📖 Operating Instructions
Installation and setup require familiarity with the RTU560 configuration tools:
-
Mounting: Snap the unit onto a standard 35mm DIN rail. Ensure there is at least 50mm of clearance above and below for adequate airflow and cooling.
-
Wiring: Use the provided terminal blocks for DC power supply (typically 24V or 48V/60V depending on the power supply module used). Connect Ethernet and serial cables according to the project’s communication diagram.
-
Configuration: Utilize the RTUtil560 software to define the device’s logic, signal mappings, and communication parameters.
-
Booting: Once powered, the status LEDs will indicate boot progress. Green indicates normal operation; flashing red or amber signals a configuration error or hardware fault.
-
Firmware: Always keep the unit updated with the latest signed firmware from ABB to maintain current security patches.
❓ Frequently Asked Questions
What is the difference between these two part numbers (1KGT008800R0002 vs 1KGT008810R61)? These numbers typically represent different manufacturing revisions or factory configurations. The “R61” variant often implies a specific firmware pre-load or a revision update that offers improved processing capability or extended memory compared to the original “R0002”. Always check the label on the chassis to confirm the exact model revision in use.
Does this unit support IEC 61850? Yes, the 560CMU80 is fully capable of acting as an IEC 61850 client or server, making it a standard choice for modern digital substation upgrades.
How is the device reset to factory settings? Physical resetting requires a special configuration file upload or a specific hardware jumper sequence defined in the manual. Do not attempt a reset without a backup of the current .rtr configuration file.
What is the “CMU” role in the rack? The CMU is the “brain.” It manages the bus traffic between the power supply module and the various I/O modules, ensuring that all data packets are timestamped and transmitted to the SCADA host with microsecond precision.
