2-Series Memory & Directory Structure
Introduction
A 2-Series control system has 36MB of built-in memory (non-volatile and volatile).
The following diagram illustrates the memory structure of the 2-Series Control
System.
2-Series Memory Structure
32 MB SDRAM Volatile Memory
1.5 MB of operational memory
(CUZ file)
2.5.MB of Non-Volatile Memory
(SIMPL program storage, web files,
accessible directory structure)
Expandable to 4GB using flash
card
256 kB NVRAM
The total of 36MB is specified as follows: 4MB flash (non-volatile), 32MB SDRAM
(volatile), and 256KB NVRAM (battery backed up). Flash memory contains the file
system inside the 2-series control engine. Non-volatile memory contains information
that is retained after the loss of electrical power. Volatile memory is lost after a
power failure. Refer to the lists below for a breakdown of memory usage for
program-related information stored in the unit.
