AEG PCE984785 Modicon 984 Series PLC Programming & Communication Processor
- Product Introduction: This is an integrated programming and communication processor dedicated to AEG Modicon 984 series medium and large PLC systems, integrating PLC program download/upload, online debugging and multi-protocol communication functions. It acts as a communication bridge between the PLC system and upper-level monitoring equipment (SCADA, HMI), programming equipment and lower-level field devices, and is a core functional module for realizing the networking, remote monitoring and program maintenance of the 984 series PLC system.
- Technical Specifications:
- Programming Interface: RS-232 (DB9), support AEG Modicon 984 dedicated programming protocol, transmission rate up to 115200 bps.
- Fieldbus Interfaces: Profibus-DP V1, Modbus TCP/IP, RS-485 (Modbus RTU), 3 independent communication ports for simultaneous multi-protocol communication.
- Processor: 16-bit industrial RISC processor, operating frequency 80 MHz, dedicated to communication data processing and protocol conversion.
- Data Buffer: 256 KB dual-port RAM, for real-time caching of communication data, preventing data loss during high-speed transmission.
- Connection Capacity: Profibus-DP up to 32 slave stations, Modbus TCP/IP up to 16 concurrent TCP connections, RS-485 up to 248 slave nodes.
Detailed content
-
- Power Supply: 24 VDC from PLC backplane bus, power consumption ≤5 W.
- Operating Temperature: -20°C to +60°C; Storage Temperature: -40°C to +85°C.
- Protection Rating: IP20; Dimensions: 120mm × 160mm × 55mm (W×H×D); Weight: 0.6 kg.
- Protocol Conversion Latency: ≤1 ms between different protocols, ensuring real-time data transmission.
- Functional Features:
- Integrated programming and multi-protocol communication functions replace the traditional separate programming module and communication module, reducing the occupation of PLC chassis slots and system configuration cost.
- Three independent communication ports support simultaneous data transmission of different protocols, realizing the seamless connection between the PLC system and upper-level SCADA, fieldbus slave stations and local programming equipment without mutual interference.
- High-speed dedicated RISC processor and large-capacity dual-port RAM ensure high-speed and stable data processing and transmission, adapting to the high real-time requirements of large-scale industrial control systems.
- Support online program download/upload and real-time debugging of the PLC system through the RS-232 port, and the debugging process does not affect the normal operation of the PLC’s on-site control program.
- Built-in Profibus-DP master station function, which can directly connect a variety of Profibus-DP field devices such as frequency converters, servo drivers and intelligent sensors, realizing the integration of the PLC system and the field device layer.
- Modbus TCP/IP port supports remote access and control of the PLC system through the industrial Ethernet, realizing the remote monitoring, fault diagnosis and program maintenance of the control system.
- Built-in communication fault self-healing function, automatic reconnection after communication interruption, and data buffer function to ensure the integrity of the interrupted data.
- Each communication port is equipped with independent LED status indicators (link, data transmission, fault), realizing visual monitoring of the communication status of each port for quick troubleshooting of communication faults.
- Fully compatible with AEG Modicon 984 series PLC backplane bus, plug-and-play, and the communication parameters can be configured online through the PLC programming software, with simple operation.
- Application Scenarios: It is a standard configuration module for AEG Modicon 984 series PLC systems, widely used in large-scale industrial control projects such as oil refinery full-process control, steel mill smelting automation, intelligent factory production line central control, and municipal large-scale water treatment system control. It is the core module for realizing the networking of the 984 series PLC system with upper-level monitoring systems, fieldbus devices and programming equipment, and is also applied in the remote monitoring and maintenance of industrial control systems in scattered locations such as wind power plants and substation automation systems.
