Loading the individual PLC channels first<br />
As with the contactors, the PLC Manager also enables you to load the inputs and outputs<br />
(side elements) before the PLC main module is loaded. The PLC Manager manages a<br />
virtual PLC main module (a 'map' of the PLC inputs and outputs).<br />
First load a digital PLC output with the 'Symbol Explorer' and place it on the<br />
coordinates 235.0 / 110.0 mm with a single mouse click. This opens the database<br />
selection window. Select the extension module 'Digital Output SM 322-1BH00<br />
16x24V DC' and confirm with 'OK'.<br />
Now enter the function text '!Table control' and position it where ever you like. Abort<br />
the 'Symbol Parameters' menu and assign the current connection to channel 'A0.0'.<br />
Enter as PLC-Text 'Motor Worm on' and exit the 'Symbol Explorer'.<br />
Hint<br />

Obviously we would not need an Input and an Output module for<br />
our small example. This serves only to demonstrate the functions<br />
of the PLC manager.<br />
You may have realized that there is no cross-reference at this time. However, as we have<br />
not yet loaded the PLC main module, cross-referencing is not yet possible.<br />
Now we have to load two digital outputs for the control of the valves -Q1 and –Q2. Place<br />
them on the coordinates 95.0 / 110.0 mm and 130.0 / 110.0 mm but at this time<br />
with a double click with the left mouse button.<br />
This allows you to skip the database selection dialog (which is not needed here) and to<br />
make the channel allocation directly. (If you do accidentally activate the database,<br />
simply exit it and this will take you to the assignment menu). Assign the outputs for –Q1<br />
or –Q2 to the digital output 'Digital Output SM 322-1BH00 16x24V DC' (Function<br />
text: '!Table control'). Enter the PLC text for both valves -Q1 and -Q2 as: 'Table up'<br />
and 'Table down’.<br />
Tip<br />
A double click when loading the PLC main module takes you directly<br />
to the assignment of this symbol to a PLC module the PLC manager<br />
is already controlling. The rule is: every selection in the database<br />
menu creates a new PLC module in the 'PLC selection', so whenever<br />
you double click or quit out of the database selection window, the<br />
assignment menu will always appear. You can still delete any<br />
symbol with the 'Delete' command.<br />
The database dialog is not necessary because we have already set the parameters by<br />
inserting the individual PLC connection. Now you only need to assign the symbol to a<br />
PLC module controlled by the 'PLC selection'. Main modules which have not yet been<br />
assigned are marked with a '*'. These are 'virtual' PLC modules.<br />
Position the Output Unit<br />
Now go back to page 3 and load the symbol 'Digital Output SM 322-1BH00 16x24V<br />
DC' from the library 'EXAMPLE'. Position the symbol with a double click at 195.0 /<br />
147.5 mm. The 'PLC selection' dialog opens up again.
