Problems with Hollyland’s communication equipment?
Thread Content
There is an IO station where GE optical transceivers based on the ProfiBus-DP protocol are used for communication. Since the wires of the DP protocol are thin and prone to breaking, there was once a case of a wire breakage; therefore, we wanted to replace them with Siemens’ DP optical transceivers. However, the technical engineers from Lihai said that they might not work properly, and they would not be responsible if anything went wrong. We took the opportunity during a downtime to make the replacement, and found that both the input and output functions were working normally. The Siemens DP connectors are very reliable, and after more than 4 years of use, no problems have occurred. I hope that the technical and product professionals in domestic manufacturers can develop better and faster, so as not to put users at risk.
There are always some issues with communication with Hollyland’s systems; I hope this can be improved.
The optical transceiver doesn’t matter much; it’s just a communication medium.
