The communication distance of the profibus bus is different depending on the baud rate. If the maximum speed is 12M, it can only be about 100 meters. 1.5M can reach 800 meters. The farthest distance without a repeater is 1000m. And the baud rate should be set to the lowest. If you are lucky, the situation is good, and the original profibus cable is used, it is not impossible to distance it. But this does not necessarily work stably. Therefore, the construction on site is best carried out in strict accordance with the standard, less than or equal to 1000m.
