System Architecture & Signal Flow
The AB-7007-C operates as a Modbus RTU/ASCII master on the serial side, polling up to 31 slave devices on a single RS-485 bus. Collected data is mapped into an internal process image and exposed to the Ethernet side as Ethernet/IP I/O data or Modbus TCP registers. The dual RJ45 ports with integrated switch allow the unit to be inserted inline into an existing Ethernet segment without requiring an external switch. Configuration is stored in non-volatile flash memory, ensuring parameter retention across power cycles.
Signal Flow: Serial Slave Devices (RS-485) → AB-7007-C Serial Port → Internal Data Mapping (ACM-configured) → Ethernet/IP or Modbus TCP → PLC / SCADA / HMI

Technical FAQ
- Q: Can the AB-7007-C act as a Modbus TCP server (slave) on the Ethernet side?
- A: Yes. The unit supports both Ethernet/IP adapter (slave) and Modbus TCP server modes, making it compatible with any Modbus TCP master including SCADA systems and HMIs.
- Q: How many Modbus RTU registers can be mapped?
- A: Up to 512 bytes of input and 512 bytes of output data can be mapped, covering hundreds of Modbus holding registers, input registers, coils, and discrete inputs.
- Q: Is the AB-7007-C compatible with Allen-Bradley CompactLogix and ControlLogix PLCs?
- A: Yes. Via Ethernet/IP, it integrates natively with Rockwell Automation PLCs using standard Add-On Profiles (AOP) or generic Ethernet/IP module configuration in Studio 5000.
- Q: What is the difference between AB-7007 and AB-7007-C?
- A: The “-C” suffix denotes the Communicator variant with the integrated dual-port Ethernet switch and extended temperature rating. Always verify the full part number when ordering.
- Q: Can I update the firmware in the field?
- A: Yes. Firmware updates are performed via the USB service port or over Ethernet using the ACM tool, with no special hardware required.
- Q: What serial wiring topology is supported?
- A: RS-485 multi-drop bus (up to 31 nodes), RS-422 point-to-point, and RS-232 point-to-point — all selectable via software without hardware jumpers.
