If Upgrading Firmware
The user program, configuration, CPU ID (used for SNP communication), and status tables will automatically
be cleared when the CPU firmware EPROM is changed. So you will need to restore these after performing a
firmware upgrade. The user program, configuration, and status tables can be restored from a program folder,
from memory card, or EEPROM. The SNP ID must be set separately using the MS-DOS PLC programming
software, VersaPro software, or the Hand-Held Programmer.
