Motion apps

The functions of the Motion Terminal are defined by what are known as Motion apps. A Motion app generally
executes a pneumatic task such as pressure regulation, flow control or the controlled acceleration and braking of
a movement.
Motion App #01 "Directional control valve functions", which is part of the basic equipment of the Motion Terminal,
is described in this document (è 2.5 Motion App #01: Directional control valve functions).
Additional Motion apps are each described in separate documentation (è www.festo.com/sp).
2.3.1

Motion app ID

Each Motion app has a unique ID. This ID is required both to select and to parameterise the Motion app.
The respective ID is given in the Motion app documentation.
2.3.2

Licences

To be able to use a Motion app, a corresponding licence must be stored on the Motion Terminal controller. For many
Motion apps, the number of licences required for each app is based on the desired number of valves on which the
Motion app should run simultaneously.
Motion App #01 "Directional control valve functions" is licensed as standard for all valves on the Motion Terminal.
It is therefore possible, for example, to run a different directional control valve function on each of the maximum
8 valves of a Motion Terminal.
Additional Motion apps can either be run simultaneously on all valves of the Motion Terminal with just one licence,
or can be run on the same number of valves as there are licences for the Motion app stored on the Motion Terminal
controller.
If, for example, Motion App #03 "Proportional pressure regulation" is to be run on 3 valves at the same time, there
must be 3 licences stored for this app.
The number of licences stored on the Motion Terminal and the number that are free (not in use by an
active Motion app) can be viewed on the WebConfig interface.
The licences are not assigned to a particular valve position. Each licensed Motion app can be run on any valve.
The restrictions relating to the number of licences only apply in respect of running a Motion app simultaneously on
multiple valves.
Information on adding to your available licences can be found in the Festo catalogue
(è www.festo.com/catalogue).
2.3.3

System and application parameters

The basic conditions for operating a Motion app are set using system and app-specific parameters. There is a
distinction here between 2 types of parameters:
– System parameters describe the components that are connected to the Motion Terminal (tubes, drive, mounting
position, etc.). System parameters apply to a valve position and hence jointly to all Motion apps running on this
valve position.
– Application parameters describe the application of the Motion app (moving mass, travel time, minimum force,
etc.). Application parameters can be stored separately on each valve for each Motion app.
The following sections relate to transferring the system and application parameters using the
higher-order controller (PLC). Since communication only allows for integer values, the unit-based values
are increased by a factor to give integer values.
Example:
The tube internal diameter can be defined in 0.01 mm steps in the range from 0 ... 100 mm. To do this,
a value in the range 0 ... 10000 is transferred. One increment (digit) therefore corresponds to 0.01 mm.
