Main I/O module

(1) 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: 0110H to 011FH, 0130H to 013FH, 0210H to 021FH) 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 238, Section 12.2)
