Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.

4.2 Supply voltage
}Module supply
– supplies voltage to the head module
– supplies voltage to downstream modules (right-hand side)
}Periphery supply
– supplies voltage to the sensors, actuators and test pulses
When the supply voltage is fed in separately, the module supply and periphery supply are
galvanically isolated. If galvanic isolation is not required, a common power supply may be
used for the periphery supply and module supply.
Ensure you comply with the maximum output power of the module supply and periphery
supply (see "Technical details [ 34]"). If the power consumption is higher, an additional
supply voltage module is required to refresh the periphery supply. The module supply can-
not be refreshed.
}Module supply
The total power consumption of all module racks and electronic modules must be ≤ the
maximum output power.
}Periphery supply
The total power consumption of the sensors, actuators and test pulses supplied via the
input/output modules must be ≤ the maximum output power.
If the periphery supply is missing, the "PWR" LED flashes and a message is entered in
the diagnostic list.

4.3 Integrated protection mechanisms
The module has the following protection mechanisms:
}multi-channel diverse processor section
}cyclical self tests
}potentially isolated interface
Buffering:
Module supply failures are buffered for 20 ms.
4.4 MicroSD card
If you use the optional removable data medium, then data that is relevant for the device ex-
change will be stored on the data medium.
NOTICE
The microSD card includes safety data. Ensure that the microSD card is
plugged in before commissioning. To ensure that final data are stored on
the data medium, do not remove the microSD card before completing the
commissioning.
When a device is changed, the stored data can be copied over using the Reset button (see
Reset button [ 12]).
4.5 Reset button
Carrying out a warm reset (restart)
Procedure:
}Press the Reset pushbutton for less than 5 seconds.
Performing a cold start/reboot command initiates the following procedure:
}Processing is aborted
All LEDs apart from the “PWR” LED are shut down
}System is initialised
Head module is ready for operation and the "MS" LED flashes green
}System switches to "Operational" state
Head module is in operation and the "MS" LED lights up green
}Operational entry in the error stack
Impact after a restart:
}Inputs retain their current input values
}Substitute values are used for the outputs until the connection to the controller has been
re-established.

Copying the device project from the removable data medium to the PSSu2 system
Prerequisites
}A removable data medium must be plugged into the PSSu2 system.
}The removable data medium may not be empty or defective.
}The device project on the removable data medium must match the product type.
Procedure:
}Press the Reset pushbutton for more than 5 seconds. The SD LED flashes yellow.
}Release the Reset pushbutton, then press and release it again within 10 seconds.
}The device project will be copied from the removable data medium to the device.
If the required files are not on the removable data medium, the device exchange scenario is
not performed and an entry is written in the error stack.
If no removable data medium is inserted, an original reset is performed.
}Default values:
– IP address: 192.168.1.1
– Subnet mask: 255.255.0.0
– Gateway address: 192.168.1.1
Effects of the original reset:
}ST and FS configuration data is deleted
}Error stack is not deleted
}The head module is restarted automatically.
4.6 EtherNet/IP
4.6.1 Connection to EtherNet/IP
Decentralised input/output
}The head module enables the PSS u2 to be used as a modular, decentralised input/out-
put module.
}The head module receives signals from a higher level control system; it processes these
signals and passes them on to the connected input/output modules.
}The head module receives signals from the connected input/output modules; it processes
these signals and passes them on to a higher level control system.
All the project data is stored in the head module.
4.6.2 Setting the IP address
The IP address can be set using the DIP switch or using PASconfig (see online help for
PASconfig).
Setting via the DIP switch
The DIP switch has precedence over the setting in PASconfig. The IP address set in PAS-
config is only used if the DIP switch is set to 0 or 255.

Function description
Operating Manual PSS u2 P0 F/S EIP
1004528-EN-03 | 14
The DIP switch only allows the last byte of the IP address to be set (192.168.1.xxx ). xxx is
the value that can be set with the DIP switch.
Subnet mask used: 255.255.255.0.

Function description
Operating Manual PSS u2 P0 F/S EIP
1004528-EN-03 | 15
The DIP switch is binary coded. An IP address is set via a combination of the relevant bin-
ary coded switches:
“IP-ADDRESS” DIP switch Meaning Example
Switch designation ON OFF IP address 192.168.1.52

4.6.3 Projects
To configure the head module you will need the RSLogix 5000 software or Studio 5000 Lo-
gix Designer from Rockwell and PASconfig. To simplify configuration, you can export the
PSSu2 configuration from PASconfig to a *.l5x file and import it into RSLogix from Version
30.

4.6.5 ST process image
Instance 101 in the Assembly Object (0x04) is used for the process image of the ST out-
puts.
Instance 104 in the Assembly Object (0x04) is used for the process image of the ST inputs.
The sequence of the data in the process image depends on the slot number (beginning with
slot 1). The length of the ST process data depends on the number of configured ST mod-
ules. If a module has a process image, the process image always occupies at least 1 byte,
even if not all bits are used.
The valid bits of the ST outputs are transferred in the process image of the ST inputs.

4.7 CIP Safety
System limits
The process image for the FS modules always occupies at least 1 Byte for the FS input or
FS output data, even if all the bits are not used. This results in the following system limits:
}A maximum of 12 FS modules can be used
}A maximum of 4 FS input modules of type PSSu2 EF 8DI can be used
}A maximum of 8 FS output modules can be used
4.7.1 FS process image of inputs
In the process image of the FS inputs, the Combined Input Status (CIS) is used to indicate
whether all FS input modules supply valid values.
}CIS = 0: Not all FS input modules supply valid values
}CIS = 1: All FS input modules supply valid values
In the process image of the FS inputs, the Combined Output Status is used to indicate
whether all FS output modules deliver valid values.
}COS = 0: Not all FS output modules deliver valid values
}COS = 1: All FS output modules deliver valid values
From byte 10 the process image of the FS inputs is used for the valid bits of the FS output
modules.
Maximum length of the process image of the inputs: 18 bytes
INFORMATION
In the event of an input error, the valid bits for all inputs of all FS input mod-
ules are set to “0”.
In the event of an output error, the valid bits for all outputs of all FS output
modules are set to “0”.

4.7.3 Restart interlock
The grouping of the FS inputs/FS outputs is determined by the user program in the control
system.
The Combined Input Status (CIS) and Combined Output Status (COS) bits (see FS process
image of inputs [ 18]) have the value “0” if one of the FS inputs or one of the FS outputs
is faulty. Once an error at the FS inputs or FS outputs has been rectified, the modules are
operational again immediately and the value of the status bits automatically changes to “1”.
The CIP Safety Protocol does not contain any restart interlock. The restart interlock must
be configured in the user program.
FS inputs
Example of the configuration of a restart interlock:
}In the user program of the programmable safety system, the value for CIS=0 must be
saved in a control variable.
}The user program must link this control variable logically to every safe input with AND.
