Abstract

The invention discloses a bus state diagnosis extension system, which comprises an I / O (Input / Output) module for acquiring data of field equipment to form to-be-diagnosed data and transmitting the to-be-diagnosed data to a coupler; the coupler is used for sending a to-be-diagnosed data acquisition instruction to the I / O module, receiving to-be-diagnosed data sent by the I / O module, integrating and packaging the to-be-diagnosed data and own to-be-diagnosed data to obtain a data packet, and transmitting the data packet to the diagnosis module; the diagnosis module is used for receiving the data packet transmitted by the coupler, analyzing and processing the data packet, and transmitting analyzed diagnosis information to the coupler; and the PLC is used for reading the data area corresponding to the diagnosis module in the coupler through the industrial bus so as to obtain the required diagnosis information. The system is provided with the diagnosis module, so that the compatibility of the system is enhanced, a user can easily access a new function on the basis of keeping the original function, and extra cost and time loss caused by version incompatibility are avoided.
