Product Description

The ABC11S is a high-performance communication gateway designed to bridge modern Yokogawa CENTUM VP Human Interface Stations (HIS) with legacy and diverse CENTUM system architectures. It enables seamless data exchange between the V net and older network types such as VL, HF, and RL buses used in Yokogawa CENTUM CS 1000 and Yokogawa CENTUM CS 3000 environments. This ensures unified supervisory control across multi-generation systems.

Operating at a stable 10 Mbps, the ABC11S provides reliable, real-time data communication. It uses coaxial cabling with N-type or BNC-type connectors to maintain signal integrity and minimize electromagnetic interference in industrial environments. For complex system integration, it is typically used with software packages such as LHS4450 and LHS5450, enabling a consolidated view of process data across multiple networks and projects.

Technical Specifications

Application Context

The ABC11S is commonly used in large-scale industrial facilities such as:

• Refineries

• Pharmaceutical manufacturing plants

• Power generation stations

It is especially valuable in brownfield environments where legacy Yokogawa CENTUM CS 3000 or Yokogawa CENTUM CS 1000 systems must be integrated into a modern CENTUM VP control infrastructure. This enables cost-effective system expansion without requiring full network replacement.

FAQ

Which software packages are required for the ABC11S to function?
The ABC11S requires the LHS4450 Multiple Project Connection Package and the LHS5450 Multiple Project Connection Builder. These provide the necessary drivers and configuration tools for enabling cross-network communication.

What type of cabling is used on the V net side?
The V net side typically uses YCB111 or YCB141 coaxial connector assemblies. Proper shielding and cable selection are important to maintain stable 10 Mbps communication performance.
