3.5.3 Remote access
EMC supports efficient and secure access to building automation and control sys-
tems using e.g. DESIGO Web on the customer network.
EMC additionally allows for remote energy management in building automation and
control system. This function is based on a harmonized Siemens remote service
platform (common Remote Service Platform – cRSP), used in numerous other
Siemens areas.
This access allows for carrying out the following functions from a machine with In-
ternet connection, depending on the functionality of the building automation and
control system:
• Operation and monitoring (plant pictures)
• Display of trend profiles
• Alarm handling
Remote operation is available for all systems featuring a web interface (e.g. APO-
GEE GO, DESIGO web server, DESIGO PX Web). Bidirectional connection be-
tween EMC and the remote network is established via dynamic VPN (virtual private
network). Numerous measures guarantee a secure connection, e.g. encryption,
professional router management coupled with active supervision of all connections.
Remote access is logged via user name and time stamp (start/end of connection).
Remote access can be enabled or disabled for each user.
