Addressing of the switching conditions
when connected to DISBUS If you imagine the 16 register bits belonging
to a VEGAMET as one 16 bit word, the
following graphical repesentation results.
The meaning of the individual bits is defined
as follows:
Status of inputs:
0 =
all inputs OK
1 = input status not available (no inputs
configured or VEGAMET not available)
Switching status of inputs 1 and 2:
0 =
input contact is open
1 = input contact is closed
Status of outputs:
0 =
all outputs OK
1 = output status not available (no outputs
configured or VEGAMET not available)
Switching status of outputs 1, 2 and 3 (output
3 corresponds to fail safe relay):
0 =
relay is deenergised
1 = relay is energised
Note:
A complete overview of the process images
on the switching status of VEGACOM 558
can be found in supplement B at the end of
this operating instructions manual.
