Data transfer within the PLC
F150_READ
Reads data from the shared memory in an intelligent module.
Description
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.
The n words of the data stored in the shared memory of the intelligent unit/board specified by s1
are read from the address specified by s2, and are stored in the area specified by d of the CPU.
The number of variable arguments at the inputs is limited by the available index registers of the
PLC.
