Description
The Yokogawa AIP591 is an optical transceiver unit designed for use within Yokogawa CENTUM CS, CENTUM CS 3000, and CENTUM VP distributed control system (DCS) architectures. It serves as a critical network interface component for Vnet / Vnet/IP repeater systems, facilitating long-distance, noise-immune optical fiber communication between distributed nodes and field control stations.

Engineering and Integration Notes
In field deployments connecting large-scale industrial plants, the AIP591 bridges remote control nodes over optical media, eliminating electromagnetic interference (EMI) risks inherent in long copper cable runs.
- Optical Budget & Attenuation: When designing long-distance Vnet segments up to 15 km, measure total optical link loss and ensure attenuation values remain well within the transceiver receiver sensitivity threshold. Clean all fiber end-faces prior to insertion to prevent high bit-error rates.
- Redundancy & Topology: Verify dual-redundant Vnet cable routing rules if utilizing dual optical paths. Loss of a primary optical link triggers automatic switchover to the secondary network path provided the system architecture is configured for dual-redundant bus monitoring.
- Handling & ESD Precautions: Observe standard electrostatic discharge (ESD) precautions when handling the module during installation or replacement in node interface cabinets.
Frequently Asked Questions
What is the primary function of the AIP591 in a CENTUM system?
The AIP591 acts as an optical transceiver unit for the Vnet repeater infrastructure. It converts electrical control network signals into optical signals, allowing safe and reliable data transmission across distant plant units up to 15 km away.
Are different suffix codes (such as AIP591-S1) interchangeable?
Suffix and option codes typically designate specific hardware revisions, optical wavelength profiles, or regional compliance standards. Always verify exact part code compatibility against your existing node bill of materials (BOM) or OEM datasheet before field replacement.
