Applications of the fast inputs/outputs
Fast inputs
In the PLC application program, you can directly read each bit value from the address
DB2900.DBX0.0
.
In a part program, you can read each bit value from the address DB2900.DBX0.0 via corresponding system variable.
Fast outputs
From the address
DB2900.DBX4.0
you cannot assign a value to the fast output; otherwise, the PLC application program will
stop with an error. However, you can assign a value to the fast output from address
DB2800.DBX5.0
and
DB2800.DBX6.0
.
In the PLC application program, you can trigger the address
DB2800.DBX5.0
with a rising edge or a negative edge at the
address
DB2800.DBX6.0
, and thus the address
DB2900.DBX4.0
will vary with the address
DB2800.DBX6.0
.
For example, if you want to use
I0.0
to trigger or deactivate the set/reset of the address
DB2900.DBX4.0
, you can write as
follows in the PLC application program:
In a part program, you can set or reset the fast output via its corresponding variable. The system variable is
$A_OUT[1]
.
For example:
23.7
Creating user cycles
The control system is integrated with standard Siemens cycles. If necessary, you can also create your own cycles.
To create a customized cycle, you must prepare the files shown below:
User cycle file
User cycle alarm file
User cycle bitmap file
Extended user text file
User cycle softkey index file
User cycle parameter file
23.7.1
Creating the extended user text file
The extended user text file is required for the display of respective screen texts, cycle messages and softkey texts.
