We use USC- B5-T42 for our projects but in this instance my question is just regarding modbus as I cant do anything with the macines that we have bought in. The energy meters are independant of the machine we just put the CT on the power in cable.
Has anyone attempted to convert modbus RTU to TCP using C# or any other PC based method?
We are about to purchase 40 energy meters that use modbus RTU for each of the machines on the shop floor, we are told by the saleman that we have to purchase modbus RTU to TCP converters to get the data on the network. At $200 each multiplied by 40, i wondering if I can get around having to buy them. Each machine has a normal PC connected to it, so I'm thinking I can send the RTU to the PC via a serial port then covert to TCP to get the data on the network.
I usually work with PID loops and tunning it manually. This time i want to try the autotune feature but i'm facing some troubles with the autotunedone bit in "PID Config" struct. This bit when autotune is completed is always ON and the help file says "Reset by user"... Well this bit is not possible write on it cause is a reading bit. So could you tell me how to reset this bit after autotune is done? If you start the autotune process again the autotunedone bit is reset by itself, but i want to reset it before start autotune process once again.
