  1. Basic Programming Simatic S7-300 By: Andri Kuncoro

  2. SIMATIC Overview

  3. SIMATIC Controller (PLC) S7-400 S7-200 S7-300

  4. S7 – 300 • Features : • Modular small controll system • Performance graded range of CPU • Extensive selection of modules • Expandable design with up to 32 modules • Backplane bus integrated in the modules • Can be networked with MPI, Profibus or Industrial ethernet • Central PG/PC connection with access to all modules • No slot restrictions • Configuration and parameter setting with the help “HW Config”

  5. S7 – 300 Mode Selector MRES = Memory reset function STOP = Stop mode, program not executed RUN = Program execution RUNP = Program execution, read/write access Status Indicator SF = Group error, internal CPU or fault in module BATF = Battery fault DC5V = Internal 5 VDC voltage indicator FRCE = FORCE RUN = Flashes when the CPU is starting up, then steady light in Run mode STOP = Show steady light in Stop mode SF DP = Physical bus fault BUSF = No configuration or incorrect configuration

  30. Digital Operation BIT BYTE For a unit of 8 binary characters, the term BYTE is used. A byte has the size of 8 bits. WORD A word also has the size of 2 bytes or 16 bits. DOUBLE-WORD A double-word corresponds to the word length of 32 binary characters. A double-word also has the size of 2 words, 4 bytes, or 32 bits.

  31. Digital Operation Beberapa operand di S7 : • Operand input(I) Bit I 0.0 - … Byte IB 0 - … Word IW 0 - … Double Word ID 0 - … 2. Operand Output(Q) Bit Q 0.0 - … Byte QB 0 - … Word QW 0 - … Double Word QD 0 - … 3. Operand Flag(M) Bit M 0.0 - … Byte MB 0 - … Word MW 0 - … Double Word MD 0 - … 4. Operand Timer(T) T 0 5. Operand Counter(C) C 0 6. Operand Peripheral(PI) Input Byte PIB 0 - … Input Word PIW 0 - … Output Byte PQB 0 - … Output Word PQW 0 - … 7.Operand Data(D) Bit DBX 0.0 - … Byte DBB 0 - … Word DBW 0 - … Double Word DBD 0 - …

  32. Digital Operation PULSE TIMER
