CP 343-1 ERPC
84 Manual, 03/2010, C79000-G8976-C239-02
CPU
Central Processing Unit
Main processor of a SIMATIC controller
ERP subscriber
Network subscriber that communicates with a SIMATIC S7 station with CP 343-1 ERPC. An
ERP subscriber can, for example, be an Enterprise Resource Planning (ERP) system at the
enterprise management level or an → MES.
ERPC
Enterprise Resource Planning Connect
Connection between the process level (SIMATIC S7) and the enterprise level (→ ERP
subscriber)
ERPC application
Software package of the cooperation partners ILS Technology LLC for communication
between an S7 station and → ERP subscribers. The ERPC software is also loaded on the
CP 343-1 ERPC. The ERPC software consists of the following two parts:
● The → ERPC firmware
This installs the ERPC application on the CP. The application handles → ERPC
communication.
● The → ILS Workbench configuration
This supplies the ERPC application with the required parameters for ERPC
communication.
ERPC communication
Communication between a SIMATIC S7 station with a CP 343-1 ERPC and an → ERP
subscriber. ERPC communication is handled using TCP/IP on Industrial Ethernet.
ERPC communication is possible using two methods, the → logical trigger and/or
spontaneous or cyclic read and write jobs.
Using read jobs, data is read from the CPU and sent to the ERP subscriber. With write jobs,
data is written by the ERP subscriber to the CPU.
ERPC communication is possible only when the ERPC software and the ERPC-specific
STEP 7 configuration is loaded on the CP.
See also → ERPC application.
ERPC firmware
Firmware part of the cooperation partners ILS Technology LLC for communication between
the CP 343-1 ERPC and an → ERP subscriber. To use the ERPC functions, the ERPC
firmware must be loaded on the CP 343-1 ERPC and activated in the → ILS Workbench.
