Local Peer Tx (yellow) |
On - normal operations. The SISNet Repeater is receiving global data from other SISNet Repeaters and transmitting it to the Local peer bus. Flashing - normal operations. There is no Logic Solver for the SISNet Repeater to synchronize with on the Local peer bus. Note This normally occurs during early configuration when Logic Solvers are planned, but not yet installed. |
Flashing (Local peer Tx only) |
The SISNet Repeater is not receiving its own transmissions while still receiving the transmissions of local Logic Solvers. |
Contact technical support |
|
Flashing (both Local peer Tx and Rx) |
Local peer bus extender cables are disconnected, bus is not terminated or is terminated with wrong resistance. |
Check Local peer bus cables and termination. |
||
|
Off |
The SISNet Repeater Local peer bus transmitter hardware has detected a problem. |
Contact technical support |
||
|
Local Peer Rx (yellow) |
On - normal operations. The SISNet Repeater is receiving transmissions from local Logic Solvers. Off - normal operations. There is no Logic Solver for the SISNet Repeater to synchronize with on the Local peer bus. Note This normally occurs during early configuration when Logic Solvers are planned, but not yet installed. |
Flashing (both Local peer Rx and Tx) |
The Local peer bus extender cables are disconnected, bus is not terminated or is terminated with wrong resistance. |
Check Local peer bus cables and termination. |
|
More than 5% of received messages have errors. |
Check Local peer bus termination. Contact technical support |
|||
|
Off |
The SISNet Repeater Local peer bus receiver hardware has detected an error. |
Contact technical support |
||
|
Remote Peer Tx (yellow) |
On - normal operations. The SISNet Repeater is transmitting local and remote global messages on the fiber-optic ring. |
Flashing |
Break in fiber-optic ring. |
Check that this SISNet Repeater is receiving remote global data and its own global data is making it around the ring. |
|
Off |
Hardware error. |
Contact technical support. |
||
|
Remote Peer Rx (yellow) |
On - normal operation. This SISNet Repeater is receiving global data. |
Flashing |
Fiber-optic cable is disconnected, broken, or crossed. |
Check fiber-optic cable connections. Connections are: primary to primary, secondary to secondary. |
|
More than 5% of received messages have errors. |
Check remote peer predecessor for transmit error. Contact technical support. |
|||
|
Off |
Hardware error. |
Contact technical support. |
If a single SISNet Repeater is used (for example for diagnostic testing), loop the SISNet Repeater to itself input to output.
