ABB IMMFP02

Product Features

ABB IMMFP02 features a 32-bit microprocessor (external 16-bit bus) operating at 16 MHz, supporting high-speed data processing.

ABB IMMFP02 memory configuration includes 512 KB ROM (for storing the operating system and function libraries), 512 KB RAM (for temporary storage and configuration backups, with 347,712 bytes available), and 256 KB NVRAM (non-volatile storage for retaining configurations, with 194,752 bytes available).

ABB IMMFP02 supports Controlway high-speed redundant communication links (1 Mbaud) and module buses (83.3 kbaud), enabling peer-to-peer communication between modules.

ABB IMMFP02 has 2 general-purpose serial channels, supporting RS-232-C or 1 RS-485 + 1 RS-232-C, with a maximum rate of 19.2 kbaud.

ABB IMMFP02 has a redundant communication link (1 Mbaud), supporting hot backup and seamless switching between primary and standby modules.

ABB IMMFP02 can run control algorithms, perform real-time self-checks, and automatically enter error mode when an error is detected. Control algorithms can be edited or added, but control logic will not be executed during this process.

ABB IMMFP02 can enter error mode when hardware or configuration errors are detected, displaying error codes via LEDs. It has a built-in machine fault timer, if processor or software faults are not reset in time, the module will trigger a reset and alarm.

ABB IMMFP02 supports primary/standby redundant configurations, with the backup module continuously monitoring the primary module's status and seamlessly taking over control in the event of a primary module failure.

ABB IMMFP02 supports C, BASIC, BATCH, ladder diagrams, function codes, and user-defined functions, enabling flexible design of control strategies.

Product Using Principle

ABB IMMFP02 executes control algorithms via a microprocessor and exchanges data with I/O modules through an I/O expansion bus (8-bit parallel bus, supporting up to 64 I/O modules). The Controlway or module bus is used for communication with other intelligent modules, and DMA circuits accelerate high-speed data transmission.

When the main module is executing control logic, the backup module continuously receives the output data from the main module in real time via a redundant link and remains in a hot standby state. If the main module fails, the backup module immediately takes over control to ensure uninterrupted process operation.

In execution mode, the module continuously performs self-checks. If an error is detected, it displays the error code via an LED and enters error mode.
