9.10 Topology - Configuration
By configuring the topology you specify for the PROFINET IO controller the physical con-
nections between the stations in your PROFINET IO system These "neighbourhood rela-
tions" are used among others at "Device replacement without exchangeable medium".
Here by comparison of target and current topology, the IO device without a name is
detected and automatically integrated to the user data traffic. By configuring the topology
you have the following options:
n
You can evaluate topological errors in your application program
n
You have greater flexibility in planning and expansion of a plant
Support Topology editor is limited
Please consider that the support for the topology editor of the Siemens
SIMATIC Manager is limited. Here you have only the possibility to con-
figure the target topology offline. An online matching is currently not pos-
sible. An interconnection of the ports is also possible by means of the
port properties!
1.
Click in the hardware configurator at the according PROFINET port and open the
properties dialog via
‘Context menu
è
Object properties’
and select the register
‘Topology’
ð
The properties dialog to interconnect the ports is opened.
2.
Here you have the following parameters:
n
Port interconnection
–
Local port: Name of the local port
–
Medium: Specifying the line type (copper, fibre optic cable). Currently, this
parameter is not evaluated.
–
Cable name Specifying a cable name
n
Partners
–
Partner port: Name of the port to which the selected port is interconnected.
–
Alternating partner ports: By specifying at
‘Partner port’
"Any partner", you
can configure alternating partner ports for the I/O devices. Currently, this
parameter is not evaluated.
n
Cable data
–
Cable length: Depending on the port medium you can set in the select list
the cable length, if the medium between two stations does not change. Here
the signal delay time is automatically calculated. Currently, this parameter is
not evaluated.
–
Signal delay time: If the medium between two stations changes, a signal
delay time can be defined here. Currently, this parameter is not evaluated.
3.
Close the properties dialog with [OK] again.
