ABB PM904F 3BDH001002R0001 CPU Module

ABB PM904F 3BDH001002R0001 CPU Module

Basic Information

Model No.: PM904F 3BDH001002R0001

Type: CPU Module

Series: Freelance AC 900F Controller Series

Technical Parameters

Interface and Communication:

Supports up to 1500 I/O (input and output points) for application scenarios that handle large amounts of data.

Equipped with 4 Ethernet interfaces to provide high-speed and stable network communication capability.

800 MHz CPU clock frequency ensures fast data processing and execution capability.

48 MB controller memory to support complex control algorithms and programme operation.

Provides 4 slots for assembling communication interface module, enhancing the expandability and flexibility of the module.

Supports pluggable SD card for easy data storage and programme update.

Power Supply and External Requirements:

External 24 VDC (direct current) power supply is required.

The module itself does not have a built-in operating system and requires the appropriate operating system or firmware to be loaded during software installation.

Software version 2019 or later is recommended for configuration and management.

Application and Configuration

Application Scenario:

For demanding industrial automation and control systems, such as large production lines and automated factories.

Supports cyclic and priority-driven tasks, as well as PLC (Programmable Logic Controller) type tasks with fast cyclic cycle times.

Equipped with redundancy options for high availability to ensure stable system operation.

Configuration and Commissioning:

When configuring the module, you need to pay attention to the setting of the communication port, the selection of the device type, the selection of the connection method, and the setting of the interface parameters and the PLC station number.

If communication problems occur, you need to check the connection of the line, including whether the wiring of RS485 and RS232C is correct.

You can troubleshoot and solve the problem by online simulation and other means to ensure normal communication and stable operation of the module and the system.
