SE_XCBR_CTL
Circuit-breaker control and interlock (IEC 61850 XCBR/CSWI shaped) with a protection trip seal-in, aux-contact position decoding, pulsed coil outputs, trip-circuit supervision and latched breaker-failure supervision.
When to use it
Use SE_XCBR_CTL when operator and protection requests have to be turned into a breaker command in the PLC, with the interlocks, the trip seal-in and the did-it-actually-move supervision that a switchgear controller is expected to have.
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
SE_XCBR_CTL 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 SE_XCBR_CTL — 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.
