Content	Startup 7.2 Startup Characteristics of the CP 340 PtP coupling and configuration of CP 340 7-2 Manual, 04/2005, A5E00369892-01 7.2 Startup Characteristics of the CP 340 Introduction The CP 340 start-up is divided into two phases: • Initialization (CP 340 in POWER ON mode) • Parameterization Initialization As soon as the CP 340 is connected to the power supply, the serial interface is supplied with default parameters (the interface parameters are given preset values at the factory) of the module. As soon as the initialization is complete, the CP 340 automatically starts up with the 3964R driver with block check by default. The CP 340 is now ready for operation. Parameterization During parameterization the CP 340 receives the module parameters assigned to the current slot, which were generated using CP 340: Point-to-Point Communication, Parameter Assignment. Reparameterization is performed. The default parameters are overwritten with the new module parameters. 7.3 Behavior of the CP 340 on Operating Mode Transitions of the CPU Introduction Once the CP 340 has been started up, all data is exchanged between the CPU and the CP 340 by means of the function blocks. CPU-STOP In CPU-STOP mode, communication via the S7 backplane bus is not possible. Any active CP-CPU data transmission, including both send and receive message frames, is aborted and the connection is reestablished. Data traffic at the RS 232C interface of the CP 340-RS 232C is continued with the ASCII driver and the printer driver in the case of parameterization without flow control. In other words, the current send request is completed. In the case of the ASCII driver, receive message frames continue to be received until the receive buffer is full.
