Publisher
The diagnostic variables VarState and FrameState are available in the publisher. Detailed properties for the transmission of an EAP telegram are clarified by means of these diagnostic variables.
VarState
VarState (size: 16 bits) provides information about the current state of the TxData.
The following values are possible for VarState:
|

Bit |
Description |
|---|---|---|
|
Not Sent (variable skipped) |
VS.0 |
The TxProcessData is transmitted as long as the value is 0. The transmission of the TxProcessData is otherwise suspended. |
 | EL6601/EL6614 This variable is not created when using the EL66xx terminals. |
FrameState
FrameState (size: 16 bits) provides information about the current state of the TxFrame. The following values are possible for the FrameState:
|
Short description |
Bit |
Description |
|---|---|---|
|
Not Sent (frame skipped) |
FS.0 |
The Ethernet frame is transmitted as long as the value is 0. The transmission of the frame is otherwise suspended. |
|
Error (frame oversized) |
FS.1 |
If the value is 1, the maximum size of an Ethernet frame has been exceeded. The linked variable should be smaller. |
|
Subscriber Missing (Unicast only) |
FS.2 |
This bit is only set if the Subscriber Monitoring is activated (see chapter Publisher Box). The value is set as soon as the Subscriber Monitoring mechanism detects that the EAP device to which the Ethernet frame is sent is no longer reachable. The bit is reset to 0 as soon as the reachability is restored. |
| EL6601/EL6614 This variable is not created when using the EL66xx terminals. |
