Generating External Action Block Interface Routines

External action block interface routines are generated individually and separately from the load module that contains the action diagram for the external action block. This is done so that the interface routines can be completed before the rest of the code is generated and installed.

External action block interface routines can also be generated when the code for a load module or selected load module components is generated.

If you selected local installation, you can generate code for procedure steps and action blocks that use external action blocks, but you will not be able to successfully install that code until the external action blocks are completed and installed.
