The I/O module 750-666/000-003 shall only be installed and operated according
to the instructions in this manual and in the manual for the used fieldbus
coupler/controller.
Consider power layout of the WAGO-I/O-SYSTEM 750!
In addition to these operating instructions, you will also need the manual for the
used fieldbus coupler/controller, which can be downloaded at www.wago.com.
There, you can obtain important information including information on electrical
isolation, system power and supply specifications.

3 PROFIsafe
PROFIsafe is a protocol for secure 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 (PROFIsafe 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.

Manual
Version 1.4.0, valid from HW/SW Version 01/01
Data is exchanged between the secure PROFIsafe I/O modules and the safe PLC
via PROFIBUS or PROFINET as the physical 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 PROFIsafe
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 internal bus in the node to the I/O module. The PROFIsafe
telegrams are only evaluated in the safe PLC and in the PROFIsafe module.
When detecting communication errors, the PROFIsafe I/O modules are passivated
in that all secure 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 PROFIsafe 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 (Handbook PROFIBUS Installation Guideline,
current version)

The iPar parameters are used to configure device functions of a safe device such
as the PROFIsafe I/O modules of the WAGO-I/O-SYSTEM 750/753. The
“WAGO Safety Editor 75x” parameterization tool (SEDI) can be used to set the
individual parameters of WAGO PROFIsafe I/O modules. SEDI is the CPD tool
for WAGO PROFIsafe 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

The safe PROFIsafe 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 PROFIsafe I/O modules can be seamlessly integrated into the
