6. Function blocks6.3 UF - User function blockA user-function-block-specific plausibility check will not be run when copying and past-ing between user function blocks. All checks are identical to those run on the main pro-gram.Within the context of the plausibility check for a device, the system will check whetherthe total number of user function blocks per device is less than or equal to 127. If theplausibility check for a device outputs an error / warning for a user function block in the"Report output" dialog box and the view for the user function block is not active or openin the Programming view, double-clicking on the error / warning will activate, or, ifapplicable, open the Programming view for the user function block and show exactlywhere the error or warning is found.Depending on the corresponding results, the following messages may appear after aplausibility check:l FB input / FB output %2 is not part of the user function block's interfacel The number for an FB input / FB output was not assigned without gapsl FB input %2 exceeds the maximum number of a total of 12 bit and analog inputsl FB output %2 exceeds the maximum number of a total of 12 bit and analog outputsl Operand %2 is not supported in user function blocks!l The number for operand %2 falls outside the permissible value range for user func-tion blocks.6.3.8 Importing a user function blockThe import function makes it possible to load user function blocks (uf7 files) from afolder. This function is available in the Programming view.In order to be able to import user function blocks, all open userfunction blocks must be unmodified.If they are not, the following message will be output: If openuser function blocks are modified, an import will not be pos-sible. Please save all modified user function blocks first..Select a uf7 file and click on "Open"The selected user function block will be added to the user function block managementgroup only if it meets certain criteria.The following messages can occur:l User function block is already found in easySoft 7.You do not need to import it. Do you want to select a different file?l A user function block with different content is already found in easySoft 7. Since it isused in the project and the function block interfaces are different, the import is notallowed. Do you want to select a different file?easyE4 11/18 MN050009 EN www.eaton.com 449
