Dataloging in micrologix 1400 can be done from PLC and the stored data can be retrieved using datalog extraction utility. I am familiar of this. I need help with below mentioned points.

1. Program access to data log data (I believe its not possible as the memory used for data log is independent of memory for user program)
2. The manual has information for writing a custom application for datalog retrieval.Need some assistance from someone who has done it.

Thank you for your time.
