Embodiment 1

[0044] See figure 1 , figure 1 This is an implementation flowchart of a method for implementing a PROFINET industrial Ethernet gateway in an embodiment of the present invention, and the method may include the following steps:

[0045] S101: The master station sends a slave station name query request to each slave station through the DCP search protocol.

[0046] After the master station and the slave station are powered on, they are initialized first. The initialization work can include memory allocation, interrupt initialization, hardware board driver installation, network card driver installation, initializing MAC address interface, etc., and initialize the PROFINET protocol stack. After the initialization is completed, the master station can send slave station name query requests to each slave station through the DCP search protocol. The slave station can be any slave station connected to the master station. The master station can directly send a slave station name query request...

[0057] See image 3 , image 3 This is another implementation flow chart of the implementation method of the PROFINET industrial Ethernet gateway in the embodiment of the present invention. The method may include the following steps:

[0058] S301: The master station sends a slave station name query request to each directly connected slave station and each slave station connected through an intermediate slave station through the DCP search protocol.

[0059] Among them, the master station uses the LLDP link discovery protocol to exchange device information through the adjacent slave stations, and establishes connections between the slave stations connected through the intermediate slave stations.

[0060] The master station and the slave station may be directly connected, or may be connected through an intermediate slave station. For the slave station connected with the master station through an intermediate slave station, the LLDP link discovery protocol can be used between the slave...

[0074] See Figure 4 , Figure 4 This is another implementation flow chart of the implementation method of the PROFINET industrial Ethernet gateway in the embodiment of the present invention. The method may include the following steps:

[0075] S401: The master station sends a slave station name query request to each directly connected slave station and each slave station connected through an intermediate slave station through the DCP search protocol.

[0076] Among them, the master station uses the LLDP link discovery protocol to exchange device information through the adjacent slave stations, and establishes connections between the slave stations connected through the intermediate slave stations.

[0077] S402: Each slave station returns its own slave station name to the master station.

[0078] S403: The master station performs address resolution on each slave station name through the ARP protocol, and obtains the address resolution result of each slave station.

[0079] S404: The ma...

Abstract

The invention discloses a method for realizing PROFINET industrial Ethernet gateway. The method comprises the following steps: a master station respectively sends a slave station name inquiry requestto each slave station through a DCP search protocol; the master station sends the slave station name inquiry request to each slave station. Receiving a master station name returned by each slave station. The address resolution of each slave station is performed by ARP protocol, and the address resolution results of each slave station are obtained. According to the address resolution result of eachslave station, IP address parameters are assigned to the corresponding slave station to establish a gateway with each slave station. The technical proposal provided by the embodiment of the inventiondoes not require an external PROFINET protocol special chip, solves the problem of complex maintenance and replacement procedures of the PROFINET protocol special chip, and reduces the cost. The invention also discloses an implementation device, a device and a storage medium of a PROFINET industrial Ethernet gateway, which have corresponding technical effects.

Description

Technical field [0001] The present invention relates to the technical field of realization of industrial control communication gateways, in particular to a realization method, device, equipment and computer-readable storage medium of a PROFINET industrial Ethernet gateway. Background technique [0002] PROFINET is an automation bus standard based on industrial Ethernet technology and is fully compatible with standard Ethernet. It is increasingly being used in field industrial control. Due to the long-term coexistence of a variety of mainstream field buses, different types of control networks are connected together through a gateway to realize the communication between the master station and the slave stations. [0003] At present, the realization of PROFINET gateway products on the market mostly adopts PROFINET protocol dedicated chips, which is costly, and the maintenance and replacement procedures of PROFINET protocol dedicated chips are complicated. [0004] In summary, how to ef...
