Checking the circuit diagram

The logic relay contains a built-in measuring device enabling
you to monitor the switching states of contacts and relay
coils during operation.
Complete the small parallel connection and switch the
X
logic relay to RUN mode via the main menu.
Return to the circuit diagram display.
X
You are now unable to edit the circuit diagram.
h
If you switch to the circuit diagram display and are unable
to modify a circuit diagram, first check whether the logic
relay is in STOP mode.
The circuit diagram display performs two functions
depending on the mode:
• STOP: Creation of the circuit diagram
• RUN: Power flow display
Switch on I3.
X
In the power flow display, energized connections are thicker
than non-energized connections.
You can follow energized connections across all rungs by
scrolling the display up and down.
h The power flow display will not show signal fluctuations in
the millisecond range.This is due to the inherent delay
factor of LCD displays.
