Recipe names
By linking TEXT blocks to the ProgNo input, display of recipe names rather than of recipe numbers is possible.
This procedure can be used for both internal and external recipe selection. With external recipe selection, the required
recipe number must be applied to the index input of the TEXT block next to the APROG block (block 102 in this exam-
ple). This recipe number is fed to the ProgNo input of the programmer. With internal recipe selection (via operation or
level 1 interface data), the index input of the text block need not be connected.
Operation preparation and end position
Each program starts at an initial position
Wp0, which is used and maintained with reset or first programmer set-up.
With program start from rest position, the first programmer segment runs from the instantaneous process value at the
time of start command („ramp“ with gradient (Wp1 - Wp0) / Tp1). With step change mode, the of the first segment is
activated immediately.
At program end, either
w
0= Stop: the of the last segment is maintained (
r see below ),
w
1=reset:or the programmer goes to rest position
Wp0 (r see below ) and restarts automatically, if run is still va-
lid.
