Valve terminal type VTOC-PT-L en. . . . . . . . . . . . . . . . . . .
1 Intended use
The valve terminal VTOC with interlock (type VTOC-PT-L) is
used exclusively for control of pneumatic actuators within the
limits of the technical data and is intended for installation in
machines and automation systems.
The VTOC-PT-L is intended for use in an industrial environ-
ment.
The target group of this description consists of trained spe-
cialists in control and automation technology who have ex-
perience with the installation of valve terminals.
Warning. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Danger of injury through uncontrolled movements of con-
nected 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 the power supply
In this way, you can avoid:
– uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the
connected actuators
– undefined switching states of the electronics
– functional damage.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Installation and commissioning should only be carried out
by qualified personnel in accordance with this brief de-
scription. Commission a valve terminal only if it has been
completely mounted and wired! Employ the valve terminal
VTOC-PT-L only in conformity with protection class IP40.

4 Earth terminal
Connect the VTOC-PT-L to functional earth via the earth
terminal (

1in the figure in section 2). In this way, you
will avoid malfunctions from electromagnetic interference.
5 I-port connection
The VTOC-PT-L can be connected as follows via the I-Port
connection:
– directly to the fieldbus by mounting a CTEU bus node on
the VTOC-PT-L
– decentralised to an external I-Port-compatible device
through a connecting cable.
– to a CPX terminal through a connecting cable and a CTEL
master module ( CTEL system description).
6 Voltage supply
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
• Use for the electrical power supply only PELV circuits in
accordance with IEC/EN 60204-1 (Protective Extra-Low
Voltage, PELV).
• Observe also the general requirements for PELV circuits
in accordance with IEC/EN 60204-1.
• Use only voltage sources that ensure a reliable electric
separation of operating voltage in accordance with IEC/
EN 60204-1.
• Always connect both circuits for operating and load
voltage supply.
Through the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is en-
sured in accordance with IEC/EN 60204-1.

7 IO-Link mode
The VTOC-PT-L can also be operated as an IO-Link device. You
can download the IODD configuration file required for this at

www.festo.com.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
If an IO-Link Master is used, the load voltage must
normally be made available through a T-plug.
8 Bridged interlock
For applications that do not require control of the solenoid
coils via interlock, the interlock D-sub connection can be
bridged with a special D-sub socket (type NEFF-S1G44LB). All
solenoid coils are then supplied with load voltage through
the I-Port.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
– This D-sub socket is intended only for bypassing the
interlock.
– In the D-sub socket of type NEFF-S1G44LB, the load
voltage sockets (24 V) are bridged with the sockets (V+).
– The D-sub socket of type NEFF-S1G44LB cannot be used
as a multi-pin plug socket.
9 Address assignment
With the VTOC-IL, you can actuate up to 48 solenoid coils.
The subsequent figure shows an example of the address
allocation of the VTOC-PT-L valve terminal with 12 valve posi-
tions (VP):
–
1
assigned addresses of the solenoid coils 12
–
2
assigned addresses of the solenoid coils 14
– The address assignment is independent of whether blank-
ing plates
3
or valves
4
are used.
– Address assignment is in ascending order without gaps,
from left to right.
– A valve position always occupies two addresses. The fol-
lowing assignment applies in this case:
– Low-order valve position (address) for solenoid coil 14
– High-order valve position (address) for solenoid coil 12.

11 Malfunction and error handling
Malfunctions and statuses from connected I-Port devices are
transmitted in the form of event codes through the bus node
to the Fieldbus Master and output there and stored, if neces-
sary. In the diagnostics case, a 2-byte-long event code is
transferred to the I-Port or IO-Link master.

13 Interlock
The first 16 solenoid coils can be supplied individually
through the interlock D-sub connection. This permits the
external release of these valves.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Mount or remove the interlock D-sub connection only in a
free-of-tension status.
The interlock can be switched on as follows:
– single-pin through external contacts
– double-pin through safe output terminals. In this case,
check the compatibility of the safe output terminals with
the VTOC-PT-L.
All valves of the VTOC-PT-L are supplied with load voltage
through the interlock D-sub connection, even if actuated
through the bus node. The solenoid coils 17 … 32 and
33 … 48 cannot be supplied individually through the interlock
D-sub connection (

table in the section 13.3 and 13.4).
13.1 Sub-D socket
Festo recommends one of the following cables (with sub-D
socket) from Festo for connecting the interlock.
Type Length of the cable
NEBV-S1G44-K-2.5-N-LE44-S6
2.5 m
NEBV-S1G44-K-5-N-LE44-S6

10 m
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Observe when using sub-D plugs of other manufacturers:
– The sub-D plug must not exceed a max. width of
16.5 mm
– Connect the cable screening to the plug housing
13.2 Pin allocation of the interlock (sub-D 44 pin)

lock sub-D connection:

13.3 Single-pin interlock interface
Observe the following with single-pin interlock interface:
– The interlock interface is made through external plus
switching contacts or single-pin switching safety terminals.
– The 24 V supply of all solenoid coils must be on the same
potential.
– 16 solenoid coils can be actuated through the interlock
(V
n
+).
– The solenoid coils that do not require an interlock interface
can be supplied directly with 24 V from pin 1 … 3.
– Creation of the respective input voltage is reported as an
image table through the fieldbus.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The interlock contacts V

must not be used with
the single-pin interlock interface.
13.4 Double-pin interlock interface
Observe the following with the double-pin interlock interface:
– The interlock interface is made through external plus-
minus switching safety terminals.
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The internal control of valves 1 … 16 over the fieldbus must
not be used.
An inadvertent switch-on of the internal drivers of the
VTOC-PT-L over the fieldbus can be recognised by most
safe terminals. Use only terminals that recognise an inad-
vertent actuation through the fieldbus.
– The solenoid coils of the interlock valves are controlled
through the corresponding pin in the sub-D plug
(pins 7 … 38).
– The solenoid coils that do not require an interlock interface
can be supplied directly with 24 V (e.g. from pin 1 … 3).
– A difference in potential between V
n
– and 0 V
VAL/OUT
is
permissible only below 5 V.
– The test impulses (
Å¡
1 ms) used for error detection by safe
output terminals are suppressed by a special filter switch.
– For the VTOC-PT-L, the current consumption per valve is
below 20 mA. Some safe terminals recognise wire break
with a current consumption below 20 mA. In these cases,
the wire break detection must be switched off.
