The PLC network status provides status information about the link modules, the links, the transfer and the loops.
Link unit status
The numbers 1 to 63 represent the link modules. The input status of each link module in the network is indicated in the right column. Four question marks (????) indicate that the link module with the module number indicated on the left does not exist. U stands for link module, B for serial port module. The values are updated in accordance with the current set polling rate.
Route status
Indicates the network status (Good/Bad).
Transfer status
Indicates the frequency of the respective error.
If the communication station is the Home unit, the value 255 will be displayed in the field No response.
If Good is displayed for the net status, the value is influenced in the transfer and link status only by installing/removing fiberglass cables and by the On/Off status of the link modules. A change in the value might be due to a disconnected link, break in the cable or a link module failure.
