INTRODUCTION
This technical data sheet describes the operation of the fieldbus modules of the configurable safety system
SAFEMASTER PRO:
UG6951 Fieldbus module (CANopen)
UG6952 Fieldbus module (PROFIBUS DP-V1)
UG6954 Fieldbus module (PROFINET)
UG6955 Fieldbus module (Ethernet IP)
UG6956 Fieldbus module (EtherCAT)
UG6957 Fieldbus module (USB)
The fieldbus module exports the system status and the status and diagnostics elements of all I/Os configured on the
SAFEMASTER PRO system.
These fieldbus modules have no influence on the safety functions of the configurable safety system
SAFEMASTER PRO.
ELECTRICAL CONNECTIONS,DIMENSIONS
Each module is provided with four connectors:
- 5 way IN-RAIL-BUS connector to the system SAFEMASTER PRO
- micro USB connector --> to the PC (for SW programming)
- BUS connector --> to the fieldbus
- Terminal block --> power supply

PROTOCOL DATAPACKAGE COMPOSITION
The fieldbus module exports the system status and the status and diagnostics elements of all I/Os configured on the
SAFEMASTER PRO system. Also import of eight inputs from fieldbus is possible.
The system status is shown as 1 byte:
-Bit 0 indicates whether the SAFEMASTER PRO is online/offline
-Bit 1 indicates the presence of diagnostics elements.
This byte is always present.
Each input and each output (OSSD) configured on the system is associated with two information elements: status
and diagnostics.
-Status is a binary value, 0 or 1
Each module with inputs has a number of bits corresponding to the number of physical inputs that are
present; thus modules UG6911.10, UG6913.08, UG6916.10 are associatedwith 1 byte, modules UG6913.12,
UG6913.16with 2 bytes.
The input byte location varies according to the type of modules that are installed, in the following order:
UG6911.10, UG6916.10, UG6913.16, UG6913.08, UG6913.12.
If several modules of the same type are installed the order follows the node number.
All safety outputs aresummarised in 1 or 2 bytes (depending onsystemconfiguration).
-Diagnostics is a code indicating the condition of the I/O, which can be OK or indicate a problem on the I/O.
Diagnostics elements are in the form of 2 bytes which indicate the index of the I/O with the problem and
the value of the diagnostics element.
If there is more than one diagnostics element, the relative values alternate every 500 ms.
Each set of information:
-input status,
-input diagnostics,
-fieldbus inputs status,
-fieldbus probes status,
-safety output status,
-safety output diagnostics
can be enabled/disabled in order to control the information and thus the number of output bytes exported to the
fieldbus.
One input byte with the whished state of fieldbus inputs must always be present, also if no fieldbus inputs are used in the
electric schema.
For the fieldbuses in which the mapping position is mandatory (i.e. PROFIBUS) the input byte must be mapped before the
output bytes.
For the fieldbuses based on CANOpen the data can be accessed only via PDO. SDO access is not supported.

DIAGNOSTICS
Each input and safety output is associated with a relative diagnostic code.
When the I/O is connected correctly the diagnostic code is OK and is not exported to the fieldbus;
if there is a problem on the I/O, the system exports 2 bytes to the fieldbus with:
-the index of the I/O in question
-the related diagnostic code
1. Byte: "I/O index"
This field indicates the number used to identify the I/O with a diagnostic code other than OK.
Possible values for this field are shown in Table 2.

EXAMPLESOFDIAGNOSTICS
Example 1
Figure 2
In the example shown in Figure 2, Input 1 (connected to module UG6911.10) is tested with the UG6911.10-T1
test signal.
During wiring, the 24Vdc is connected to input 1 instead of the UG6911.10-T1 test signal.
-The I/O index and Diagnostic code show the following values: 1 - 10 to indicate the diagnostics on
input 1 of module UG6911.10 (OUT_TEST error)
Example 2
Figure 3
In this example, the I/O index corresponds to the logical block and not to the physical terminal on module
UG6911.10.
In Figure 3 for example, the two-hand element connected to the Input 1 and Input 2 physical terminals
corresponds to I/O index No. 1 and the emergency stop connected to the Input 3 and Input 4 terminals
corresponds to I/O index No. 2.

Example 3
Figure 4
The example in Figure 4 is similar to example 1, except in this case Input1 is connected to module UG6913.16
and is tested with the UG6913.16-T1 test signal.
During wiring, the 24Vdc is connected to input 1 instead of the UG6913.16-T1 test signal.
-The I/O index and Diagnostic code show the following values: 1 - 10 (OUT_TEST error) to indicate the
diagnostics on input 1 of module UG6913.16
Example 4
Figure 5
In the example shown in Figure 5 the manual reset function is enabled on OSSD 1.
The E-Stop-button connected to input 1 is released without sending a reset command.
-The I/O index and Diagnostics code show the following values: 192 - 2
-to indicate the OSSD 1A/1B (Table 2: 192 = first output).
-to indicate the diagnostic code (Table 4: 2 = Waiting for OSSD to restart).

SOFTWARE BUS CONFIGURATOR"
The fieldbus module is configured via the micro USB interface on the front panel and using the "BUS
CONFIGURATOR"softwareon the SAFEMASTER PRO Designer CD-ROM.
This software allows configuring all fieldbus modules. It allows also the bi-directional communication of the
SAFEMASTER PRO systemwith a PC (using fieldbus module UG6957 for USB) or the display of the data, that is
transferredon the INRAIL-Bus of the SAFEMASTER PRO System(via the USB Port of the fieldbus modules). The
following picture demonstrates the possible connections:
Connection Example
Figure 6
It is important to point out the difference in behaviour oft the BUS CONFIGURATOR when communicating with the
modules UG6951 to UG6956 and the module UG6957 (USB):
•Module UG6951to UG5956:The software only allows the display of data that is transferred on the INRAIL Bus.
•Module UG6957:The software allows the bi-directional data transfer.Inthis case the operator cansetthe state of
the inputs “Fieldbus Input” directly from the computer.
CONFIGURATION
The module must be configured with the outputs disabled (outputs OFF).
Following parameters to exchange can be set:
- Input / output states
- diagnostic data
- bytes "fieldbus input" and "fieldbus output" used in the electric schema
- module address in the fieldbus network
- baudrate, in modules where this is envisaged
The address range depends on the type of fieldbus that is installed.
Module configuration can be queried at any time during module operation.
To configure the fieldbus module, proceed as follows:
1. connect the module via the IN-RAIL-BUS totheSAFEMASTERPRO system;
2. connect the SAFEMASTERPROsystemto the 24VDC +20% voltage power supply via the terminal strip;
ATTENTION: the master unit UG6911.10 must be without error state.
3. connect the USB cable to the PC and to the fieldbus module;
4. start up the "BUS CONFIGURATOR" software.
