Frequently Asked Questions
Which connection boxes can be used with 6AV6645-0CA01-0AX0?
Compact, standard and advanced second-generation connection boxes are supported with the documented predecessor-device restrictions.
Does 6AV6645-0CA01-0AX0 support PROFIsafe through those connection boxes?
No. The predecessor-device arrangement supports a hardwired safety system, not PROFIsafe communication.
What display must a replacement for 6AV6645-0CA01-0AX0 match?
Match the 7.5-inch active TFT area, 640 x 480 resolution and 64k-color display.
How is 6AV6645-0CA01-0AX0 operated on the machine?
Operation is through an analog resistive touchscreen and an 18-key membrane keyboard with LEDs.
What enabling circuit is built into 6AV6645-0CA01-0AX0?
A two-circuit, three-level enabling switch rated for 24 V DC is integrated.
What project checks are needed before installing 6AV6645-0CA01-0AX0?
Confirm the archived HMI project, engineering-software compatibility and the connection-box wiring.
How should engineers verify a 6AV6645-0CA01-0AX0 replacement variant?
Compare the full article number and the fitted safety controls; related Mobile Panel 277 variants have different control elements.
