16.6 Communication Test<br />
Using the parameter "510.08 TstClstCom" a communication test between the clusters can be started<br />
from each master device of a cluster. Switch only one master device of the extension cluster to<br />
"Transmit".<br />
The parameter "510.09 ClstComStt" delivers the status of the test. Query this parameter at all master<br />
devices, including the transmitting device. If the communication test is successful, the status "OK"<br />
appears.<br />
