Abstract

The invention discloses an industrial field bus system. The industrial field bus system comprises a PLC, gateways, I/O modules and field sensors. The PLC is connected with the gateways through industrial field buses, the gateways are connected with the I/O modules through internal buses, the I/O modules are connected with the field sensors, the field sensors are used for collecting data of an industrial field, each gateway is connected with a plurality of the I/O modules, and the I/O modules which are connected with the same gateway and belong to the same branch circuit are in multi-level connection. The industrial field bus system can realize multi-level connection of the I/O modules, and each I/O module has the cascading function. The structure of the industrial field bus system is simplified, the use cost of equipment and the use cost of cables are lowered, therefore, the purpose that function coverage of the large industrial field can be realized by using only one PLC, and the use requirements of users can be met.
