Log Retrieval Window Block:

The Log Retrieval Window block is used to program the data you want to retrieve from

the log. It also provides the interface used to retrieve that data.

Registers: 0xC351 - 0xC3CD

Size: 125 registers

• Window Status: The status of the current window. Since the time to prepare a win-

dow may exceed an acceptable modbus delay (1 second), this acts as a state flag,

signifying when the window is ready for retrieval. When this value indicates that

the window is not ready, the data in the window should be ignored. Window Status

is Read-only, any writes are ignored.

0 Window is Ready

0xFF Window is Not Ready

• Record Number: The record number of the first record in the data window. Setting

this value controls which records will be available in the data window.

• When the log is engaged, the first (oldest) record is "latched." This means that

record number 0 will always point to the oldest record at the time of latching,

until the log is disengaged (unlocked).

• To retrieve the entire log using auto-increment, set this value to 0, and retrieve

the window repeatedly, until all records have been retrieved.
