General remarks
The product is intended for the operation of system CPX-E in a PROFIBUS DP network according to IEC 61158.
Data transmission takes place using an RS485 interface. Using an optical adapter, data transmission through
afibre-optic cable is also possible.
In a PROFIBUS DP network, the product acts as a DP slave and can be combined with up to 31 additional
participants. The process image is assigned by the user using the identifier byte during the planning and design
phase of the DP slave.
For the parameterisation of system CPX-E, the parameterisation data can be sent by the DP master to the bus
module using PROFIBUS DP. Using the DPV1 command, all data and parameters provided by system CPX-E can be
accessed. Through the USB interface, all relevant information of system CPX-E can be read and changed depending
on the function.
