A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software.
HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, electricians, engineers, and programmers all have different needs. The machine HMI(s) must provide or make the information easy for all the people who use the system.
We will now look at some of the ways that human-machine interfaces (HMI) are used in automated systems today. Let’s get started. Keep on Reading!
The Productivity 2000 series of programmable logic controllers has a slim DIN rail density form factor. This means that this micro-modular PLC can have a power supply, CPU, and seven IO modules in only 10-1/2 inches. Input and output cards can be installed, removed, or replaced without turning the power off to the PLC system. (Hot-swappable) This means that your system can remain running while troubleshooting your system hardware. The Productivity 2000 hardware supports up to 240 local I/O for discrete, analog, and motion applications with a high-performance CPU equipped with five communications ports and 29 discrete and analog I/O modules. Several remote IO options are available on this award-winning PLC in the Productivity series family.
Productivity 1000 (Stackable Micro PLC)
Productivity 2000 (Micro Modular Programmable Controller)
Productivity 3000 (Modular Programmable Controller)
These three series by FACTS engineering currently make up the Productivity Series PLC from Automation Direct.
We will be looking at the features of the powerful P2000 controller. Let’s start by looking at the P2000 hardware. Keep on Reading!
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. A simple conveyor is one of these machines. This is usually the starting point for learning about the machine simulator. This conveyor example will use two digital inputs and two digital outputs. A pallet will move back and forth on the conveyor. When the pallet is detected on each end it will stop and reverse direction. If both motors are started at the same time, the motors will burn up. This will be demonstrated. The machine simulator will allow you as the programmer to make mistakes before trying your program in the physical world.
The Click PLC will be used to program this virtual machine. Using the Click Plus PLC, we will connect the simulator to the simple conveyor 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!

In this Covid-19 world, we are continuing to adapt. Social distancing, mask-wearing, hygiene, etc are the way we currently live. Video conferencing with Zoom, Teams, and Google Meet are the norm in business today. Information is knowledge, and everyone more than ever wants to be able to see, control and summarize production data on a regular basis. Open intuitive technologies are available to communicate like never before. Industrial plant data is rapidly changing. Factory 4.0 benefits are being seen and everyone wants to take advantage. We are looking forward to the New Year and new possibilities for implementing your control solution.
Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you. Keep on Reading!
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. The gantry loader is one of these machines. It will pick up metal boxes from a conveyor and place two on a wooden pallet. The Click PLC will be used to program this virtual machine.
Using the Click Plus PLC, we will connect the simulator to the gantry loader 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. The logical sequence step will include a flow chart and a sequence of operations. The sequence of operations will be done using indirect addressing in the Click PLC. Let’s get started. Keep on Reading!
