2Operating Manual
Introduction
This shortform explains the function and operation of the decentralised
input/output module PSS SB DI16.
The documentation is intended for instruction and should be retained for
future reference.
Validity of the documentation
The PSS SB DI16 documentation is valid from Version 2.1 onwards. It is
valid until new documentation is released. The latest documentation is
supplied with the unit.
Overview
The module provides 16 digital inputs and 4 dedicated test pulse outputs.
The inputs are suitable for connecting single or dual-channel safety-
related input devices, with or without test pulses. Inputs can be assigned
to two I/O-Groups in SafetyBUS p.
Each test pulse output has 4 terminals, which can also be configured in
pairs as 24 VDC terminals.
The PSS SB DI16 requires a 24 V supply, which feeds both the module
electronics and the dedicated test pulse outputs.
The module is galvanically isolated from SafetyBUS p via optocouplers.
NOTICE
Before installing the module you should read and consider the “PSS SB
DI16 Installation Manual” and the “SafetyBUS p System Manual”.

Operating Manual 3
Intended use
The PSS SB DI16 is a decentralised input module which has been
designed for use as an “Input/Output Device”on SafetyBUS p.
System requirements
CPU versions
Before using the module on SafetyBUS p you must ensure that all the
safety systems accessing the module can in fact support it. This means
that all safety systems with Logic Device functionality which are assigned
to I/O-Group(s) on the PSS SB DI16, and the safety system with Manage-
ment Device functionality, must all support the module.
The PSS SB DI16 is supported by all SafetyBUS p-compatible safety
systems in the PSS-range, although on the PSS-types listed below, only
from the version number stated:
• PSS SB CPU from Version 1.3
• PSS1 SB CPU from Version 1.3
• PSS SB 3006 IBS-S PCP from Version 1.2
• PSS SB 3056 from Version 1.2
System software versions
The following system software is required in order to configure the module:
• PSS WIN-PRO from version 1.0.0

Functions
Inputs
The inputs are suitable for connecting single and dual-channel input
devices, with or without test pulses.
Input signals must show a “High” of 24 VDC (+15 ... +30 VDC) and a “Low”
of 0 VDC (-3 ... +5 VDC). All inputs have input filters.
Input status is transmitted to the CPU on the PSS master via SafetyBUS p.
Yellow LEDs indicate the status of the inputs. An LED lights up as soon as
a “1” signal is present at the input.
Diagnostic circuitry checks the function of the inputs, including the input
filter. If an error occurs, all the outputs in the affected I/O group will be
switched off and the I/O-group will switch to a STOP condition. An error
telegram will then be stored on SafetyBUS p and the error will entered in
the PSS SB DI16 error buffer.
Where test pulses are not used, inputs with single-channel input devices
can be used in applications up to and including category 2 in accordance
with EN 954-1; in the case of dual-channel input devices, this extends to
category 3 applications. The device should be suitably wired to eliminate
the risk of a short circuit in the external wiring between the different inputs
and a short to the “Supply”.
Test pulses must be used for applications with single-channel input
devices above category 2 and applications with dual-channel input
devices above category 3.
Connection diagrams can be found in the “PSS SB DI16 Installation
Manual”.
Inputs can be allocated to two I/O-Groups. For further information please
refer to “Operation of the module on SafetyBUS p”.
Detecting signals at the inputs
To guarantee that a signal („0“-Signal or „1“-Signal“) is detected at an
input, it must be present for a certain period of time. This time must be
longer than the Event Timeout configured in the system software PSS
WIN-PRO. The presence of a signal will trigger a corresponding Event
Telegram.

PSS SB DI16
6Operating Manual
The presence of a signal (“0” or “1” signal) will be ignored if it does not
exceed the pulse suppression time of 300 µs. In this case, no Event
Telegram will be sent.
Signal change behaviour
If a signal change occurs at an input, the module will send an Event
Telegram. The module must then wait for the acknowledgement telegram
(ACK) from the Master-LD before it can send a new Event Telegram.
If another signal change occurs while the module is waiting for the
acknowledgement telegram, the module's response will depend on the
configured signal change behaviour.
Two behaviour modes may be defined:
• “Default”:
The signal change is not registered
• “Fast”:
Each signal change is stored in a FIFO telegram buffer. If the
acknowledgement telegram arrives, the module will send an Event
Telegram from the FIFO telegram buffer for each signal change
detected.

Operating Manual 7
Test pulse outputs/24 VDC terminals
The four test pulse outputs T0to T3are used exclusively for test pulses or
as 24 VDC terminals. The test pulses are suitable for testing the wiring of
input devices. Only inputs which operate in accordance with the zero
signal principle (on switching off) are permitted for safety-related
applications.
Test pulses are allocated to inputs via the configurator in the programming
device.
Each test pulse output has four terminals, which are divided into two
terminal pairs. If a terminal pair is not being used for a test pulse it can be
used instead as a 24 VDC terminal. The use of terminal pairs is also
established via the configurator in the programming device. All terminals
are configured as 24 VDC terminals in the default setting.
Each terminal pair has a maximum load capacity of 0.5 A, irrespective of
its use.

Operating Manual 9
Operation of the module on SafetyBUS p
The module is connected to SafetyBUS p via a male 9-pin D-Sub
connector. Fibre-optic couplers from Pilz (like PSS SB SUB-D F0) can be
connected to the SafetyBUS p interface.
To enable the module to operate on SafetyBUS p, it must be given the
device address set via the configurator in the system software. Device
addresses 32dec ... 95dec are permitted if you are using the device in
conjunction with a Pilz PSS.
The configurator in the system software is also used to establish which I/O
groups the device belongs to.
The module can be divided into Section A and Section B. Section A and
Section B may belong to different I/O-Groups. The module itself can either
have Section A only, Section B only, or both Section A and Section B.
Input may be assigned to either section, as required.
The I/O addresses which the PSS master uses to address the inputs are
established according to their membership of Section A or B and the
device address.
Under the device address in the process I/O image of the PSS master,
inputs from Section A are addressed as slot number and bit number 0 ...
15. Inputs from Section B are addressed under the device address as slot
number and bit number 16 ... 31; this corresponds to an offset of 16 in the
bit number.
For example, if input I6from Section A is reconfigured to Section B, the
address will change from x.6 to x.22.
Example: Device address is 36

12 Operating Manual
Commissioning
General guidelines are given below, but you should always refer to the
“PSS SB DI16 Installation Manual” (this is part of the “Safety BUS p”
System Manual and is also enclosed with every Safety BUS p-compatible
PSS):
• Install the module
INFORMATION
If the module is attached to an earthed DIN-rail, this will automatically
cover the module's functional earth requirements.
• Wire the inputs and test pulse outputs
• Connect the module to SafetyBUS p and set the device address
• Connect the supply voltage.
Recommissioning
NOTICE
If the device has to be recommissioned you may experience errors when
inserting the terminal blocks, as these are not position-coded.
To ensure such errors are eliminated, always carry out a function test
when recommissioning.
Faults
If a module is defective or there is a wiring error, all the outputs in the
affected I/O group will be switched off and the I/O-group will switch to a
STOP condition. An error telegram will then be stored on SafetyBUS p
and the error will entered in the PSS SB DI16 error buffer.
An error message will appear on the PSS master’s display. The error
stack display in the programming device can be used to locate the error
(see “SafetyBUS p System Description”).
