Process for the production of at least one carbonylation product selected from acetic acid and methyl acetate, by carbonylating at least one carbonylatable reactant selected from methanol and reactive derivatives thereof with carbon monoxide in the presence of a catalyst. The flex cable connects the actuator to the system electronics. In accordance with the invention, a third arrangement is included for translating data received from the first system in accordance with the first protocol into data adapted for the second system in accordance with the second protocol. When the coating layer 6 is the intermetallic compound, the first metal is one type of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zr, Nb, Mo, Hf, Ta, and W and an alloy of these elements, and the second metal is Al.
