BUSWAY_TAP_MON
Busway tap-off box monitoring: loading against the tap rating, joint temperature rise over ambient and rate of rise.
When to use it
Use BUSWAY_TAP_MON when racks are fed from overhead busway through plug-in tap-off boxes whose bolted or clamped joint is the highest-risk connection in the white space, and that joint is instrumented for temperature.

Download BUSWAY_TAP_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.
