Press ESC to exit the circuit diagram and parameter display.
4.1.2.1 Opening the parameter display for function relays with contacts or coils
If you specify the contact or coil of a function relay in Entry mode, easy
automatically switches from the contact number to the function relay
parameter display when you press
OK .
Press í to switch to the next contact or coil field without entering any
parameters.
4.1.2.2 Program
A program is a sequence of commands which easy executes cyclically in
RUN mode. An easy program consists of the necessary settings for the
device, password, system settings, a circuit diagram and/or function relays.
4.1.2.3 Circuit Diagram
The circuit diagram is that part of the program where the contacts are
connected together. In RUN mode a coil is switched on and off in accordance
with the current flow and the coil function specified.
4.1.2.4 Function Relays
Function relays are program elements with special functions. Example:
timing relays, time switches, counters. Function relays are elements
provided with or without contacts and coils as required. In RUN mode the
function relays are processed according to the circuit diagram and the results
are updated accordingly.
• Examples:
Timing relay = function relay with contacts and coils
Time switch = function relay with contacts
4.1.2.5 Relay
Relays are switching devices which are electronically simulated in easy. They
actuate their contacts according to their designated function. A relay consists
of at least one coil and contact.

easy performs many of these cursor movements automatically.
For example, easy switches the cursor to Move mode if no
further entries or connections are possible at the selected
cursor position.
