Parameter assignment
Parameter assignment
Keep the following points in mind when assigning parameters for PROFIenergy:
●
Parameters for PROFIenergy are assigned with the parameter data record (version 2),
index 3. The interface module distributes the PROFIenergy parameters to the I/O
modules.
●
The parameter assignment of an additional pause behavior is possible immediately after
the start of the previous "Pause". The required state for the following pause is activated
with a new "Start_Pause" command.
●
You can write the parameter assignment as often as needed.
●
The interface module checks the distribution of the parameters to the I/O modules and
returns the result as a return value of the write job. In the case of a negative return value,
there are one or more I/O modules that have not accepted the parameter data record. In
this case, the I/O modules respond according to their last PROFIenergy parameter
assignment in case of an incoming "Start_Pause" command. "Start_Pause"/"End_Pause"
commands can be executed as planned with a positive return value.
●
In case of a failure of an I/O module or station outage, you must repeat the parameter
assignment using the parameter data record.
●
The ET 200AL distributed I/O system supports configuration of the behavior of a "pause".
If a different response is required for an additional "Pause", you will have to assign
parameters again.
Note
Effect: The response (switch-off) of the I/O modules to PROFIenergy is related to the slot,
which means all channels in the slot behave accordingly.
