9. PROFview XL User Manual PROFview XL 3 Description of Functions and Measuring Principle For this measurement to function correctly it is merely necessary to set the baud rate of the PROFIBUS seg ment via the PBT application software and to connect the PBT to the plant Subsequently the device will de termine the address of a master automatically and starts measuring the bus cycle time Each time the token is passed on the time measurement is stopped and restarted at the same time The resolution of the time measurement is approx 100 us The longest bus cycle time which can be detected is one second 3 3 3 Illegal frames The counter for illegal frames is like the bus cycle time a real time monitoring function The background to this measurement is to be able to perform a protocol check of all frames transferred on the bus If a logic er ror is found in a frame this counter is incremented by one As a rule the counter of this display should always show 0 If on the other hand errors occur occasionally or even frequently this is due less to non conforming PROFIBUS circuits of the PROFIBUS stations but rather to problems with the physical bus characteristics and the resulting transmission errors But station ad dresses assigned twice duplicate addressing can also cause errors of this kind The illegal frame counter of the PBT counts max 50 000 illegal frames A frame is detected as illegal if at least one of the followi
