Retentive Memory
These settings apply to how the retentive memory is allocated in the unit.
EventLog DataBase:
Enables user to keep EventLog information in retentive memory. When the HMI starts up, it
checks the in retentive memory and retrieves EventLog DataBase information.
DataBase Start Address:
(0~59999). Information is stored in retentive memory starting with the specified address.
Note:
LW9058-9059 contains the size in words of the EventLog in retentive memory. Keep in mind that once a
block of retentive memory has been reserved, your project cannot use it for other purposes. We recommend that
you specify the DataBase Start Address to be after stored recipes so they are not overwritten with Event Log data.
System Parameter:
Enables the user to change some System Parameter Settings in the HMI. The parameters are
stored in retentive memory beginning with RW60040.
For example: RW60041 represents the PLC port baudrate. If you change this value, the next time the HMI is
powered up, the baudrate is set to the value in RW60041.
Note:
Set LB9044 to ON to activate System Parameter changes from the Retentive Word area immediately.
Note:
Caution should always be observed when changing System Parameters. There is the possibility of making
the unit unable to function in the application. When this happens, the project must be downloaded again to restore
the System Parameters.
