timer is initiated on these reads. Should the timer run out (the index is not incremented/read in 30
seconds), the appropriate log will be allowed to continue logging.
When a value of 0x0FFFF is written to this register, this signifies that the port is finished accessing
the appropriate log, and the 30-second timer is canceled and the appropriate log will be allowed to
continue logging.
Should multiple ports access the same log simultaneously, the log will be paused while either 30-
second timer is running; the log will be allowed to continue logging only when both ports time-out
or write 0x0FFFF to their index register.
Auto Increment Log Window- 64 registers, 128 bytes.
These registers are a 128-byte window into a log, as specified in the Auto Increment Configuration
(register 39423, 0x099FE). Depending on the Auto Increment Window Index, a different 128-byte
area of a log can be accessed.
See section 5.1.4: Downloading Logs with Auto Index and Modbus Extensionsfor the usage of
these registers.
