The ALE111-S50 communicates with a wide range of PLC and controller protocols.

• FA-M3 (Yokogawa)

• Modbus (standard industrial protocol)

• MELSEC (Mitsubishi)

• YFGW (Yokogawa wireless gateway)

• DARWIN/DAQSTATION (Yokogawa data acquisition)

• PLC-5/SLC500 (Rockwell Automation)

Thus, the ALE111-S50 serves as a versatile gateway between Yokogawa systems and third-party equipment.

Key Features

The ALE111-S50 offers several advantages for network integration.

Standard 10BASE-T Interface:
Complies with IEEE802.3 10BASE-T specifications. Therefore, it works with standard Ethernet hubs and switches.

Point-to-Point Connection:
Connects directly to a single network device. Consequently, configuration is simple and predictable.

RJ-45 Connector:
Uses the common 8-pin modular connector. Hence, standard Ethernet patch cables can be used.

Multi-Protocol Support:
Communicates with Modbus, MELSEC, PLC-5, SLC500, and Yokogawa's own FA-M3 and DARWIN series. Therefore, it bridges disparate automation systems.

Low Current Consumption:
Draws only 0.5 A from the backplane. Thus, it adds minimal load to the power supply.

Lightweight Design:
Weighs only 0.3 kg. Consequently, it suits high-density installations.

No Explosion Protection:
The -5 suffix indicates standard type with no explosion protection. Therefore, this module is suitable for safe area (non-hazardous) installations only.

Half-Duplex Operation:
Uses CSMA/CD media access control. For this reason, it follows classic Ethernet collision detection behavior.

Typical Applications

The ALE111-S50 suits various Ethernet communication applications.

• Connecting Yokogawa FCS to Modbus TCP networks.

• Bridging Yokogawa subsystems to MELSEC PLCs.

• Interfacing DARWIN data acquisition to plant Ethernet.

• Legacy system integration with PLC-5 or SLC500 networks.

• Expanding communication capabilities of ANB/AFF/AFV base units.

Installation Guidelines

Install the ALE111-S50 in a compatible Yokogawa base unit (ANB10, ANB11, ANR10, AFF50, AFV10, AFV30, or AFV40). First, ensure the base unit power supply can provide the required 0.5 A. Then, insert the module into an available slot.

Connect a standard RJ-45 terminated Ethernet cable to the module's port. Use 100 ohm unshielded twisted-pair cable. The maximum cable length is 100 meters. For point-to-point connections, connect directly to the target device or to a hub/switch.

Configure the module for the desired protocol (Modbus, MELSEC, etc.). The transmission is half-duplex at 10 Mbps. No special shielded cable is required.
