Practical Tips and Techniques
Do-More Designer software features a fully functional simulator that can be used for teaching PLC programming. This software is free of charge.
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
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
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
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
