How to write timing instructions for Mitsubishi PLC Mitsubishi PLC programming software GX Developer tutorial

Question: How to write Mitsubishi PLC timing instructions? With the rapid development of the industrial automation field, Mitsubishi PLC has been widely used in industrial control. In order to achieve more precise control, it is crucial to master the writing of Mitsubishi PLC timing instructions. Solution: This article will introduce you to the writing method of Mitsubishi PLC timing instructions in detail, and guide you to easily master this skill through the use tutorial of GX Developer programming software.

First, we use the X0 input terminal as the timing start signal. When the timing signal is received internally in the PLC, the bit device X1 is turned on. Directly enter [ld x0] at the left bus to enter in the ladder diagram.

We use T0 as the PLC internal timer. At this time, we should pay attention to the type of timer: T0 ~ T199 represents 100ms general timer, T200 ~ T2451 represents 0ms general timer, which can be Input signal backend input [out t0 k30], k30 means 3000ms, which is 3 seconds.

When the timer is over, there needs to be an output signal. This output signal can control external devices and can also be used as a warning light. We use Y0 as the output.

When the timer ends, if the timer is not disconnected or reset, the timer will maintain the last value. We can add a reset command to reset C0. After completion, you can click the test button to simulate.

In the logic test dialog box, you can add a bit component monitoring screen. Click [Software] in the menu and then select [Software Window] to select X and Y. Then you can edit the edited The input and output of the program are manipulated and monitored.

In the X input dialog box, if you click the input button once, the input can be self-locked, and click twice to release the self-lock. When clicking X0, wait for 3 seconds, then Y0 will be output. At this time, if you click X1 twice, you can reset the timer and restart the timer after reset.
