Motion App #01: Directional control valve functions

Motion app ID
01
Tab. 2.44
The Motion app ID must be transferred using the "valve mode" section of the process data (bits 5 ... 0 in
byte 0 (PDO)) to run the Motion app on a valve (è 2.4.2.1 Structure of the output data (PDO)).
2.5.1

Functional description

The Motion app makes 9 directional control valve functions available for execution by the corresponding valve. The
directional control valve function makes it possible to assign the characteristics of a conventional switching valve to
a valve on the Motion Terminal. The integrated sensors enable monitoring of the switching position and of the
pressure at the working ports. If the pilot pressure or power supply are interrupted, the valve reverts to its
mechanical normal position (all channels are blocked).
The valve types listed in section è 2.5.5.1 can be allocated cyclically to the CPX terminal by means of the process
data. In addition, the switching status of the particular valve type can be specified cyclically using the process data
of the CPX terminal.
