Confirming Changed Timer/Counter Preset Values
This section describes the procedure for writing changed timer/counter preset values from the MicroSmart CPU module
RAM to the EEPROM. This operation writes the changed preset values of both timers and counters at once.
The changed timer/counter preset values are stored in the MicroSmart CPU module RAM and backed up for 30 days by a
lithium backup battery. If required, the changed preset values can be written to the MicroSmart CPU module EEPROM as
described below. For the data movement in the CPU module, see page 7-13.
1. Select the Timer/Counter Changed Preset Value Confirm menu.
2. Confirm the changed timer/counter preset values, and write the changes from the RAM to the EEPROM.
