SIPROTEC Modbus - Bus mapping 7SJ80/7SK80/7RW80
C53000-L2240-A320-3
The Holding register block allows the Modbus master to read system and diagnostic
information, statistic values as well as to execute time synchronization of the
SIPROTEC device.
Holding registers are also used for reading the Event recorder entries ("Sequence of
Events").
Note:
Depending on the device composition, not all of the indicated statistic values (and
corresponding Modbus registers) may be available in the SIPROTEC device.
• Registers are write-protected.
