Basic Product Information
Product Classification: Base Unit (core hardware for AC 800F controllers)
ABB Type Designation: PM802F
Product ID: 3BDH000002R1
Key Function: Serves as the backplane for mounting fieldbus modules (e.g., PROFIBUS, Ethernet) and power supplies; provides processing, memory, and communication capabilities for industrial control logic execution.
Operating System Requirement: No pre-installed operating system—must be loaded during software installation via ABB’s Control Builder F tool.
Mandatory Software: Control Builder F V7.1SP2a or higher (for configuration, operating system deployment, and system integration).
Special Component: Includes a dedicated Contact Ledge RW 855F (for mechanical stability and module alignment).

Core Specifications
1.Hardware & Processing Capabilities
CPU: Intel® 80960HT25/75 32-bit RISC Super Scalar processor, delivering up to 150 MIPS (millions of instructions per second) for fast control loop execution.
Memory Configuration:
RAM: 4 MB static read/write memory (battery-buffered to preserve data during power loss).
Flash EPROM: 4 MB (32-bit word length) for storing firmware and system software.
EEPROM: 16 kbit serial EEPROM for non-volatile storage of configuration parameters (no battery required).
Cache: 16 KB internal CPU cache to optimize data access and processing speed.
Error Handling: RAM with Error Detection and Correction (EDC) to enhance data integrity in harsh industrial environments.
2.Module Expansion & Connectivity
Slot Configuration:
4 slots for fieldbus modules (supports PROFIBUS-DP, Ethernet, CAN, and FOUNDATION Fieldbus modules such as FI 830F, EI 813F).
2 slots for Ethernet communication modules (32-bit data bus, 10 Mbps transmission rate) to enable connectivity to the control network.
Backplane Functionality: Provides power distribution and data transfer between mounted modules; supports hot-swapping of fieldbus modules (removal/insertion during operation without system shutdown).
3.Power Requirements
Compatible Power Supplies:
SA 811F (115/230 V AC input, 5 V DC/5.5 A + 3.3 V DC/6.5 A output).
SD 812F (24 V DC input, 5 V DC/5.5 A + 3.3 V DC/6.5 A output, redundant input supported).
Power Consumption: Maximum 6.3 W (base unit only, excluding power draw from mounted modules); varies with CPU load and cycle time.
4.Environmental & Mechanical Specifications
Operating Temperature Range: 0 °C to 60 °C (32 °F to 140 °F); internal module temperature monitored to prevent overheating.
Storage Temperature Range: -25 °C to +85 °C (-13 °F to 185 °F).
Relative Humidity: ≤ 95% RH (non-condensing, annual average); ≤ 80% RH for continuous operation.
Dimensions (W × H × D): 239 mm × 202 mm × 164 mm (9.4 inches × 8 inches × 6.5 inches) — compatible with standard 19-inch industrial racks.
Weight: 1.6 kg (3.3 lbs) for the base unit; up to 5 kg (11 lbs) when fully assembled with modules and power supplies.
Mounting: DIN rail (EN 50022) or wall mounting (with optional accessories like RW 856F).
5.Redundancy & Reliability
Redundancy Support: Can be configured in a redundant controller setup (paired with a second PM802F) for high availability; uses a dedicated Ethernet link to synchronize data between primary and secondary units, enabling millisecond-level failover.
Battery Backup: RAM data is buffered by an external battery (e.g., SB 808F) — provides ≥ 1.5 years of data retention at 25 °C (77 °F); low-battery warning issued ~2 weeks before critical charge loss.
Watchdog Timer: Built-in watchdog function to detect system anomalies and trigger reset/recovery procedures if needed.
Key Application & Functional Notes
System Integration: Works seamlessly with ABB’s Freelance 800F ecosystem, including DigiVis operator stations (for monitoring) and S800/S900 remote I/Os (for field signal acquisition). It communicates with other controllers (AC 700F/AC 800F) via Ethernet-based control networks (TCP/IP, UDP).
Configuration Flexibility: Control Builder F enables programming in IEC 61131-3 languages (FBD, LD, ST, SFC, IL) and supports integration of fieldbus devices (PROFIBUS-DP slaves, HART instruments) via GSD files or DTMs (Device Type Managers).
Diagnostics: Provides real-time diagnostics for modules, power supplies, and communication links; status is visible via front-panel LEDs and can be monitored remotely via the DCS.
Hot-Swapping: Mounted fieldbus modules (e.g., EI 813F, FI 830F) can be hot-swapped— the system automatically detects new modules and loads required configurations, minimizing downtime.
