1.2 Introduction of product
The handy programming panel FX-20P-E is a hand-held programming and monitoring panel
used to write programs (sequence programs and parameters) to MELSEC-FX Series
programmable controllers (hereafter referred to as PLC). It can also monitor their operation of
a sequence controlled application.
1.3 Features
• FX-20P-E is a programming/monitoring unit of the compact hand-held type.
• The liquid crystal display unit of 16 characters ×4 lines displays the program, PLC operation
status (monitoring), operation guidance and error messages.
• The FX-20P-E is equipped with online mode and offline mode functionality. In the online
mode, the FX-20P-E directly accesses the memory with the connected PLC.
In the offline mode, the FX-20P-E accesses the RAM built in itself. In addition, because the
FX-20P-E is equipped with the inbuilt large capacitor, it can back up programs written in the
offline mode. (With power supply for 1 hour, the FX-20P-E can back up programs for a
maximum of 3 days.)
• The FX-20P-E reads writes programs and executes a monitor display in list format.
• When an optional product is combined, the FX-20P-E can work as a ROM writer for
memory cassettes available only with the FX Series PLC.
Programs cannot be written or changed while the PLC is in the RUN status.
