GENERAL DESCRIPTION
SAFEMASTER PRO is a configurable safety system. It consists of a control unit UG 6911.10, which can be
configured using the SAFEMASTER PRO DESIGNER graphic interface, and a number of expansion modules
connected to the control unit UG 6911.10 via the proprietary IN-RAIL-BUS.
The control unit UG 6911.10 e. g. UG 6911.12/080 can also be used as a stand-alone device. and they are
equipped with:
• UG 6911.10: 8 safety inputs, 2 independent programmable dual channel safety outputs (OSSD)
and 2 logic signal outputs
• UG 6911.12/080: 8 safety inputs, 4 independent programmable single channel safety outputs (OSSD
and 4 logic signal outputs
The following expansions are available: Input / Output module (UG 6916.10 and UG 6916.12/080 (for
UG6911.12/080only)),inputmodules (UG 6913.08, UG 6913.12 and UG 6913.16), output modules OSSD
(UG 6912.02, UG 6912.04 and UG 6912.04/100), with dual channel semiconductor outputs, output
modules relays with guided contact safety relays (UG 6914.04/000, UG 6914.04/008, UG 6912.14 and
UG6912.28),output modules with programmable signal outputs (UG 6915/008, UG 6915/016) and several

The control unit and its expansions modules communicate via the 5-way IN-RAIL-BUS (from DOLD), physically
arranged on the rear panel of each unit.
Furthermore 8 inputs and 16 outputs probe controllable (by Fieldbus) are available.
The SAFEMASTER PRO DESIGNER software is capable of creating complex logics, using logical operators
and safety functions such as muting, timer, counters, etc.
All this is performed through an easy and intuitive graphic interface.
The configuration performed on the PC is sent to the control unit UG 6911.10 (or UG 6911.12/080) via USB
connection; the file resides in the control unit uand can also be saved on the proprietary OA 6911 memory
chip (accessory). The configuration can therefore quickly be copied to another control unit UG 6911.10
(or UG 6911.12/080).
The modules UG 6912.04/100, UG 6915/008 and UG 6915/016 are available from UG 6911.10 firmware
version 3.0 or higher.
The SAFEMASTER PRO system is certified to the maximum safety level envisaged by the applicable
industrial safety standards (SIL 3, SILCL 3, PL e, Cat. 4).

MULTIPLE LOAD function
RESTORE Function
To perform the configuration of several control units UG 6911.10 (or UG 6911.12/080) without using a PC and
the USB connector, you can save the desired configuration on a single memory chip OA 6911 and then use it to
download data on the control unit UG 6911.10 (or UG 6911.12/080) to be configured.
If the control unit UG 6911.10 (or UG 6911.12/080) is damaged, you can replace it with a new one; having
already saved all the configurations on the memory chip OA 6911, all you need to do is insert the memory
chip OA 6911 in the new control unit UG 6911.10 (or UG 6911.12/080) and switch on the SAFEMASTER PRO
system, that will immediately load the backup configuration.In this way, the work interruptions will be minimized.
If the file contained in the memory chip OA6911 is not identical to the one contained in control unit
UG 6911.10 (or UG 6911.12/080), an overwrite operation that will permanently delete the configuration
data contained in the control unit will be performed.
WARNING: ALL DATA PREVIOUSLY CONTAINED INTHE CONTROL UNITSWILL BE LOST.
Each time the memory chip OA 6911 is used, carefully check that the chosen configuration is the one
that was planned for that particular system. Try again a fully functional test of the system composed of
SAFEMASTER PRO plus all devices connected to it (see the TESTING the system section).
The LOAD and RESTORE functions can be disabled via software (see "Create a new project (configure
the SAFEMASTER PRO system)".
In order to be used, the expansion units must be addressed at the time of installation (see the NODE SEL
section.
