    I feel both great joy and sadness watching these videos and it’s conflicting. Great joy in that I learn sooo much than in my own job in Operations, Process & Automation Controls. Great sadness and it saddens me to admit it here also in that I don’t learn this much in my own job in Automations dealing with all these components, devices, protocols and plc’s and that saddens me greatly. I started my career as a Operational & Mechanical Technician in Operations at Utility and Power Plants. I now more work in Field Service, Equipment Commissioning, Plant Startups and Automations. The engineers when they even try to explain stuff are never close to this clear in explaining anything at a simple level either. As my own company also don’t believe in training or sending anyone to training. Sadness to me. But great joy watching and learning to fill in the gaps in my knowledge watching these videos. Every video I see I can relate to something done in my job or where I wasn’t clear in how something worked. The easy explanations here fills in my knowledge greatly and with great joy. I can’t say just how much I enjoy watching the videos here and know it’s directly affecting my job and what I know as well when I look at the devices, components, plcs etc.

    Cool video! You have 5 modules:
    1) A power supply
    2) CPU315-2 DP Power Supply 1P 6ES7 315-2AG10-0AB0
    3) 6ES7331-7TF01-0AB0 | HART Analog Input Module
    4) What is this module and it's function?
    5) What is this module and it's function?
    On module 2) Does RS 232 connect to the PC with a USB and a HART modem?

    • @realpars
      @realpars  3 роки тому +1

      The fourth and fifth modules are analog input modules just like module 3. They were added just to show that a CPU315-2 rack can have multiple I/O modules. The programming terminal is connected to the CPU using either a Profibus-DP connection or an MPI connection. These are both serial links that require a special modem or PCI card at the computer end. A HART modem is used to communicate with a HART device in order to configure the sensor. This connection is external to the PLC hardware setup.

    I wish to have a clarification, how to connect non-hart field transmitter having output 4-20 mA with HART communication network or HART enables PLC? Whether i can go with adapter to make my field device into HART enabled?

    • @realpars

      A HART-enabled transmitter still requires a 2-wire connection at the Analog I/O card. PLC cards typically allow selection of HART mode and non-HART mode (i.e., HART enabled or disabled) for HART-enabled analog cards. If you have a transmitter capable of HART communication, you can choose to use the HART functionality or not, but enabling or disabling HART communication at the I/O card. Leaving the I/O channel with HART disabled allows traditional 4-20ma loop-powered signals to be sensed at the analog input card. You should refer to the manufacturer's I/O card documentation for verification of this feature. An analog or digital transmitter cannot be converted to a HART transmitter with an adapter. A transmitter must be manufactured as a HART device.

    So since the Hart signal is a frequency wave, is it AC voltage riding on the DC 4-20mA?

    • @scottlampe70
      @scottlampe70 4 роки тому

      Not quite. If you recall, a rectified dc voltage is not quite flat, it has its peaks and troughs like ac voltage, but they average out to a dc voltage above zero. Rewatch at around 12 minutes.

    Great video, i would like to know which PLC are you using... and if you can use the HART protocole with any Siemens PLC (more specifically with the S7-1200 and S7-300).

    • @realpars
      @realpars  5 років тому

      The video did not specify the PLC model since it is showing how HART is used in a universal, generic way. For use with an S7-1200 or S7-1500, you just need to make sure that your analog input card is one that supports HART protocol. There are HART-enabled AI cards (and AO cards) available for most all of the Siemens S7 PLC models.

    Is there any way to have sensors send interrupts to masters? or can sensors only respond once told by the master?

    • @realpars
      @realpars  3 роки тому

      HART protocol is based on the older Bell 202 protocol. In this node-based protocol, only Master nodes can send data requests. Sensors (nodes) do not have the facilities to generate interrupts or initiate communication.

    • @realpars
      @realpars  Рік тому

      Hi there,
      Thank you for your question, and our apologies for the delay in our response.
      To ensure a reliable engineering setup, here are a few key steps I would recommend:
      1. Select the Right Cable: Begin by choosing the recommended cable for your specific application. It should invariably be a shielded cable.
      2. Conduit for Long Runs: If you have an extended cable run, it's advisable to encase the cable within a conduit. This practice is typically endorsed by the HART device manufacturer.
      3. EMF Signal Isolation: For optimal performance and minimal electromagnetic interference (EMF), adhere to the distance recommendations outlined in the data sheet. Maintaining adequate separation from EMF sources is crucial.
      Following these steps is standard procedure for the installation of HART or any 4-20mA signals, and it helps to minimize the risk of EMF interference.
      Happy learning!

    One question with the Profibus communication network, can you send analog data? If it is not possible then the profibus cannot regulate the process, therefore it only sends information from the sensor to the plc but does not regulate the process, is this correct?

    • @realpars
      @realpars  Рік тому

      Hi there,
      Thank you for your question, great one! Profibus communication converts all the signals in the communication protocol needed and transmits them, then converts them back to the receiving end. The PLC regulates the process as needed.

    Thanks, very informative. Question: Can an Ultrasonic flow sensor with HART output been connected to an analogue input card that does not support hart, if only the 4-20 mA signal is used?

    • @scottsommer6480
      @scottsommer6480 5 років тому +1

      Yes, but the HART capability will not be available to the control system. However, the HART signal is still being communicated, so using a handheld or PC-based interface can still make use of the HART signal. Many plants use this approach. The advantage of using a HART-enabled PLC or DCS analog input card is that you will have the secondary PV, SV, and TV all available to the control system, as well as the primary PV and diagnostic info about the device.

    Is it possible to read the process values digitally, i.e. skipping the A/D in the PLC I/O module, using HART? (Meaning the 4-20 mA is not used for anything really)

    • @realpars
      @realpars  3 роки тому +1

      Yes. When HART is enabled, it is used to collect the PV data. The 4-20ma loop current is used to power the device, even though the analog signal is not used to develop the PV value.
