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.
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. |
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. |
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. |
