Part III  FP Instructions 
F151_WRT 
Write into memory of intelligent units 
 
 
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. 
Writes n words of the initial data from the area specified by s2 of the CPU to the address specified 
by d of the shared memory of the intelligent unit specified by s1. 
The number of variable arguments at the inputs is limited by the available index registers of the 
PLC.
