Method, apparatus, system, device and storage medium for data transmission

An electronic device, comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing instructions for execution by the at least one processor, the instructions, when executed by the at least one processor, causing the electronic device to perform operations comprising:
• determining, in response to receiving a request for application data from a client, a transmission cycle for transmitting the application data;
• sending, via a master device, first process data object information to a plurality of slave devices within a first time window of the transmission cycle, the first process data object information indicating a control operation of the master device for the plurality of slave devices;
• sending, via the master device, synchronization information to the plurality of slave devices within a second time window of the transmission cycle, to enable the plurality of slave devices to send second process data object information to the master device, the second process data object information at least indicating a response of the plurality of slave devices to the control operation;
• and
• transmitting the application data to the client to respond to the request within at least one time window of the transmission cycle other than the first time window and the second time window.

A non-transitory computer-readable storage medium having a computer program stored thereon, wherein the computer program is executable by a processor to perform operations comprising:

• determining, in response to receiving a request for application data from a client, a transmission cycle for transmitting the application data;
• sending, via a master device, first process data object information to a plurality of slave devices within a first time window of the transmission cycle, the first process data object information indicating a control operation of the master device for the plurality of slave devices;
• sending, via the master device, synchronization information to the plurality of slave devices within a second time window of the transmission cycle, to enable the plurality of slave devices to send second process data object information to the master device, the second process data object information at least indicating a response of the plurality of slave devices to the control operation;
• and
• transmitting the application data to the client to respond to the request within at least one time window of the transmission cycle other than the first time window and the second time window.
