Reset Button
The XCL8010 Controller Module is equipped with a reset
button.
Fig. 50 Reset button (1)
Pushing the reset button (1) using, e.g., a paperclip will
cause the XCL8010 Controller Module to reset.
NOTE: In the event of a reset, all non-volatile memory
contents are permanently deleted, though the
clock will not be set to zero. In order to avoid
problems, we therefore recommend that you
always save your application changes (e.g., time
program changes) to FLASH memory.

HMI Interface
The controller module is equipped with an HMI Interface for
the connection of HMIs, e.g., the XI582 or the XI882A, or a
laptop (with XL-Online/CARE).
