roghenr Posted January 20, 2023 Report Share Posted January 20, 2023 Good Morning. I need help, I'm using plvc vision 130 and I want to read modbus data from a yaskawa inverter, which I haven't been successful with. I was successful in: inverter on/off #yaskawa address 0001H enter frequency #yaskawa address 0002H Unsuccessful in: read frequency #yaskawa address 0024H read inverter status #yaskawa address 0020H I would like to see in the ihm the value of the bits to use in the application Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted January 20, 2023 MVP 2023 Report Share Posted January 20, 2023 Hi, in your read command used only 1bit vector length. Yaskawa operate with 16bit vector that must be transmitted to MI Vector. Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 20, 2023 MVP 2023 Report Share Posted January 20, 2023 You've also got your RHR status (MI 52) at one address after your destination (MI 51) so you're going to stomp on yourself when you read a vector larger than one. Set your status address much higher, like at MI 100. Joe T. Link to comment Share on other sites More sharing options...
