Supervision And Data Acquisition Tools

General DescriptionThe Arian instruments send continuouslly data (e.g. temperatures, counts, positions of valves) to a PC by means of a single wire pair across the plant.Having in the PC a continuous historical data registry makes possible to generate automatically production reports.Derived benefits will be improvements in the productivity, cost reduction and a superior quality control.

How it worksEach instrument haves the optional RS485 isolated output card installed.The RS485 bus is a low cost twisted single wire pair that connects the devices thru the plant and ends in the ISO485 interface module that converts RS485 in to galvanically isolated RS232.Finally the RS232 connects to a PC serial communications port.

What do you need to start up communicating

Each of the devices must have installed comunications option.

One ISO485 interface device for isolating and controlling the RS485 bus from the PC RS232 port
