-
Proven Platform and Support: As part of the massively successful Series 90-30 family, it benefits from an enormous installed base, extensive documentation, and deep knowledge pools among technicians and integrators worldwide.
Application Cases in Application Fields
-
Mid-Size Manufacturing Cells: Controls a complete robotic welding cell, managing the robot interface (via serial), weld controller, clamp sequencing, and safety interlocks.
-
Material Handling Systems: Acts as the main controller for a complex conveyor and sortation system in a distribution center, coordinating multiple drives and scanner inputs.
-
Water Treatment Processes: Manages the automated backwash sequence for multiple filter beds, controlling pumps, valves, and monitoring analog flow and pressure signals.
-
Packaging Lines: Coordinates several machines (filler, capper, labeler) on a production line, using its communication ports for peer-to-peer data exchange and HMI connectivity.
Comparisons with Competing Products
The GE IC693CPU364-FK competes within the context of mid-range PLCs from its era and for legacy upgrades:
-
Within the 90-30 Family: It is a clear upgrade over the CPU331/341 models, offering more memory, faster speed, and the integrated RTC. Compared to the premium CPU374 (with Ethernet), the CPU364-FK is a high-performance serial-focused CPU.
-
Competing Contemporary PLCs (e.g., Allen-Bradley SLC 5/04): The IC693CPU364-FK typically offered competitive or superior memory and I/O capacity at a lower cost. Its integrated dual serial ports provided flexibility, while competitors often required separate modules for a second port.
-
Modern Micro-PLCs: Compared to today’s compact PLCs with built-in Ethernet and USB, the CPU364-FK lacks modern connectivity but often surpasses them in raw I/O capacity, ruggedness, and suitability for harsh industrial environments. Its value is in maintaining and upgrading existing systems.
-
Third-Party/Refurbished CPUs: While refurbished units exist, a new or guaranteed genuine GE IC693CPU364-FK ensures full firmware compatibility, reliable battery performance for the RTC, and known condition, which is critical for a system’s core component.
Selection Suggestions and Precautions
-
Assess I/O and Memory Requirements: Carefully count all discrete, analog, and special I/O points and estimate the logic program size to ensure the IC693CPU364-FK‘s capacity is sufficient with room for future growth.
-
Plan Communication Needs: Determine if the integrated serial ports are adequate (e.g., one for programming/HMI, one for a network like Genius). If Ethernet is required, you will need to add a separate Ethernet communication module (CMM).
-
Battery and RTC Maintenance: The CPU has a lithium battery to maintain the real-time clock and memory. Plan for periodic battery replacement (every few years) to prevent loss of clock and program on power loss. The official product link for support is: GE IC693CPU364-FK.
-
Firmware and Software Compatibility: Ensure you have the correct version of Proficy Logic Developer software that supports this CPU. Check if a specific firmware version is required for any special modules in your rack.
-
Source from Reputable Suppliers: As the critical component of your control system, purchase the GE IC693CPU364-FK from authorized Emerson channels or highly reputable automation specialists. Always back up the program from the old CPU before replacement. When installing, follow proper ESD procedures and ensure the rack power supply is adequate for the CPU and all installed modules.
