Application
Automation system
The CP 343-1 ERPC communications processor is designed for operation in a SIMATIC
S7-300 automation system. It allows connection of the S7-300 to Industrial Ethernet.
Ethernet interface
To allow connection to Ethernet, the CP also has an interface complying with the gigabit
standard IEEE 802.3ab. The Ethernet interface supports autocrossing, autonegotiation and
autosensing.
ERPC functions
The ERPC functions allow communication by the CP 343-1 ERPC via LAN to an ERP
subscriber, for example, an ERP system or an MES. The ERPC application that runs on the
CP 343-1 ERPC handles the communication between the S7 station at the automation level
and ERP system at the enterprise management level.
You will find the requirements for this communication in section Procedure for using the
ERPC functions (Page 40).
