The field bus creates data communication be-
tween the controller and the field bus slaves
(e.g. valve terminal/valve sensor terminal) dis-
tributed throughout the system. Data trans-
mission is made in accordance with standard RS
485. Baud rates up to 1500 kBaud can be set.
The valve terminal as a decentral output mo-
dule processes the signals transmitted and con-
trols the actuators which are connected. The
valve terminal is supplied with current via an ex-
ternal power unit (AC 230V/DC 24V).
The valve sensor terminal as a decentral
input/output module functions like a valve termi-
nal. It also processes up to 30 inputs.
The air controlled by the valve terminal/valve
sensor terminal moves the
actuators or is used
for other tasks.
The sensors record information (measured vari-
ables) from the control process and pass this on
to the valve sensor terminal (further process-
ing unit).
