3 Basic Components for PLC/RTU Automation
3 Power Supply - Typically 24Vdc or 12Vdc- The source availability on ac-dc converter (rectifier) pr battery - Low distribution - Typically 230Vac - The source availability on main supply or generator - High distribution
3 Central Processing Unit (CPU) Programming Setup/Setting Communication
3 Input & Output Digital / Discrete Input or Output Signal For value only ‘1’ & ‘0’ Typical 1=On/Start/Open 0=Off/Stop/Close I/O Physical Communication Retrieved from others or 3rdpart devices. Require standard protocol for data transfer Example: modbus, profibus, HART Analog Input or Output Signal Numerous value Examples: 0,1,0.3,-2.5,1000... In form of current or voltage signal. Example: 4-20ma or 1-5V.
3 Input & Output – Measuring 4-20mA (12-4) (20-4) X 100% = 50%

3 Programming & Configuration Typically IEC1131-3 standard; Function Block, Ladder Diagram, Structure Text Basic, C language. Tags Logic structure Timer Function (Mathematical, Incremental) PID (proportional–integral–derivative)
3 Communication Protocol Definition: Communication protocol is a system of rules that allows two or more entities of acommunications system to transmit information via any kind of variation of physical quantitiesNotes: Without a protocol, two devices can only be connected but not communicated. Just as a personspeaking Japanese cannot be understood by a person who only speaks Spanish
3 Communication Protocol Example of communication protocols: DNP3.0 ModBus IEC-60870-5 IEC1131 IEC101 HTTP – Hyper Text Transfer Protocol (Web based) SNMP – Simple Network Management Protocol (IP Based)

4 Communication - VPN What is Virtual Private Network (VPN)?VPN stands for “Virtual Private Network" — a servicethat helps you stay private online. A VPN establishes a secure, encrypted connectionbetween your computer and the internet, providinga private tunnel for your data and communicationswhile you use public networks. Benefits: Change location Protect privacy Increase security
