4.3 Commissioning the Festo field bus
4.3.1 Configuration
The field bus configurator in the FST software will help you in
creating the NOMINAL configuration. The menu control and
operation of the FST software is described in the appropriate
FST manual for your controller.
Configure your system as follows:
Enter the field bus address of the field bus slave (valve
terminal).
Enter the string number (only FPC 405).
Select and enter the type of the valve terminal from the
field bus type file (valve terminal 03" for types 03/04−B).
Enter the calculated inputs/outputs byte−by−byte under
IW and OW. The number of IWs may differ from the
number of OWs.
Please note
The entry mask of the field bus configurator shows the IWs
and OWs on the screen. This stands for input words and
output words, therefore 16 bits each. If you select a type
03 valve terminal from the type file, the software will in
terpret all I/O entries as bytes, therefore 8 bits each. Opti
mum byte−by−byte configuration of the modular valve ter
minal is therefore possible.
Example
48 inputs
⇒
6 IW (48 bits)
20 outputs
⇒
3 OW (24 bits)
