OVEN_ZONE_CTRL
Tunnel-oven zone burner control with belt-derived bake time and latched over/under-bake deviation.
When to use it
Use OVEN_ZONE_CTRL when one temperature-controlled zone of a multi-zone tunnel oven modulates a burner to a zone setpoint, and the bake time delivered in that zone follows from the belt speed rather than from a timer.

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 it ships, 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.
