BRX (Do-More) PLC PID Ramp Soak Profile

We will be looking at the BRX Do-More PID Ramp Soak Profile instruction in the PLC. 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 Proportional-Integral-Derivative PID Instruction with PWM output that we looked at last time to apply the ramp/soak profile. Using the immersion heater in a cup of water to keep the temperature at a constant value, we will be adjusting the profile of the temperature as we increase the setpoint (Ramp) and hold that setpoint for a predetermined time. (Soak) We will then decrease that temperature back to the original setting. (Ramp) We will be modifying our existing program from our PID with the PWM Output post. Let’s get started.

Here are just a few. - Standalone PLC with built-in I/O - Built-in Data Logging - Communication ability - Ethernet Port, RS232, RS485, USB - support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet) - Built-in Analog input and output - Integrated motion control - High-speed counters - Powerful instruction set (Video of Instructions in software) - Ability to expand the system with a variety of modules - Part of the Do-More series of PLCs which use the same free software. (Do-More Designer) - Integrated simulator in the software capable of external communications for testing The BRX series of programmable logic controllers consist of four different units. They differ depending on the Inputs and Outputs built into the unit and if it has the ethernet port. No I/O Micro PLC unit – (BX ME) 10 Point Micro PLC unit – (BX 10/10E) 18 Point Micro PLC unit - (BX 18/18E) 36 Point Micro PLC unit - (BX 36/36E) These CPUs (Central Processing Units) are also known as MPU (Multi-Processing Units) because of communication capabilities. https://www.accautomation.ca
