The
includes the following parameters. The graphs show the memory total with either green, yellow or red indicating if enough memory is remaining for processor background tasks that require additional memory to operate properly.

TIP:
When online with the controller, the settings show the actual memory used by the controller. The
Max Used
setting shows the peak memory usage as communication occurs.Parameter | Description |
Memory Option | Specifies the controller to use in the estimate. This is available only for controllers with different memory size options. |
Estimated I/O Memory | Displays the total memory bytes available, the number of unused bytes, and the number of used bytes for storing I/O. Also displays the largest free contiguous block of memory. |
Estimated Safety Memory | Displays the total memory bytes available, the number of unused bytes, and the number of used bytes for storing Safety components. Also displays the largest free contiguous block of memory. This is available only for Safety controllers. |
Estimated Data and Logic Memory | Displays the total memory bytes available, the number of unused bytes, and the number of used bytes for storing data and logic. Also displays the largest free contiguous block of memory. |
Reset All Max | Resets the Max Used values. |
Estimate | Re-estimates the amount of controller memory required for the project. |
Ethernet Nodes | Shows information about the Ethernet nodes connected to the controller.
If the controller is offline,  appears next to the Used parameter when the node count exceeds the limit. |
