Yokogawa ALE111-S53 Ethernet Communication Module

Hardware Specifications

Ethernet Communication and DCS Integration

The ALE111-S53 processes Ethernet communication through its 10BASE-T interface. Its RJ-45 port connects the module to an external subsystem or network hub using 100-ohm UTP cabling.

The module supports Modbus slave communication and DNP3 slave functions. Consequently, external supervisory systems can exchange data with the control system through the configured communication interface.

For DNP3 applications, the module can generate and timestamp events when application logic variables change. This event-buffering function supports event retention during temporary communication interruptions.

Furthermore, paired ALE111-S53 modules can provide independent transmission paths in a dual-redundant network configuration. This arrangement separates the communication paths rather than relying on a single network connection.

The module also features ISA Standard G3 corrosion resistance through conformal coating. Its specified environmental construction supports installation in industrial environments subject to corrosive atmospheric conditions.

Frequently Asked Questions (FAQ)

Q: Which Ethernet physical interface does the ALE111-S53 support?

A: The module supports IEEE 802.3 10BASE-T Ethernet at 10 Mbps in half-duplex mode. It uses one RJ-45 port and 100-ohm UTP cabling.

Q: Does the ALE111-S53 support redundant Ethernet communication?

A: Yes. Paired modules can provide independent transmission paths in a dual-redundant network configuration.

Q: What is the current consumption of the ALE111-S53?

A: The specified current consumption is 0.5 A. The input voltage and corresponding power consumption are not provided in the supplied specifications.

Field Installation Guidelines

1. Install the ALE111-S53 in its designated Yokogawa system hardware location according to the applicable system installation documentation.
2. Connect the RJ-45 interface to the external Ethernet network using 100-ohm UTP cable.
3. Keep Ethernet communication cables separated from power wiring and high-interference signal cables.
4. Maintain the specified maximum transmission distance of 100 m per Ethernet segment.
5. For redundant configurations, use paired modules with independent communication paths.
6. Verify Modbus slave or DNP3 slave configuration against the connected subsystem requirements.
7. Confirm communication settings and network connectivity before placing the interface into service.
8. Follow the system manufacturer’s grounding, shielding, and installation requirements. Do not assume an unsupported shield termination arrangement.
9. Inspect the module and connector for physical damage before installation.
