PLC Learning Series – Memory Backup


PLC memory is very similar to personal computer memory. There is the operating system and firmware of the processor and connected modules. PLC programs and data that are used by the program are also stored in the memory.
PLC Learning Series – Memory Backup
We will now look at the basic understanding of memory in the PLC. Looking at two examples of PLC specifications. We will see how the program is stored and how long data memory will remain when the PLC is not powered up. Let’s get started. Keep on Reading!

Solo SL-SOFT Installation – Temperature Controller Software


All Solo Standard Process Temperature Controllers that support RS-485 serial communications can use the SL-SOFT configuration and monitoring software. This free package will communicate to monitor multiple SOLO controllers using Modbus RTU or Modbus ASCII protocols.

Solo SL-SOFT Installation - Temperature Controller Configuration and Monitoring Software
We will be installing the SL-SOFT configuration and monitoring software package on our Windows 10 PC. Communicating through our Waveshare USB to RS485 adapter, Modbus RTU will be used as the protocol to establish communication. 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!

C-More Micro Program Quick Start


We will now look at the C-More Micro program quick start. This will demonstrate how to quickly get your C-More Micro Program up and communicating to your programmable logic controller. (PLC)
C-More Micro Program Quick Start
The general steps involved with a human-machine interface (HMI) program will include, program development, ladder logic, and HMI program development. We will be breaking the HMI program development into program purpose, tag import, HMI programming, simulation, and testing.
An EA3-T4CL C-More Micro HMI will be used to communicate to a Click PLC via Ethernet. A Start/Stop circuit will be programmed with a Timer. This can be controlled via the PLC inputs or HMI inputs. The timer present value (PV) will be shown on the HMI. The set value (SV) of the timer can be changed using the HMI. Let’s get started. Continue Reading!

C-More Drop-Down Menu Create – All Models


The C-More can create a drop-down menu. This applies to all models of the HMI controller. A drop-down is a menu that offers a list of options. The currently selected item in the list is always displayed. When the visible item is selected (touched), other items from the list “drop-down” into view, and the operator can choose from those options.
C-More Drop-Down Menu Create
We will be creating a drop-down menu using a C-More Micro HMI. (Human Machine Interface) This could also be done using the EA7 or EA9 C-More HMI controllers. The EA3-T4CL will be communicating to a Click PLUS PLC. A ladder logic program in the PLC will control the operation of this operator interface drop-down menu. Selecting a question on the drop-down will give an answer on the corresponding Lookup Text display. Let’s get started. Continue Reading!
