NOTE 1: For CPU program changeover, the system is reset automatically. Therefore,
when executing the program download to multiple units, set the time for the sys-
tem to execute the program changeover for the Main Unit (Unit01) after the pro-
gram download to all units is completed.
NOTE 2: If a specified changeover time is passed while CPU program is being download-
ed, the changeover of CPU program is executed immediately (second data be-
comes 000000000000).
NOTE 3: If you set the second data to 000000000000 while CPU program is being down-
loaded, the CPU program changeover is executed after CPU program download
is completed.
NOTE 4: This data is cleared after CPU program changeover is completed.
NOTE 5: If the system is reset five times during about three minutes, the CPU program
changeback is executed automatically.
NOTE 6: When the communication between Main Unit-Remote Unit/Primary Unit-
Secondary Unit cannot operate normally, “HARDWARE ERROR” is displayed.
