CHARGE_DISPATCH
Signed power dispatch clamped to the live BMS envelope, tapered into the SOC limits and rate-limited.
When to use it
Use CHARGE_DISPATCH when any request for battery power — market, arbitrage, frequency response, peak shaving — has to be turned into a setpoint the PCS may actually be given, inside the charge and discharge limits the BMS is publishing at this instant.
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.

Supervised control write
CHARGE_DISPATCH commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.

Download CHARGE_DISPATCH — 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 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.
