Vision controllers contain two types of memory:
RAM (Random Access Memory)
The controller uses RAM memory to run the application, make
calculations, and manipulate data.
RAM memory is volatile. This means that it requires power in order to
maintain stored data.
Data stored in RAM:
The application, operand values, variable values, and Data Table sections
that are not marked Part of Project.
This data, as well as the RTC, is backed up by the battery.
FLASH (Flash Erasable Programmable Read-Only Memory)
The controller uses FLASH memory for data storage. and to store backup
applications.
FLASH memory is 'non-volatile'. It does not require power in order to
maintain stored data.
Data stored in FLASH:
Data Table sections that are marked Part of Project and Back-up
applications, including applications that can be uploaded.
Backing up your application
In order to make sure that your PLC can recover its application in
the even of total power loss--including battery failure--you must
back up your complete application in the FLASH memory. To do
this, use one of the following options from the
Connection>Download menu, which differ according to the Vision
Division you controller belongs to:
