Abstract
A method for detecting and identifying items of equipment communicating according to a Modbus communication protocol, connected by means of a first communication network of Ethernet type and by means of at least one second communication network, the first and the second communication network being linked by a communication gateway. A communication controller implementing such a method also is disclosed.
Claims19
Method A method implemented in a communication controller connected, by means of a first communication network of Ethernet type, to one or more first items of equipment communicating according to an IP protocol, said method being intended:
- to detect and to identify the first item or items of equipment communicating according to a Modbus TCP/IP communication protocol, and
- to detect and identify second items of equipment connected to one another by means of at least one second communication network of serial Modbus type, said second communication network being connected to the first communication network by means of a communication gateway,
- said method comprising:
- searching for all of the first items of equipment connected to the first communication network and communicating according to an IP protocol,
- searching for the first item or items of equipment communicating according to a Modbus TCP/IP communication protocol,
- identifying at least one communication gateway from among the first item or items of equipment, and
- searching for and identifying the second item or items of equipment when at least one communication gateway is identified.
