Wiresharking IEC
Some basic filters for analysing wireshark logs in case of IEC protocols.
IEC60870-5-104
If you use some port other than 2404, then Wireshark will not automatically detect the correct protocol. In this case,
- select a IEC104 packet from the captured packets list,
- go to Analyse -> Decode as
- In the transport tab, select TCP : both ports and protocol 104apci
Dispaly packages with TCP length>0 (no ack messages)
tcp.len>0
IEC104 packages
104apci
IEC104 packages (without testframes, S-packets etc)
104asdu
Packets involving 192.168.0.111
ip.addr==192.168.0.111
TCP port 2404
tcp.port==2404
Information object address 401
104asdu.ioa == 401
Spontaneous events (COT==3)
104asdu.causetx == 3
Command messages (COT 6, 7, 10)
104asdu.causetx == 6 //Activation 104asdu.causetx == 7 //Confirmation 104asdu.causetx == 10 //Termination
Testframe messages
104apci.utype == 0x10 //Activation 104apci.utype == 0x20 //Confirmation
S-Type messages
104apci.type == 0x01
General Interrogation commands
104asdu.typeid == 100 //Global, Group1...Group16
104asdu.qoi == 20 //Global
104asdu.qoi == 21 //Group1
104asdu.qoi == 35 //Group15
Do not use Group 16 GI with Martem devices. This is reserved.
Clock syncronisation commands
104asdu.typeid == 103
Show IEC104 measurements with value "0"
IEC104asdu.normval == 0
IEC61850 and Wireshark basics
MMS: Manufacturing Message Specification GOOSE: Generic Object Oriented Substation Events
Filter IEC61850 packets
mms
Display packets involving TCP port 102
tcp.port==102
Display messages containing domain ID "VampRelay"
mms.domainId == "VampRelay"
Display messages containing item ID "VI1GGIO137$CO$SPCSO$Oper" (VI1 control command)
mms.itemId == "VI1GGIO137$CO$SPCSO$Oper"
Display messages containing control commands (Service request 5 = write)
mms.confirmedServiceRequest == 5
Dispaly packets containing message "success" (response to command message)
mms.Write_Response_item == 1
Wireshark capture side-by-side with console.log
Case study: GW6e connects with Vamp255 device over IEC61850. RTU initializes communication, sends GI, executes a SBO command and receives a report (spontaneous) about change of LN state.
