FIPIO Configuration
Confirming the configuration
Introduction
Confirmation refused
On completion of the FIPIO bus configuration, and in order to be recognized in the new application, the global bus configuration must be confirmed.
The PL7 then checks the constraints associated with this new application. If the imposed constraints are not respected, no scanning table is created.
A message window opens in this case.

How to access the recommendations
The configuration remains unconfirmed (Bus X physical configuration and FIPIO physical configuration) as long as the problem is not corrected by the user. This configuration can not be transferred into the PLC.
The Recommendations button enlarges the dialogue box where the reasons for refusal as well as useful corrective measures are located.

Recommendation>>
Periodic Mast task in controlled mode
Period: 100 ms
Network cycle time: 177 ms
The network cycle time is greater than the period.
To correct this you can:
- configure this task period at a value greater than 177ms
- reduce the number of devices configured in this task.
- switch this task to free mode
If a task’s constraints are not respected, the cause of the failure and corrective recommendations complete the characteristics.
Depending on the recommendations, there are two possible measures for correcting the configuration, these are as follows: l Access the configuration screen of the processor to modify the PL7 task management parameters.
l Access the FIPIO configuration screen to modify device distribution in the MAST or FAST tasks.
