The "Confirm" button is on the right-hand side on the front of the safety modules, above the
USB interface. Briefly press this button using a pen to confirm a new configuration loaded via
the USB interface. It is then accepted by the safety module.
Resetting errors
Use the "Confirm" button to reset displayed errors. Depending on the error type, the "Confirm"
button must be pressed briefly (3 s) or for a prolonged period of time (min. 15 s).
Restart
To initiate a restart of the device, press the "Confirm" button on the device for at least 15 sec-
onds. As part of the warm start process, all outputs are initially set to the safe state. Pending

USB interface
Communication between the safety module and the MSIsafesoft configuration software takes
place via the USB interface (standard USB 2.0). The communication includes the following
events:
–
Downloading of the configuration data (i.e., for the MSIsafesoft project)
–
Optional: uploading of the configuration to open it as a project in MSIsafesoft and edit it
as required
–
Reading of values from the safety module during operation and "live" display in the con-
nection editor of MSIsafesoft (online mode)
–
Forcing of signals on the running safety module for commissioning purposes (non-safe
commissioning mode)
See also "Downloading configuration from the MSIsafesoft configuration software" on
page 80.
For the precise procedure, please refer to Chapter "Loading the configuration using the
AC-MSI-CFG1 memory module" on page 84.

safety module is in non-safe operation. The safety function cannot be properly executed.
•
Only use the USB connection for commissioning.
•
Disconnect the USB connection for regular operation.
ATTENTION: Electrostatic discharge
The safety modules contain components that can be damaged or destroyed by electrostatic
discharge. When handling the USB interface, observe the necessary safety measures
against electrostatic discharge (ESD) according to EN 61340-5-1 and EN 61340-5-1.
