Abstract
This paper presents an implementation of the support for data transfer with diagnostic data within an IoT system that includes the fog device and cloud. Data transfer within the device is performed using the CAN bus, following the CANOpen protocol, while the data transfer to the cloud follows the HTTP protocol. During the data transfer, a deficiency is noticed if the time constraint is fixed. To overcome this deficiency, the calculation of the time constraint based on the bandwidth and file size is implemented. The paper includes the analysis of the time constraint calculation results.
