Parameters
(g) Checking whether boot is normally completed
Whether a boot is normally completed or not can be checked by the following.
• The BOOT LED turns on.
• The special relay (SM660) turns ON.
• Choose [Online] [Verify with PLC] on GX Developer and verify the data
written to the transfer source memory and the data in the program memory.
(3) Operation for stopping boot run
To stop boot run and execute operation using the parameters and program files
written to the program memory, perform the following operation by GX Developer.
1) Write the parameters, which are not set as a boot file, to the program memory.
2) Set the parameter-valid drive DIP switches of the CPU module to the "program
memory". (SW2: OFF, SW3: OFF)
3) Power on the PLC again or reset the CPU module.
