The IO-Link communications protocol consists of communication ports, communication modes, data types, and transmission speeds. The ports are physically located on the master, and provide it a means for connecting with terminal devices and for bridging to a fieldbus or Ethernet.
The ASi-5 system is open for the use of parameter interfaces such as e.g. IO-Link. IO-Link devices can be efficiently collected over long distances and could be integrated cyclically up to 32 bytes. 16 safe bits are available for safety-related switching devices, such as emergency stop, light curtains, safety switches and similar are available.
The CXL transaction layer is composed of three dynamically multiplexed (they change according to demand) sub-protocols on a single link: [36] [37] [24] CXL.io – based on PCIe 5.0 (and PCIe 6.0 after CXL 3.0) with a few enhancements, it provides configuration, link initialization and management, device discovery and enumeration, interrupts ...
HostLink Protocol, Omron's protocol for communication over serial links. Interbus, Phoenix Contact's protocol for communication over serial links, now part of PROFINET IO; MECHATROLINK – open protocol originally developed by Yaskawa, supported by the MMA; MelsecNet, and MelsecNet II, /B, and /H, supported by Mitsubishi Electric. Modbus PEMEX ...
Profinet implements the interfacing to peripherals. [1] [2] It defines the communication with field connected peripheral devices.Its basis is a cascading real-time concept. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosi
DeviceNet is a network protocol used in the automation industry to interconnect control devices for data exchange. It utilizes the Common Industrial Protocol over a Controller Area Network media layer and defines an application layer to cover a range of device profiles.
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.
Modbus standard also defines Modbus over Serial Line, a protocol over the data link layer of the OSI model for the Modbus application layer protocol to be communicated over a serial bus. [19] Modbus Serial Line protocol is a master-slave protocol which supports one master and multiple slaves in the serial bus. [20]
