User range
After the data is written, the range is switched when the programmable controller power supply is turned off and on or when
the CPU module is reset.
With the following buffer memory areas, the range switching and range setting can be monitored.
'CH1 Range setting' (Un\G598)
'CH1 Range setting monitor' (Un\G430)
For details on the buffer memory addresses, refer to the following.
