Length

50 Byte IN, 2 Byte OUT 50 2
(50E2A)
6 Byte IN, 6 Byte OUT 6 6
(6E6A)
The planned output and input addresses are
important when using the example project on
the utility diskette. In the example project
(enquiry of FB 220) the two addresses must
be transferred as enquiry parameters (see
also "s7_doku.pdf“ on the utility diskette).
After the Profibus-Slave VEGASCAN has
been planned and the PLC loaded, the bus
error LED on the Profibus-Master must extin-
guish and the green "BA“-LED on
VEGASCAN must light permanently. If this
occurs, the Profibus communication between
PLC and VEGASCAN is functioning.
Example projects on the utility diskette
An example program for the operating mode
50E2A and an example program for the oper-
ating mode 6E6A is available on the utility
diskette for reading measured values out of
VEGASCAN. Further information on configu-
ration and function are included in the PDF
file "s7-doku.pdf“. To view the file, the
"Akrobat Reader“ is required. Please contact
VEGA Grieshaber KG if you need further
example programs or assistance.
