Setup
Transmission of the data base to CP
Menu: Load –> CP data base transfer –> FD-CP
If the CP parameter setting is finished, the data base must be transferred to the communica-
tion processor:
- provide connection PC/programming device with CP5431
- stop CP with "Load –> CP Stop"
- transfer parameter data base to the CP: Load –> CP data base transfer –> FD-CP
- set CP to operating condition with "Load –> CP Start"
Important:
The new data base is only active after switching off the voltage supply of the CP (mains com-
ponent) and switching it on again.
4.4 S5 functional components for data exchange between AG and CP
To ensure the data exchange between the S5 application (AG) and the communication proc-
essor (CP), the AG is equipped with integrated functional components (FB). These are de-
scribed in detail in the Siemens automation manual and are only explained briefly here. With
this FB, orders are transferred to the CP and data received from the CP are collected.
A description of the necessary integrated functional components follows. Each FB requires an
interface and an order number as parameter which was determined with the CP parameter
setting (see: FMS planning).
