This means that the BICO interconnections for the terminal wiring are set in such a way
that all enables and responses communicate correctly.
If the option is not activated (check box is not selected), then changes have been made
in the BICO interconnection in relation to the standard interconnection. If these changes
were not intended you can use the "Set standard terminal wiring set" option to restore
the SINUMERIK compliant interconnection.
Enable this option in order to set the standard terminal wiring. This means that the
configuration is interconnected in compliance with SINUMERIK.
