Panasonic FPX-C14R PLC teardown
* 2mm x 40mm Phillips screwdriver.
* 1.5mm flat screwdriver.
* Medium plastic screwdriver.
* Case opening plastic tool.
Remove 2 screws from the bottom with the Phillips screwdriver. Next, remove 4 plastic latches that keep together the upper and lower enclosure parts, there are 2 latches on each side. When possible use plastic screwdrivers to keep the enclosure as intact as possible, if there are no such tools available, improvise with the thinnest flat screwdrivers and work with silk hands! .

Now with the latches unlocked , proceed to remove the upper part, the CPU board is there. In the lower part remains I/O and Power Source boards.
I/O board can be released, pulling it from the screw terminals. To releas power source board, all 4 screws must be removed. They are located at the bottom four corners.
Finally to release CPU board from the upper case, Make a lever with a thin flat screwdriver and push with the plastic tool. Repeat this process with the remaining three latches.
Useful tip, leave a very thin screwdriver inserted in the opened latch to prevent lock again when opening the second latch.
