● CP 343-1 Advanced with security function: Security of the system against unauthorized
access by
– Central access protection for any device within an automation cell, for example, by
secure authentication of the network nodes
– Secure remote access via Internet thanks to data encryption (VPN)
– Data integrity check
– Traceability with data logging based on standard IT mechanisms (Syslog)
● SIPLUS CP 343-1 Advanced
The SIPLUS CP 343-1 Advanced module is intended for environmental loads at ambient
temperatures of 0 °C to +60 °C.
CP 343-1 ERPC (Enterprise Connect)
The CP 343-1 ERPC communications processor (Enterprise Connect) is designed to
connect a SIMATIC S7-300 system to Industrial Ethernet networks.
The CP supports the following:
● PG/OP communication
● S7 communication
● Open communication (SEND/ RECEIVE)
● ERPC communication
● Direct interfacing with database applications such as ORACLE, MySQL, MS-SQL, DB2.
This allows controllers to be supplied with data or jobs directly from databases of
manufacturing execution systems (MES) or the enterprise resource planning level (ERP).
Note
Database connection of the SIMATIC S7
-300 to various database systems for vertical
integration is supported by a firmware expansion from the ILS
-Technology company that
must be ordered separately.
● A C-PLUG for storing the configuration data ships with the product.
● Optimum support of maintenance with:
– Web-based diagnostics
– Remote programming via LAN/WAN
– Monitoring using the network management tool (SNMP)
– Module replacement without PG using the C-PLUG exchangeable medium
● Access protection with a configurable IP-ACL (IP Access Control List)
The CP 343-1 ERPC communications processor allows subsequent connection to existing
SIMATIC S7 systems within Industrial Ethernet.
