Hi,
There are two separate DCS systems (1 & 2) at our site. Due to the legacy design of both systems, it is not possible to implement OPC connectivity between the two. The distance between the two DCS systems is also quite huge.
I want to transfer some 4-20mA analog signals from DCS System 1 to DCS system 2. It will be quite simple to lay down a standard instrument multi-pair cable between the two but there are limitations like EMI, cable length, high costs, etc.
Due to these factors, I have another idea. I want to convert these 4-20mA signals from DCS system 1 into fibre optic media, lay a fibre cable between the two DCS and finally, convert it back to 4-20mA at the other DCS.
I want to know if this is really possible. Has somebody implemented this type of topology at his/her site? Please guide me in this.
