"P.S. What is nos?"

Nos = Numbers; it's how non-English speakers refer to units, similar to how we would use the term "ea" for each, as in "I have 4 ea. flow meters..."

Took me a while to figure that out too...

Proper way You need to use the SCADAPACK or PLC, currently you got the HMI, if you using the PLC, you can add the communication card Classic way Using rs232 cable, lay the cable through control for each instrument. Use the rs 232 to rs 485 converter and connect it with the desktop.
