Product Features

Bus Termination: The ABB TER800 is mainly used to terminate the HN800 or CW800 bus. Termination: In bus - based communication network, termination is important. The important function of the TER800 is to absorb the electrical signals at the end of the bus line and thus to prevent signal reflections. This tendency for a signal to reflect off of nearby structures can cause interference, which can result in communication errors. ABB TER800 acts to remove these reflections providing reliable stable communication in any industrial network.

Enhanced Signal Integrity: This is also passively terminated, which helps improve the overall signal integrity of the bus system. There are often multiple sources of electromagnetic interference common in industrial environments. Its features also encompass electromagnetic interference filtering that allows signals traveling along the entire bus to be free from unwanted noise, disturbances, and electrical activities. As a result, the data transmitted between the devices such as programmable logic controllers, sensors and actuators connected to HN800 or CW800 bus, becomes accurate.

High Reliability Design: Built-in for high-availability in mission-critical industrial applications.

Modular design: Facilitates seamless incorporation into current control systems.

Diagnostic Functions:The diagnostic function diagnostics feature test faults.

Installation

Identify Bus Ends: Determine the physical endpoints of the HN800 or CW800 bus within your system architecture.

There are two steps to mount the terminators: Step 1: Identify where the bus endpoints are. Step 2: Install a ABB TER800 terminator at each located bus endpoint Make sure that terminators are firmly in place for proper termination.

Verification: Once installed, verify the integrity of the bus communication to ensure that terminators are functioning correctly and that signal reflections or communication errors do not exist.

Application Range

Industrial Automation: The ABB TER800 is extensively utilized in industrial automation systems, particularly in manufacturing plants. It plays a fundamental role in factory scale networks systems which link diverse automated machines like robots, conveyor systems and automated production lines. For instance, an automotive manufacturing plant uses it to enable the transfer of information between different PLC powered stations on an assembly line so that vehicles can be transferred and produced effectively when they are needs during the manufacturing process.

Power Generation and Distribution: The ABB TER800 is used in control systems at power plants and electrical substations which monitor and manage power generation and distribution. It allows for dependable communication between sensors, control devices, and monitoring systems. Such as in a wind farm, it is also used in the communication network controlling the working of wind turbines, where it allows to transmit and receive the data pertaining to turbine performance, power output, and safety parameters effectively.

Process Industries: The ABB TER800 is used in the control networks of process industries like chemical, oil and gas, and food and beverage, which all require continuous process control. It makes sure that signal from the sensors, which measure parameters such as, temperature, pressure and flow rate, can be passed on to the control systems in a precise manner. For instance, in a chemical plant, it makes possible the feedback between the sensors located in the reaction vessels and the central control room so that operators can monitor and tweak the chemical processes as they happen.

Troubleshooting

Communication Failures:  If you see no HN800 or CW800 bus communication, inspect the connections first. Give the wires a firm but gentle tug to see if any loose or damaged connections might be quick signal disruptions. Check for any fraying in the wires and ensure that the cables are plugged in properly. If the connections are good, then check the termination setting that is configured in the ABB TER800. Using wrong termination resistance, it may also generates signal reflections which can be cause communication errors.

Electrical Interference: In case of observing effects, attributed to electrical noise on the bus, like erroneous data output or repeated communication failure, validate grounding. If the grounding is not good, it will make the device more susceptible to noise. Also, make sure your bus cables are well shielded and routed away from other sources of electromagnetic interference.

Device Malfunction With Device: If the seems to be malfunctioning, inspect the for any visible signs of damage, like burnt components or cracked casings. Finally, in some cases, you will need to flush a firmware update that will fix any arisen issues with the software.
