You have something going on with the hardware with input addresses 2005 and 2006. You will have to look in your hardware configuration to see what is using those addresses.
I'm not familiar with how the hardware is layed out on those things, but if you can open the project, open the hardware configuration, and then go online, you will probably see some red x's on one or more of the components (those using addresses 2005 and 2006), You may even be able to get some information about what's going on if you can open the properties of any module with a red x.) It may not be real informative, something like communication fault, ...., it may not point you to the exact problem.
The reason that the PLC is going to stop mode is because it sees a problem with those two modules. When it sees the problems it requests block OB82 (a diagnostic block) to run. If that block is not present in the project, the PLC will put itself into stop mode.
An empty OB82 can be placed into the project, downloaded, and the processor will not stop on those errors; however, that is not the thing to do with real problems. OB82 can also be programmed to extract some information about what the potential problem is, but sorry, i have no real examples of that.
Figure out what hardware is using those addresses, check the cabling between the processor and that hardware. I wouldn't play with an empty OB82 on a crane, but if you do some searching you will find how to use it properly.
