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.
