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 parameterization interface.
Reparameterization is performed. The default parameters are overwritten by the newly set
module parameters.
