Warning
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Electrical voltage
Injury caused by electric shock, damage to machine
and to system.
For the electrical power supply, use only PELV circuits
in accordance with IEC60204-1 (Protective Extra-
Low Voltage, PELV).
Observe the general requirements IEC60204-1 of
the PELV power circuits.
Only use power sources that guarantee reliable elec
trical isolation of the operating and load voltage in
accordance with IEC60204-1.
Always connect all circuits for operating and load
voltage supplies U
EL/SEN
and U
VAL/OUT
.
Fuse protection
The bus node also supplies operating and load voltage to
products connected via the I-port interface.
Secure operating voltage U
EL/SEN
and load voltage
U

separately.
Take due account of the current consumption of con
nected products during design and protection of the
power supply.
Observe power rating of power supply (no bus node-in
ternal overload protection for the connected products)
è
Section 10.
Ensure correct polarity (no bus node-internal reverse
polarity protection for the connected products).
Potential equalisation (earthing measures)

Unauthorised access
to the product can cause damage
or malfunctions.
When connecting the product to a network:
Protect the network from unauthorised access.
Measures for protecting the network include:
– Firewall
– Intrusion Prevention System (IPS)
– Network segmentation
– Virtual LAN (VLAN)
– Virtual private network (VPN)
– Security at physical access level (Port Security).
Further information:
è
Guidelines and standards for security in informa
tion technology, e.g. IEC 62443, ISO/IEC 27001.
An access password protects only against accidental
changes.
Use of switches and routers
When using the PROFINET function “Fast Start-up” (FSU):
Only use switches and routers that support the “Fast
Start-up” function.
Connect up network participants (“IO devices”) and
network components via LAN (“wire-bound”)
(no support of “Fast Start-up” by Industrial Wireless
LAN Access Points, IWLAN).
Use of crossover cables
When using patch cables and crossover cables in the
same network:
Ensure that the crossover detection (“Crossover Detec
tion”, “Auto-MDI” or “Autocrossover/Autonegotiation”)
is enabled in the control system.

5 Commissioning, configuration and parameterisation
Commissioning, configuration and parametrisation of the
bus node is dependent on the primary control system
used. The basic approach and required configuration data
are explained in the following sections.
Warning
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Uncontrolled movement of the actuators, loose tubing,
undefined switching states of the electronics.
Injury caused by moving parts, damage to machine and to system.
Before commissioning, ensure that the connected
products do not perform any uncontrolled
movements.
Observe commissioning notices in the control system
documentation.
No automatic checking of configuration and
parameterisation: The bus node and the connected
products also go into operation if configuration is
incorrect.
5.1
Switching on the power supply
If the control system and network participants have sep
arate voltage supplies, the devices must be switched on
in the following sequence:
1. Switch on power supply to all network participants
(“IO Devices”).
2. Switch on power supply to control system.
5.2
Addressing
PROFINET uses module-oriented addressing, i.e. each
network participant is addressed separately (in contrast
to block-oriented addressing of other fieldbus systems).
The controller uses the following for addressing:
– Fieldbus device names, short form “Device Names”
è
Section 5.6
– IP addresses
è
Section 5.7
– Input/output addresses (I/O addresses)
è
Section 5.9.
Note
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Addressing errors
Incomplete faulty configuration, malfunction, fault in
dication
The address space of the bus node is limited
(
è
Section 10, Technical data).
Determine the number of assigned inputs and out
puts prior to commissioning.
Basic rules for addressing
– Addressing:
Module-oriented, byte-by-byte
. Modules
with less than 8 bits occupy 8 bits of address space
and/or 1 byte of address space, but which do not use
all this space.
– The address assignment of the inputs does
not depend
on the address assignment of the outputs.
5.3
Import device master file (GSDML file)
A device master file (GSD) in XML format (GSDML) is
needed for configuration, parameterisation and program
ming of the bus node. The GSDML contains all information
required to connect into the hardware configuration of
the control system, e.g. Siemens SIMATIC STEP 7.
Download of the GSDML file
è
www.festo.com/sp
1. Enter search term: “GSDML”.
2. Click “Firmware and drivers” tab.
3. Click “File and language versions” link.
4.Transmit file “GSDML-V...-Festo-CTEU-...zip” to the con
trol system and unpack it.
The file contains:
– one or more GSDML files
(GSDML-V...-Festo-CTEU-...xml)
– a symbol file (GSDML-...-...-CTEU.bmp)
– optionally a “Read Me” file with notes on the current
GSDML versions.
Observe comments in the “Readme” file.
Installation of the GSDML file
è
Documentation of the control system
After installation of the GSDML file, all available network
participants (“IO devices”, bus nodes) and field devices
(“Field devices”), e.g. products with an I-port interface
appear in the hardware directory of the control system
(“Catalog”).
Example of Siemens SIMATIC S7-1200, TIA portal:
Install GSDML file (“Install general station description
file (GSD)”).
