The embodiment of the invention discloses a gateway configuration method, cloud equipment, a gateway and a
system, the cloud equipment is provided with a
WEB server and a
Modbus slave
station, and themethod comprises the following steps: the
WEB server receives gateway configuration information sent by a
client, and sends the gateway configuration information to the
Modbus slave
station; whereinthe gateway configuration information is remote configuration information set for the gateway to be configured by the
client through an interface configuration mode provided by a
WEB server; the
Modbus slave
station stores gateway configuration information; and when a reading instruction for the gateway configuration information sent by the Modbus
master station of the gateway to be configured isreceived, sending the gateway configuration information to the Modbus
master station according to the reading instruction. Therefore, according to the embodiment of the invention, remote configurationof the
client is realized through an interface configuration mode, the gateway configuration difficulty is reduced, the gateway can be changed and used immediately, and the real-time performance andthe
data integrity are ensured.
