Building a PLC Program that you can be Proud of

Building a PLC program series will take you through developing and programming PLC logic. This six-part series was released almost seven years ago but is still relevant today. Each part will add and build upon the previous step. This series will look at different ways to solve the same machine logic.
Using discrete inputs and outputs to control traffic lights and cylinders, we progress we introduce additional methods to solve logic. We look at sequencers in a new way and learn how to write programs to allow users to teach the new sequence. This will develop your PLC programming skills. The Do-More Designer programming and AdvancedHMI (VB.Net) software are utilized without purchasing physical hardware. Let’s get started.

PLC Learning Series – HMI – Interfacing

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.

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.

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.

Omron CP1H to C-More Micro HMI Communication

The C-More Micro HMI panel is a series of human-machine interfaces (HMI) that provide a way for the operator to control and view your programmable logic controller. (PLC) The free C-more microprogramming software is user friendly and fully featured. C-more Micro panels can easily display text, graphics, and bitmaps to effectively communicate critical data to your operator.

We will connect the EA3-T4CL cmore micro HMI screen to the Omron CP1H PLC. The devices will communicate serially via an RS485 interface. We will demonstrate reading and writing bits and words from the HMI unit. Let’s get started.

C-More Micro HMI Object Recipe Component

The C-More Micro HMI Panel software uses virtual components called Objects. Recipe buttons are part of these objects. The Recipe Button Object changes the value of a tag or multiple tags. The Recipe Button Object looks and acts like a Pushbutton Object on the screen. When the Recipe Button Object is pressed, the values in the Source Data Tags are written to Destination Data Tags.
C-More Micro HMI Object Recipe Component
We will now look at recipes that we can use with our HMI micro panel. They include the recipe button. We will program 3 recipes into the unit that will control 4 different timers. Let’s get started.
