C.1.9 Rising Edge Coil (LEOC)
When used in a Ladder Diagram, this block acts as a coil that momentarily sets an
associated Bit tag to 1 when the rung state changes from 0 to 1.
Select the tool (from the Relays and Coils toolbar) and click on a ladder rung
to insert the following block:
Once the block is inserted, you can double-click on it to configure it.
Functional Description
This block always passes the input state through to the output state without
change; when the input state becomes on, the output state is turned on, and
when the input state becomes off, the output state is turned off.
When the input state from the left transitions from 0 to 1, the associated Bit tag
is momentarily set to 1. The tag is only maintained for a single execution of the
block, after which it is reset to 0.
Configuration Reference
Any Memory Bit (%MX) or Output Bit (%QX) tag may be associated with the
block.
