PLC Learning Series – Programming Steps


Developing a programmable logic controller (PLC) program can be broken down into five different steps. These programming steps are as follows:
Five Steps to PLC Program Development
Step 1 – Define the task
Step 2 – Define the Inputs and Outputs
Step 3 – Develop a logical sequence of operation
Step 4 – Develop the PLC program
Step 5 – Test the program
These five steps to PLC program development will help you in understanding, programming, and troubleshooting your automated machine.
PLC Learning Series – Programming Steps
We will be looking at each of these steps in a little more detail as we discuss the PLC programming development. Let’s get started. Keep on Reading!

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!

PLC Training Series – Tutorial for Everyone


Invented in 1968 by Dick Morley, the programmable logic controller (PLC) is a simple rugged industrial computer. This free plc training series is designed for everyone to learn about these controllers. PLCs are constantly evolving and continue to be the best option for a variety of industrial automation applications.
PLC Training Series - Tutorial for Everyone
Even though the PLC is changing, core items remain the same. We will be discussing this in more depth for each of the components mentioned in the picture above. Let’s get started learning about PLCs. Keep on Reading!

BRX Do-More PLC Ethernet Remote IO BX-DMIO

We will now look at the BRX do-more plc ethernet remote IO. The BRX Do-More PLC has its own line of remote input and output expansion units. You can add up to 8 I/O expansion units per controller (CPU) and 8 BRX expansion modules per expansion unit. This will make your system grow with your needs.

The remote I/O expansion units feature the following:
• All units have built-in Ethernet port, 10/100 Mbps
• MBIO units have onboard RS-485 port with removable 3-Pin connector
• Support for 8 expansion modules
• AC and DC powered units available
• AC powered units include an integral 24VDC auxiliary output power supply
• Power connector and serial port connector included
BRX Do-More PLC Ethernet remote IO
We will be looking at the BX-DMIO-M. This is the Do-More Ethernet Remote I/O supported protocol unit. We will discuss the hardware and then connect and configure the unit to work with our existing BRX Do-more PLC. Let’s get started. Continue Reading!
