The objective of this paper is to compare the performance of the workbenches developed in the client-server architecture for internet telecontrol systems using embedded systems as a data acquisition card, with the purpose of determining which of the embedded systems used ( Myrio, CompactRio, Arduino Nano Board) has a better performance considering the transmission, reception and execution times involved in the communication between the controlled system and the controller system. To achieve this objective, a telecontrol client-server communication system was implemented to apply a proportional control action to an unstable system of first order emulated with operational amplifiers and the times involved were measured using an embedded computing system (Raspberry PI) . This in order to characterize the times involved in the telecontrol process using descriptive measures like the ordinary first-order moment (arithmetic average) and the central second-order moment (variance or dispersion) and to determine from the analysis of processing times which had the best result.
