OCPP_SESSION
OCPP 1.6/2.0.1 charging-session state machine with metered transaction energy and smart-charging profile enforcement.
When to use it
Use OCPP_SESSION when a charge point has to authorise a presented identifier, open and close a metered transaction, and enforce the power ceiling a central system or local load manager sends down as a ChargingProfile.
Interface

Download OCPP_SESSION — free
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, 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.
