Forgive, because I'm sure this question has been asked and answered.  Just can't seem to find anything on Rockwell's website, KnowledgeBase or this forum.  Any link's would be welcomed. Can someone describe the capabilities and differences between Lite and Standard?

Exactly what I needed Mr. Tim!

Are you getting any messages or dialog boxes? In the Application Manager, you should select Restore Archive. If it's still not working, then it's an uninstall and reinstall and try again.

Two quick things to check. First the IAI must be in the IO Tree.  Find and read the manual and sample programs.  Generally, its a Generic EtherNet Module. Next, obviously you have configured logis in a sub routine.  Make sure the sub routine is called (JSR) from the MainRoutine.   Lastly, my IAI distributor is execellent and if he can't help me he has three IAI engineers available in an hours and sitting next to me to help.

I think cal04 is looking for something similar to change tracking or history for the purposes of FDA reporting and validation efforts.  If that's not what is being asked, I'll remove my post.  CFR 21.11 compliance?

Couple of "unwritten rules" of ML and SLC programming. 1.  Every program should have at least one rung with an SVC or Service Interrupt.  This prevents the code, with a programming error such as an endless loop, to break the code scan and allow for communications to occur with other devices such as an HMI. 2.  The very last rung LAD2 should have an OTU of S:5/0 otherwise known as the Math Overflow Trap.  This will prevent the processor from faulting and allow you to debug your code.

How sure are you that the offline program matches the current loaded program in the ML1500?  If you think it matches, you should be able to download and then monitor until the next fault. Others have better answers regarding MicroLogix.  Some models do or do not allow online editing.  But I believe you should be able to at lease monitor the program online in the 1500.

The S: Files will tell you the fault code.  Then look at the manual for the description and possible solutions.

Did you go online with the PLC? What were the error codes?  Any diagnostics on the LabVIEW side of things?  What have you done thus far to debug the issue?

I believe the proper solution is the DIV.  Of course, that requires one to have previously MUL by the same number of digits on the other side.

It was just you Joe , j/k. I've seen the same thing for about a month or so.

From the controller properties, you can see available and used memory. From the tasks you can see scan times. If memory is low, there are a few things you can do to reduce the memory used.  A copy of every datatype, module type, udt and aoi is downloaded to the controller, even if there is nothing is using them in code.  Going offline you need to check for cross-references for every data type, module type, udt, aoi.  If they are not used in the program, you'll want to delete them and download to the controller.  I've been able to reduce memory usage by 10%.

I don't think so, it's either in the PLC with macros in the HMI or use the built in security functions of the HMI. To clarify, the user name and passwords are based upon the Microsoft security.  The HMI does have an ability to change the password, but it is a manual intervention and only applicable to the application running on the HMI (i.e. the MER).  It won't even be the same when compared tot he project within FactoryTalk View ME. So, if you want something that is random and automatic, you'll probably want to do it in the PLC.

Exactly as I answered in the previous post. https://forums.mrplc.com/index.php?/topic/38941-factorytalk-view-se/ Guess mabdulrehman961 wanted another opinion.

Looks like an Omron program.

looks like the timer preset is 50ms.  Might be happening so fast you can't see it.

Was sent a picture of a 1769-SDN with both 8-Segement LEDs showing the upper for segments lit up as a small square.  In otherwords, not a normal large square or 00.  Has anyone encountererd this before?  Looked at manuals and this LED arrangement is not described.  

Update!  Finally got someone on site.  Turns out someone added a node at address 00 which conflicted with the 1769-SDN at 00.  Told that they were seeing a 70, but no one every said that before.  Had them change the offending node to it's proper address at 52 and everything went back to normal.

When in SE project, you can configure as many Device Shortcuts as you like.  Each one talking to a different PLC. Download and read a manual or get some training from your local Rockwell distributor.

Reading this online manual, the answer is no. https://us.idec.com/idec-us/en/USD/medias/EP1624-FC6A-datasheet.pdf?context=bWFzdGVyfGRvY3VtZW50c3w5NDc5MzB8YXBwbGljYXRpb24vcGRmfGRvY3VtZW50cy9oMDQvaGFiLzg5Mjk2Njg4OTA2NTQucGRmfDI3MzRkYzg3ZGRlODA0NWZmYTdhYTdjNGZlMTEwYzNiMzAwZDNmMzc0OGNiMjdmYjJiMDExYmU5Yzc3NWY4ODM

Yes

or a PC with ME Runtime

AnyBus has one, also used SMC's (valvebanks)

We've written a routine in the PLC that adds the numerical value of the date so that the password changes every day.

And if you add :EIP to each IP in the Ethernet Devices drive, it essentially turns into the EIP driver.  More specifically, it reduces to the specific ports for TCP and UDT for Rockwell products.
