Keylock switch
You can use the keyswitch to set various access rights. The keyswitch
has four settings for protection levels 4 to 7.
Machine data can be programmed to interlock access to programs,
data, and functions at various protection levels.
Please also refer to the machine manufacturer's instructions.
The keyswitch has three keys of different colors that you can remove
in the specified positions:
Position 0
No key
Protection level 7
Position 1
Key 1 black
Protection level 6
Position 2
Key 1 green
Protection level 5
Position 3
Key 1 red
Protection level 4
When you change the key position to change the access
authorization, this is immediately not visible on the operator interface.
You have to initiate an action first (e.g. close or open a directory).
If the PLC is in the Stop state (LED of the machine control panel is
flashing), ShopTurn does not evaluate the keyswitch positions during
boot up.
The machine manufacturer can set up protection levels 0 to 3 using a
password. When the password is set, ShopTurn does not evaluate the
keyswitch position.
