BRX Do-More PLC FTP Client Get Put


We will look at the BRX Do-More FTP (File Transfer Protocol) on our PLC. Using FTPGET and FTPPUT instructions we can transfer files to an FTP server. Our BRX Do-More PLC now has the ability to be an FTP Client. This will allow us to transfer our logged files to an FTP server that we programmed in the following post.

As an FTP Client, the Do-More PLC now has the ability to transfer and retrieve files from the network at an appropriate time in the PLC logic.
BRX Do-More PLC FTP Client Get Put Windows 10 FTP Server
We will be setting up a Windows 10 FTP server on our computer. Using the FTPPUT FTP Client command on our BRX Do-More PLC we will store a file on our FTP server. The FTPGET Client command instruction will be used to retrieve a recipe text file on our server. This recipe file will have three timers that we will be used in a sample program to turn on some outputs. Let’s get started. Continue Reading!

BRX Do-More PLC Dynamic Web Pages


We will now look at creating BRX Do-More dynamic web pages on our PLC web server. These pages are great for operator information display. A dynamic web page is a web page that displays different content each time it’s viewed. For example, the page may change with the time of day, the user that accesses the web-page, or the type of user interaction. There are two types of dynamic web pages.
Client-Side Scripting – Web pages that change in response to an action within that web page, such as a mouse, keyboard action, or timer, use client-side scripting. Scripting languages such as JavaScript will allow this updated content to your users.
Server Side Scripting – Web pages that change when a web page is loaded or visited use server-side scripting. Login pages, forums, and shopping carts are examples of server-side scripting. PHP, ASP, Perl, and ASP.Net, are some of the languages that can be used.
BRX Do-More PLC Dynamic Web Pages
Previously we enabling the HTTP web server, set the whitelist, and reviewed the website on our BRX Do-More PLC. We will be using JavaScript in our HTML web page to create dynamic content for our BRX Do-More PLC. These pages will be stored on the SD memory card and transferred to the RAM memory upon powering up our BRX Do-More PLC. 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!

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!

BRX Do-More PLC to Modbus TCP RTU Remote IO BX-MBIO

The BRX Do-More PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

We will connect the BRX Do-More PLC to the Modbus remote IO. This will be done using the Modbus TCP and Modbus RTU protocol. Ethernet and serial RS485 communication to the BX-MBIO unit will be the media.
The BX-MBIO remote I/O expansion units feature the following:
• RJ45 Ethernet port for communications via Modbus TCP
• RS485 serial port for communications via Modbus RTU
• Supports up to 8 additional Expansion Modules (Add the discrete or analog I/O you require)
• AC and DC powered units available
• AC powered units include an integral 24VDC auxiliary output power supply
• Power connector and serial port connector included
