3 PROFIsafe
PROFIsafe is a protocol for safe communication, and is certified in accordance
with IEC 61784-3-3.
For the WAGO-I/O-SYSTEM 750, I/O modules were developed with safety-
related inputs and outputs (F I/O modules) without any drastic changes to the
existing series 750 system, making mixed operation of safety-related and non-
safety-related I/O modules possible.
Figure 1: Mixed Operation of Safety-Related and Non-Safety-Related I/O Modules
A safe PLC (PROFIsafe and PROFIBUS or PROFINET master) is used with
PROFIBUS or PROFINET interface as the controller.

750-667/000-003 4FDI/4FDO 24V/2A PROFIsafe V2 iPar
Manual
Version 1.4.2, valid from HW/SW Version 01/02
Data is exchanged between the secure F I/O modules and the safe PLC via
PROFIBUS or PROFINET as the basis. Data is exchanged in the form of
PROFIsafe telegrams that correspond to the PROFIsafe protocol profile IEC
61784-3-3.
Figure 2: PROFIsafe Layer Model
The PROFIsafe telegrams are transferred between the safe PLC and
F I/O module via the so-called "black channel". The "black channel" extends from
the PROFIBUS or PROFINET connection of the PLC via the fieldbus
coupler/controller, the local bus in the node to the I/O module. The PROFIsafe
telegrams are only evaluated in the safe PLC and in the F I/O module.
When detecting communication errors, the F I/O modules are passivated in that
all safe outputs are switched off and the "0" is transferred to the safe PLC as an
input process image.
Evaluation of the input process image and output of the output process image via
the F I/O modules with digital outputs are controlled by the safe PLC.
Note the following guidelines and information when setting up PROFIsafe
applications:
• Guideline PROFIsafe - Requirements for Installation, Immunity and electrical
Safety (PROFsafe Environmental Requirements, current version)
• Installation recommendations (PROFIBUS Installation Guidelines, current
version)

3.1 Individual Parameters
The individual parameters are used to configure device functions of a safe device
such as the F I/O modules of the WAGO-I/O-SYSTEM 750. The “WAGO Safety
Editor 75x” parameterization tool (SEDI) can be used to set the individual
parameters of WAGO F I/O modules. SEDI is the CPD tool for WAGO F I/O
modules.
It is often required during a repair to quickly replace a device without using
additional manufacturer tools for parameterization of the device functions.
To meet this requirement, the iPar server is used that offers appropriate services
for saving and restoring individual parameters. The “iPar Server” is available as a
function block or as a system function within the non-safety related part of the
safe PLC.
Further details about using the iPar server in conjunction with the WAGO F I/O
modules are available in an application note.

</dg_
The safe F I/O modules are intended for functional safety in the area of industrial
automation technology, building technology and process technology to protect
man and machine according to Machinery Directive 2006/42/EC.
The PROFIBUS DP and PROFINET IO fieldbus can be used to connect to the
safe PLC. The F I/O modules can be seamlessly integrated into the existing
WAGO-I/O-SYSTEM 750.
Expensive and inflexible cabling are replaced by flexible configurable safety
functions by secure PROFIsafe data transmission via the existing fieldbus
system. It is then possible to optimize the F I/O module to different safety
applications.

Observe the information on the power supply concept!
Detailed information and examples for supplying PROFIsafe I/O modules is
available in the section “Connect Devices” > … > “Power Supply Concept”.
The I/O module 750-667/000-003 (4FDI/4FDO 24V/2A PROFIsafe V2 iPar)
receives the 24 V voltage supply for the field level from an upstream I/O module
or from the fieldbus coupler/controller via blade-formed power jumper contacts. It
then provides these potentials to subsequent I/O modules via spring-formed
power jumper contacts.
The field voltage and the system voltage are electrically isolated from each other.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
The PROFIsafe I/O module 750-667/000-003 can be operated on the
WAGO-I/O-SYSTEM 750 fieldbus couplers specified in section “Technical Data”
