Determine task count dynamically for taskinfo.db

[ZLLentz]

I suspect most of our PLCs have either 1 task or 2 (fast task and slow task)

[ZLLentz]

Do we read it from the tmc/project? Or is there some ADS interface for getting the number of tasks?

I took a brief look into the TMC file and didn't see anything regarding tasks; but I assume it's because it's a fairly dynamic thing?

[ZLLentz]

I think the number of tasks is predefined in the project, so the information should be in there somewhere, if not in the tmc then in one of the other xml files

Hmm, you're right - this is also useful information for the summary pages:

In [9]: list(project.find(Tasks))
Out[9]: [<Tasks children=[<Task name='PlcTask' attributes={'Id': '5', 'Priority': '20', 'CycleTime': '100000', 'AmsPort': '350', 'AdtTasks': 'true'} children=[<Name text='PlcTask'>]>]>]

However, for lcls-plc-kfe-motion I'd have expected to find more than just one (right?)

[ZLLentz]

Probably only one PLC task, but there should be a few NC tasks. I think that DB file only looks at PLC tasks.

I think I should tackle this as part of #86 - need to look into this again
