Model Code Breakdown
Full Model Number: 5X00790G01 OCC100
Prefix 5X00: Hardware material code segment for Ovation compact controllers. Differentiated from the coding systems of rack-mounted OCR series (5X004XX) and I/O modules (1C31XXX), it serves as an exclusive prefix designated by the manufacturer for controllers.
00790: Hardware form factor serial number, corresponding to the standard main control board hardware revision of OCC100, used to distinguish the initial generation and iteratively upgraded main control units.
G01: Hardware revision number. "G" denotes the production batch of industrial control hardware, while "01" stands for the first mass-produced mature hardware version free of hardware design flaws, which is the mainstream new original version circulating in the market.
OCC100: Official product series name. OCC stands for Ovation Compact Controller; the numeral 100 indicates the basic compact control tier, differentiating it from miniature OMC100 controllers and large rack-mounted OCR3000 / OCR1100 controllers.
Product Features
Hardware Specifications
Processor:
Industrial quad-core real-time processing chip with preemptive multi-task scheduling and configurable task priority classification.Memory: Stable industrial-grade DDR memory paired with solid-state storage media for local archiving of control programs, historical events and fault diagnostic logs.
Communication Interfaces: 4-channel Gigabit Ethernet ports, multiple RS232/RS485 serial ports and USB debug ports, compatible with fiber-optic and copper cable network wiring.
Power Supply Specifications: Supports 24 VDC industrial DC power and wide-range 85–264 VAC power supply, compatible with various on-site power circuits.
Physical Dimensions: 201 mm (W) × 216 mm (H) × 189 mm (D). Adopts a split modular base design; the main control unit and I/O base can be disassembled and installed separately.
Environmental Characteristics: Compliant with CE and RoHS industrial certifications, IP30 industrial protection rating. Resistant to dust and common electromagnetic interference, capable of non-stop operation between -20°C and 70°C.
Product Advantages
It features an integrated compact body that supports two mounting options: DIN rail mounting and standard cabinet panel mounting. Compared with traditional rack-mounted OCR series controllers, it cuts space occupation by 60%, satisfying capacity expansion demands for narrow cabinet positions in renovation projects.
Its mature and reliable redundant architecture enables bumpless switchover between primary and standby controllers. The switch process does not interrupt PID regulation, sequence logic or sequence-of-event logging, so a single-unit fault will not trigger on-site process shutdown.
Natively compatible with all Ovation I/O modules. Analog, digital, turbine-specific, excitation and equipment health monitoring modules can be directly plugged into the matching base without customized adapters. Unified management of spare parts reduces inventory costs.
The real-time scheduling cycle is flexibly adjustable, with control loop intervals ranging from 10 ms to 300 s. It supports parallel multi-task computation and can simultaneously run four types of tasks: regulatory control, sequence logic, data archiving and third-party communication, accommodating both fast loop and slow statistical computing scenarios.
Equipped with industrial wide-temperature protection, it operates stably from -20°C to 70°C. The dust-proof and anti-vibration hardware structure allows installation in local control cabinets without constant temperature control, such as those in boiler rooms, pump houses and water treatment workshops, eliminating the need for extra temperature control accessories.
Adopting a standardized TCP/IP Ethernet communication framework, it is equipped with multiple Gigabit Ethernet ports and serial communication ports. It natively supports Ovation system protocols while being compatible with third-party device interfaces including Modbus and RS485, delivering outstanding expandability.
Matched with the unified Ovation Developer Studio configuration software, a single development tool covers controller programming, I/O point lists and graphic logic. Engineers can complete full-cycle configuration and commissioning without switching software, lowering learning and maintenance barriers.

FAQ
Q: Can OCC100 (5X00790G01) be directly added to an existing OCR1100 system for capacity expansion? Is a software version upgrade required?A: It can be seamlessly integrated into the existing Ovation system. Only a matching configuration software version is required. Outdated low-version Developer Studio must be upgraded to V4.3 or higher for compatibility.
Q: How many 5X00790G01 main controllers need to be purchased for one set under redundant configuration?A: The redundant architecture requires two identical 5X00790G01 main controllers paired with a redundant base. Only one main controller is needed for a simplex non-redundant setup.
Q: The controller shows a steady red alarm light during operation. What is the troubleshooting sequence?A: Step 1: Check for fluctuations in power supply voltage;
Step 2: Verify connectivity of Ethernet communication cables;
Step 3: Access the software diagnostic interface to locate short circuits or open circuits on I/O channels;
Step 4: Reboot the main controller to eliminate program cache faults.
Q: Does the OCC100 support hot swapping of I/O modules? What operations should be completed before plugging or removing modules?A: All matching I/O modules support hot swapping. Before disassembly or installation, set the corresponding channels to manual mode in the configuration software to prevent process equipment disturbance from control loops.
Q: Will on-site valves and pumps experience sudden fluctuations during switchover between primary and standby redundant controllers?A: The factory-designed bumpless transfer mechanism enables primary and standby controllers to cache all control output values synchronously. Outputs remain constant the instant switchover occurs, resulting in no fluctuations to process equipment.
Q: How to clear full local log storage on the controller, and will this affect control operation?A: Export historical logs online via the engineer station, then clear local storage with one click. The clearing process does not interrupt real-time control logic and will not trigger system shutdown.
