Memory Requirements

iClients and SCADA nodes (without Enhanced Failover or GE Historian) require at least 2 GB RAM. For better performance, please consider using more.

NOTE: As more applications run simultaneously on a SCADA server, performance decreases. Whenever possible, run additional applications on different computers.

If your picture cache size increases, your memory requirements should increase:

• 2 to 3 times the file size for each picture that does not include bitmaps and controls.
• 3 to 4 times the file size for each picture that includes bitmaps and controls.

For example, a 2 megabyte file that does not include bitmaps and controls requires a 4 to 6 megabyte increase in memory. A 2 megabyte file that includes bitmaps and controls requires an increase in the memory of 6 to 8 megabytes.
