Gateway, system and method of operating a gateway

A system comprising a valve arrangement as well as a gateway for retrieving telemetry data from a field device and for transmitting the retrieved telemetry data to a cloud server, wherein the gateway comprises a cloud communication component which is designed to specify periodic request points in time at which an internal gateway request for a current variable value of a variable of the telemetry data is to be made, and to transmit the current variable value which is provided in response to the internal gateway request to the cloud server, as well as a field device communication component which is designed to carry out a variable retrieval of the current variable value from the field device at periodic retrieval points in time and to make the current variable value which is received with the variable retrieval available to the cloud communication component in response to the gateway request, wherein the gateway is designed to set the phase of the periodic retrieval points in time relative to the periodic request points in time such that the respective current variable value which the field device communication component provides to the cloud communication component in response to the respective gateway request has already been retrieved from the field device at the request point in time of this gateway request and is present in the field device communication component, wherein the gateway is designed to retrieve the telemetry data from and/or via the valve arrangement.
