Basic Infeed open-loop control

Description
The Basic Line Module can be controlled via the BICO interconnection by means of
terminals or the field bus. The operating status is indicated on the operating display r0002.
The missing enable signals for operation (r0002 = 00) are mapped in parameter r0046. The
EP terminals (enable pulses) must be connected in accordance with the Equipment Manual.
Acknowledge error
Errors that are still present but the causes of which have been rectified can be
acknowledged by means of a 0/1 edge at the "Acknowledge error" (p2103) signal.
