GOV_RL_OUT
Raise/lower contact driver for a motor-operated governor speed setpoint, with bounded pulse width, enforced off-time and a cumulative travel limit.
When to use it
Use GOV_RL_OUT when the speed setpoint of a packaged governor or engine controller is trimmed by a motor-operated potentiometer driven from two contacts, and a continuous speed bias has to be converted into pulses.

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.
