BRX Do-More PLC HTTP Web Server – Website


We will now look at the BRX Do-More PLC Web Server. Ethernet equipped BRX CPUs and the Do-More Designer Simulator can now have a web server. This can be accessed by any web browser using the IP address of the BRX Do-More CPU.
A web server is server software or hardware dedicated to running this software, that can satisfy client requests on an Ethernet network. A web server can contain one or more websites and websites can have several web pages. A web server processes incoming network requests over HTTP and several other related protocols.

The website built into the BRX Do-More has several different tabs that have basic information about the system, status information like warnings and errors, input and outputs, system logs, user logs, and user pages. We will be enabling the webserver on our BRX Do-More PLC and showing the information that is available. This is a great tool for troubleshooting the PLC as you will see. Let’s get started.

P1AM Arduino Modbus TCP to C-More EA9


We will now look at P1AM Arduino Modbus TCP communication to the C-More EA9 Series HMI. This will be communicating Ethernet Modbus TCP protocol. The P1AM will be the server (slave) and the EA9-RHMI the client (master).

We will explain how to connect a headless C-more HMI to our P1AM-ETH Industrial Arduino Ethernet Shield.
The P1AM Example from Automation Direct on GitHub will be used.

We will be using the remote android and windows app to connect to the C-More EA9 HMI. This will display the information from our Arduino P1AM on our headless unit. Let’s get started. Continue Reading!

Click PLC Real Time Clock (RTC) – Ladder Logic


The click plc has a real-time clock that will allow us to control outputs based on a date or time of day. This real-time clock (RTC) can be set from the click programming software or through the program of the controller. Our programs in the click can use the following calendar and clock values:
SD19 – RTC Year – 4 digits (2021)
SD20 – RTC Year – 2 digits (21)
SD21 – RTC Month – (00 to 12)
SD22 – RTC Day – (00 to 31)
SD23 – RTC Day of the Week – 1 Sunday to 7 Saturday
SD24 – RTC Hour – (00 to 23)
SD25 – RTC Minute – (00 to 59)
SD26 – RTC Second – (00 to 59)

We will be using the RTC – Real Time Clock in a sample program. This program will turn on an output Monday to Friday from noon until 1 pm. It will also adjust for daylight savings time. Let’s get started. Keep on Reading!

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. Continue Reading!

BRX Do-More PLC Peerlink Ethernet Network


The BRX Do-More PLC Peerlink Ethernet communication network is one of the easiest networks to set up and run. Peerlink is a shared programmable logic controller (PLC) common memory area within a local network. Do-More central processing units (CPUs) or DirectLogic PLC systems using ECOM100 modules can read the entire area and write to their programmed area if selected.
brx do-more plc peerlink
The network uses TCP/IP broadcast packets to publish the blocks of data PEERLINK (PL) memory to all of the devices attached. This broadcast will share the data network to the local domain only. Each member can optionally send data to the other members of the data-sharing network by electing to “publish” one or more blocks of PEERLINK (PL) memory.
This can sound confusing at first, but it is the simplest network to set up. You can have your Peerlink network up and running in a matter of minutes. We will be setting up and demonstrating the Peerlink network using a BRX BX-DM1E-18ED13 and the Do-More Simulator. Let’s get started. Continue Reading!

Productivity Suite PLC Simulator Software Free Download


The productivity suite software now contains a plc simulator. The software is a free download and is available from automation direct. This software will now allow you to test or troubleshoot your program without the physical hardware present. The entire family of controllers can use the simulator. P1000, P2000, and P3000 emulation can happen on the following parts of the productivity series hardware:
– P1000 CPU’s and local I/O stack, P2000 and P3000 CPU’s and local bases
– All basic I/O modules, both analog and digital
– Modbus TCP Server/Client connections on external Ethernet port
Productivity Suite PLC Simulator Software Free Download
The simulation mode is available on the Productivity Suite version 3.8.x.x or higher. We will be discussing the PAC (Programmable Automation Controller) PLC Simulator. Testing this simulator will be done using our first program (Start-Stop Circuit) and the PID instruction in our Productivity 1000 series. We will also be connecting to physical hardware after using our simulator to test the program. Let’s get started. Keep on Reading!

Omron CP1H PLC to CMore HMI EA9 RHMI


The C-More EA9 Series of human-machine interfaces (HMI) provides a way for the operator to control and will perform a lot of additional items. The free programming software is very user friendly and fully featured. Here are some of the additional items that this robust and powerful HMI can do besides communicating to programmable logic controllers (PLCs).
Send Email – This includes authentication for the email client protocol
Log Data – This can log data files to the internal memory or an external thumb drive (32G)
FTP Server – Use file transfer protocol to retrieve information from the HMI to a network. This can be done automatically with a batch file.
Web Server – This HMI can be a web server on your network
Remote Internet Access – Windows, Android, and IOS operating systems have the ability to take advantage of this remote access to the HMI. The programs are free and fully functional.

Our sample CP1H PLC program will use buttons and indicators to control a start/stop jog circuit. An analog input into the PLC will be scaled and displayed on a gauge and numeric display on our HMI screen. We will also write information to our 7 segment display on the CPU from our HMI screen. Omron serial host link protocol will be used to communicate over an RS485 serial cable. We will demonstrate remote access using our windows and android device. Let’s get started. Continue Reading!

BRX Do-More PLC Modbus ASCII Protocol

Do-more plc modbus ascii protocol will be used to communicate to a  Solo process temperature controller. A sample program will explain in detail how this is accomplished through a serial port.
Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master (Client) and the devices supplying information are Modbus Slaves (Servers). This protocol was originally developed by Modicon systems.
Modbus protocol comes in basically three different types. Ethernet (Modbus TCP) or Serial (Modbus RTU or Modbus ASCII). Modbus TCP and Modbus RTU come as standard protocols in the BRX Do-More series of PLCs.

We will connect the BRX Do-More PLC to a Solo process temperature controller. This will be done using the Modbus ASCII protocol over serial RS485 communication wire. (Media) The present and set values (PV / SV) will be read from the Solo controller and the set value will be written when required. Let’s get started. Continue Reading!
