Key Product Advantages
-
High Processing Power: With a 2MB program memory and rapid cycle times, it can handle complex control logic and large-scale data processing with ease.
-
Integrated Ethernet: The built-in Ethernet port allows for seamless integration into factory networks, enabling remote programming, web visualization, and peer-to-peer communication.
-
Scalability: Part of the AC500 ecosystem, it allows users to mix and match I/O modules and communication couplers to fit specific project needs.
-
Reliability: Designed for harsh industrial environments, offering high vibration resistance and electromagnetic compatibility (EMC).
-
Standardized Programming: Built on the CODESYS standard (IEC 61131-3), making it easy for engineers to program using familiar languages like Ladder or Structured Text.
Important Considerations & Precautions
-
Terminal Base Required: The PM590-ETH is a processor module only. It must be mounted on a compatible Terminal Base (e.g., TB511-ETH or TB521-ETH) to function.
-
Firmware Compatibility: Ensure that the version of ABB Automation Builder software you are using is compatible with the CPU’s firmware version to avoid communication errors.
-
Battery Backup: While the unit has retentive memory, ensure the lithium battery is checked periodically if your application requires long-term data storage during power outages.
-
Wiring: Always disconnect the power supply before plugging or unplugging the CPU from the terminal base to prevent electrical damage.
Typical Applications
The PM590-ETH is widely used across various industries due to its versatility:
-
Renewable Energy: Wind turbine control systems and solar farm monitoring.
