Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
As an example, we will search for the standards for PROFIBUS-DP. This belongs to the CPF 3 family and has the profile CP 3/1. In Table 5 we find that its protocol scope is defined in IEC 61784 Part 1. It uses protocol type 3, so the documents IEC 61158-3-3, 61158-4-3, 61158-5-3 and 61158-6-3 are required for the protocol definitions.
MECHATROLINK – open protocol originally developed by Yaskawa, supported by the MMA; MelsecNet, and MelsecNet II, /B, and /H, supported by Mitsubishi Electric. Modbus PEMEX; Modbus Plus; Modbus RTU or ASCII or TCP; MPI – Multi Point Interface; OSGP – The Open Smart Grid Protocol, a widely use protocol for smart grid devices built on ISO ...
IEC 60870-5-104 (IEC 104) protocol is an extension of IEC 101 protocol with the changes in transport, network, link, and physical layer services to suit the complete network access. The standard uses an open TCP/IP interface to network to have connectivity to the LAN ( local area network ) and routers with different facility ( ISDN , X.25 ...
MIL-STD-1553B, which superseded the earlier 1975 specification MIL-STD-1553A, was published in 1978.The basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required.
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1]
Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Its main use is in utilities such as electric and water companies.
