Operation

The cursor buttons in the EZ circuit diagram perform three

functions. The current mode is indicated by the appearance of

the flashing cursor.

•Move

• Enter

• Connect

In Move mode you can use

ÍÚ úí to move the cursor around

the circuit diagram in order to select a rung, contact or relay

coil.

change a value at the current cursor position. If you press

ESC in Entry mode, EZ will undo the most recent changes.

relays. Press ALT again to return to Move.

Opening the parameter display for function relays with

contacts or coils

If you specify the contact or coil of a function relay in Entry

the function relay parameter display when you press OK.

Press

í to switch to the next contact or coil field without

entering any parameters.

Program

A program is a sequence of commands which EZ executes

cyclically in RUN mode. An EZ program consists of the

necessary settings for the device, password, system settings,

a circuit diagram and/or function relays.

EZ performs many of these cursor movements

automatically. For example, EZ switches the cursor to Move

mode if no further entries or connections are possible at the

selected cursor position.
