7.2 Startup Characteristics of the CP 341
CP 341b start-up
The CP 341 start-up is divided into two phases:
● Initialization (CP 341 in POWER ON mode)
● Parameter assignment
Initialization
As soon as the CP 341 is energized, all module components are initialized.
Parameter assignment
Parameter assignment means that the CP 341 receives the module parameters assigned to
the current slot as created with the CP 341: Point-to-Point Communication, Parameter
Assignment parameter assignment interface.
A parameter reassignment check is executed. The CP 341 is now ready to operate.
Startup behavior when power supply for the module is turned on
If the CP 341 has its own 24 V DC power supply independent of the CPU, communication
between the CPU and the CP 341 is interrupted if the 24 V DC power supply of the CP 341
fails.
To resume communication between the CPU and CP 341, proceed as follows for the CPUs
and devices listed below:
