We present the results of two BeppoSAX broad band (0.1-200 keV) observations of the Z-source GX 340+0 comparing our results to those of a previous observation of the source. From the color-color diagram we selected three zones and extracted the source energy spectrum from each zone. We find that the model, composed by a blackbody plus a Comptonized component, absorbed by an equivalent hydrogen column of similar to 6 x 10(22) cm(-2), well fits the spectra in the energy range below 30 keV. At higher energies a power law component with photon index of 2.5 is observed. The associated flux decreases going from the horizontal branch to the flaring branch of the Z-track.
