6. Function blocks6.3 UF - User function blockProgramming viewFigure 211: Analog coil tabIf there are any user function blocks with bit and/or analog inputs available, you will beable to select the "User function block inputs" option in the "Type" drop-down menu.Meanwhile, the "Operand" drop-down menu will contain all registered user functionblocks that have bit and/or analog inputs.The "Number" drop-down menu will contain all available function block numbers withina range of 1 to 127, as well as the comment entered for the corresponding number.Please note that any instance numbers that have already been assigned to other typesof user function blocks will not be available for selection.Finally, the "Function block inputs" drop-down menu will list the various individualinputs, together with information specifying whether the coil is connected internally.In addition, you will be able to select the coil function (Contactor, Set, Reset, etc.) fordigital inputs.6.3.5.1 User function blocks in an ST main programA user function block created with the FBD language can also be called in an ST mainprogram and vice versa.In this case, a template based on the user function block's parameters (as defined inthe Interface section) will be generated in the ST program if the function block isdragged onto the program. You will be able to connect the inputs and outputs the sameway as with manufacturer function blocks.The NAME and VERSION you entered originally will be used to define the user functionblock's type and version. These two pseudo inputs cannot remain unconnected and arenot allowed to be mapped outside of the function block call.444 easyE4 11/18 MN050009 EN www.eaton.com
