Santerno Sinus Penta - Exchanged Parameters

PROGRAMMING GUIDE
SINUS PENTA
433/486
52.3. Exchanged Parameters
The tables below state the Sinus Penta parameters exchanged via Fieldbus.
Each table contains:
1) the parameter code;
2) its description;
3) its range;
4) its unit of measure (also indicated on the display);
5) the ratio between the Sinus Penta value (exchanged via Fieldbus) and the represented hardware value (as
displayed).
NOTE Each parameter is exchanged as an integer value with 16-bit sign (-32768 to +32767).
NOTE
Bytes are exchanged in big-endian mode (the most significant value is stored to the
smallest memory address).
When using an Intel based master/PLC chipset, then the data below will be byte-swapped.
NOTE
The PLC must enter all the exchange variables, with no exception. If required, it is
possible to suppress all the variables in sequence after suppressing the variable desired.
For example, if all data are required from the Master to the Slave up to “Commands for
digital outputs from Fieldbus”, the first six variables shall be entered by the PLC. Variables
from 7 on may not be entered to the PLC.
