Product Details
Yokogawa ANR10S-315 / ANR10D-415 are ER Bus Node Units for CENTUM VP field I/O. ANR10S-315 uses single power, while ANR10D-415 uses dual-redundant power; both retain the selected 100–120 V AC and basic non-explosion-protected execution.
On the ER Bus, Yokogawa ANR10S-315 / ANR10D-415 provide the physical node position for installed FIO modules and the communication path back to the field control unit. Node position, bus direction and module-slot ownership must match the system configuration.
For service work, Yokogawa ANR10S-315 / ANR10D-415 should be recorded with power execution, upstream and downstream bus connections and installed-module list. This separates a redundant-feed problem from a bus interruption or missing I/O module.

Product Functions
Yokogawa ANR10S-315 / ANR10D-415 extend the controller I/O path across the ER Bus while preserving physical slot ownership for field modules. Each point below explains how the selected article works with the surrounding system rather than restating its specification rows.
Host the I/O Slots
Keep every installed module assigned to the matching physical and project position. Keep channel ownership and interface roles explicit so adjacent hardware does not inherit a function that belongs to this exact article.
Report Node State
Use power, bus and module indications to separate node faults from field-channel faults. Functional acceptance should demonstrate the intended path under the saved configuration, not merely confirm that the product is powered.
04
Operating Characteristics
The S and D executions of Yokogawa ANR10S-315 / ANR10D-415 share the same node role but behave differently when one power feed is lost. The emphasis is on state transitions and dependencies during real operation, rather than repeating the numeric limits already listed in the specification table.
Understand Single Power
ANR10S depends on its one verified supply path and should be tested accordingly. Observe startup, ready, backup and degraded states as a sequence; a final ready indication alone does not show whether redundancy or a downstream path was lost.
Verify Redundant Power
ANR10D should remain observable on either feed, with each path checked separately. Keep supply, network and node behavior within the selected execution, and investigate unexpected transitions before returning the station to automatic control.
Restore Bus Sections Gradually
After service, reconnect nodes in sequence and confirm controller recognition before field testing. Record the stable operating result under the same project and hardware revision used during commissioning so later comparisons remain meaningful.

Product Q&A
What is the operational difference between the two articles in Yokogawa ANR10S-315 / ANR10D-415?
ANR10S-315 uses a single power path, while ANR10D-415 uses dual-redundant power. Their ER Bus node role is shared, but power-test and fault-isolation procedures must reflect the selected article.
How can a missing module behind Yokogawa ANR10S-315 / ANR10D-415 be isolated?
Compare physical slot order with the controller project, then check node recognition and ER Bus continuity before moving the module. This keeps a project-position problem from being mistaken for failed hardware on Yokogawa ANR10S-315 / ANR10D-415.
How should the bus be restored after fitting Yokogawa ANR10S-315 / ANR10D-415?
With wiring and polarity checked, energize Yokogawa ANR10S-315 / ANR10D-415, verify the node and bus indicators, then enable downstream sections in sequence. Confirm the controller recognizes each expected module before field testing.
What information prevents the wrong Yokogawa ANR10S-315 / ANR10D-415 variant from being supplied?
State whether the node is single or dual power, the required bus or optical-repeater execution, supply voltage and explosion-protection code along with the complete Yokogawa ANR10S-315 / ANR10D-415 string.
When is the bus cable or fibre more suspect than Yokogawa ANR10S-315 / ANR10D-415?
If node power and configuration are correct but link status changes with cable movement or route substitution, test the cable, connector faces, bends and termination used by Yokogawa ANR10S-315 / ANR10D-415 before replacing the node.
How should Yokogawa ANR10S-315 / ANR10D-415 be selected for an existing I/O bus?
Match the complete Yokogawa ANR10S-315 / ANR10D-415 suffixes to the bus type, power redundancy, optical reach where applicable, supply voltage and basic execution. The physical node must agree with the controller and bus design.
