• Do not access the system area using the REMFR or REMTO instruction. Doing so may lead the module to
malfunction.
• Do not use the dedicated instruction of the REMFR and REMTO instructions to the areas later than the
above areas. If these instructions are used, the error code (0202H) is stored in Warning code (RWr2),
Warning status flag (RWr0.b12) turns on, and the ERR. LED flashes.
Parameter area (address: 0000H to 04FFH)
For the parameter area, parameters can be set by means of the CC IE Field configuration of the engineering tool, or the
REMTO instruction.
The parameter in the parameter area is backed up to the nonvolatile memory.
However, Fast logic setting Y (address: 0120H to 0127H) is not backed up. The parameter backed up to the nonvolatile
memory is read to the parameter area when the module power supply is turned off and on or the module returns from remote
reset.
For the parameters written from the parameter settings of the CC IE Field configuration of the engineering tool, the write to the
non-volatile memory is also completed at the same time. When the parameter is written using the REMTO instruction, it is
written to the nonvolatile memory when Operation condition setting request flag (RWw0.b9) is turned on. At this time, the
parameter is written to the nonvolatile memory even though it is incorrect. When the power supply is turned off and on with an
incorrect parameter written, the incorrect parameter is read from the nonvolatile memory and an error code is stored to Error
code (RWr1). Take corrective action according to the error code list. (Page 124 Error Code List)
