It is made possible to favorably perform signal transfer between a plurality of daisy-chain-connected devices. There is a communication line for performing communication between a first electronic device and a second electronic device. A data generating section generates first data to be transmitted to the first electronic device. Then, a data input section inputs the first data to a first position on the communication line. In addition, a first data suppressing section is provided at a second position on the communication line, the second position being closer to the second electronic device than the first position is, and the first data suppressing section prevents the first data from being sent to the second electronic device.

A polling method for server sensors, a polling system for server sensors, and a computer-readable memory medium. The polling method includes: when a BMC is activated, acquiring attribute information of sensors (S101); classifying the sensors according to polling cycles in the attribute information (S102); adding the sensors with the same polling cycle into a same preset data structure (S103); and polling the sensors in the preset data structure using a thread (S104). According to the method, the problem of low polling efficiency caused by polling sensors with different cycles using a single thread may be solved, and each sensor may be polled independently while minimizing influences between polling of the sensors.

A master device according to this disclosure which communicates with a plurality of slave devices to share cyclic data includes: a configuration information acquiring unit to acquire a phase difference of each of the slave devices determined based on a number of other slave devices to be relayed when the each slave device communicates with the master device; and a transmission timing determining unit to calculate a hop count from a number of other slave devices to be relayed when the each slave device communicates with the master device or another slave device based on the phase difference acquired by the configuration information acquiring unit and to determine a transmission timing for each slave device to transmit the cyclic data in such a way that communications with a same hop count are performed at a same timing by the plurality of slave devices.

In some implementations, a sensor may determine a delay latency value associated with an amount of time from completion of a set of sensor tasks to an actual time of reception of a trigger to selectively transmit or sample sensor data. The sensor may calculate a deviation of the delay latency value from a target delay latency. The sensor may transmit a data frame including an indication associated with the deviation of the delay latency value from the target delay latency.
