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.

C.1.10 Falling Edge Coil (TEOC)

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 1 to 0.
