What is the Maximum number of variables that the Magelis line of HMIs will handle?

Number of variables per panel (limit)
iPC Series: Maximum 2500 variables per panel
All other target types: Maximum 800 variables per panel.

Number of variables per target (limit)
iPC / XBTGTW Series: 12000 max.
XBTGC / XBTGT / XBTGH / HMIGTO / HMISTO / HMISTU Series: 8000 max.
XBTGK Series: 8000 max.

NOTE: For iPCs, if persistent variables such as alarm variables and data logging variables are used, a maximum of 8000 variables can be supported for each iPC target.

Number of variables you can share (recommended)
iPC / XBTGTW Series: 400
XBTGC / XBTGT / XBTGH / HMIGTO / HMISTO / HMISTU Series: 300
XBTGK Series: 300

NOTE: The Maximum Number of Shared Variables is the recommended maximum number of variables that is shared at any one time NOT the maximum number of Sharing-enabled (Read-only or Read/Write) variables. In other words, the number of variables that you set to Read-Only or Read/Write has no limits; only the number of variables that are accessed by other targets is limited. Performance may become an issue if you exceed the recommended maximum.
