The manual restart is activated using the "Manual" checkbox on the right near the 'Restart' button. The
'Restart' button can only be selected, if the manual restart is activated.
The characteristics of the input pair are configured with the setting buttons on the right near the two
MonIn or Secure inputs of an input pair. The 'MonIn(x)' and 'Secure(x)' buttons can only be selected if the
corresponding input has been activated via the Settings button. In the default state all inputs are disabled.
The corresponding feedback loop is activated using the 'Activated' checkbox on the right near the
'EDM(x)' buttons. The 'EDM(x)' button can only be selected, if the associated feedback loop is activated.
The FB MON input variables are linked using the 'Restart', 'MonIn(x)', 'Secure(x)' and 'EDM(x)' buttons.
The manual function test is activated using the 'Manual Function Test' checkbox.
The FB MON output variables are linked using the 'Error', 'MonOut' and 'MonDelOut' buttons.
The delay time of the 'MonDelOut' output is configured via the selection box 'Delay-Time'.
The characteristics for acknowledging a discrepancy error can be set via the checkbox 'Safe Inputs after
Disc Error'. If the checkbox is checked, both inputs of the input group that has caused the discrepancy
error have to switch to safe state simultaneously before the error can be reset.
The 'MapState' and 'MapDiag' checkboxes are used to specify which FB diagnostic functions are mapped
to the cyclic process image.
