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 … Read more
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 … Read more
The Do-more PLC Modbus ASCII protocol will be used to communicate with 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 … Read more
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 … Read more
We will be looking at the Modbus remote IO BX-MBIO-M controller. This is the Do-More Modbus 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. The BX-MBIO Modules are remote I/O controller modules that provide a … Read more
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 … Read more
We will now look at the BRX Do-More PLC Modbus TCP remote io using Stride Field io. The BRX Do-More PLC can use remote inputs and outputs from Stride. The Stride Field I/O Modules are simple and compact. They provide an economical means to connect inputs and outputs to an Ethernet Modbus TCP communication network. … Read more
MQTT stands for Message Queuing Telemetry Transport. This simple publish and subscribe communication protocol does not take too many resources. Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine to machine (M2M) connectivity which is ideal for the Internet of Things. (IoT) This protocol is not for remote IO or real-time … Read more

Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine to machine (M2M) connectivity which is ideal for the Internet of Things (IoT) or Industrial Internet of Things. (IIoT) … Read more
The purpose of a ramp soak profile is to make gradual, controlled changes in temperature (Ramp), followed by a temperature hold (Soak) period. We will be using our Do-More Proportional-Integral-Derivative PID Instruction with PWM output that we looked at last time to apply the ramp/soak profile. This will be done on the BRX Do-More PLC. … Read more
