A method for use in an automated wireless industrial system comprising a device configured to act as a control node and at least one field level device, wherein the method comprises: issuing a control communication; inserting at least one time delay (tk) to the control communication; noting the communication time (TCL) for the communication; comparing the time for communication (TCL) to an expected time for communication (TR); and determining if any of the at least one time delay (tk) should be adapted, and if so, adapting at least that time delay.

A computer program and method for data communication in a network having a plurality of network nodes, via which method data packets are to be transferred between communication partners over protected connections, wherein the data packets originate from at least two different sending communication partners, or senders, and wherein the sending frequencies of at least two senders, at which the senders send data packets that are to be transferred over a protected connection, differ from one another, and the sending frequencies and/or variables representing same being taken into account when finding a path for the transfer of the data packets of at least one protected connection.

To obtain a plant-monitoring autonomous control system which performs autonomous distributed control without using an advanced calculation processing unit such as a CPU. A plant-monitoring autonomous control system is provided with a control network which mutually connects: input nodes for receiving an input signal from a control target apparatus and transmitting the input signal to the control network; a calculation node having calculation circuits, and for transmitting, to the control network, a result obtained by performing calculation processing on data received from the input node; and an output node for outputting, to the control target apparatus, data received from the calculation node.

A method for use in an automated wireless industrial system comprising a device (100, 210,220) configured to act as a control node and at least one field level device (100), 230), wherein the method comprises: issuing a control communication (510); inserting at least one5 time delay (tk) to the control communication (520); noting (530) the communication time (TCL) for the communication; comparing (540) the time for communication (TCL) to an expected time for communication (TR); and determining (550) if any of the at least one time delay (tk) should be adapted, and if so, adapting at least that time delay (560).
