Features:
- Two onboard Ethernet interfaces: The R0277 configuration provides two documented network ports.
- Dedicated terminal base: ABB requires TB523-2ETH for this processor variant.
- 4 MB CPU with one serial port: The module retains PM591 processing with one configurable RS-232/485 interface.
The R0277 order code distinguishes this dual-Ethernet CPU from the single-Ethernet PM591-ETH R0271 configuration.
Each Ethernet interface provides the ABB-listed network services independently, supporting an approved two-network controller design.
Confirm TB523-2ETH, port assignments, IP ranges, routing and security policy, serial use, and the controller project before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

Two-network planning
- Port roles: Document the approved purpose of each Ethernet interface.
- Address ranges: Keep the two IP plans and subnet boundaries unambiguous.
- Services: Enable only the protocols required on each interface.
- Security: Apply the site segmentation and remote-access policy.
TB523-2ETH checks
- Base identity: Verify TB523-2ETH on the installed hardware label.
- Connectors: Match both Ethernet ports and the serial terminal arrangement.
- Module slots: Review the two communication-module positions.
- Wiring record: Save supply and network cable identification before replacement.
Dual-port startup checks
- Project: Load the approved CPU and terminal-base configuration.
- Port test: Test each Ethernet interface separately.
- Serial test: Verify the single RS-232/485 channel if used.
- Diagnostics: Resolve addressing, routing, or controller alarms before service.
