Structuring Mode Fcon (Connect Functions, Connection) - Siemens SIPART DR22 Manual

3.3.8 Structuring mode FCon (connect functions, connection)

3.3.8 Structuring mode FCon (connect functions, connection)
In the FCon mode (only appears when S4 = 1) the functions defined with YES in the FdEF mode
are connected (software „connected") with each other and with the selectable inputs and outputs
(FE1 to FE12) of the freely connectable range. A connection is made by setting a data source/data
sink pair on the digital x and y display. The data sink (question) is always set first followed by the
data source (answer). The connection is established when switching to the next data sink or retur-
ning to the structuring preselection mode FCon.
The data sinks (inputs of the functions and the outputs of the freely connectable range) and the data
sources (outputs of the functions and inputs of the freely connectable range) are stored in the listed
order. The data sources and sinks of the functions defined by no are hidden.
Every data sink can only be assigned exactly one data source whereas every source can be con-
nected with as many sinks as you like. The parallel loop of inputs (sinks) is therefore achieved by
connection of the respective inputs with the same output (source). The presettings of the inputs
(ncon or numeric values) specified in the description of the various functions is transferred to the
FCon mode and can be changed (overwritten) there if necessary.
Changes in the FdEF, if FCon has already been carried out
If functions defined by YES are overwritten by no after connection in the FdEF mode, the existing
connection to the inputs and outputs of the functions overwritten by no is removed. The inputs (data
sinks) fed by the output of the deleted function are identified by ncon (not connected).
Error message ncon Err
It is not permissible to end the connection with data sinks defined by ncon because the desired func-
tions cannot run with undefined inputs.
If the structuring preselection level is to be left with the Exit key and some data sinks (inputs) are
still defined by ncon, the flashing error message ncon Err appears and the structuring preselection
level is not exited, the error can be corrected (Enter key) or ignored (Exit key).
The error message is acknowledged by pressing the Enter key. It returns to the configuring mode
FCon to the first data sink marked ncon, the error can be corrected.
