Discrepancy time monitoring for the two input groups is activated via the “Discrepancy” checkbox. The
discrepancy time can be set in the selection box next to the checkbox.
The characteristics of the input pair are configured with the setting buttons on the right near the two
TwoHand(x) inputs of an input pair. The 'TwoHand(x)' buttons can only be selected when the associated
input has been activated. All inputs are deactivated in the default state.
The FB TWO-HAND input variables are linked using the 'TwoHand(x)' buttons.
The buttons ‘Error’ and ‘TwoHandOut’ are used to link the output variables of FB Two-hand.
The ‘MapState’ and ‘MapDiag’ checkboxes are used to specify which FB diagnostic functions are mapped
to the cyclic process image.
