Yokogawa AND50-562 Node Unit

Configured for distributed I/O expansion in Yokogawa AND50 automation architectures, the Yokogawa AND50-562 (AND50-562) Node Unit provides direct physical/electrical execution of signal conversion and multi-protocol network communication.

Hardware Specifications

Industrial Control and PLC Characteristics

• Backplane bus communication velocity: The unit manages local I/O scanning and fieldbus packet processing, ensuring deterministic data exchange between connected field devices and the master controller.
• Profinet / EtherNet/IP deterministic networks: The hardware supports multi-protocol communication, including PROFINET and Modbus TCP/IP, allowing for integration into various deterministic industrial Ethernet topologies.
• I/O density scaling: The node unit facilitates the expansion of control architectures by mapping 24 discrete and analog points to the primary control network, suitable for localized automation clusters.
• Firmware flash compatibility: The internal processor supports field-level firmware updates, enabling users to maintain communication protocol compatibility and diagnostic functionality without hardware replacement.

Frequently Asked Questions

Q: Can the AND50-562 communicate via multiple protocols simultaneously?

A: The device is designed to handle multiple communication standards (Modbus, PROFINET, CANopen); however, verify the port configuration in the engineering software to ensure specific protocol timing and bus load limits are not exceeded.

Q: Is the unit suitable for mounting in non-controlled cabinets?

A: Yes. The compact, ruggedized design is rated for industrial environments, though it must be installed within an enclosure that meets IP protection standards to prevent moisture and dust ingress.

Field Installation Guidelines

• Mounting: Secure the unit using standard industrial mounting hardware. Ensure sufficient airflow around the chassis to manage heat dissipation during peak I/O loading.
• Grounding: Bond the metallic chassis to the cabinet’s instrument earth bus via a low-impedance ground strap. This is required to maintain the stability of the analog measurement circuits and to provide a path for electromagnetic noise suppression.
• Wiring: Terminate field signals at the designated terminal blocks. Maintain at least 150 mm of separation between communication cabling (Ethernet/CANopen) and high-power AC lines to prevent induced signal jitter or data packet corruption.
