I/O System S900
Communication Interface for PROFIBUS DP, CI920
column delivers the hexadecimal number for this subset. This number is the
higher order part of the byte to "construct".
The meaning of subset two, which corresponds to bits 0 to 3 of the data byte,
is module-specific. The procedure is the same as for subset one: Search the
line with all requested parameters and take the subset number of the first
column. Add this number as the lower order part to the byte to "construct".
Only the shown subset numbers are valid, all others are denied by the S900
on download. Then edit this byte in the corresponding field of the master
engineering tool.
Note that an empty slot also has one User_Parameter byte which must be set
to zero!
Commissioning the S900 with Composer/Melody
To commission the S900 on a Symphony / Melody system the DTM is
required. The DTM serves the I/O data mapping and the parameterization and
configuration of the station. All input values are processed with a status
information. Nevertheless the scaling of analog input values must be done
manually in the input and output function blocks in the Composer.
•
For 0..20 mA inputs use range 0 – 40000.0 (to get 0..100%), unipolar
•
For 4..20mA inputs use range 8000.0 – 40000.0 (to get 0..100%),
unipolar
•
For temperature inputs use range 0.0 – 20.0 (to get K), unipolar
•
For temperature inputs use range 5444.0 – 5484.0 (to get °C), bipolar
Commissioning the S900 with AC800M
S900 comes with alle required hardware definition files. First an empty
termination unit (S900) has to be configured below the PROFIBUS interface
of the Controller. The CIPB (CI920S) has to be configured on position 0
inside the S900 slave.
Diagnostics
Standard PROFIBUS diagnostics can not be processed by AC800M.
Nevertheless via the status supervision an input value can be detected as valid
