RegisterBank

This instruction reads the number of words specified by DataNumberOfWords from File Register

Bank 1 or 2, as specified by BankNumber beginning with BankOffset, and writes it to

DataStartAddress.

With this function you cannot read data in the FL area (File Register Bank 0), i.e., the variable

applied at DataStartAddress must not be located in the FL area.

To add an enable input and enable output to the instruction, select [With EN/ENO] from the

"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the

context menu or press <Ctrl>+<Shift>+<v> in the programming window.
