IMPORTANT USER INSTRUCTIONS
This description contains instructions on the
possible dangers which can occur with the valve
terminal/valve sensor terminal.
A distinction is made between the following in-
structions:
WARNING
Indicates a potentially hazardous situation,
which, if not avoided, could result in death
or serious injury.
CAUTION
Indicates a potentially hazardous situation
which, if not avoided may result in minor or
moderate injury.
PLEASE NOTE
This means that this instruction must also
be observed.

SYSTEM STRUCTURE
Valve terminal
Festo offers a solution to automation problems at
the machine level in the form of the valve termi-
nal. Solenoid valves, solenoid pulse valves etc.
are ready fitted onto a connection block and
have already been tested. Valve terminals with
from 4 ... 14 valve locations are available for the
automation process.
The valve terminal with 1771 RIO offers the fol-
lowing advantages:
•decentralized preprocessing relieves the pro-
grammable controller
•less wiring due to 2-wire twisted pair cables
•clarity in system structure due to separation
of controller and machine
•valves already fitted
•wired valve solenoid coils
•central air supply
•central exhaust
•device already tested

A remote I/O link also offers the following ad-
vantages:
•a reduction in the number of output modules
in the controller
•economic data transfer over long distances
•high baud rate
•a large number of slaves can be linked into
the network
•error diagnosis is made easier
Valve sensor terminal
Complex automation tasks require the use of
sensors for which Festo offers the valve sensor
terminal. Solenoid valves, solenoid pulse valves
etc. are fitted onto a connection block and have
already been tested; two sensors per valve can
be connected on site. Valve sensor terminals
with from 4...14 valves are available for the auto-
mation process.
The valve sensor terminal includes all the advan-
tages of the valve terminal. It also offers:
•two inputs per valve location, e.g. for position
sensors
•two additional inputs
•two additional outputs, e.g. for electric actua-
tors, displays etc.

Valve terminal/valve sensor terminal in the
control system
The valve terminal/valve sensor terminals are
participants in the Allen-Bradley RIO link. They
can be connected to RIO scanner ports of the
following automation systems:

minal with RIO links connection as part of a A-B
control system.

nals are not compatible with the

The Allen-Bradley RIO link creates data com-
munication between the controller and the slaves
(e.g. valve terminal/valve sensor terminal or
remote I/O) distributed throughout the system.
Baud rates up to 57.6K, 115.2K or 230.4 K Baud
can be set.
The valve terminal as a decentralized output
device proceses the RIO signals transmitted and
controls the actuators which are connected. The
valve terminal is supplied with current via an ex-
ternal power unit (AC 115V/230 V/DC 24V).
The valve sensor terminal as a decentralized
input/output device functions like a valve termi-
nal. It also processes up to 30 inputs for valve
position sensors.
The actuators produce motion via air controlled
by the valve terminal/valve sensor terminal.
The sensors provide digital valve position infor-
mation and pass this on to programmable con-
troller through the terminal.
