Connecting to the CPU

To program the SIMATIC S7-1200 from the PC you need a TCP/IP connection set the computers IP address

Windows (Start - Settings - System control - Network connections - Local Area Connection Properties - Internet Protocol (TCP/IP)) (IP address: 192.168.0.99 Subnet mask: 255.255.255.0)

set the SIMATIC S7-1200 IP address TIA Portal (Online & Diagnosis - Project view - Online

accesses - Network Connection - Update accessible devices - MAC= .. - Online & diagnostics) (under Functions - Assign IP address - IP address: 192.168.0.1 - Subnet mask: 255.255.255.0 - Assign IP address)

Reset CPU to factory settings

What is a PLC and what are PLCs Used For?

PLC - Programmable Logic Controller

device that controls a process

printing press for printing newspapers, a filling plant for filling cement in bags, a press for forming plastic shapes, etc....

instructions of a program that is located in the memory of the device

How does the PLC Control the Process?

through the PLC connections called outputs (actuators)

control voltage of 24V

switching motors on and off, opening and closing valves, turning lamps on and off

How does the PLC Get the Information about the Process States?

from the so-called signal transmitters that are wired to the inputs of the PLC

sensors that recognize whether a work piece is in a certain position, or they can be simple switches and pushbuttons that may be open or closed

Break Contact Elements and Make Contact Elements

break contacts

make contacts

Address Individual Input/Output Signals

6

How is the Program Processed in the PLC?

process image of the inputs (PII) process image of the outputs (PIQ)

Logic Operations in the PLC Program

Logic operations are used to specify conditions for switching an output.

Programming languages

Ladder Diagram (LAD)

Function Block Diagram (FBD)

AND Operation

AND Operation

AND logic in the FBD

OR Operation

OR Operation

OR operation in the FBD

Negation

How is the PLC Program generated?

PLC program is generated on a PC using the software STEP 7

PC is connected with the TCP/IP interface of the PLC

program can be transferred with a load function to the PLCs memory

PC is no longer needed for further program processing in the PLC

How is the PLC Program generated?

KONFIGURCIA A INNOS PLC

Module Spectrum

SIMATIC S7-1200 is a modular automation system

Central modules CPU with different capacity, integrated inputs/outputs and PROFINET interface

Module Spectrum

Power supply PM

Signal boards SB for adding analog or digital inputs/outputs (CPU 1211, 1212, 1214)

Module Spectrum

Signal modules SM for digital and analog inputs and outputs

Communication modules CM for serial communication RS 232/RS 485

Module Spectrum

Compact Switch Module CSM with 4x RJ45 socket connectors 10/100 Mbps

SIMATIC memory cards 2MB or 24MB for storing program data

Operating Modes of the CPU

Operating Modes STOP - CPU does not execute the program, and

you can load a project

STARTUP - CPU performs a startup

RUN - program is executed cyclically, projects cannot be loaded in the CPUs RUN mode

CPU does not have a physical switch for changing the operating mode

Operating Modes of the CPU

The operating mode (STOP or RUN) is changed on the operator panel of the software STEP7

button MRES to perform a general memory reset and displays the status LEDs of the CPU.

Operating Modes of the CPU

LEDs for ERROR to indicate errors and MAINT to indicate that maintenance

VYTVORENIE PRVHO PROJEKTU RIADENIE LISU

Riadenie lisu - zadanie

Riadenie lisu - zadanie

Lis je vybaven bezpenostnou klietkou Tlaidlo TART S3 aktivuje lis ak je uzavret klietkou Poloha klietky je sledovan senzorom uzatvorenia

bezpenostnej klietky B1 Lis je riaden cez 5/2-cestn hydraulick ventil M0 (privdza

tlakov mdium na lisovaciu matricu, ktor vylisuje vrobok)

Lis sa automaticky zdvihne ak je splnen niektor z podmienok: je stlaen Havarijne STOP tlaidlo EMERGENCI OFF snma klietky je rozpojen B1 lis sa dostal to krajnej polohy vysunutia, o signalizuje senzor
