* Schweitzer Engineering Labs ( " SEL " ) manufactures and sells digital protective relay equipment
2015-02-02 17:09:58 +00:00
* for use in industrial high - voltage installations . SEL Protocol evolved over time as a
2013-07-06 00:01:59 +00:00
* ( 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 .
*
2015-02-02 17:09:58 +00:00
* ' 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
2013-07-06 00:01:59 +00:00
* SEL Application Guides AG95 - 10 _20091109 . pdf and AG_200214 . pdf

* Dissector Notes :
*
2015-02-02 17:09:58 +00:00
* 1 ) All SEL Protocol messages over TCP are normally tunneled via a Telnet connection . As Telnet
2013-07-06 00:01:59 +00:00
* 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
*
2015-02-02 17:09:58 +00:00
* 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
2013-07-06 00:01:59 +00:00
* " 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 .
