IMPORT_EXPORT_CTRL
Utility-tie import/export regulation at the intertie meter, with a no-export floor and export annunciation.
When to use it
Use IMPORT_EXPORT_CTRL when generation runs in parallel with the utility and the controlled quantity is the flow at the INTERTIE METER — a fixed import, a zero-export condition, or a contracted export — rather than the machine's own output.
Interface
The published port signature. This is the whole of what the block exposes to your program — the implementation body is not shown here and ships with the download.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format it ships, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
