Memory and Performance Characteristics
Introduction
Processor Adapters are equipped with internal memory and Flash RAM. This
section explains those two types of memory and describes the memory size and
performance characteristics of each Processor Adapter.
Internal Memory
Internal memory includes user memory and state RAM:
User memory contains the control logic program and such system overhead as
the Processor Adapter configuration, I/O mapping, checksum and system
diagnostics.
State RAM is the area in memory where all the input and output references for
program and control operations are defined and returned.
The user may change the way internal memory is allocated by adjusting
parameters for user memory and state RAM.
Flash RAM
Flash RAM contains the executive firmware, which is the operating system for the
PLC. It also contains a firmware kernel, which cannot be changed. The kernel is a
small portion of memory that recognizes acceptable executive firmware packages
and allows them to be downloaded to the Processor Adapter.
Space is also provided in Flash so that a copy of the user program and state RAM
values can be stored. This back-up capability is particularly useful in configurations
where no battery is used (ie., a Processor Adapter without an Option Adapter).
