For the REMFR and REMTO instructions, refer to the following.

For the access method, refer to the following.
• Parameter area ( Page 84, Section 7.1)
• Error history area ( Page 221, Section 11.1)
Do not access the system area using the REMFR or REMTO instruction. Doing so may cause the module to malfunction.
(1) Parameter area (address: 0000
For the parameter area, parameters can be set using the CC IE Field configuration of the engineering tool or
using the REMTO instruction.
The parameter in the parameter area is backed up to the nonvolatile memory.
The parameter backed up to the nonvolatile memory is read to the parameter area when the module power
supply is turned off then on or the module returns from remote reset.
If the parameter is written from the parameter setting of the CC IE Field configuration of the engineering tool, it is
also written to the nonvolatile memory at that time. When the parameter is written using the REMTO instruction, it
is written to the nonvolatile memory when Initial data setting request flag (RY9) is turned off then on. At this time,
the parameter is written to the nonvolatile memory even though it is incorrect. When the power supply is turned
off then on with an incorrect parameter written, the incorrect parameter is read from the nonvolatile memory and
an error code is stored to CH Latest error code (RWr22, RWr3A). Take corrective action according to the error
code list. (Page 225, Section 11.2)
