of the screen. I found now that if I move the original group 1 pixel, I can cut it and it will paste back to the correct location instead of the upper left corner. None of the properties change. So Weird.

I think you can share a networked 3-1/2 inch drive also.

Reset them with a first scan in the PLC.

Dial out with the Compact Logix on a modem.

You should use the /tt bit of the timer. It sounds like you may be adding 5 to the timer on each scan of the rungs where the integer is greater than 0. If that is the case you need a flg bit so that each of the "add 5" rungs is only performed once.

Cool ... But I think you have to add 1 to it.

You can also apply visibility animation to buttons (and such) using the visibility expression like this: CurrentUserHasCode( A) OR CurrentUserHasCode( B)

It sounds like you want to create an EVENT. Those are one of the logic selections the "expression" is what triggers the event and the "action" would be a set command. (writes a value to a tag) I think this can also be a string. Even if you have to create a "derived tag" to concatenate the string you will have to trigger the running of the derived file with an "event"... I think.

as far as the "voltage only" inputs: we commonly use these with a 499ohn precision resistor across the inputs. This causes the current transmitter to develop the proper voltage for a voltage input. 20 ma across 500ohms is 10 volts. 4 ma is 2 volts.

I just found one and right clicked it. I did a "save link as" then in the save window I changed the file type from "Microsoft Word document" to "all files", then changed the file extension from ".doc" to ".pdf". Once the file was downloaded I changed it back to a ".doc". I don't know if this will work for you or if it will still recognize the file as a Word document.

Yeah the Current threw me off at first too. but a lower high end makes sense in that case because the spec'ed current range is 0-21 ma.

0-10.5 volts is correct by the specification. I don't understand the counts difference though. That seems very odd. Have you checked the configuration word? I suppose nothing in your program is limiting it... Are the over range flag bits coming on?

Did you look at BNOT?

We sell Air compressor control systems. Case Controls

I don't think you need memory tags to do this... just a numeric display with a really complex expression. Something like (hh*60+mm+(ss/60))/ (HH2*60+mm2+(ss2/60) where hh is downtime hours and mm is downtime minutes and ss is downtime seconds and hh2 is runtime hours... etc etc The display would just be % downtime... not memory tag is needed.

Seems like an odd request. I think you would have to add it to a macro maybe but that sort of thing is much better done in the processor. What type of object are you trying to do this with? you can display the sum of two numbers without a memory tag. Is that what you are wanting?

I was not the keyswitch... I think we were checking to see if the program was gone by turning it back on and then putting the card in and recycling the power. It also appears that a fresh out of the box processor will load the firmware then requires another fresh memory clearing before it will load the program. Still testing.

Did that. My manager did it to and we just did it again. It does not work. I got it to work... Had to also have the key in remote mode. Thank you again, Ken. You're handier than pockets on a shirt!

I have a PanelView plus 400 with a screen that allows changes to be made to a timer preset in a Micrologix 1100 with a numeric input cursor point. On the connections tab of the numeric input cursor point properties I only have "value" pointing to the tag. When I run the application and change this value it does not always update on the screen to the new value even though the value is changing in the processor. Sometimes it works fine, other times it will not update.

The application manager in RSView Studio is a real pain in that you can only deal with on application at a time. Is there any way to do a batch application deletion?

The recipe functions in the PanelView+ is working well, but I have a few wish lists. 1) It would be nice if I could Attach the buttons to tags in the processor so I could trigger the functions with the processor instead of just the PanelView. 2) I would like to have a recipe file viewer or conversion program so I could view the file on my computer.

I had this happen to me when I put a new program in a processor that had the output on when It had been stopped and the new program did not address the output. You need to add the output to your program and just make sure it is off. I got an access denied when I tried to open the file.
