Product Overview
The GE IC693CPU311Z Series 90-30 5-Slot Baseplate with Embedded CPU combines the rack/backplane structure and PLC processing function in a compact Series 90-30 control configuration. Instead of requiring a separate CPU module to occupy one of the rack positions, the CPU is integrated into the baseplate assembly.
This arrangement is useful where a small PLC system needs local processing with a limited number of installed modules. The baseplate provides the physical mounting and electrical interconnection for compatible Series 90-30 modules, while the embedded CPU executes the application program and manages the control system.
A typical installation can use the available module positions for I/O or other system components while retaining the CPU function within the baseplate. This makes the IC693CPU311Z particularly suitable for compact machine-control panels and legacy Series 90-30 installations with relatively small I/O requirements.

Working Principle
The IC693CPU311Z combines two functions that are normally considered separately in a modular PLC: the baseplate provides module interconnection, while the embedded CPU performs program execution and control processing.
Input information from connected Series 90-30 input modules is transferred through the baseplate to the embedded CPU. The CPU executes the user application and determines the required output states. Output modules then transfer those commands to the connected field equipment.
A simplified signal and control path is:
Field Devices → Series 90-30 Input Modules → IC693CPU311Z Embedded CPU → PLC Logic → Output Modules → Field Equipment
Because the CPU is integrated into the baseplate, troubleshooting should consider both the processing function and the rack connection. If multiple modules exhibit communication or recognition problems, the baseplate and system power path should be checked rather than assuming that an individual I/O module is defective.
Role in a Series 90-30 Control Architecture
| System Element | Function |
|---|---|
| Field Sensors | Provide machine and process input conditions |
| Series 90-30 Input Modules | Acquire discrete or analog field information |
| IC693CPU311Z | Provides embedded CPU processing and module interconnection |
| PLC Application Program | Executes sequencing, interlocks, and control logic |
| Series 90-30 Output Modules | Convert CPU commands into field-side output actions |
| Field Actuators | Perform the commanded machine or process functions |
| Power Supply | Provides the required electrical power for the PLC system |
The IC693CPU311Z serves as the central processing element in the compact rack:
Field Inputs → Input Modules → IC693CPU311Z → Control Logic → Output Modules → Actuators
The five-slot baseplate determines the available physical module positions, so the overall system should be planned around the required I/O and other compatible modules.
Industrial Applications

Installation and Maintenance
- Verify System Architecture
Confirm that the application is intended for a Series 90-30 baseplate with an embedded CPU before installation. - Check Module Capacity
Plan the five available module positions according to the required I/O and system components. - Inspect the Baseplate
Check the housing, mounting points, connectors, and backplane area for physical damage before installation. - Verify Power Connections
Confirm that the associated PLC power arrangement is correctly installed before energizing the system. - Check Module Seating
Make sure installed I/O and other modules are properly seated and mechanically secured. - Inspect Backplane Connections
If multiple modules fail to operate or are not recognized, inspect the common backplane connection before replacing individual modules. - Review CPU Status
Check the embedded CPU operating status and diagnostic information when the PLC does not execute the expected application. - Verify Program Configuration
Confirm that the application program and hardware configuration correspond to the installed system. - Inspect Field Wiring
When individual I/O functions fail, check field wiring and connected devices before assuming a CPU or baseplate fault. - Maintain Rack Documentation
Record the module occupying each available position to simplify future maintenance and replacement. - Follow Safe Maintenance Procedures
De-energize and isolate the appropriate equipment according to site procedures before working on the PLC hardware. - Perform Functional Testing
After replacement or maintenance, verify CPU operation, module recognition, I/O response, and the complete machine-control sequence.

Technical FAQs
What is the main difference between the IC693CPU311Z and a standard Series 90-30 CPU module?
The IC693CPU311Z combines the CPU function with the baseplate rather than using a separate CPU module. This creates a compact control architecture in which the processing function is integrated into the rack assembly.
How should the five available slots be planned?
The available positions should be allocated according to the required input, output, and other compatible Series 90-30 modules. Because the CPU is integrated into the baseplate, the application should be planned around the remaining available module capacity rather than reserving a separate slot for a conventional CPU module.
What should be checked if several I/O modules stop communicating with the CPU?
Check the common system elements first, including power, module seating, baseplate/backplane connections, and CPU operating status. If several modules are affected simultaneously, a common rack or system-level issue is more relevant to investigate than immediately replacing individual I/O modules.
Can the IC693CPU311Z be used for applications requiring a large amount of I/O?
The baseplate provides five module positions, so the available local capacity is inherently limited compared with larger Series 90-30 configurations. Applications should therefore be evaluated based on the required I/O count, communication requirements, expansion architecture, and available rack capacity.
