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...6 valve locations are available for the
automation process.
The valve terminal with field bus connection 545
offers the following advantages:
•it can be connected to various control sys-
tems
•decentralized preprocessing relieves the con-
troller (PLC)
•less wiring due to two-core 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 field bus system 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
automation 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 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
slaves in a field bus system. They can be con-
nected to field bus modules of the following
automation systems:

minal with field bus connection as part of the
FPC 405 control system from Festo.

Explanation of the system structure
The FPC 405 controller is programmed by me-
ans of the Festo programming software FST
405. This software package enables user pro-
grams to be written in the programming langua-
ges STL (Statement List), LDR (Ladder Diagram)
and BASIC.
The software must be installed on a personal
computer (PC) which is connected via the dia-
gnostic interface of a processor module of the
FPC 405.
The field bus module E.CFA controls the comp-
lete exchange of information between the field
bus slaves (decentralized I/O modules) e.g. val-
ve terminal/valve sensor terminals, and the pro-
cessor modules of the controller.
The field bus slaves are connected via the field
bus interface on the field bus module. Three
physical lines (field bus cables) with up to 31
field bus slaves can be connected to the field
bus interface. With the Siemens module AS308-
3U two lines each with 32 decentralized I/O mo-
dules can be connected. With Klöckner-Moeller
control systems, the number of lines and the
number of field bus slaves per line depends on
the type of controller used. With the PS3 control-
ler, for example, up to three field bus slaves can
be controlled.

The field bus creates data communication be-
tween the controller and the field bus slaves
(e.g. valve terminal/valve sensor terminal) distri-
buted throughout the system. Data transmission
is made in accordance with standard RS 485.
Baud rates up to 375 kBaud can be set.
The valve terminal as a decentralized output
module processes the signals transmitted and
controls the actuators which are connected. The
valve terminal is supplied with current via an ex-
ternal power unit (AC 220V/DC 24V).
The valve sensor terminal as a decentralized
input/output module functions like a valve termi-
nal. It also processes up to 22 inputs.
The sensors register information (measured va-
riables) from the control process and pass this
on to the valve sensor terminal (further proces-
sing unit).
