6ES7341-1BH02-0AE0 Siemens Simatic S7-300 CP 341 Communications Processor

Product parameters

Communication parameters: Equipped with 1 isolated 20mA (TTY) interface, using a 9-pin D-sub socket; The transmission rate range is 0.3-19.2kbit/s, and the longest communication cable distance can reach 1000 meters. Supports ASCII, 3964 (R), RK512 protocols, and can also load Modbus RTU and Data Highway DF1 protocols.

Power supply and power consumption parameters: The rated power supply is 24V DC; The maximum input current from the supply voltage L + is 100mA, and the maximum input current from the backplane bus 5V DC is 70mA. The typical power consumption is 1.6W and the maximum power consumption is 2.4W.

Connection parameters: It adopts 35mm DIN rail installation, with a protection grade of IP20, and is compatible with the modular installation architecture of S7-300. The housing is made of sturdy plastic material.

Environmental parameters: Consistent with the communication processors of the same series, the operating temperature is usually -20 ℃ to 60℃, and the storage temperature is -40 ℃ to 70℃. It can operate in an environment with a humidity of 5% to 95% and no condensation, and can adapt to the common temperature and humidity fluctuations in industrial workshops.

Function

Reduce the communication burden on the CPU: As an independent communication processor, it can undertake point-to-point communication tasks that originally required CPU processing, allowing the CPU to focus on core logic control and data operations, and avoiding excessive CPU resource occupation by communication tasks that could affect the control response speed of the entire system.

Multi-protocol compatibility and interconnection: In addition to the multiple protocols provided by the basic system, it can load mainstream industrial protocols. It can not only connect with Siemens S7 and S5 automation systems but also achieve cross-brand data interaction with industrial equipment from other manufacturers. Its compatibility covers the equipment connection requirements of most industrial scenarios.

Long-distance stable communication: Optimized for the 20mA (TTY) interface, with a communication distance of up to 1000m, it is suitable for the connection requirements of scattered equipment in large factories and workshops. There is no need to add additional signal relay equipment, reducing system construction costs, while ensuring data stability during long-distance transmission.

Convenient configuration and maintenance: The module feature configuration can be completed through the parametric tools integrated in STEP7. It also comes with a configuration software package (CD), which includes an electronic manual, parametric interface, and standard function blocks. Equipped with LED indicator lights for sending, receiving and error status, it is convenient for staff to quickly troubleshoot communication faults.

Application scenarios

Discrete manufacturing equipment linkage: In scenarios such as automotive parts processing and electronic component assembly, the S7-300 PLC is connected to on-site barcode scanners, serial printers, robot controllers and other devices to achieve real-time upload of production data and issuance of equipment control instructions, ensuring the coordinated operation of equipment in each process.

Process industry data acquisition: In process industries such as chemical engineering and food processing, the on-site sensor signal transmission modules based on 20mA (TTY) interfaces for temperature, pressure, etc. are connected to centrally transmit the scattered process parameters to the S7-300 main controller, providing data support for precise control and safety early warning of the production process.

Renovation of old industrial equipment: Many old mining machinery and metallurgical equipment adopt 20mA (TTY) communication interfaces. This module can serve as an adaptation bridge to connect these old devices to the S7-300 automation system. Without replacing the entire set of equipment, the communication upgrade of the old production line can be achieved, significantly reducing the enterprise's renovation investment.

Industrial remote terminal connection: In warehousing, logistics or outdoor industrial sites, connect the S7-300 PLC with material position sensors, equipment operation status monitoring terminals, etc. at remote locations. Through long-distance communication capabilities, remote monitoring and data management of equipment at scattered sites can be achieved.
