Country of Origin
This controller is engineered and manufactured by GE / Emerson in the USA or Germany, depending on the specific hardware revision, adhering to global industrial automation standards.
Application Fields
The EPSCPE100-ABAC is a versatile logic engine used in various sectors:
- Machine Automation: Controlling packaging lines, labeling machines, and assembly stations.
- Food & Beverage: Managing mixing tanks, pasteurization processes, and conveyor logic.
- Water & Wastewater: Operating small-scale pumping stations and treatment units.
- Renewable Energy: Monitoring solar tracking systems and wind turbine auxiliary controls.
- Infrastructure: Building automation and localized HVAC management.
Product Usage Instructions
- Mounting: Install the CPU on a standard 35mm DIN rail. Ensure there is sufficient clearance for airflow to prevent overheating of the processor.
- I/O Integration: Connect RSTi-EP I/O modules directly to the right side of the CPU. The local bus provides high-speed communication between the CPU and the slices.
- Networking: Utilize the three Ethernet ports for different network segments (e.g., one for the plant network, one for PROFINET I/O, and one for HMI connection).
- Programming: Use PAC Machine Edition to develop your logic. The controller supports Ladder Diagram (LD), Structured Text (ST), and Function Block Diagram (FBD).
- Security: Take advantage of the built-in OPC UA with encryption to ensure secure data transmission to cloud-based or SCADA systems.
Product Technical Description
The EPSCPE100-ABAC is built on the PACSystems technology, which means it shares the same execution engine as the larger RX3i controllers. This allows for seamless code portability across the GE/Emerson ecosystem. Technically, it is a “Linux-based” real-time controller, providing a secure and stable environment for logic execution. It features an integrated PROFINET I/O controller, eliminating the need for separate communication modules. The “ABAC” revision typically refers to specific hardware packaging and firmware bundling tailored for high-speed industrial networking. Its dual-core processor allows it to handle complex math and communication tasks simultaneously without impacting the logic scan time.
Q&A (Common Questions)
- Q: Does this CPU require a separate power supply module?
- A: It requires 24 V DC power. While it has an integrated power terminal, you must ensure the total current draw for the CPU and attached I/O slices does not exceed the internal bus limits.
- Q: Can I use this for motion control?
- A: Yes, it can manage motion via PROFINET or through specialized motion modules within the RSTi-EP I/O family.
- Q: How do I backup the program?
- A: The program is stored in non-volatile flash memory. You can also export the project file via PAC Machine Edition or use a micro-SD card for backup/restore functions.
- Q: Is it compatible with older Series 90-30 or VersaMax I/O?
- A: It can communicate with them over a network (like PROFINET or Ethernet/IP), but it cannot physically connect to their backplanes.
