Information
Overview
Manuals
Common Applications
Product Precautions
AIP502 isolates and converts control-network signals between the processor side of a duplexed field control unit and the two V-Net bus connections.
- Couples duplexed processor communication to V-Net.
- Provides signal isolation and level conversion at the network boundary.
- Presents separate connections for V-Net bus 1 and bus 2.
- Indicates receive and processor-side transmit activity at the front panel.
AIP502 should be matched to the documented system position, companion hardware and retained project configuration before the channel or station is returned to control.
Important Notice: Preserve the complete AIP502 identity and verify its documented electrical, network or signal response before release.

The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.
Duplexed field control units
Connects both processor sides to the redundant V-Net path.
Legacy CENTUM network maintenance
Restores the documented control-network coupler position.
V-Net fault diagnosis
Uses receive and transmit indications to localize a communication break.
Controller retrofit preparation
Preserves bus routing and processor-side connections during planned work.
Before installing Yokogawa AIP502, confirm the documented system, interfaces and controlled configuration.
1
Confirm AIP502 and the installed style before removal.
2
Record upper and lower V-Net cable positions.
3
Label left- and right-processor connections independently.
4
Isolate the station according to the approved maintenance procedure.
5
Protect coaxial connectors and network terminators from contamination.
6
Seat the coupler fully without changing adjacent processor cards.
7
Verify RCV and both processor transmit indications after startup.
8
Confirm controller redundancy and V-Net communication before release.
Technical notes
Preserve the complete AIP502 identity and verify its documented electrical, network or signal response before release.
FAQ View All FAQ
-
What network boundary is served by Yokogawa AIP502?AIP502 couples the field control unit processor side to the V-Net control network.
-
Why is Yokogawa AIP502 associated with a duplexed processor station?The documented configuration uses AIP502 with duplexed processor cards so both processor sides can reach V-Net.
-
How are the two V-Net paths presented on Yokogawa AIP502?The coupler provides separate upper and lower network connections for bus 1 and bus 2.
-
What does the RCV indication on Yokogawa AIP502 show?RCV illuminates when the coupler receives a V-Net communication carrier.
-
Which processor activity can Yokogawa AIP502 display?Separate transmit indications identify communication from the left and right processor sides.
-
What electrical task does Yokogawa AIP502 perform between the processor and V-Net?It provides signal isolation and converts signal levels at the control-network interface.
-
Why are two coupler positions checked in a Yokogawa AIP502 installation?The duplexed field control unit uses the paired network paths to maintain the documented redundant architecture.
-
Which observations complete commissioning of Yokogawa AIP502?Normal receive and transmit indications, healthy processor redundancy and stable V-Net communication complete the check.
