Siemens Simatic CFU, Commissioning Manual

Page: 194 / 220

This block concept supports all modules from the list of approved modules.
When new Siemens or non-Siemens module types are integrated, the meta-knowledge for the
driver generator can be extended by additional XML files (object and action lists).
Note
Driver and diagnostics blocks
● The library with the driver blocks has to be installed using the Setup program on the PC. This
is the only method of ensuring that the meta-knowledge required for the driver generator is
available. You must not copy the library from another computer.
● You can also use driver blocks from another library (for example, your own blocks from your
own library). You can specify this additional library in the "Generate module drivers" dialog
box. The driver generator then searches for the block to be imported in the library specified
here. If the block is not found here, it is searched for in the library specified in the control file
(XML file).
● If the S7 program contains a signal-processing block but not from one of the PCS 7 libraries,
you have to specify the version of the driver library from which the driver blocks are to be
imported in the "Generate module drivers" dialog box.
Time-optimized processing
For time-optimized processing of the user program during runtime, PCS 7 automatically carries
out the following programming tasks:
● Divide organization blocks for error handling (for example, OB 85, OB 86) into runtime
groups
● Installing driver blocks into the corresponding runtime groups
If an error occurs, the SUBNET block, for example, activates the relevant runtime group, the
RACK block or MODULE block contained in the runtime group detects the error, evaluates it
and outputs a process control message to the OS.
The diagnostics information of the MODULE block (OMODE_xx output) is also transferred to
the corresponding CHANNEL block (MODE input).
If necessary, this information can be displayed by means of a PCS 7 block that can be operated
and monitored on the OS or by means of a user block in a process picture (color change of the
measured value or flashing display, etc.).
