Yokogawa ALE111-S01 Ethernet Communication Module

The Yokogawa ALE111-S01, also cataloged as the ALE111 Ethernet Communication Module, operates as a dedicated hardware component for deterministic data exchange between CENTUM VP distributed control systems and external subsystem controllers via standard Ethernet infrastructure.

Process Control Network Characteristics

This module supports 4-20 mA HART loop protocol translation when interfacing analog input/output subsystems through Ethernet encapsulation. Channel-to-channel isolation is maintained to prevent ground loop formation between control nodes. Cold junction compensation is applied in connected temperature measurement subsystems to ensure signal accuracy under varying ambient conditions.

Frequently Asked Questions

Q: Does the ALE111-S01 support hot-swapping?

A: Yes, when installed in a redundant pair within supported node units, the module can be replaced without interrupting network communications.

Q: What is the switching behavior during redundancy failover?

A: Communication switchover occurs at the network stack level with no controller-side interruption; however, protocol session re-establishment timing depends on the connected subsystem firmware.

Q: Are there any backplane power restrictions?

A: The module requires 5 VDC from the node unit backplane with a maximum draw of 0.50 A; exceeding this may cause voltage drop faults in adjacent modules.

Field Installation Guidelines

Install the ALE111-S01 only in designated ESB or ER bus node unit slots. Use shielded Category 5e or higher UTP cables for runs near high-power equipment to minimize electromagnetic interference. Terminate cable shields at both ends to the node unit ground bus. Verify RJ-45 latch integrity before commissioning. When deploying in redundant configuration, synchronize firmware revisions between both modules to prevent communication handshake errors.
