User-Defined Function (UDF)
LOGO!Soft Comfort V7.0 provides you with a new option for creating circuit programs - the
UDF (User-Defined Function) editor. You can save circuit programs created in the UDF
editor as individual UDF blocks for use in a circuit program in the UDF or FBD editor.
A UDF block is a preconfigured circuit program that you create. You can add it to an existing
circuit program as you do with a function block. If the circuit program in LOGO!Soft Comfort
already contains a UDF, after transferring the program from LOGO!Soft Comfort to a LOGO!
0BA7, you can edit the elements connected to this UDF from the module.
For a detailed description of the UDF configuration in LOGO!Soft Comfort, refer to the online
help for LOGO!Soft Comfort V7.0.
Editing elements connected to a UDF block
You can neither create a UDF block from LOGO! 0BA7, nor edit the members of the block.
You can only edit elements connected to the inputs or outputs of a UDF block or edit its
parameter settings.
Note
Each UDF block has a maximum of eight inputs and four outputs, dependent upon your
configuration in LOGO!Soft Comfort. On the LOGO! module, only one input and one output
are active at a time.
