6.5 Example of Control Word Composition
A signal can generally be connected to a normal or expanded digital input, some internal signals and a bit of
the Lift Decomp word bit. With the EPC application, two Decomp word bits are used:
•
Control word 1 is the input of decomp lift word bit 1
•
Control word 2 is the input of decomp lift word bit 2
Selection of the origin (source) of the word to be used for "
Decomp word
" block decoding. Each bit that is
part of the word to be decoded is associated with an ‘output channel of the "
Decomp work
" block. The
variables that can be used for this function can be selected from among those listed in the “
L_WDECOMP
”
selection list.
This control word in the example is connected to a PDC process channel so that:
•
[1530[ Control Word 1 =
FieldBus M->S1
•
[1532] Control Word 2 =
FieldBus M->S2
In some specific cases control word 1 or 2 can be connected to the “WComp” drive parameter or to a
PAD
parameter
(PAD16).
In this example the single bits of the two control words have the following meaning:
CONTROL WORD1 (SelLiftWdecInp):
