FATEK M Series User Manual page 25

When being installed in different types of expansion modules, the Expansion Module Configuration
of the M-Series PLC will display different types of configuration pages, as indicated below.
The Expansion Module Configuration of the M-Series PLC is saved in the expansion module directly. Even
if the CPU module is damaged, such expansion module can still operate independently to show the
corresponding processing action. In this way, it not only improves the system stability but also intensifies
the system security.
The expansion module configuration of M-Series PLC is saved in the project and the expansion
module instead of being saved in the CPU module. Before replacing the expansion module, you need to
set the expansion module configuration in the expansion module or save the project on the SD Card and
then the CPU module will write the expansion module configuration being saved to the corresponding
expansion module.
