Engineering Advantages
The PM573-ETH 1SAP130300R0271 provides specific mechanical and digital advantages for modern control cabinets:
-
Extended Thermal Tolerance: Engineered for extreme environments, this CPU operates in temperatures ranging from -30°C to +70°C. This eliminates the need for cabinet heaters in arctic conditions or oversized cooling units in high-heat industrial zones.
-
Seamless Fieldbus Expansion: The PM573-ETH supports side-stacking of communication modules like the CM577 (Profinet) and CM572 (Profibus DP). This modularity allows the PLC to act as a multi-protocol gateway without increasing the system depth.
-
Integrated Ethernet Diagnostics: The onboard 10/100 Mbps Ethernet port supports Modbus TCP and HTTP protocols. Maintenance teams access internal diagnostics and variables via a standard web browser, reducing the need for proprietary handheld tools.
-
Deterministic Program Retention: The 128 KB battery-backed SRAM secures mission-critical data during power interruptions. This ensures the PLC resumes its exact state immediately upon power restoration, preventing material waste in batch processing applications.
FAQs
Is the PM573-ETH 1SAP130300R0271 compatible with legacy AC500 modules?
Yes. The PM573-ETH maintains full backward compatibility with the AC500 series terminal units and I/O modules. It integrates directly into existing racks, allowing for easy CPU upgrades while retaining current I/O infrastructure.
How does the extended temperature range benefit my installation?
Standard PLCs often fail or require derating above 55°C. The PM573-ETH’s -30°C to +70°C rating ensures reliability in uninsulated utility kiosks, power generation sites, and outdoor water treatment facilities where environmental control is limited.
Which software do I use to program the PM573-ETH?
You program the module using ABB PS501 Control Builder (Automation Builder). It supports all five IEC 61131-3 languages, including Ladder Logic (LD) and Structured Text (ST), providing flexibility for different engineering preferences.
Does the module ship with a battery?
The CPU includes the internal circuitry for battery backup, but the lithium battery (typically TA521) is often managed as a separate maintenance item. We recommend installing a fresh battery during commissioning to ensure the 128 KB SRAM remains protected.
