2.2.7.35 Registers 5001 to 5099: Latest 10 Dips (Read Only)
These registers are write-protected. A write attempt will be rejected with exception code 02
(ILLEGAL_DATA_ADDRESS).
Data type: Measured value + Date/time
The following table shows the information for the latest dip (5001 to 5009). The information of the other 9 dips
(5011 to 5099) are in the same structure.
