2.3 Installation on a higher-level controller
2.3.1 Device master file (GSD) and symbol files
A device master file (GSD) is needed for configuration and
programming of the bus node with a programming unit or PC.
The GSD includes all required information for adjustment of
the bus node using configuration and programming software,
e.g. Siemens SIMATIC STEP 7.
Procurement source Current GSD and symbol files can be found on the Festo web-
site at www.festo .com Support/Downloads Search
“GSD”.
GSD files You will require one of the following files for the bus node:

2.4.2 Configuration of a DP master
The bus node can be controlled by commercially available
programmable logic controllers (PLC) aw well as PCs and industrial PCs with a PROFIBUS-DP interface in accordance with
EN 50170. The corresponding programming and commissioning software of your PLC manufacturer is required for commissioning.
Configuration of the bus node with a PLC from Siemens is
described in chap. 2.4.4.
2.4.3 Bus start-up
In order to commission the mounted and connected bus
node, the master must carry out the following functions in the
corresponding sequence:
1. Request diagnostic information
2. Send parameterisation data (Set_Prm)
For the start parameterisation, the parameter set is
loaded by the master into the bus node. The bus node
distributes the parameters to the connected equipment.
3. Check configuration data (Chk_Cfg)
4. Transfer input and output data (cyclical data exchange,
Data_Exchange)
5. Read diagnostic information (Slave_Diag)
The structure and contents of the individual telegrams are
described in the appendix.
2-16
Note
After each interruption of fieldbus communication, the
parameter set is resent to the bus node by the master.

2.6.4 Bus node parameters tool change
The tool change mode (GSD: “T ool Change Mode”) offers the
option to integrate or replace I-Port devices flexibly. Merely a
universal data range is created, which a device can occupy.
Which equipment is then actually connected is not defined.
As a result, a flexible replacement of different equipment is
possible. In this case, any I-Port devices are recognised
without an error message as long as their real process data
size does not exceed the configured size.
Through a universal module (see Tab. 2/1), a fixed maximum
I/O data length is assigned to each I-Port connection on the
respective module or slot position (Siemens). This ensures
that the right module configuration, i.e. sufficient data length,
is also queried after every switch-on.
In the parameters of the bus node, the tool change mode can
be activated for each I-Port connection individually.
2-34
Festo P.BE-CTEU-PB-OP+MAINT-EN en 1208NH English
2. Commissioning
The following cases of the tool change mode can be differentiated:
Case
Connect/remove or link/separate device in ongoing operation
Tool change mode off Tool change mode on
If a device is separated from the
I-Port connection during operation, the “Device disconnected”
diagnosis becomes active.
This error is automatically reset
as soon as the connection to the
device is restored.
If a device is connected to an
I-Port connection during operation, th e bus node issues an error (“Device wrongly connected”).
This error is automatically reset
as soon as the connection to the
device is separated again.
If a device was already found at
the I-Port connection during
switch-on, the “Device disconnected” diagnosis is active as
long as the connection to the
device is/becomes separated
during operation.
This error is automatically reset
(diagnosis “Device reconnected”) as soon as the connection
to the device is restored.
A fixed address space is reserved in the image table for
both I-Port devices. As soon as a
device is detected at one of the
I-Port connections, its I/O data
are mapped into the image
table.
Diagnostic messages are not
generated when there is no connection to the device nor in case
of configuration errors (e.g. I/O
length of the device is larger
than I/O length of the tool
change mode).
If a device is connected to an
I-Port connection during operation, the device is recognised
but no error message is generated.

2.8 Fail state behaviour
Fail state regulates the behaviour of the bus node and the
connected equipment in the event of communication malfunctions.
Parameterisation The behaviour of the bus node is dependent on the DIL switch
setting (see chap. 1.4) and the configured behaviour of the
master in the case of:
– telegram failure
– interruption of the fieldbus line
Depending on the parameterisation, the outputs (valves and
electric outputs) will be switched off (factory setting),
switched on or retain their status (see Tab. 2/10).
Warning
An incorrect status of the valves and outputs can lead to
dangerous situations!
•
Ensure that valves and outputs are put into a safe status
if the stated malfunctions occur.
Note
Please observe the following if the outputs are reset in the
event of fieldbus interruptions or malfunctions:
– Monostable valves move to the basic position
– Bistablevalvesremaininthecurrentposition
– Mid-position valves go into mid-position (pressurized,
exhausted or closed, depending on valve type).

2.9 Switching on
This chapter includes fundamental instructions for commissioning the bus node.
Detailed instructions and further information can be found in
the documentation or online help for the controller or control
program that you use.
2.9.1 Information concerning the switch-on behaviour of the bus node
Warning
Danger of injury through uncontrolled movements of connected equipment.
Make sure that electrical and pneumatic equipment are in
a de-energised and pressureless status.
Before working on the pneumatics:
•
Switch off the compressed air supply
•
Vent the valve terminal
Before working on the electrical components, e.g. before
installation or maintenance work:
•
Switch off power supply
In this way, you can avoid:
– uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the connec-
ted actuators
2-42
– undefined switching states of the electronics
Festo P.BE-CTEU-PB-OP+MAINT-EN en 1208NH English
2. Commissioning
Note
The configuration set at the master must agree with the
equipment actually connected at the bus node.
If there are deviations in the configuration, no data exchange takes place between master and bus node (BF-LED
flashes red slowly).
Observe the following instructions about switch-on behaviour:
•
Disconnect the operating voltage from the bus node before replacing equipment, as the configuration is retransmitted from the master at the restart.
•
Equipment must already be connected to the bus node
before switch-on, or an error message will result and no
process data will be exchanged.
•
Special case, tool change mode (chap. 2.6.4):
In this case, any I-Port device is recognised without an
error message as long as the real process data size does
not exceed the configured size.
2.9.2 Checklist before swit ching on
The following conditions must be fulfilled:
– DIL switch settings have been made (see chap. 1.4).
– Fieldbus connecting cables are connected (see chap. 1.5).
– Installation and configuration have been performed com-
pletely (see chap. 2.3 and 2.4).

3.4.2 Diagnostics with Siemens SIMATIC S7
With controllers from Si emens and other manufacturers, you
have the ability to specify the behaviour of the bus node in
case of malfunctions (for details see product documentation
on the respective controller).
You can set one of the two types of diagnostic behaviour:
– Hard characteristics in case of malfunction: The controller
switches to the operating mode “STOP” when an error
occurs
– Smooth characteristics in case of malfunction: The con-
troller remains in the operating mode “RUN” when an
error occurs
