Note! You should not configure the respective input and output areas bigger then what really needed. The
reason for this is that all bytes you set up here will be transferred over the fieldbus, regardless if
they are used by the application or not.
If you want to transfer Process data over the fieldbus then you must create a Fieldbus -Reporter. How to
do this, and connect it to your fieldbus device, is described in the New reporter chapter. How to make the
Reporter format the result as you wish is described in chapter: Edit reporter.
Indication of the fieldbus status
When connected to a target system you can study the current status of the module using the
