Industrial Control System – Network Components

There are different network characteristics for each layer within a control system hierarchy. Network topologies across different ICS implementations vary with modern systems using Internet-based IT and enterprise integration strategies.

Control networks have merged with corporate networks to allow control engineers to monitor and control systems from outside of the control system network. The connection may also allow enterprise-level decision-makers to obtain access to process data. The following is a list [..]

ICS – Control Components

The following is a list of the major control components of an ICS:

• Control Server. The control server hosts the DCS or PLC supervisory control software that is designed to communicate with lower-level control devices. The control server accesses subordinate control modules over an ICS network.
• SCADA Server or Master Terminal Unit (MTU). The SCADA Server is the device that acts as the master in a SCADA system. Remote terminal units and [..]
