Hi, i am required to communicate with some modbus devices via tcp, i understand that i need to assign modbus addresses to these devices so i can get my data correctly. I read that the address range is from 400001 to 49999. i am just doing read only communications (i.e getting data from the devices) both analog and digital.
This is what i am doing now.
Generator running status - 400101
Engine speed - 400102
Common Fault - 400103
