Frequently Asked Questions (FAQ)

Q: What is the difference between the -SBD and -SBD-M3 variants?

• A: The -M3 suffix typically indicates a model with enhanced memory capacity, allowing for more complex screens or larger projects compared to the standard version.

Q: Can this GOT connect to newer Mitsubishi PLCs like the iQ-R or iQ-F series?

• A: No. The A951GOT is designed for the older A, QnA, and Motion controller families. Connection to newer series usually requires different interface modules or newer GOT models.

Q: Is the display touch screen?

• A: No. The A951GOT-SBD model uses button keys (located around the screen) for operator input. It is not a touch-screen unit.
