The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with either the RS232 or RS485 ports on this PLC. Modbus RTU is an open (published) protocol that uses the Master / Slave architecture. It’s a … Read more
The productivity series of PLCs has a built-in web server. This web server function can make a non-secure (HTTP) connection to the CPU. This is done with your browser. You can then view read-only system tags and open, save or delete files stored on the micro SD drive. Previously we stored data logged files on … Read more
The productivity series of PLCs has a built in data logger. This easy data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of … Read more
The productivity series of PLCs has a Drum and Sequencer instruction. Drum instructions are great tools. They mimic an electromagnetically drum sequencer. Have you ever seen the mechanisms of a music box? Ok so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is … Read more
Shift registers will move (shift) bits in a word (register) to the left or right. If we look at an example of boxes moving along a conveyor belt, the boxes would represent the bits in the register. The movement of the conveyor would be the shifting of the register that represents the movement of the … Read more
