3.7 List of Remote Buffer Memory Areas
Do not access any system area using the REMFR or REMTO instruction. Doing so may cause malfunction.
3.7.1 Main A/D converter 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 parameters in the parameter area are backed up to the non-volatile memory.
The parameters backed up to the non-volatile memory are read out to the parameter area when the module
power supply is turned off and on or the module is reset by 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. For the parameters written using the
REMTO instruction, the timing of the write to the non-volatile memory is at the time of turning on Initial data
setting request flag (RY9) from off. At this time, even an invalid parameter is written to the non-volatile memory as
well. With an invalid parameter written, turning off and on the power supply causes the invalid parameter to be
read from the non-volatile memory, resulting in the error code being stored into Latest error code (RWr0). Take
corrective action with reference to the error code list. ( Page 172, Section 11.2)
