Loading via tape
Description
This function block enables FB 155 "Tape" internally via its status word (D2.8 in DB 135).
FB 155 "Tape" of the tool management must be enabled (D2.8 in DB 135) via the operator
panel (FB 190) to be able to execute after an NC start. The evaluation of this enable signal can
be selected and deselected in FB 155 "Tape" depending on an input parameter.
Special feature: An additional interface is implemented to enable the tape to be operated in
conjunction with the data distributor and the operator panel:

Ready signals:
The operator panel FBs indicate that they are available for cooperation with the data distributor
by setting bits 0 to 7 (positive or negative acknowledgement to data distributor, DB 146/D1.1
and D1.2). The data distributor checks DR 6 for the value 255.
At present, only three FBs (FB 190, FB 191 and FB 192) cooperate with the data distributor in
this way. Thus one of these FBs (FB 192) must set six bits while the other two FBs (FB 190,
FB 191) set one bit each. These three function blocks set ready flags in the initial setting
(F 2.1).
On initial setting (F 2.1), DB 144, DR 6 of FB 161 is set to zero; if necessary, the function
blocks of the operator panel then restore their initial settings.
FB 190 must be called conditionally in the initial setting (F 2.1) to be able
to restore its initial setting and set bit D 6.0 in DB 144.
