Regarding Tag Placement.

[LV_COder]

Hello All,

I have a doubt about the below tags.

EH2. Sensor Interface IO Error. The Controller executes a Termination Process.

EH3. Process Step Error. The Controller executes a Termination Process.

CD2. The Controller reads and updates the Configuration Database.

In the sample exam the above tags are being placed in the error module and in the database module.

But as per reading of the instruction, it seem these tags will be placed in the controller in the terminate state

and for Database tag, it will be in the controller where reading and writing to the database happens.

Can any body please help me in understanding of the above??

thanks in advance.

Hi Hemant, 

For a tag to recieve credit it must be placed in a relevant location. This changes based on what the tag covers. However a good guideline is to place a tag and point it to a specific item (subVI, structure, node, function, comment, etc.) that is used to cover the requirement. Placing tags in a large clump anywhere inside a VI without any supporting material will recieve a low score. 

The idea behind tags is to use them to show that the requirement has been covered by the object it is pointed to, and not as an instruction to the developers completeing the project. (a common problem I've seen in CLA exams)

Please remember that the sample exams did not recieve perfect scores. You should use them as a guideline, but focus on how they could be improved.

Thanks Nath for your information. 

Can you please share some thought about the requirements tag that I have mentioned above regarding error handler and database.

These  tags should go to controller module or the way the sample exam has tagged is correct only.

Hello Nathanael,

1. I have understood that tags should must be placed to specific location where the requirement has been satisfied.

2. Sample exam are not fully proper and should be used as a reference.

3. Requirement : Sensor Interface IO Error. The Controller executes a Termination Process.

In the above requirement like in 3 point. As per my understanding this requirement should go to the controller module where the controller is executing the termintaion state rather then in error module.

Can you please share whether my understanding is correct or this requirement ID should go to error module..

Its bit confusing me as i have seen the all sample exam and in all the sample exam this above requirement ID is being placed in error module.

Can you just help me to under stand where this requirement ID will be going to placed to meet the requirement correctly..

Thanks In Advance.

Hi Hemant, 

I can't give out direct answer to exam questions. 

That being said, for this example, think about the message path and order of operations that must occur in the event of a critical error.
