Hello Ganesan_K, What kind of cable do you use? Do you use Bus connectors or you connect cable directly to terminals of SIMOCODE? Poor and unclassified cables would give a big resistance andloose termination of PROFIBUS wires would also cause the same. I've seen customers using repeaters from PROCENTEC to solve similar issues but this solution can be quite expensive. The cost depends on how many SIMCODE's you will connect to a single spur line. Best regards, H-H |

Hello Ganesan_K, How do you measure this voltage? Do you have 220VAC or 24VDC powered SIMOCODE? If you have 24VDC powered SIMOCODE, do you connect all M- together? Did you make sure you have groundedall SIMOCODEs to the same reference? How do you distribute your SIMOCODEs, I mean how many segments/repeaters do you have for the 50 slaves? Do you have the same problem in all segments? Do you use any bus analyzer?If not, I recommend to use one. Also make sure your installation was done according to PROFIBUS installation guidelines. Best regards. H-H |
