Practical Tips and Techniques
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
The C-More EA9 Series of human-machine interfaces (HMI) provides a way for the operator to control and will perform a lot of additional items. The free programming software is very user friendly and fully featured. Here are some of the additional items that this robust and powerful HMI can do besides communicating to programmable logic … Read more
We will now look at the arduino thermocouple module. The productivity open P1AM industrial arduino P1000 thermocouple module can be connected to our P1AM-START1 ProductivityOpen starter kit with Ethernet. We will be programming our arduino thermocouple module using the configuration tool on Github and productivity blocks. The productivity open P1AM I/O interface chip-set supports the … Read more
Arduino consists of a family of single programmable circuit boards and the IDE (Integrated Development Environment) that uses a streamlined version of C++ to write and upload code to the boards. Many pre-configured circuit boards, called “shields”, are available to expand the functionality of the Arduino controller. These shields can provide Ethernet, WiFi, GPS, LCD … Read more
A watchdog is a piece of code that will timeout when an error occurs in our program. It will usually cause the CPU (program/sketch) to stop or reset. We will now look at the instructions for the watchdog timer in productivity blocks. This includes the Configure Watchdog, Start Watchdog, Stop Watchdog, and Pet Watchdog. Our … Read more
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 … Read more
