Part III FP Instructions
F152_RMRD
Data read from the slave station
s1 stores the control data for the configuration of the Master and Slave units in the network. n
words are read beginning from the shared memory address number in the intelligent unit specified
by s2. The result is stored in d.
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.
