Selection Suggestions and Important Notes

• Selection Suggestion:

  • Choose the ABB PM858-C 3BSE093350R1 for greenfield or major expansion projects within industries where ABB’s 800xA system is the platform of choice, or for modernizing existing ABB Advant or MOD 300 systems.

  • It is the preferred controller for applications requiring a high degree of integration between basic process control, safety functions, and high-level production management/MES systems.

  • Select this controller when the application demands high processing power for advanced control algorithms, large batch recipes, or extensive data handling.

• Important Notes:

  • System Design: The ABB PM858-C 3BSE093350R1 is part of a system. Careful planning of the associated power supply, I/O communication (CI867, etc.), and network architecture is required.

  • Licensing: Controller capabilities and memory are often enabled by software licenses applied in Control Builder M. Ensure the correct license key is procured for the required application size and functionality.

  • Firmware Management: Always use the firmware version recommended for your specific version of System 800xA and Control Builder M. Incompatibility can lead to communication failures.

  • Redundancy Configuration: Implementing controller redundancy requires a specific hardware setup (two controllers, redundancy synchronization module) and correct software configuration. This should be designed from the outset for critical applications.

  • Genuine Parts and Support: Due to its critical role, always source the PM858-C 3BSE093350R1 and its associated software from ABB or authorized distributors to guarantee authenticity, support, and compatibility.
