Product information
01

Dual Ethernet Interface Architecture

Two independent RJ45 channels, protocol support and CPU-wide limits.

ABB defines this AC500 communication module as a CPU port extender with two independent Ethernet channels rather than an unmanaged two-port switch.

Identity, Ports & Supply 8 verified fields
Manufacturer ABB
Order code 1SAP176000R0080
Product family AC500
Module type Ethernet port extender
Ethernet interfaces 2
Connector type RJ45
Independent channels Yes
Usable terminal bases TB56xx
Protocols, Access & System Limits 8 verified fields
TCP/IP Supported
UDP Supported
Modbus TCP Supported
Programming access 3S Online Protocol

Net weight 0.12 kg
Protection IP20 with terminals fitted
Lifecycle status Active
01
CPU-managed communicationThe connected CPU continues to execute the protocol stacks; the module extends physical Ethernet access but does not become an independent controller.
02
Separate networksETH1 and ETH2 are independent interfaces and must be configured on different IP subnets.
03
Shared communication limitsSocket, tag and protocol limits remain CPU-wide. Adding this module does not multiply the controller's communication resources.
04
Gateway ruleABB permits only one active default gateway across the CPU and communication-module Ethernet interfaces.
02

Network Segmentation & AC500 Integration

A correct installation depends on CPU generation, firmware, independent subnet planning and the exact Ethernet service required by the application.

Application checkpoints
01
Separated machine networksUse the two independent ports to connect the controller to distinct Ethernet segments while keeping their IP subnets different.
02
Modbus TCP communicationThe module supports Modbus TCP through the CPU communication stack for controller, HMI or supervisory data exchange.
03
Engineering accessABB lists 3S Online Protocol for programming and online access through the module.
Conversion checkpoints
01
Firmware baselineThe hardware manual requires compatible AC500 V3 CPU firmware; core CM5640 functions require version 3.6.0 or later.
02
Optional PRP useABB offers a separately licensed PRP function for parallel redundant networks on supported AC500 V3 systems.
03
XC comparisonCM5640-2ETH-XC is the extreme-condition counterpart. Match environmental requirements and the full order code before purchase.

Buyer Questions for ABB CM5640-2ETH

Network architecture, CPU compatibility, protocol limits, lifecycle and quotation checks.

01 Are the two Ethernet ports on ABB CM5640-2ETH a built-in network switch?
No. ABB specifies two independent Ethernet interfaces. Configure ETH1 and ETH2 on different IP subnets instead of treating them as two switched sockets on one network.
02 Which CPU firmware is required before installing ABB CM5640-2ETH?
ABB's hardware manual requires an AC500 V3 CPU with firmware version 3.6.0 or later for the core communication-module functions. Additional protocol features can require newer firmware or licenses.
03 Does ABB CM5640-2ETH increase AC500 socket, tag or protocol connection limits?
No. The CPU still executes the communication stacks, so the controller-wide socket, tag and connection limits remain shared across its onboard Ethernet and both module interfaces.
04 Can ABB CM5640-2ETH use a default gateway on both independent interfaces?
No. ABB permits only one active default gateway across all Ethernet interfaces in the controller configuration. Route and subnet planning must be completed before commissioning.
05 Is ABB CM5640-2ETH still an active product, and is there an extreme-condition version?
ABB lists order code 1SAP176000R0080 as Active. ABB also lists CM5640-2ETH-XC, order code 1SAP376000R0080, for extreme-condition applications; it is not selected by changing only a software setting.
06 What information is needed to quote ABB CM5640-2ETH accurately?
Send the full nameplate, quantity, destination, required delivery date, host CPU model and firmware, required protocols, and confirmation of standard versus XC construction.

Transaction Cases

Sincere Cooperation, Long-Term Trust

Three customer journeys showing careful verification, clear communication and repeat cooperation.

Russia 01
A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
India 02
An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
Venezuela 03
A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
