Addressing of the output status when
connected to LOGBUS
The image of the output status when con-
nected to VEGALOG is always sorted acc. to
the module numbers of the output cards. The
following demonstration shows the address-
ing of the intermediate storage via Modbus.
Imagining the 16 register bits belonging to a
module cards as a 16 bit word, the following
regulation results.
The meaning of the individual bits is defined
as follows:
Status of the output card:
0 = OK
1 = no values of the output card available
(no outputs configured or card not
available)
Switching status of the outputs on AR or AT
cards:
0 = relay deenergised
1 = relay energised
Note:
A complete overview of the process image of
the switching status of VEGACOM 557 can
be found in supplement B at the end of this
manual.
