4.5.12 Searching for contacts and coils
Boolean operands or function blocks that are wired as contacts or coils can
be found in the following way:
▶
Press ESC. Use the cursor buttons ÍÚ to enter the SEARCH menu.
▶
Press OK.
▶
Use the cursor buttons Ú and ú í to select a contact or coil as well as the
required number.
For a function block you select the function block name and the number.
▶
Confirm the search with the OK pushbutton.
The search starts from where the search was called and is continued to the
end of the circuit diagram. It applies only to this area. If the required contact
or coil is located above the point of calling, start the search at the beginning
of the circuit diagram. If the search is successful, you will automatically reach
the required contact or coil field in the circuit diagram.
4.5.13 Switching with the Cursor Buttons
With an easy800 device, you can also use the four cursor buttons as hard-
wired inputs in the circuit diagram.
The P buttons can also be used for testing circuits or manual mode. These
button functions are also useful for servicing and commissioning purposes.
The cursor buttons are wired in the circuit diagram as contacts P 01 to P 04 .
Requirement :
The P buttons have been activated in the System menu
