Deterministic Network Integration and I/O Density Scaling
The CM579-ETHCAT module plugs directly into the AC500 CPU terminal base, expanding communication velocity across Profinet and EtherNet/IP deterministic networks as well as dedicated EtherCAT master field loops. By processing high-speed protocol frames off the main controller CPU, it optimizes internal backplane bus communication velocity and supports vast I/O density scaling across distributed drive and field bus topologies. Onboard firmware flash compatibility permits field updates without interrupting system wiring.
Frequently Asked Questions
Q: How is the CM579-ETHCAT module powered within the system rack?
A: The module draws operational power directly from the internal backplane bus supplied by the attached AC500 CPU or terminal base connection.
Q: Does the module support hot-swapping during active PLC execution?
A: Module replacement requires the local backplane segment or CPU unit to be de-energized to prevent bus communication faults or physical connector damage.
Q: What data transmission rate is supported on the RJ45 Ethernet ports?
A: The module operates at a fixed transmission rate of 100000 kbit/s (100 Mbit/s full-duplex) for real-time EtherCAT fieldbus communications.
Field Installation Guidelines
- Verify that the AC500 terminal base and CPU power supplies are disconnected before mounting or removing the module.
- Align the side terminal connectors precisely with the AC500 CPU or adjacent communication module to prevent pin bending on the backplane interface.
- Use shielded twisted-pair (STP) Cat 5e or higher Ethernet cabling with grounded RJ45 connectors to comply with IP20 noise immunity requirements.
- Maintain a minimum clearance of 25 mm around the module vents to ensure free air convection across internal circuitry.

Tech & Buying Guide
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
Safety Relays in Industrial Automation: Fundamentals, Design Standards, and Fail-Safe Architecture
Safety relays form the bedrock of functional safety in modern factory automation, preventing catastrophic equipment failure and protecting plant personnel. While standard electromechanical relays handle basic load switching, they lack the redundant diagnostics required for high-risk industrial environments. Modern industrial automation platforms—including programmable logic controllers (PLCs) and distributed control systems (DCS)—rely on specialized safety relays to monitor field devices and isolate hazards instantly.
