PROFINET project modules
NOTICE
Overwriting of data by PLC!
Ä During the configuration phase, the DCR 248i receives data telegrams from the IO controller
(master). Before the data telegrams are evaluated and the respective settings are made, all
interface-specific settings are reset to default values. This ensures that the settings of mod-
ules that are not selected are set to the default values.
NOTICE
Ä You can find the default values of the DCR 248i in the module descriptions.
Ä Examples for using the modules: see chapter 18.5 "Communication examples".
NOTICE
Behavior of the input/output data
Ä The default value of the input data bits after switching on the device corresponds to the
specified initial value (generally ZERO).
Ä The outputs are deactivated during device start-up.
Ä For output data with status IOPS = Bad, the downstream functions are switched to a safe
state. This is the case, for example, if the control is switched to the STOP mode. For exam-
ple, an activated device or an output is then deactivated.
In the event of a connection interruption, the device behaves in the same way.
