CitectSCADA can communicate with an array of I/O Devices, including PLCs (Programmable Logic Controllers), loop controllers, and distributed control systems (DCS).
The I/O Devices may be local (directly connected to an I/O Server) or remote (connected to CitectSCADA via an intermediate communications means like a phone line).
Drivers enable communication with devices via a number of communication protocols (including Ethernet, TCP/IP, and Serial). The driver defines the specific project settings necessary for CitectSCADA to communicate with a particular device. This includes information about:
