I wanna ask if it's possible to get full access to tia portal (Edit OBs,FBs and Etc) via internet.

My company begun a work order from Turkey and my base is at Greece. The client doesn't have any programmer to change something to the program (Add an alarm for example or add a new quality control sensor or something) so he asked me if it's possible to get fully access over the Internet.

Tia Portal v13 

Cpu : 1215

Hello,

yes this is possible.
Keywords are Remote Access and VPN.
