Hello:
I began working a week ago, and now I have problems with a Big Project. It is about metering every cost center of a big refinery. The problem is that we should use our equipment (with Modbus RTU protocol over an RS485 network) to get the data, there is a big distance between every center and the Central Unit, and more than 100 meters. We are considering the fact of use repeaters (for RS485) and probably an optic fiber line to the longer distances. My question is: Is it possible to connect twisted pair, optic fiber and a lot of meters in a RS485 network? We have another line of meters that accept LonTalk protocol, Should we change our network to get more reliable data (what about the costs)?
And, what about the distance and the amount of data transmitted? Please I need comments.
Thanks
Boris
