TONR
Retentive on-delay timer — accumulates the time IN is TRUE across interruptions until RESET.
When to use it
Use TONR when a total accumulated time matters rather than a continuous one — cumulative run time before service, total time a limit has been exceeded.

Download TONR — 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.
