Overview of Momentum M1 Processor Adapters

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	Internal memory includes user memory and state RAM:
	λ User memory contains the control logic program and such system overhead as
	the Processor Adapter configuration, I/O mapping, checksum and system
	diagnostics.
	λ 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	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 (i.e., a Processor Adapter without an Option Adapter).
	When the module is successfully communicating with other devices, if a ring
	adapter with battery back up is not present, it is recommended that you stop the
	processor and save the user program to Flash. This will save the processor’s ARP
	cache and enable it to “remember” this information if power is lost or removed.
	This procedure should also be followed whenever:
	λ A new or substitute device is installed on the network;
	λ The IP address of a network device has been changed.
	Note: Some processors run both IEC and Ladder Logic and some run only IEC.
	See table following.
