ACG10S-F2123

The Yokogawa ACG10S-F2123 is a Communication Gateway Unit (CGW) for Yokogawa CENTUM CS 3000 and CENTUM VP distributed control systems. Configured for Frame Mode wide-area communication with LGW1250 software support, it provides a communication path between Ethernet-connected supervisory systems and the V net control network. The supplied model description identifies a dual-redundant V net interface, 19-inch rack mounting, and a 100-120 V AC power supply.

Function and Communication Interfaces

The ACG10S-F2123 is intended to exchange data between the DCS control network and external supervisory or interconnected systems. Its gateway role separates the external Ethernet communication path from the V net real-time control network, allowing supported data exchange without treating the external network as a direct V net connection.

The supplied specifications list 10BASE-T, 10BASE-5, and 100BASE-TX Ethernet interfaces, together with a dual-redundant V net interface. Confirm the supported physical port configuration and connection requirements against the applicable hardware documentation before installation or replacement.

Power Supply and Mounting

The model suffix identifies the unit as a general-purpose 19-inch rack-mountable configuration with a dual-redundant V net interface. The final configuration digits also identify the power supply and software license; these details should be checked against Yokogawa's published model and suffix code table before ordering.

Frequently Asked Questions

Q: Which gateway software is required for the ACG10S-F2123?

A: The -F configuration uses the LGW1250 Frame Mode Gateway Unit Function for wide-area communication. The applicable software license and system release must be verified for the intended CENTUM installation.

Q: What does the dual-redundant V net configuration mean?

A: The model suffix specifies a dual-redundant V net interface using 10BASE-5. Confirm the existing network topology and cabling before replacing a unit, because the interface configuration must match the installed control network.

Q: Can the ACG10S-F2123 be used with a 100-120 V AC supply?

A: The published suffix-code table assigns power-supply code 1 to 100-120 V AC and code 2 to 220-240 V AC. Since this model ends in 2, the documented configuration is 220-240 V AC, not 100-120 V AC.
