CAN fieldbus (Controller Area Network) was developed by Bosch® to connect the network of command devices, sensors and actuators in production lines of the car industry. The maximum length of the bus depends on the transmission speed rate and the selected conductor sizes: 20 metres for 1 Mbps / 100 metres for 500 kbps / 500 metres for 125 kbps / 1km for 50 kbps. MotionCables provide CAN BUS cables for application from static to high dynamic, with PVC or PUR outer sheath.

Developed by Allen Bradley, the DeviceNet specifications are now managed by the Open DeviceNet Vendor Association (ODVA) which includes a wide range of devices. DeviceNet is a two connection system based on CAN that works with a data transmission speed rate in the range between 125 and 500 kbps. The RS 485 standard is used as transmission protocol. The DeviceNet specification recommends two cable types: the first one for the execution of the back-bones (trunk/thick) and the second one for the derivation connections to the devices (drop/thin). Both are flexible cables composed of two individually shielded twisted pairs, dedicated respectively to data transportation and power supply to the devices. You can find it in PVC and PUR solutions.
PROFINET is an open and innovative standard for industrial Ethernet in automation applications. PROFINET is intended for process automation, manufacturing automation and real-time movement control solutions. It allows the integration of existing fieldbuses, such as PROFIBUS, INTERBUS, DeviceNet and other technologies, in an open network based on the Ethernet. PROFINET uses the Ethernet standard and TCP, UDP and IP protocols for the communication, configuration and diagnostics of the network. It easily integrates with Internet and ICT infrastructures. Fieldbus cables intended for PROFINET applications are supplied for CAT.5e performance levels. These cables are available either for fixed or mobile installations and are used in the industrial field and process automation to support applications such as Ethernet with a transmission speed rate of up to 100 Mbps.
|MotionBUS Industrial Ethernet|
The enormous success of the Ethernet technology in the industrial enviroment has increased the request of these type of cables for application in markets much bigger than that of industrial automation. Taking into consideration all the different installation and issues that can be found in a classic industrial environment, MotionCables is able to offer a wide range of products suitable to support Ethernet protocols where requested.
PROFIBUS standard was released in 1990 and then recognized by German DIN, European EN 50170 and international IEC 61158 and IEC 61784 standards. PROFIBUS is a linear system with two connections based on the RS 485 serial communication. The advantage of PROFIBUS is the possibility to have two different level variations (DP or Decentralized Periphery for high-speed performances and FMS or Fieldbus Message Specifications for ICT performances) in the same transmission technology. A shielded copper twisted pair is used as the means of transmission. With a transmission rate of up to 12 Mbps it can cover a distance of 100 metres.
Universal Serial Bus (USB) is an industry standard, developed in the mid-1990s, that defines all those cables, connectors and communications protocols that are generally used in a bus for connection, communication and power supply between computers and other electronic devices. USB was originally designed in order to standardize the connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, etcetera to personal computers, both to communicate and to supply electric power. It has then become commonplace also on other devices, such as smartphones, PDAs and video game consoles. USB has now effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
EtherCAT is by and large the fastest Industrial Ethernet technology, but it also synchronizes with nanosecond accuracy. This is a huge benefit for all applications in which the target system is controlled or measured via the bus system. The rapid reaction times work to reduce the wait times during the transitions between process steps, which significantly improves application efficiency. Lastly, the EtherCAT system architecture typically reduces the load on the CPU by 25 – 30 % in comparison to other bus systems (given the same cycle time). When optimally applied, EtherCAT’s performance leads to improved accuracy, greater throughput, and thus to lowered costs
