SE_79_AR
MiCOM / SEPAM shaped multi-shot auto-reclose (ANSI 79) with per-shot dead times, a check-sync gated pulsed close, a reclaim window and lockout on every failure path.
When to use it
Use SE_79_AR when an overhead feeder breaker is to be reclosed automatically after a protection trip — most overhead faults are transient — and the scheme's shot counting, dead times, reclaim window and lockout conditions have to be modelled and demonstrated.
Interface

Supervised control write
SE_79_AR 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.

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.
