7.3 Testing and optimization
Testing and Once you have installed, wired and parameterized the unit, you can test and
optimization optimize your FM 354 positioning module. Testing and optimization can be
information
performed with the aid of the testing and start–up interface with or without
the user program.
You can also test individual modes and their traversing programs, and view
and debug them during execution.
There are two ways of operating the FM:
This interface is installed with "Parameterize FM 354". Once the FM 354 has
been parameterized, you can call it up by selecting the menu Test Startup
or by selecting from the overview display.

You can monitor the interface between the FM and the user program. You
can also control the program from the start–up user interface when control
signal [TFB] (TEST_EN) is enabled in the user program. Example ap-
plication 3 (see Section 6.7) can be included in the user program for this
purpose.
