At a Glance

The piloting objects are enabled by clicking on the mouse (or via the keyboard). Depending on the fixed attribute, these objects act on their associated variables.

NOTE: The state of associated variables can be changed by the PLC application. The action of the driven object doesn't constitute a forcing of the variable.

Furthermore, so long as the input of a value has not been validated or that the driven object maintains control, the displayed value may differ from the real value of the variable contained in the PLC memory.

How the buttons operate

Depending on its attributes, a button works as follows.

When you click on the button, if the associated variable is...

and if

Then

a bit,

driving is unsynchronized,

the associated variable switches to 1 when the left mouse button is held down, and switches back to 0 when released.

digital,

driving is unsynchronized,

the associated variable takes the fixed threshold value in the button attributes.

a bit,

driving is synchronized,

the state of the associated variable changes. It moves to 0 if it was at 1, and vice versa.

How a check box operates

A check box works as follows.

When the box

Then

is checked,

the associated bit is set to 1.

isn’t checked,

the associated bit is set to 0.

How an input zone operates

An input zone works as follows.

When

and if

Then

the entry zone contains a value,

you press Enter,

the associated variable takes the value read in the entry zone.

the associated variable is modified by the PLC,

you did not enter a value in the entry zone,

the zone displays the value read in the PLC.

How a counter operates

A counter operates as follows.

When

and if

Then

the counter is horizontal,

you click on the right arrow of the counter,

the associated variable is incremented by one unit.

the counter is horizontal,

you click on the left arrow of the counter,

the associated variable is decreased by one unit.

the counter is vertical,

you click on the top arrow of the counter,

the associated variable is incremented by one unit.

the counter is vertical,

you click on the bottom arrow of the counter,

the associated variable is decreased by one unit.

NOTE: The increment and decrement value is multiplied by 10, 100 then 1000 when the arrow is held down.

How a cursor operates

A cursor operates as follows.

When the cursor

and if

Then

is horizontal,

it is moved to the right,

the associated variable is incremented proportionally to the move made and to the minimum and maximum thresholds defined for the variable.

is horizontal,

it is moved to the left,

the associated variable is decremented proportionally to the move made and to the minimum and maximum thresholds defined for the variable.

is vertical,

it is moved upwards,

the associated variable is incremented proportionally to the move made and to the minimum and maximum thresholds defined for the variable.

is vertical,

it is moved downwards,

the associated variable is decremented proportionally to the move made and to the minimum and maximum thresholds defined for the variable.

How an inter-screen browser button operates

An inter-screen browser button operates as follows.

When the button

Then

is enabled by a click,

the screen with the associated number is displayed.

NOTE: In the case of Multi-Instance mode, clicking on the browser button opens a new window with the specified screen. If this is not the case, the new screen opens in the current window.

How an explicit exchange button operates

An explicit exchange button operates as follows.

When the button

Then

is enabled by a click,

the associated explicit exchange is launched. The memory zone of the PLC and that of the module are updated according to the configured parameters.
