About Working with Dimensions
When you use the Profile Editor application to assign dimensions (force,
displacement, and so forth) to the end levels in a profile, you should be aware
that they must map to the dimensions of the control modes included in the station
configuration on which you wish to play out the profile.
Because of this, it is good practice to be aware of all of the instances in which
dimension selections affect your ability to play out profiles, such as:
• You use the Profile Editor application to create command files (profiles) by
typing the end-level values you desire the actuator to achieve during the
course of the profile. To make end-level values meaningful, you must
specify dimension and unit types (for example, displacement and
centimeters).
• You use the MPT application to play out profiles you create with the Profile
Editor application. When you open the MPT application against a station
configuration, it inherits the resources of the station, which include the
control mode dimensions selected for the control modes in the station, as
defined with the Station Builder application.
• You use the MPT Profile Command process to import profiles, and to map
the logical channels in your profile (referred to as profile channels) to the
physical channels in your station configuration.
Note The MPT application does not require the names of profile channels to
be the same as the names of station channels. You can arbitrarily map
any profile channel to any station channel. You can also map one profile
channel to multiple station channels.
• You also use the Profile Command process to select the control mode of a
profile channel. For this to work (if the dimension used to define the end
levels of the profile is a standard engineering dimension, such as force or
length), the dimension must match one of the control mode dimensions
available to the current station configuration.
Example
Suppose you use the Station Builder application to create a station configuration
with one channel that uses the force dimension for a force control mode, and the
length dimension for a displacement control mode.
In addition, you use the Profile Editor application to create a profile in which you
select the length dimension to define end levels for a channel you named
Channel 1.
To play out the profile file you created, open the Station Manager application and
select a configuration file containing the appropriate resources for your test.
