ABB Industrial Control and Ethernet Communication Characteristics

The TU860 is specified as an Ethernet Fieldbus Communication Interface Module for the ABB System 800xA hardware environment. It handles the physical interface required for Ethernet fieldbus communication rather than serving as a general-purpose I/O channel.

The supplied data does not specify Ethernet protocol variants, transmission speed, connector type, firmware revision, or backplane communication parameters. Therefore, these values should be verified against the applicable ABB System 800xA hardware documentation before system integration.

The module is specified for operation from -20 deg C to +70 deg C and storage from -40 deg C to +85 deg C. Relative humidity must remain within 5-95% non-condensing.

Frequently Asked Questions (FAQ)

Q: What is the primary function of the ABB TU860?
A: The TU860 provides an Ethernet fieldbus communication interface within the ABB System 800xA hardware environment.

Q: Does the supplied specification define the TU860 power consumption?
A: No. The supplied data does not provide a specific power-consumption value. The actual system load should therefore be determined from the applicable ABB technical documentation.

Q: What environmental conditions does the TU860 support?
A: The specified operating temperature is -20 deg C to +70 deg C. Storage temperature is -40 deg C to +85 deg C, with 5-95% non-condensing humidity.

Field Installation Guidelines

• Install the TU860 according to the ABB System 800xA hardware installation requirements.
• Verify the module identity and complete ordering code before installation.
• Ensure that the mounting arrangement provides adequate mechanical support and prevents connector stress.
• Route Ethernet and fieldbus communication wiring separately from high-current power wiring where practical to reduce electromagnetic interference.
• Maintain proper cable shielding and terminate the shield according to the system grounding design.
• Verify conductor ratings against the specified voltage and current limits before field connection.
• Do not apply field power until wiring polarity, conductor termination, grounding, and connector engagement have been checked.
• Confirm environmental conditions remain within the specified temperature and humidity limits.
• Do not assume hot-swap capability unless the applicable ABB System 800xA documentation explicitly permits live replacement for the installed configuration.
