Dear all,
I'm a little bit new in this feild, so i need ur advice for starting run a project for SCADA gas project.

from my basic research on the web and some books;
there are two basic modes of capture of input data which maybe used by the central processing facility of the SCADA:
- Scheduled capture, whereby the local units are polled on a regular basis and all input data are transferred; or
- change of state capture,whereby only input data which have changed are transferred.
anothe question; for the I/O network there are two options:
- Either all RTU are connected on the PLC remote I/O communication network and the SCADA servers connected via another link to the PLC that as that as the role of interface;
- or all the RTU and PLC are directly connected to the SCADA servers via the I/O communication network
Your help is highly appreciated.
