摘要
Methods and architectures are described that provide function block mobility between PLCs. Each PLC configured with Mobile Function Blocks (MFBs) may forward and execute MFBs from each other. To enable MFB mobility over a communication bus, each PLC having one or more configured MFBs requires a Communication Function Block (CFB) and an MFB directory data block. Each PLC maintains an MFB directory data block to store its MFB directory which is used when other PLCs send requests to check the availability of MFBs they need to run new tasks.
