High Level Data Link Control (Link Layer Data transmission protocol)
Accreditations
The Data Model defines data formats, types and dependencies and tells ProtoCrawler everything it needs to know to understand the content and format of the messaging over the communications interface.
The State Model captures information about how the target interface moves between different states based on the messages that are sent and received. Whilst some protocols are stateless, others have important restrictions and constraints according to the state that has been reached. Specific testing needs can be defined, such as higher coverage of messages that are processed before the sender has been authenticated.
The Application Context contains contextual data used to execute a protocol, e.g., identifiers and keys required to complete a cryptographic handshake. When defining tests using the application context, it is frequently useful to define abstract goals. This can significantly simplify the specification of some types of tests and allows the developer to focus test resources on more interesting areas.

Companion specification for Energy Metering
Zigbee Cluster Library revision 6
ZigBee is widely used to create personal area networks using low power digital radios, to enable wireless home automation.
IoT protocol used for low power wireless mesh communications. This standard defines the PHY and MAC layers.
Used (globally) for smart metering data exchange. Developed and maintained by the DLMS User Association (and also referred to as IEC 62056), the standard defines a set of interface classes or COSEM objects (Blue book) and supporting protocols (Green book).
Note: some parts of the world have different metering standards which use aspects/variants of DLMS (e.g. GBCS (UK), G3 PRIME etc.)
A well known standard/naming system for anything that connects to the internet or a private network.
Allows text-based domain names to be translated to numerical IP addresses. The protocol itself handles the data structures/exchanges as part of the wider IP suite.
Sets up a security association in IPsec and uses X.509 public key certificates for authentication.
Commonly used to connect electronic devices (e.g. RTUs/PLCs) with (e.g.) a master controller in an industrial control system.
Uses serial, ethernet or IP as a transport layer depending on the application.

Used to time synchronize all participating computers to within a few milliseconds of UTC. Sends and receives timestamps using UDP.
Used to automatically assign IP addresses to devices that want to be connected to an IP network.
Users a client/server arrangement (client uses DHCP to request information from the server). This is the IPv6 variant of the protocol.
Used to automatically assign IP addresses to devices that want to be connected to an IP network.
Users a client/server arrangement (client uses DHCP to request information from the server). This is the IPv4 variant of the protocol.
OASIS standard network protocol used to transport messages between devices (typically runs over TCP/IP) – also referred to as ISO20922.
NXP variant of IEC14443 Type A smart card standard including AES, DES and triple DES encryption standards.

The Open Charge Point Interface protocol (OCPI) supports connections between e-Mobility Service Providers and Electric Vehicle Charge Point Operators who manage charge stations to enable automated roaming between charge point networks.
Open Automated Demand Response (OpenADR) is an information exchange model and global Smart Grid standard which provides a non-proprietary, open standardised Demand Response interface allowing electricity network operators to communicate Demand Response signals to end customers.
The Open Smart Charging Protocol (OSCP) is an open communication protocol between a Charge Point Management System managed by a Charge Point Operator, and an energy management system operated by a Distribution Network Operator for the purposes of capacity forecasting. OSCP is partly based on OCPP messaging.
ISO 15118 is an international standard that defines a two-way, high-level communication protocol between Electric Vehicles and Charge Point stations aimed at promoting plug and charge interoperability between vendors. The protocol supports bi-directional communications to facilitate both grid-to-vehicle and vehicle-to-grid information exchange.

Definitions and transmission protocols for proximity cards (otherwise known as tokens), typically used for verifying ID and controlling access.
NXP variant of IEC14443 Type A smart card standard including AES, DES and triple DES encryption standards.
Developed by IEC TC57. Used for telecontrol/teleprotection applications (SCADA), mainly within the Utilities space.
Facilitates data transmission between two permanently connected circuits and enables interoperability between different suppliers.
Typically used for SCADA applications, mainly in the utilities sector. Facilitates communication between control centres, remote terminal units (RTUs) and IEDs.
Widely deployed in digital substations. Part of the IEC 61850 standard, used to transfer real time process data and supervisory control information between networked devices or computer applications.
Defines a set of standard objects, messages and encoding rules.
Widely deployed in digital substations. Part of the IEC61850 standard, used to group data formats into data sets and therefore facilitate fast data transmission (less then 4 milliseconds).
