AC800M Processor Memory details

Hi,

Can anyone tell me how much percentage of total memory suppose PM861AK02 has 16MB processor out of which how much is available for Logic development only.

How much load/memoryoccupied by a PID block in logic building?

Can i run three loops in a same scan cycle in different time? How to do it?

Thanks in advance

Hi,

I can suggest to look in Control Builder, Product Guide, for example 3BSE041586-510.

It depends on version, system e.t.c. - have to look for the version, that you have.

As I know for Compact Projects, PM861A has something about half of total RAM memory, available for application (e.g. 7.8 - 8 MB), the other part is ocupied from firmware (and that is not a small amount of memory)

For PID load - it depends on the type of it - look in the manual. For example PIDLoop consumes 55.8 kb for the first obect, but only 6.2 kb for the next obect from the same type !

Third question is not clear? Yes, you can run 3 loops ! But the cycle and task are different things. Cycle time is defined for each task.

All programs, connected to the same task, has the same execution time.

If you need different execution times (cycle) for the 3 loops, you have to put them in different programs and connected each program to different tasks
