Concept
The principle of configuration control is already known at the device level for the flexible use
of submodules/modules ("option handling"). Different configurations can be derived from
one engineering project both for central as well as for distributed I/O.
With S7-1500 CPUs as of firmware version V1.7, this principle can also be applied at the
IO system level. You have the option of omitting, adding or changing the order of stations
(IO devices) of a PROFINET IO system in a specific plant.
Configuration control for devices and configuration control for IO systems can be combined;
the functions are independent of each other.
It is possible to operate variants deviating from a maximum configuration of an IO system. In
a standard machine project, you can prepare a kit of IO devices which can be flexibly
customized for various configurations using configuration control.
The following variations are available:
•
Variation of the number of IO devices involved
You include optional IO devices for the configuration control in the configuration by
transferring a suitable data record with the required configuration in the user program.
• Variation of the order of IO devices involved
You adapt the port interconnection of the IO devices to the topology being used by
transferring a suitable data record with the required topology in the user program.
