horatio Posts: 6 Rating: (0)	there is a S7 400 station which i have connected to a laptop via an MPI to USB adapter and it gives errors when i go online and open blocks for the various modules. the specific error output is: "LAD/STL/FBD (30:504) There are no parameter and local variable names available because there is a time-stamp conflict between block interface of the blocks and the description of the parameter and variable name." this message is immediately followed by the next one "LAD/STL/FBD (30:12) The online opened block and the associated block in the offline data management are different." it takes a couple minutes for both of these errors to come up and the adapter is blinking the whole time. i assume i have to sync the offline info with the online stuff but can't see how to do it. when doing any operations that involve the blocks, there is substantial latency, not unlike when you don't have your DNS servers configured correctly on a machine that is connected to the internet. i expect that this stems from the above errors and that waiting several minutes for the programming device to complete its communication with the PLC is unusual. any advice appreciated. do not cluestick me TOO harshly :)

It has a Error table with the possible solutions. In specital for Online problems with erro code 30:504 ther's the entry: " In this case the customer can check whether the MPI LED lights on the CP5611 during this time. - If the LED does not light, the module could be defective or there is an address conflict on the PCI bus (though unlikely). - If the LED lights, then there is an interrupt conflict. - NT Diagnostics ->Resources. - Warning: with some modules you have to switch the computer off/on after BIOS changes. A possible remedy could also be to plug the CP5611 into a different PCI slot. "

horatio Posts: 6 Rating: (0)	denilson and wizard, thanks for the advice, it has been helpful. the error code dictates that offline and online blocks are out of sync, which is apparent once i compare offline and online blocks. i did a block comparison and it shows a substantial amount of differences between the offline and online blocks. some of the offline blocks are listed as being newer than those online (OB80-87, OB100-122), a few of the online blocks are newer than the offline ones (OB1, OB30) and pretty much all the rest of them are listed as being present online but not present offline. there are differences in practically every block. the offline blocks that are listed as either newer or older are likely the result of the "default" (default meaning they were there before i ever took the PG/PC online) blocks that were listed for the module. should i delete these "default" blocks while offline, then go online again and see what happens? from my experiences thus far, i expect that i need to copy the existing block data from the PLCs to the laptop so that the block "repository" is synchronized between the offline and online versions. is there a command to do this? i have been very careful about "downloading" anything since i started working with the PLCs since "download" in the context of PLCs means "download TO the PLC", not "download FROM the PLC". oh, and the machinery this is attached to is running, meaning that if i botch a "download" it would be my ass at work ;).

Hope this helps. Best regards, Wizard
