Click PLC EasyPLC Warehouse Stacker Example


The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The warehouse stacker example is one of these machines. Pallets are loaded and unloaded into the stacker machine. A maximum of 30 pallets can be stored. The stacker will work as a FIFO (First In First Out) device. This means that the pallets are stored in a sequence and retrieved in a sequence.
Click PLC EasyPLC Warehouse Stacker Operation
The Click PLC will be used to program this virtual 3D stacker machine. Indirect addressing (pointers) will be used to track the positions on the stacker to store and retrieve the pallets. Using the Click Plus PLC, we will connect to the warehouse stacking machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this FIFO is programmed. Let’s get started. Keep on Reading!

Click PLC – EasyPLC PLC Mixer Programming


The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The industrial mixer is one of these machines. When the start pushbutton is energized it will fill up a tank until the lower level sensor is detected. The mixer blades will then be turned on until the top sensor is detected. The tank is then drained past the low sensor and the process repeats for 3 cycle times. Once the sequence is complete, the tank is completely drained and ready to start again.

The Click PLC will be used to program this virtual 3D mixer machine. A DRUM instruction will be used in the PLC for the sequencing. Using the Click Plus PLC, we will connect to the mixing machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. Let’s get started. Keep on Reading!

Click PLC Retentive Data Memory Registers


The Click PLC retentive data memory registers are not included in the program file by default. All Click PLC CPUs are included. This option must be selected to include the C, CT, DS, DD, DH, DF, CTD, and TXT memory in the Click project file.
Click PLC Retentive Data Memory Registers
We will be enabling the option to include the retentive data memory in the Click program file from the Click programming software. We will also be installing a battery and programming an expiry date. This will indicate when the battery will need to be replaced. Let’s get started. Keep on Reading!

Click PLC – Easy Transfer Line Programming


EasyPLC Software Suite is a complete PLC, HMI, and Machine Simulator Software package. This PLC learning package includes a Machine Simulator (MS). This virtual 3D world with real-time graphics and physical properties can communicate to several different programmable logic controllers. (PLC)
Click PLC – Easy Transfer Line Programming
We will be developing a Click PLC program for a transfer line. This is just one of the prebuilt machines in the simulator to learn PLC programming. We will be developing the ladder logic, connecting via Modbus RTU, and testing our program. This will be done using the five steps to PLC program development. Let’s get started! Keep on Reading!

Click PLC Serial Communication Timing


Many questions come from serial communications using the Click PLC. Most of these questions deal with communication timing when using multiple send and receive instructions. We will show you how to deal with serial communication timing in the Click PLC.
Receive and Send instructions will allow you to send and receive serial data to an external device. The communication method that you set up can be ASCII or Modbus. ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer. Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices.
Click PLC Serial Communication Timing
We will demonstrate the Send and Receive instruction by communicating Modbus RTU to a Solo Temperature Controller. Parameters from the Solo process temperature controller will be read using multiple receive instructions. The send instruction will be used multiple times as well to set the Set Value (SV) and Limits of the SV value entered in the temperature controller. The set values will only be changed when required. Let’s get started. Keep on Reading!

Click Plus Real Time Clock Setup and Use


The real-time clock on the Click Plus can now be more accurate. A network time service (NTP or SNTP) has been added to the Click Plus controller. This will allow the time to be synchronized with an internet time server or local network. Daylight savings time is quickly implemented with just a memory retentive bit that we can turn on and off based on the time change in the area.
Click Plus Real Time Clock Setup and Use
We will be setting up the network time service on our Click Plus. The real-time clock (RTC) will be updated via the internet time service. Daylight savings time and the RTC will also be programmed. This will be based on our previous Click Real-Time Clock post. Let’s get started. Keep on Reading!
