Working principle

DSPC172 operates based on a closed-loop control architecture of "signal acquisition algorithm processing instruction output state feedback". The core process is as follows:

Data acquisition layer: Receive digital/analog signals (such as temperature, pressure, motor speed) from sensors and transmitters through S800 I/O modules, and transmit them to the CPU core through RS-485/Ethernet interfaces.

Core layer processing: 32-bit RISC processor is responsible for logical operations, DSP unit specializes in signal filtering and mathematical modeling, FPGA implements high-speed timing control, and the three work together to execute preset control algorithms (such as motor variable frequency speed regulation logic).

Instruction execution layer: The processing results are converted into switch/analog output signals, which drive actuators (such as solenoid valves and servo motors) through I/O ports, and upload real-time data to the monitoring system.

Redundancy and diagnostic mechanism: Dual port real-time monitoring of communication links, built-in self-test program continuously verifies memory and I/O status, triggers alarms and switches to backup channels in case of faults, ensuring control continuity.

Precautions

Installation specifications:

At least 50mm of heat dissipation space should be reserved to avoid direct contact with high-power devices, and the installation torque should be controlled within the range of 0.5-0.8N · m.

The communication cable needs to use shielded twisted pair, with a distance of not less than 30cm from the power line, and Ethernet redundant links need to be equipped with independent switch ports.

Operation and maintenance:

Before the first startup, the firmware version needs to be verified through ABB configuration software to ensure compatibility with the I/O module (recommended version V5.2 and above).

Regularly backup user programs in Flash, and it is recommended to perform a comprehensive self check every 3 months to investigate interface looseness and component aging issues.

Security protection:

The power supply system needs to be equipped with a 24V DC redundant power supply, and surge protectors (SPDs) should be installed to cope with grid fluctuations, with a grounding resistance of ≤ 4 Ω.

Firmware upgrade requires disconnecting the load circuit, and module insertion and removal are prohibited while in operation. Maintenance must be carried out by ABB certified engineers.
