7SJ61/62/63 6MD63 - Modbus
C53000-L1840-C001-01
The input register block allows the Modbus master to read the values of
the the analog inputs of the SIPROTEC device (recorded measured
values).
Note
Depending on the device composition not all of the indicated analog
inputs (and corresponding Modbus registers) may be available in the
SIPROTEC device.
Ref. to chap. 5.3 for data type definition of measured values.
By selecting the standard mappings (standard mapping 1 to standard
mapping 3) the measured values can be scaled in accordance with the
operational values of the primary equipment.
For each measured value the table in chap. 6.5.2 shows in the column
"Scaling" the scaling values defined in standard mappings 1 to 3, e.g.
(for "IA ="):
1: 3276.7 A
2: 3276.7 A
3: 32.767 kA
Note
All conditions in the table below to the selected standard mapping must
be fulfilled so that the measured values are transferred correctly via
Modbus.
Dependent on the SIPROTEC device either parameter address 207 or
parameter address 208 is adjustably.
