Load not possible at present
while downloading am getting attached error. Different version detected. i had installed both emulator and control builder F on same PC. version is 8.2.
Please find the attached error.
This is normal.
If you are sure the project you have open is right, you need to select whole station,
If you are not sure, look for another version of your project, and check again.
The last staement is correct. By Version error on a station (here, a process station) , you must suppress this status by load the station with "load whole station". Otherwise you cannot commission this station.
Please notice that during the sequence "load whole station" , the station will be shortly stopped.
Background of the Version Control is to detect differences between the application in the project database that Freelance Engineering (CBF) uses and the application in the target resources. This way it is possible to detect that you use the wrong project file, or someone has modified the application in the target resource (maybe with a copy of your project file on a different PC, which means you do not have the latest version).
In order to get a little more information about the version error one can call up the Load / Version Informations dialog from the Freelance Engineering in commissioning mode after selecting a resource in the P-tree.
For the selected resource it will show the information that Freelance Engineering has about commissioning of that resource and the information the target machine has. The numbers presented there should be equal. If they differ at least in one aspect a version error is the result.
With a version error the CBF will no longer allow for a Load / Changed Objects to that resource in order to avoid inconsistencies which mixing different application versions would create and which could lead to crashes in the target resources.
If you are in an emergency situation and need to do some immediate changes in order to avoid damage to equipment or the product, CBF provides the Load / Ignore Version Error menu. For the next load the differing versions are ignored and you can load your changed object. Afterwards the version error will reappear.
This option should be used with great care, because you might worsen the situation if you are not aware what part of the application differs.
In order to overcome the conflict situation one has either to find the correct project file (where the numbers match) or use the Load / Whole Station comand. The latter clears the application in the resource and then loads the complete application, thereby making the numbers equal.
There are some situations, where the number for downloads or corrections differ only by one, and you know exactly what the differences are. Examples for such situations are
a) You by accident deleted the current project, but you have a backup done before your last change.
b) Your CBF is connected via the internet (and a VPN) to a remote controller. You do a correction, but after the controller received the instruction the Internet connection breaks down. You are left with the controller and CBF having the same application, but CBF thinking the last correction failed, which results in different Correction numbers.
For those special situations you can use Load / Adjust version error and then make sure to download the last changes again.
After using "Ignore Version Error" or "Adjust Version Error" it is good engineering practice to do a "Load / Whole Station" at the next possible opportunity.
