• An additional interface is implemented to enable the tape to be operated in conjunction
with the data distributor and the operator panel:
Interface DB 144
15
DW 6
Ready signals
The operator panel FBs working with the data distributor indicate that they are available by
setting bits 0 to 7 (positive or negative acknowledgement to data distributor, DB 146/ D1.1 and
D 1.2). The data distributor checks DR 6 for the value 255.
At present, only three FBs (FB 190, FB 191 and FB 192) work with the data distributor in this
manner. 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 in FB 161 is set to zero. If necessary, the function
blocks of the operator panel then restore their initial settings!
FB 192 must also be called conditionally in the initial setting (F 2.1)
to be able to restore its initial setting and set bits
D 6.2, D 6.3, D 6.4, D 6.5, D 6.6 and D 6.7 in DB 144.
