Logic
The optional logic function (extra code 260 "Math/Logic") supports formulas which can be freely used for
logical operations (binary values).
The results are available in the digital selector. If the function is not active, the logical value = 0.
Activating the function
On the device, the Logic function is only available when activated. To do so, the extra code "Math/Logic"
must first be activated in the setup program using an activation code (Setup program: Online parameters
> Enabling of extra codes).
The Logic function is available in the setup program after enabling the "Math/Logic" option (Configura-
tion: Basic device > Math/Logic).
