GT series: Method for reliable screen switching by PLC

I use both the instruction from PLC (FP0) and the function switches of GT11 to switch the screens. However, the second instruction from the PLC does not work.
When both the function switch and the PLC are used for screen switching, it causes mismatch between the screen data specified by the PLC (DT0) and the currently displayed screen data (DT2), and it may become impossible to switch the screens by PLC. The following is a sample program to solve this problem. The key point is to SET and RESET the forced screen switching flag RE. Write this program just before the END instruction.
(Example) Program for switching between screens 0 and 1
For FP-MC16T, FP1C14, and C16, use instruction F60.
