Abstract
A method and device or monitoring parameters in a process reduces power consumption and bandwidth requirements in the transmission of the monitored parameter to for example, a monitoring application. In particular, new monitoring parameter values are only transmitted if the difference between a measured or calculated parameter value and the most recently transmitted value exceeds a limit, since the last communication of the parameter or if the time since the last communication of the parameter exceeds a preset refresh period. The determination as to whether to transmit the parameter can be applied to engineering unit values or raw values.
