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):
The Master Can composes and manages the single bits as appropriate.
Monitor Bit0 lift decomp
Monitor Bit1 lift decomp
Monitor Bit14 lift decomp
Monitor Bit15 lift decomp
