A detailed diagnosis of the AS-i bus is also possible by using an external unit,the eASi tester . This unit is optimised for the needs of service, commission-ing and maintenance staff. It is connected to the bus cable in parallel without stopping production. The supplied software enables assessment of the quality of the data messages of all connected slaves on a connected PC or notebook. The ratio between all messages and the number of repeat mes- sages is shown clearly. When industrial inverters are earthed for example, success can be checked when thebus system is running.
