5 Project planning
7. Configure the station name/device name and IP address of the PROFINET device. Also configure
the communication parameters.
NOTE!
Engineering systems offer a function for identifying field devices. If JUMO field devices are addressed
via the "Identification function" of the engineering system, this is signaled by the flashing of the front
display.
The communication parameters set here (Send clock, Reduction ratio, etc.) are merely examples.
Station name:
To improve the overview in the IO controller project structure, each device should be assigned a self-
explanatory and unique station name. This permits a better overview for programming and project
planning. The station name is entered in the engineering system of your IO controller at the PNIO
identification data of the JUMO IO device.
IP configuration:
The engineering system requires a valid IP configuration for the Ethernet interface of the JUMO IO
device. The device will not connect to the IO controller without a valid IP configuration for the Ether-
net interface.
NOTE!
The JUMO IO device is still accessible using the JUMO setup program or a web browser via Ethernet.
The IP address of the Ethernet interface must be used for communication.
Cyclical transfer timing:
Send clock and reduction ratio determine the frequency at which an IO device transfers cyclical data
in a PROFINET IO network. The transfer cycle time of the JUMO IO device is calculated by dividing
the send clock by the reduction ratio. On JUMO field devices, these parameters apply globally for all
slots. The setting is configured in the engineering system of your IO controller at the PNIO parame-
ters of the JUMO IO device.
