A2.6 Backup Function
The F3CU04-0S or F3CU04-1S temperature control and PID module provides a backup
function for storing input type, input range, set points and other parameter values, and
hence retaining their values even after power off and on. Parameters designated for
backup are stored whenever their corresponding registers are updated, provided the
backup function is not disabled. However, you need to execute a specific procedure
every time to back up set point values. Otherwise, stored set points will not be updated.
Even so, beware that set points will not be updated if the backup function is disabled.
Take note that there is a maximum limit to the number of write operations allowed for the
backup function.
Table A2.6 Backup Function
Description
Stored parameters
Controller parameters, I/O parameters, and operation parameters. For details, refer
to the list of registers.
Number of write
operations
Up to 100,000 write operations allowed
Disable backup function
This parameter disables the backup function. It may be used, if required, to avoid
reaching the maximum limit for write operations.
For details on the I/O data registers that are stored by the backup function and their data
position numbers, see Section B2, "Types of Relays and Registers."
In situations where the CPU module frequently overwrites the I/O data registers
earmarked to be stored by the backup function, the maximum limit for write operations
(100,000 times) may be reached. To prevent this, turn on the Disable Backup Function
parameter. Once the write limit is reached, data backup is no longer allowed and the
system enters hardware failure mode. Furthermore, parameter data may be reset at
system startup to the default values given in Section B2, "Types of Relays and
Registers."
