Notes on function summary

The field bus node controls the following func-
tions:
•
connection of the valve terminal/valve sensor
terminal to the field bus module of the control
system and to further field bus slaves via the
field bus interface.
•
controlling data transfer from/to the field bus
module of the control system.
•
internal control of the valve terminal/valve
sensor terminal
The operating voltage connection and a
decoder are situated on the valve coupling unit
of the valve terminal. The decoder decodes the
signals received from the field bus node and
transmits the pulses further to the valves.
The operating voltage connection and a
decoder are situated on the valve sensor coup-
ling unit of the valve sensor terminal. The
decoder decodes the signals received from the
field bus node and transmits the pulses further to
the valves. The electrical inputs for e.g. sensors
as well as two additional outputs are also avail-
able here.
The valves control the flow of air to the actua-
tors.
The valves are supplied with compressed air via
the common channels of the sub-base. The ex-
haust and pilot air from the valves are also venti-
lated via these channels.
The sub-base is connected to the common
cables of the pneumatic system via the pneu-
matic interfaces.
