Issue:
Data is uploading on Main server but on localhost showing 'err' value
Reason:
1. Variable configuration at local is not correct
2. variable data is not coming in file
Steps to check:
1. check the start address of variable is not same as main server.
e.g. if start address of a variable at main server is 1032 then do not configure same at localhost (local server)
1.1. give start address '1' at localhost (local server)
1.2. for next variable give start address '2'
2. check file format in 'LocalDataExport' folder
