6.7.1 ROM Operation Function
The FP2SH is equipped with a function that causes programs, or programs and data,
to be stored in a ROM (FROM or EPROM) that does not require backing up. This func-
tion also causes operations to be executed based on the contents of that ROM.
Type FP2−C2L, FP2−C2 FP2−C2P, FP2−C3P
Storage memory FROM or EPROM (optional) Internal FROM
Remark Memory unit (AFP2208 or FP2−EM7)
With the memory unit (FP2−EM7), the master memory
(AFP5208) or memory (AFP2509) is required.
FROM is not detachable.

The “Download to PLC” function in the FPWIN GR can be used to write programs
and comments.
When doing this, programs are stored in the internal RAM in the FP2SH, and
comments are stored in the internal RAM if the FP2−C2 is being used, and in the
comment memory of internal FROM if the FP2−C2P or FP2−C3P is being used.

Programs and data in the internal RAM of the FP2SH are written to the user ROM
with the “RAM → ROM transfer” function in the FPWIN GR.

Programs and data in the user ROM are written to the internal RAM of the FP2SH
with the “ROM → RAM transfer” function in the FPWIN GR.

If the power supply is turned on with DIP switch SW2 set to “on” (SW4: off), pro-
grams and data stored in the user ROM are automatically sent to the internal
RAM in the FP2SH.
