Station number settings
When SD latch setting is set to "no latch", a station number of a local station that is set in the engineering tool and used in MC

When SD latch setting is set to "latch", the contents of station number settings can be changed by program or engineering
tool, and by turning power supply ONOFF or by system reset, it can be operated with the station number stored in the
