Hi, after watching a lot of content from Realpars I still have some doubts I'd like to resolve:

what would it be the use case scenario of configuring the Analog modules to store their values in the PII/PIQ memory like digital input/output cards do for every end/start of a scan cycle?

Is it possible to have an unsigned integer as a data type?

An whats the difference between tags assigned as Global Input and Global memory, like M10.1 for instance. In practice I see no difference.

Thanks

If access is made to the inputs and outputs via the operands "I" or "Q" in the user program, then there is no direct access to the input/output modules. In this case, access is made to a memory area in the CPU's system memory. This area is called the process image of the inputs (PII) and the process image of the outputs (PIQ). The contents of the process image (PII and PIQ) do not reflect the actual values of the inputs/outputs, but the values at the time the process image was updated. If more recent values are required for individual processes, you also have the option of direct peripheral addressing. You would only want to grab the live value from the PIW table in cases where the PLC scan time is long or the value is changing very rapidly and some action has to be taken before the next scan.

WORD and DWORD are both unsigned integer types.

Global Input is used to described a Global Memory item that is being used as an input to a Function or Function Block and is not a different type of memory.
