Procontrol P14

High performance devices for internal and external system communication


One of the unique strengths of P14 is its fully redundant high-speed and deterministic remote bus communication. All process signal changes are available in real-time for each process station in the system. This enables related process control functions to be located either together in one station, or distributed between several stations. The process stations are connected via redundant communication modules to the remote bus based on the High Availability Seamless Redundancy Protocol (HSR) according to IEC 62439-3.5. HSR guarantees high availability of the control system through uninterrupted communication without a single point of failure. All data packets are sent to the HSR ring via two independent fiber optic ports. A transmission in both directions ensures that one of the two data packets arrives at the receiver even if the ring is interrupted. Additional hardware redundancy through two synchronized communication modules, robust design and comprehensive diagnostic capabilities ensure that the system is maximally available at all times. Optical fiber cables are used for the connections. These are insensitive to electromagnetic interference and can transmit data over distances of up to 2,000 m between stations, and at a high data transfer rate of 100 Mbit/s. Maximum network sizes of up to 100 km can be achieved.

 

Specific communication modules are available for connecting P14 to the HMI and engineering systems, as well as external control systems and automation devices.

 

 Why ABB?

  • Easy online network extension and availability of all process variables via redundant remote bus in real-time
  • Self-learning system, so no configuration and engineering of communication system required
  • New module provides communication via Ethernet between P14 process stations and the engineering tools EDS and PDDS
