  1. Programabilni logički kontroleri PLC – moduli za proširenja Industrijski sistemi i protokoli - predavanje 5

  2. Sadržaj 1.Proste PLC periferije – ponavljanje 2. Slozeniji PLC periferije, razni HMI (primer text display) 3.Moderne IT tehnologije, modem, Profibus, Ethernet , Internet

  3. Moderni načini proširenja PLC Standardni načini unosa i iznosa informacija • Unos - Tasteri , prekidači, analogni signali • Izlaz - sijalice, releji, kontaktori Moderni načini proširenja • Preko serijske veze, PPI i MPI ili preko Profibus mreže (ne može S200) • Preko kabla za proširenje

  4. Primeri inteligentnih HMI koji se preko serijskog kabla povezuju sa PLC – OPERATORSKI PANELI

  5. HMI – Operatorski paneli • Dva osnovna dela i funkcije panela: 1. ispis - display - samo tekstualni - grafički - monohromatski - u boji 2. unos - tasteri i tastatura - sa predefinisanim značenjem (minimalno konfigurisanje: up, down, OK, ESC) - slobodni za konfigurisanje - numerički - tastature

  6. 1. Tekst displej TD200 - operator panel Primer povezivanja PLC preko serijskog kabla sa inteligentnim HMI (proizvođač Siemens)

  7. 1. Tekst displej TD200 - operator panel • Suitable for simple HMI applications in connection S7-200 • LCD displeywith • two rows for 20 characters • Four function keys (buttons) F1 to F4 • Foursystem keys (buttons) - (up, down for listing through messages and parameters setting, OK – confirmation, ESC –return) • Connection to the PLC SIMATIC S7-200 or to the PC with only one interface PPI (peer to peer interface)- RS 485. • Speed: 9,6/19.2/187,5 kbit/s. • Vizard za konfigurisanje u MicroWin 4.1. Ne treba WinCC-Scada ili neki složeniji program kao SIMATIC Manager za S300

  8. 2. Touch panel TP070 Touch panel TP070 (Siemens)

  9. 2. Touch panel TP070 • Suitable for simple or more complicated HMI applications in connection with PLC SIMATIC S7-200 • It is possible to display user grafics, dynamic bar graphs, dynamic application variables, user buttons in four intensities of gray graphics resolution 320x240 pixels • One interface RS 485, maximal speed 19,2 kbit/s • life cycle 6 years continuously • For programming: TP Designer in collaboration with MicroWIN V3.1 and higher.

  11. Moduli za proširenje S200

  12. Moduli za proširenja

  13. 1. EM 241 Modem module • The EM 241 provides an international telephone line interfaceand supports sending numeric and text paging messages, aswell as SMS (Short Message Service) messages to cellularphones. This is useful for remote diagnostics and maintenance,machine control, alarm systems, and general communicationfunctions. • In addition to CPU-to-CPU communication via a telephone line,the EM 241 also supports Modbus RTU protocol, a protocolthat has been widely used for many years.

  14. 2. CP 243 - Ind. Ethernet module • CP 243-1 and CP243-1 IT communication processors are used to connect anS7-200 PLC to an Industrial Ethernet network.

  15. 2. CP 243 - Ind. Ethernet module • Both modules, CP 243-1 and CP 243-1 IT,can beused to connect an S7-200 PLC via Industrial Ethernet to acomputer running STEP 7 Micro/WIN. • This allows the S7-200PLC to be configured, programmed, and diagnosed remotely. • In addition, an S7-200 PLC connected to an Industrial Ethernetnetwork can communicate with S7-200, S7-300, and S7-400PLCs and a variety of other devices. CP 243-1 IT je jači, on može i na internet • The IT functions of the CP 243-1 IT Internet module simplify theprocess of setting up a control system that can email diagnosticinformation or transfer files using Internet protocols.

  16. 3. EM 277 - PROFIBUS-DP module • EM 277 PROFIBUS-DP module allows connection of theS7‑200 CPU (CPU 222 and above) to a PROFIBUS-DP networkas a slave.PROFIBUS-DP is an open, international fieldbus standard that allows a broad range of intelligent devices fromvarious manufacturers to communicate rapidly and efficiently.

  17. 4. EM 253 Position Module • Position control describes a range of applications that involvemovement with varying degrees of precision. The EM 253Position module is a simple but powerful positioning modulethat enables the user to control position systems from microsteppersto intelligent servo drives (with integrated closed-loopcontrol). Features of the module include: • Provides high-speed control with a range from 20 to200,000 pulse per second • Supports both S curve or linear acceleration anddeceleration • Provides a configurable measuring system that allowsyou to enter data as engineering units (such as inches orcentimeters) or as a number of pulses • Provides configurable backlash compensation • Supports absolute, relative, and manual methods ofposition control • Provides continuous operation • Provides up to 25 motion profiles with up to 4 speedchanges per profile • Provides four different reference-point seek modes witha choice of the starting seek direction and final approachdirection for each sequence • Provides removable field wiring connectors for easyinstallation and removal

  18. 5. EM 231 Thermocouple and RTD module • The EM 231 thermocouple module • Thermocouple is a junction between two different metals that produces a voltage related to a temperature difference • - EM 231 is for temperature acquisition using standardthermocouples with a high precision. • - 4 inputs +/- 80 mV, 15-bit resolution+ sign, • thermocouples type J,K, S, T, R, E, N • Type K (chromel -alumel) • alumel(95% nickel, 2% manganese, 2% aluminium 1% silicon ) • chromel (90 percent nickel and 10 percent chromium) • EM 231 RTD module • 2 inputs for thermistors • Više tipova RTD senzora • Platinum resistance thermometers • Pt100/200/500/1000/10000 • (Pt100 = 100 ohm na 0C) • Nickel resistance thermometers • - Ni100/120/1000, Cu10; • resistance 150/300/600 Ohms, • 15-bit resolution + sign • Supports 31 standard rs. temp. sensors
