Function

Multi-role PROFIBUS communication: It can flexibly switch to serve as a PROFIBUS DP master station or slave station to access the bus, adapting to different industrial network topology requirements and meeting the data interaction architecture design between devices.

Multi-type compatible communication: It is S5 compatible and supports both PG/OP communication and S7 communication. It can be adapted to both new and old industrial control systems, ensuring smooth data transmission between programming devices, operation terminals and S7-300 PLCS.

Open communication extension: In an open communication scenario, up to 16 connections can be established through the sending/receiving module, with each connection having a maximum valid data volume of 240 bytes, which can meet the data interaction requirements with other industrial devices that support open communication protocols.

Concurrent operation of multiple protocols: When running multiple protocols, the maximum effective connection number is 32 without DP function and 28 with DP function. It can handle multiple communication tasks simultaneously and meet the multi-device collaborative communication requirements in complex industrial scenarios.

Application scenarios

In process industry control scenarios: In process plants such as petrochemicals and chemical raw material production, it is used for optical fiber communication between S7-300 PLC and on-site sensors, actuators, valve controllers and other equipment. Optical fiber transmission has strong resistance to electromagnetic interference and is suitable for the complex electromagnetic environment brought about by the dense distribution of motors, frequency converters and other equipment in factories, ensuring the stability of production parameter collection and control instruction transmission.

Manufacturing automation production line Such as automotive parts production lines, electronic component assembly lines, etc., can be connected to the PROFIBUS DP network to achieve data interaction between the S7-300 PLC and the automated equipment and testing instruments at each workstation, completing functions such as production cycle control and uploading of product quality inspection data. At the same time, it is compatible with the old S5 series equipment. Reduce the cost of production line renovation and upgrading.

Explosion-proof and special industrial environments: This module complies with the relevant explosion-proof standards GB3836.1 and GB3836.8, and is suitable for industrial scenarios with explosion-proof requirements, such as ground auxiliary control systems in coal mining and natural gas processing stations. It avoids the risk of electrical sparks through optical fiber communication while ensuring communication reliability.

Integration of small and medium-sized industrial control systems: In small and medium-sized production lines such as food processing and beverage filling, it is used to build a distributed control system based on S7-300, achieving communication between the central control room and scattered field equipment, taking into account communication efficiency and cost, and meeting the automation control requirements of small and medium-sized production.
