Firmware Flash Compatibility
The PM573 processor stores firmware and application resources in onboard flash memory. Consequently, firmware revisions directly influence compatibility between the CPU, engineering software, communication services, and connected AC500 expansion hardware.
Before loading a new application or updating controller firmware, engineers should verify the compatibility matrix between the installed Automation Builder version, processor firmware revision, and attached I/O modules. In addition, project migration between different firmware generations may require validation of communication parameters, memory allocation, and hardware configuration settings.
Frequently Asked Questions
Q: Does the PM573 provide integrated Ethernet communication?
A: Yes. The processor includes an integrated Ethernet interface that supports controller communication, engineering access, and data exchange functions within the AC500 platform.
Q: Can firmware revisions influence hardware compatibility?
A: Yes. ABB recommends verifying firmware compatibility with the engineering environment and installed AC500 modules before performing firmware upgrades or application downloads.
Q: Does the documentation specify processor hot-swapping capability?
A: No. The available documentation does not specify hot-swap support. Therefore, maintenance personnel should remove controller power before replacing the processor unless ABB service instructions state otherwise.
Field Installation Guidelines
Mount the processor on the designated AC500 DIN rail and confirm complete mechanical engagement before applying power.
Next, verify that the incoming supply voltage matches the controller requirements and that protective earth connections remain intact throughout the installation.
Route Ethernet and serial communication cables separately from motor feeders, contactor wiring, and other high-current conductors. This separation helps reduce electromagnetic interference and communication disturbances.
Additionally, terminate cable shields according to plant grounding practices and maintain continuous shield bonding where required by the installation standard.
Before startup, inspect all expansion modules, terminal connections, and backplane interfaces for correct seating. Then verify controller addressing, communication parameters, and firmware compatibility to ensure proper commissioning.
