INTRUSION_MON
Four-zone intrusion monitor with exit and entry delays, first-up zone capture and an always-live tamper loop.
When to use it
Use INTRUSION_MON when a plant room, meet-me room, cage or perimeter is protected by supervised door contacts and motion detectors that have to be armed out of hours, with one authorised entry route the operator uses to reach the keypad.

Download INTRUSION_MON — 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.
