Modbus TCP/IP Write registers - dezanvu - 22-03-2024 Greetings, I am trying to write some registers: 400YY on a device x.x.1.55 port:1500 Configuration: IO modbus: [TOPIC A] ID:1 | IP:x.x.1.55 [enabled] In order to be able to read from the device i added this: Advanced parameters (IOSrvData): IpMbsSrvPort:1500 TcpPort:1500 and some tags...: tag1 30001 tag2 30002 tag3 40001 tag4 40002 Reading from device is ok. How should i write the 40000 registers to the device x.x.1.55 ? I tried to manually update the values from tag values and click apply. Tried simple scripts like tag3@ = 5 Also tried with ModbusForceFunction06 = 1 (menu Edit COM cfg) But the new values are not received by the device. Any ideas will be usefull! RE: Modbus TCP/IP Write registers - simon - 25-03-2024 Hi, Indeed you have tried all easy options... The best to investigate that is to register a support ticket on the HMS ticketing platform and we will probably ask you an access to your test device via Talk2m to troubleshoot it live. RE: Modbus TCP/IP Write registers - dezanvu - 26-03-2024 Ok solved. I had to add "ModbusForceFunction06 = 1" to Advanced parameters (IOSrvData). |
