Note...................................

Data transmission errors

Malfunction:
If installation has not been carried out correctly and if
high baud rates are used, data transmission errors may
occur, e.g. as a result of signal reflections and attenu
ations.
 Connect screening to all network cables
 Wherever possible, only ground screening once (“star

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.

Note...................................

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 par ticipants
(“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 fo rm “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)”).

individually using parameterisation (“Module paramet
erisation”), e.g. input debounce time, signal extension
time, product monitoring, (forwarding of diagnostic mes
sages), settings for error situations (“Fail-state” mode).
Parameterisation for “I-port device” 1 (X1) and “I-port
device” 2 (X2) can be set separately.

Example “Universal device 256DIO”

Tool Change Mode Tool change mode:

– “Tool Change Mode” enabled:

The process data image rigidly assigns
address spaces for input and output
data (addressed) – regardless of which
product is connected (“I-port device”),
meaning that the connected products
(e.g. tools) can be interchanged without
the need for any configuration changes.

– “Tool Change Mode” disabled:

The “I-port device” detected at start-up
is adopted by the PROFINET configura
tion. The assignment (addressing) of in
put and output data in the process data
image depends on the connected
product.

(“Suppress missing load voltage diagnostic

Fail-state The “Fail-state” mode governs the charac

teristics of the bus node and the connected
products in the event of any communica
tion errors arising:
– Reset outputs (“Outputs reset”): The

outputs are reset.

– Outputs “Hold last state” (“Outputs

Hold last state”): The outputs hold their

last state.
The selected setting applies to all outputs.
The “Fail-state” setting also applies to the
“Idle state” operating state:
– The “Idle state” is adopted by the con

trol system on request. At this point, the

control system is in “Stop mode”.
– Input data continue to be transmitted

while the system is in “Idle state”.

Network-specific characteristics

Network protocol PROFINET IO:

– based on Industrial Ethernet
– based on the standard Ethernet

protocol (IEEE 802.3)

Supported protocol
characteristics and
protocol functions
(selection)

– Cyclical data exchange “in real time”,

without cycle synchronicity (Real-Time,
RT) or with cycle synchronicity
(Isochronous Real Time, IRT)

1)

– Link Layer Discovery Protocol (LLDP)
– Simple Network Management Protocol

(SNMP)
– Fast Start-up (FSU)
– PROFIenergy
– Shared device
– Media Redundancy Protocol (MRP)

System-specific
functions

– Diagnosis information (system

diagnosis, undervoltage,

communication errors)
– Web server (status of bus node and

connected products, serial number,

configuration)

Specification Selection of directives and norms

regarding PROFINET:
– PROFINET installation guidelines

(“PROFINET Installation Guide”,

“Installation Guideline PROFINET

Part 2…”).
– IEC 61158
– IEC 61784
– IEC 61918
