Modbus RTU TCP Remote IO Controller BX-MBIO

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

BRX Do-More PLC to Stride Field IO Modbus TCP

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

BRX Do-More Simulator MQTT Publish Subscribe

MQTT stands for Message Queuing Telemetry Transport. It is a simple publish and subscribe communication protocol that 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) or Industrial Internet of Things. (IIoT) … Read more

BRX (Do-More) PLC PID Ramp Soak Profile

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

BRX (Do-More) PLC PID with PWM Output

A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a … Read more

BRX PLC INC DEC 512 Registers for DMX512

We will now look at inc and dec 512 registers using the BRX Do-More PLC. This is to control DMX512 fixtures. I was recently asked the following question after posting the Analog Dust to Dawn program: ” I was wondering if there’s an easy way to increment and decrement a range of values. e.g. I … Read more
