************************************************************************************************
|
|
* Schweitzer Engineering Labs ("SEL") manufactures and sells digital protective relay equipment
|
|
* for use in industrial high-voltage installations. SEL Protocol evolved over time as a
|
|
* (semi)proprietary method for auto-configuration of connected SEL devices for retrieval of
|
|
* analog and digital status data. The protocol itself supports embedded binary messages
|
|
* (which are what this dissector looks for) slip-streamed in the data stream with normal
|
|
* ASCII text data. A combination of both are used for full auto-configuration of devices,
|
|
* but a wealth of information can be extracted from the binary messages alone.
|
|
*
|
|
* 'SEL Protocol' encompasses several message types, including
|
|
* - Fast Meter
|
|
* - Fast Operate
|
|
* - Fast SER
|
|
* - Fast Message
|
|
*
|
|
* Documentation on Fast Meter and Fast Message standards available from www.selinc.com in
|
|
* SEL Application Guides AG95-10_20091109.pdf and AG_200214.pdf
|
|
************************************************************************************************
|
|
* Dissector Notes:
|
|
*
|
|
* 1) All SEL Protocol messages over TCP are normally tunneled via a Telnet connection. As Telnet
|
|
* has special handling for the 0xFF character ("IAC"), normally a pair of 0xFF's are inserted
|
|
* to represent an actual payload byte of 0xFF. A function from the packet-telnet.c dissector has
|
|
* been borrowed to automatically pre-process any Ethernet-based packet and remove these 'extra'
|
|
* 0xFF bytes. Wireshark Notes on Telnet 0xFF doubling are discussed here:
|
|
* http://www.wireshark.org/lists/wireshark-bugs/201204/msg00198.html
|
|
*
|
|
* 2) The auto-configuration process for Fast Meter will exchange several "configuration" messages
|
|
* that describe various data regions (METER, DEMAND, PEAK, etc) that will later have corresponding
|
|
* "data" messages. This dissector code will currently save and accurately retrieve the 3 sets
|
|
* of these exchanges:
|
|
* 0xA5C1, 0xA5D1, "METER" region
|
|
* 0xA5C2, 0xA5D2, "DEMAND" region
|
|
* 0xA5C3, 0xA5D3, "PEAK" region
|
|
* The configuration messages are stored in structs that are managed using the wmem library and
|
|
* the Wireshark conversation functionality.
