4.3 Button functions

4.3.1 Identical parameter

4.3.1.1 Lock object

The lock object can be activated for grouped buttons as well as for single buttons. If the lock object is
active, a communication object is displayed for the respective button or button pair. Depending on the
device type, up to 8 lock objects can be activated.
If the disable object is assigned a logical "1", the corresponding button is "locked" and can therefore no
longer be switched. A "0" cancels the lock.
The following table shows the associated communication objects:
Number Name / Object function
9 T1: – Lock object
Table 8: Identical communication object – Lock object

A text field is available for each button or button pair for free labelling:

functions and with the communication objects of the functions:
