Reset Function fault
Fig. 50: Timing diagram for reset function fault
OUT ENABLE is not reset if a critical systems fault is present. Examples are memory fault, power
failure, or voltage too low. Critical faults cannot be reset via the process channel. It is necessary to
eliminate the cause of the fault.
Note
The measured timing periods were determined with 12 Mbit- Profibus.
These timing periods can vary with different transmission rates and bus
systems. The cycle time of the PLC has not been taken into account.
1)
In case of “Function fault“ = 1 “Function result“ will sometimes remain at 0.

Parameter channel
The parameter channel is designed to exchange systems and parameter data of the R1000 with
the master. Primary purpose is the central data backup on the master. In addition, certain
measurement and operating parameters can be extracted from the R1000 and analysed by the
master.
Note
The configuration of the data format has to be compatible with the
PLC for consistent data transmission !
The data transmission via the parameter channel must be initiated with the service “Open
parameter channel“. The end of data transmission mission via the parameter channel must be
completed with the service “Close parameter channel“.
If the parameter channel is open then it is not possible to issue control commands via the process
channel or via inputs on the keyboard.
