Retentive & Non-Retentive Data Register in Fatek PLC WinProladder Software

Each data register in one data word wide, meaning 16 bits (ones and zeros). The least significant bit (LSB) will be on the right, the most significant bit (MSB) on the left. The word 'significant' refers to the relative binary weighting of the bits. Register data is a 16-bit binary, but we rarely program the data registers one bit at a time. The register address is a storage box, it does not convert or move the data on its own. The CPU instruction set accesses data registers of the PLC using octal addresses.

While using Fatek PLC programming WinProladder software, we have to store data in data register. As we have moved the values of timer (T200) in data register number "D1". For taking a data register in WinProladder, click on [F] function icon from the icon tray and write "R" in the search box in pop up that appears on your screen. Select data register and click on "OK". Then click where you want to place that data register and a new pop up will open as shown below.

You have to write the data register number here. As we have used “D1” in “Move command”, so we will continue that program in this function as well and write “D1”. Let's try this by using a simulator and check will this work or not.

 This is how you can simply use data register to get your required values. I hope this will help.
