How to configure a Logic Equation?
Call up menu [Logics/LE [x]]:
Set the Input Signals (where necessary, invert them).
If required, configure the timer (» On delay« and »Off delay«).
If the latched output signal is used assign a reset signal to the reset input.
Within the »status display«, the user can check the status of the logical inputs and outputs of the Logic Equation.
In case that Logic Equations should be cascaded the user has to be aware of timing delays (cycles) in case of
descending sequences (Please refer to section: Cascading Logical Outputs).
By means the Status Display [Operation/Status Display] the logical states can be verified.]
