Practical Tips and Techniques
Modbus RTU will be the serial (RS485) method in which we will communicate between the AdvancedHMI Screen and the Automation Direct Solo Process Temperature Controller. We can address up to 247 (Solo 1 to 247) devices on this master-slave protocol. A maximum of 32 devices (Nodes) on the network can communicate to the master. A … Read more
We will be installing a USB to rs485 installation on our computer. The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 … Read more
People often ask “What is a PLC?” and “PLC Meaning”. A programmable logic controller (PLC) is a piece of hardware that isolates inputs from outputs. Programs are written to look at the inputs solve logic and set the outputs to perform work. Today we are going to look at the basic fundamental way we program. … Read more
We will continue the series by looking at a sequencer controlling seven cylinders that can be taught. The cylinders can be operator programmed from the AdvancedHMI screen. You will be able to select what cylinders to activate at each step and program in 500 steps. Our PLC will be the Do-More from Automation Direct. Here … Read more
We will now look at the Game of Simon for our part 5 in this series of building a PLC program. Learning all about bit manipulation and sequencers Simon is a memory game introduced in 1978. It has four colored buttons, each producing a particular tone when it is pressed or activated by the device. … Read more
We will now create a PLC with HMI Training and learning environment. We will use the Automation Direct Do-More programming software tied into the Advanced HMI learning package via Modbus TCP. All of the software is free and fully functional. Learn PLC programming and use a powerful HMI (Human Machine Interface) easily and freely. Setting … Read more
