SANS 410 Latest Update with Verified Solutions Industrial Control System (ICS) ✔✔A device, or set of devices, that m anages, commands, directs, or regulates the behavior of other devices or systems. ICS technology drivers ✔✔Reliability, efficiency, safety, and ease of use. Discrete Process ✔✔A process where a specified quantity of material moves as a unit between works tations and each unit maintains it's unique identity . Batch Process ✔✔A process that requires the mixing of raw materials, usually in a heated vessel. Continuous Process ✔✔A physical system that is represented through variables that are smooth an uninter rupted in time. Hybrid Process ✔✔reactive systems that intermix discrete and continuous processes Process Engineer ✔✔Designs the systems and processes used in the control environment. Field Technician ✔✔Maintains and repairs field devices Programmer ✔✔Implements the individual steps of the process code and deploys the code to the controllers. Operator ✔✔Works in the operations center remotely managing and controlling the process Owner/Operators ✔✔Purchases and uses the system. responsible for safe operation and meeting regulations. Vendors ✔✔Manufacture equipment and software Integrator ✔✔Design, configure, test, train, and refresh systems. Government ✔✔Implement guidance and r egulation programmable logic controller (PLC) ✔✔Computer based, solid -state devices that control industrial equipment and processes. Remote terminal unit (RTU) ✔✔Is installed to report local system information and otherwise communicate with the upstream supervisory system. Connection typically made using RS -232 or RS-485 Intelligent Electronic Device (IED) ✔✔Used in the power industry primarily, and have limited function, but contain their own control logic and are usually micro -controller based. Digita l Protective Relay (DPR) ✔✔Contains a micro -controller with the specific purpose of measuring voltages and currents to determining whether a fault in the system exists. Phasor Measurement Unit (PMU) ✔✔Measure voltages and currents at principle intersectin g locations on a power grid and can output accurately timestamped voltage and current phasors. Communication Gateway ✔✔Facilitates data acquitting, storage, transmission and protocol conversion though the industrial data network. Widely used to apply time stamp data to logs for locally connected RTUs Communication Modules ✔✔Connect FEP into networks of intelligent electronic devices (IED) such as modbus or PROFIBUS. Real Time Operating System (RTOS) ✔✔Runs on an embedded device and is specialized in runni ng programs with specific scheduling paradigm. Microkernels ✔✔Responsible for Inter -process Communication (IPC), virtual memory, and scheduling. Ladder Diagram (Ladder logic) ✔✔Relay logic displays and drawings and was written to be understood by technicians. Operates on rules rather than producers or functions. Each pass over is called a scan, and it occurs many times per second. Function Block Diagram (FBD) ✔✔Uses a series of blocks with a purpose and inputs and outputs strung together. The order by which the blocks executes depends on the Vendor .
