Backplane Communication and I/O Density Scaling
The PM683 operates as the central processing element within the AC 160 controller hardware structure. It exchanges controller data with connected communication interfaces and I/O structures through the system architecture.
The processor supports I/O density scaling by coordinating central S600 I/O and distributed S800 I/O configurations. Consequently, system designers can arrange controller capacity according to the installed communication and I/O architecture.
Redundant configurations can include processor, power supply, communication, and I/O bus elements. However, actual redundancy behavior and switchover characteristics depend on the complete controller configuration and installed system components.
Frequently Asked Questions
Q: Can the ABB PM683 communicate with both central and distributed I/O systems?
A: Yes. The provided specifications identify compatibility with central S600 I/O and distributed S800 I/O structures within the ABB controller configuration.
Q: Does the PM683 support redundant controller configurations?
A: Yes. The module supports system configurations incorporating CPU, power supply, communication, and I/O bus redundancy. Actual redundancy operation depends on the installed hardware and system configuration.
Q: Can the PM683 support serial communication protocols?
A: Yes. Available serial communication options include Modbus, RCOM, and Siemens 3964R, subject to the installed communication configuration.
Field Installation Guidelines
Install the PM683 only in the designated controller subrack and confirm that the rack configuration matches the ABB Advant Controller 160 system design.
Before inserting or removing the processor module, isolate system power according to the applicable controller maintenance procedure. Do not force the module into the backplane connector.
Maintain separation between controller wiring and high-power conductors. In addition, route communication cables according to the applicable shielding and grounding requirements.
Verify the installed processor configuration before system startup. Where redundant hardware is installed, check the complete redundancy configuration and communication status after commissioning.
