How to Read the PLC Datasheet?

A PLC's datasheet contains a wealth of information that covers nearly every feature the PLC is capable of offering. The technical specifications of the PLC, such as the supply voltage, input and output types, and power rating of these IO points, will be your main concern if you are the installation engineer. The historical data may not be as important to you if you are only a PLC programmer. Instead, you will concentrate on information about the PLC memory, the amount of IO available, and the ability to add new modules.

The following details in the PLC data sheet must be examined, depending on the different manufacturers:

- PLC Memory 
- Current and Voltage Rating 
- Addressing Various Blocks and Data Areas
- Specifications for Inputs and Outputs
- Interfaces and Protocols for Communication
- The Ambient Situation

Different PLCs will have different features and capabilities, hence different information will be displayed on different PLC data sheets. Depending on whether you are an installation engineer or a PLC programmer, as we previously said, you may not find all of the information in the datasheet to be significant.

Example of PLC ladder diagram for Filing and Heating Liquid in Tank

In the previous post, I wrote PLC program about Mixing and Heating process. Today, I'm going to write about Filling and Heating process in tank. It sounds like the same topic in previous post. Actually, it is different. We'll see the sequences and processes.  Here is the given sequences according to the Author : 1. Fill the tank up to 80%. When the tank is filled, turn ON the heater to raise the temperature up to 70 deg. 2. When this temperature is reached, turn OFF the heater & open the outlet valve. 3. When the level in the tank falls below 10%, close the output valve. In this situation, I do the ladder diagram via Sysmac Studio which is the product of Omron. I just remind you again, most of the control processes are used with Mitsubishi, Siemen and sometimes Delta's PLC due to cost effectively. I'm going to show you how it works with Sysmac Studio. In this case, I'm only using Name Tags. Before I'm talking about ladder diagram, I would like to tell about ...

IPv4 Vs IPv6 - What's the difference between IP Addresses

ကျွန်တော်တို့ IOT Project သို့မဟုတ် PLC တို့ HMIတို့ကို Ethernet နဲ့ချိတ်တဲ့အခါမှာ IP Address တို့ Subnet Mask တို့သတ်မှတ်ရတာတို့ကိုတွေ့ရမှာပါ။အခုကတော့ IP Addressအကြောင်းကိုမှ IPv4 နဲ့ IPv6 အကြောင်းကိုရေးမှာပါ။           IP Address ဆိုတာကတော့ ကျွန်တော်တို့ရဲ့အိမ်နံပါတ်လိုသဘောမျိုးလုပ်ထားပေးတဲ့ Internet Protocol တစ်ခုပါပဲ။ အိမ်တိုင်းအိမ်တိုင်းမှာသူရဲ့သက်ဆိုင်တဲ့နေရာလိပ်စာတွေရှိကြသလိုပဲ စက်တိုင်းမှာလည်းသူရဲ့ သက်ဆိုင်တဲ့ IP Address တွေရှိကြပါတယ်။ ဒါကတော့ IP Address အကြောင်းကိုရှင်းပြတဲ့ရိုးရှင်းတဲ့ ဥပမာတစ်ခုပါ။ ဒီမှာအဓိကထားပြီးရှင်းပြသွားမှာကတော့ IPv4 နဲ့ IPv6 ကိုရှင်းပြသွားမှာပါ။      What is IPv4 : simple meaning & features guide     ဒီ IPv4 မှာဘာတွေပါလဲဆိုတော့ Set Numbers လေးခုပါဝင်ပါတယ်။ ယေဘုယျအားဖြင့် ဘယ်လိုပုံစံနဲ့ရေးကြသလဲဆိုရင် 106.102.77.43 (ဒါကဥပမာပုံစံပါ။) လိုပုံစံမျိုးဖြစ်ပြီးတော့ မတူညီတဲ့ ကိန်းဂဏန်းလေးခုကို Cover လုပ်ပေးထားပါတယ်။ IPv4 ဘာကြောင့်ဖြစ်လာရလည်းဆိုရင် လွန်ခဲ့တဲ့ 1980 ဝန်းကျင်ကာလတွေမှာ I...

What is Master Control Relay in PLC?

A PLC's Master Control Relay (MCR) is defined by experts as a unique relay utilized in ladder logic programming to regulate the operation of several rungs or parts of a ladder diagram. In essence, it uses certain conditions to determine whether to enable or disable particular software sections. All rungs between the MCR and the associated end instruction are executed when the MCR is turned on. These rungs cannot run if the MCR is deactivated because they are circumvented. Large portions of a program can be controlled with a single condition because to this functionality, which enhances program organization and efficiency. In first photo, Master Control Relay is used as normally opened coil, called Master Coil. As you can see when the "Start" is triggered, Master Coil will be closed contact and executes the multiple rungs. If "Stop" is triggered, Master Coil is disable the execution of the other rungs. Similarly, in second figure, I...
