YOKOGAWA AIP571 BUS2
Product Name
YOKOGAWA AIP571 BUS2 Vnet/IP interface module
Product Introduction
The Yokogawa AIP571 is a communication interface module for CENTUM VP and ProSafe-RS systems. The BUS2 designation identifies the second control network port or bus connection. Its role is to connect a control station or processor to the Vnet/IP control network.

Working Principle
The module converts internal control-station data into Vnet/IP Ethernet frames and transmits them to other control stations, I/O nodes, and engineering or operation stations. It monitors link status and transfers process control data across the dedicated control network. In a dual-bus system, BUS1 and BUS2 provide separate physical network paths.
Installation Requirements
- Install only in the designated AIP571 slot
- Use the supported processor and base unit combination
- Use Cat5e or Cat6 shielded cables for short, controlled segments where permitted
- Follow Yokogawa network topology and distance rules
- Verify system and firmware compatibility before installation
- Use ESD protection when inserting the module
Usage Precautions
- AIP571 modules with different functions and network types may share the same base name; confirm the full part number.
- Do not connect office or general-purpose switches without verifying system compatibility.
- Verify cable length and network termination requirements.
- Redundancy behavior depends on the complete system architecture.
- Backup configuration data before replacing network hardware.
