Backplane Bus Communication Velocity & Profinet / EtherNet/IP Deterministic Networks
The CM572-DP processes fieldbus cycles independently of the central processing unit, executing cyclic data exchange up to 12 Mbps to maintain backplane bus communication velocity across the AC500 I/O structure. Firmware flash compatibility allows seamless integration with ABB Automation Builder software, enabling synchronization between PROFIBUS field devices and Ethernet-based deterministic networks without inducing latency on the main processor.
Frequently Asked Questions
Q: How does the CM572-DP draw operating power within an AC500 rack assembly?
A: The module snaps directly onto an AC500 communication terminal base (such as TU515 or TU516) and receives its operating logic power via the internal CPU baseboard extension bus.
Q: What transmission speeds are supported on the PROFIBUS DP interface?
A: The hardware supports standard PROFIBUS DP baud rates ranging from 9.6 kbps up to 12 Mbps with automatic baud rate detection.
Q: Can multiple CM572-DP modules be installed on a single AC500 CPU base?
A: Yes, depending on the slot capacity of the specific CPU terminal base utilized, multiple communication modules can be mounted concurrently to support separate fieldbus segments.
Field Installation Guidelines
- Ensure main AC500 CPU power and field voltage supplies are disconnected before installing or removing communication modules.
- Align the CM572-DP module with the dedicated communication slot on the AC500 terminal base.
- Press the unit firmly onto the base connection header until the side retention locking tabs click into position.
- Attach a shielded RS-485 PROFIBUS cable with standard DB9 connectors, verifying that termination resistors are switched ON at both physical ends of the network segment.
- Ground the cable shield to the cabinet earthing rail using low-impedance ground clamps to prevent electromagnetic noise interference on high-speed serial signals.

Tech & Buying Guide
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.
Voice-Activated Industrial Automation: Integrating Speech Control into PLC and DCS Architectures
Industrial automation integrates speech recognition, IIoT protocols, and NLP with PLCs and DCS to streamline operations. By leveraging advanced edge computing, engineers enable real-time, hands-free control—allowing personnel to manage smart factory processes safely away from hazardous equipment.
