Can SIEMENS purple communication cable be replaced by domestic shielded cable?
PROFIBUS communications cable is a standard cable, there are many brands optional, not necessarily SIEMENS. Product quality assurance is good, whether domestic does not matter.
If the communication speed reaches 12Mbps, then the transmission distance is limited to 90 meters, then it is recommended to use imported cables.
The characteristic impedance of this cable is 150 ohms! If the communication rate is not high and the transmission distance is not far, the bus cable with characteristic impedance of 120 can be replaced.
