Because the keep relay is battery–powered memory, switching off the
power will not erase the data in it.
Each PMC–NB6 area is as listed below:
Area available to the user K0 to K39
Area used by management software (Note) K900 to K909
WARNING
Area used by PMC management software
Because this keep relay is used by the PMC management
software, it cannot be used by the sequence program. Any
area left unused should be reset to 0.
See (4) in Section 6.1, Chapter 6, Part 1 for details.
