Parameterisation
The behaviour of the system CPX-E can be parameterised with the aid of suitable software from Festo or using
ahigher-order controller. Here, a distinction is made between the following variants:
–
System parameters
–
Module parameters (module-specific and channel-specific)
–
Parameterisation of the diagnostic memory
A detailed description of the individual parameters can be found in “Description of system CPX-E” and
inthe descriptions of the individual modules

3.1
Access to system CPX-E via DPV1
By means of a higher-order controller, parameter and status information, as well as the system data of system
CPX-E, can be accessed by DPV1 commands.
The DPV1 command is available only if the bus module is configured with the following option:
“CPX-E-PB:DP-Slav e [DP-V1]”
3.1.1
Data records
The parameters and data are accessed by a slot number and an index number.
The slot number for module-related data is as follows:
–
Slot number = module 100
The index number can be found in Tab. 3.1 … Tab. 3.4.
The following tables show the connection between the access to parameters and data with DPV1 and function
numbers.
Additional information the function numbers can be found in “Description of system CPX”
