↓UDF: List of user-defined function blocks configured in the circuit program
● L: A Data Log function block configured in the circuit program
List contents
All lists show the elements available in LOGO!. Usually, this includes all connectors, basic
functions, and special functions. The ↓BN and ↓UDF lists show all the blocks that you have
created in LOGO!.
If not all is shown
LOGO! does not show all elements if:
● No further blocks may be added.
This is either an indication of insufficient memory space or that the maximum number of
blocks has been reached.
● A specific block's memory space requirement (Page 130) would exceed the space
available in LOGO!
● You have not previously configured them (network digital and analog inputs/outputs, UDF
blocks, and the Data Log block) in the circuit program in LOGO!Soft Comfort and
downloaded the program to LOGO!.
