If switch 1 is set to position "ON“, the meas-
ured values will be grouped acc. to DCS
indices or channels.
The following illustrations show in detail the
possible memory mappings for the storage
of measured values when connecting VEGA-
COM 557 to DISBUS.
Note:
When addressing register words, all ad-
dresses between 0 and 65 535 can be used
for VEGACOM 557. For access to the inter-
mediate storage, VEGACOM 557 generally
uses only the last 3 digits of the address.
