UniCloud: the end-to-end IIoT Platform for Unitronics Controllers

If the energy meters Modbus RTU ports are RS485 and they are addressable you can daisy-chain them all together and run them into one Ethernet converter. What is the make and model number of the energy meter? Joe T.

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.

What PLC are you using?

Thanks for the help guys. I have this one figured out. The programmer is off sick for the next few days, so when he gets back, it will be all better.

Hi, 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.
