Cost advantage resulting from connection to two separate Ethernet segments with network separation
High level of plant availability due to support of media redundancy (MRP)
Optimum support of maintenance due to
Web-based diagnostics
Remote programming via WAN or telephone network
Monitoring with IT network management tools (SNMP)
Module replacement without programming device using the C-PLUG swap medium
Securing the system1) against unauthorized access by means of
Central access protection for any devices within an automation cell, e.g. by reliable authentication of the network nodes
Secure remote access via the Internet by means of data encryption (VPN) and data integrity checking
Traceability by means of data logging on the basis of standard IT mechanisms (Syslog)
The ability to connect existing SIMATIC S7 systems to Industrial Ethernet at a later point in time using the CP 343-1 Advanced ensures investment protection
1) Security functions, firewall and VPN only with -1GX31 variant
