"Autozoom" softkey<br />
The "Autozoom" softkey only appears when a block that is being monitored is too long and does<br />
not fit on the screen.<br />
Pressing this softkey automatically adjusts the displayed blocks to the width of the screen. This way,<br />
the CNC shows the whole block without having to scroll it with the keys.<br />
After having pressed the "Autozoom" softkey, if the blocks are too small, the CNC will not show the<br />
data of the elements. Also, if autozoom has been activated, it is not possible to scroll up and down<br />
toward blocks that are not displayed on the screen.<br />
"Finish" softkey<br />
It may be used to exit the PLC monitoring screen in ladder diagram.<br />
Elements of the PLC program<br />
As mentioned earlier, the instructions of the PLC program in ladder language is made up of elements<br />
connected to each other by segments. These elements may be the following:<br />
i<br />
Normally open contact:<br />
The normally open contact is always displayed in the consultations area. Consults the logic state<br />
of a signal and, depending on the result, lets the flow pass or not.<br />
Normally closed contact:<br />
The normally closed contact is always displayed in the consultations area. Consults the logic<br />
state of a signal and, depending on the result, lets the flow pass or not.<br />
Relay coil:<br />
All the elements may appear in the PLC program in ladder language joined together<br />
in serial or in parallel.<br />
Comments are not displayed when monitoring the PLC program in ladder language.<br />
I10<br />
If I10 = 0, the contact is inactive and the flow does not pass.<br />
If I10 = 1, the contact is active and the flow passes.<br />
M100<br />
If M100 = 0, the contact is active and the flow passes.<br />
If M100 = 1, the contact is inactive and the flow does not pass.<br />
The relay coil is always displayed in the actions area. It activates or deactivates depending on<br />
whether it receives the flow or not.<br />
O1<br />
If the flow reaches the relay coil, it will be active and its value will be O1 = 1.<br />
If the flow does not reach the relay coil, it will be inactive and its value will be O1 = 0.
