5.161 L_TbCompare_n - scaled comparison
This function block compares two scaled signals and can be used e.g. for implementing a trigger.
• The comparison function is selected via C04080.
• In contrast to the FB
L_TbCompare , the window and hysteresis of this FB can be adjusted via pa-
rameters instead of inputs.
