Configure Control System Memory

One of the most difficult decisions to make when you plan for a new system is the manner in which the memory of a control system is configured. All control systems contain a specific amount of memory. In many of these control systems, you can configure the memory. Use the following general guidelines to help allocate the available memory into specific portions that minimize memory problems associated with system installation and expansion.

The following memory concepts are similar for all control systems:

• Most control systems have different types of memory that correspond to different aspects of the overall program.

• The most sophisticated control systems allow you to configure the memory.

• Each control system has a finite amount of available analog and discrete memory.

• A control system is capable of supporting only a limited number of inputs and outputs.
