Security On connection,each user supplies their id and password which is subsequently compared with the list of authorised users.
The security «call-back» serves as an additional protection.
All attempts to connect and successful connections are logged..
   
Tailored access

Depending on their identity each user has different access rights: The IP domain and the applications which are accessible is limited by the fire-wall.
Thus, for example, one user may only be allowed to consult the PLC’s web server and the web cams whereas another may have access to the maintenance programming.

   
Remote maintenance of the networked machines. The RAS-M156’s particular strong point is the remote maintenance of numerous machines connected on the same ethernet network: The programming of the central computer and that of the PLCs in the network is accessible securely, via a single telephone line as if you were there yourself.
   
Remote access to industrial web servers and web cams.
 The RAS-M516 server also permits remote access to the PLC’s web servers or the retransmission of a web cam.
   
Simple installation The RAS-M156 server is installed through an HTML navigator.
Remote configuration can be authorised by an on-site operator at the push of a button and subsequently be locked again in order to prevent breaches in security.
