Program Operation Monitor , Start Bit and Change Register.

“Program Operation Monitor”, “Start Bit and Change Register”.

The remaining parts to create and modify today’s textbook programs Which started from the 10th episode.
Program Operation Monitor:

In GX developers it is possible to check what is happening inside the program and check the program’s bit conditions. This process of viewing is called Program Monitoring. How to see ………………

1) Click on the ‘Online’ pull down menu.
2) Go to ‘Monitor’.
3) Select ‘Monitor Mode’.

A small pop up box will be displayed, there will be PLC Mood (Run or Stop) and show the program’s average sken time. Now the X10 and Y0 will not be highlighted, but X11 is highlighted. Here it is understood whether the input device is connected or whether the output device has got energy. In a highlighted contact and inclined it can be understood that it is connected. See X10 and Y0, their inputs and outputs respectively, but they are not true (true). See X11 on the other side, whose input is off-off, but this is true.

On the X10 by Toggle Switches When toggle switch will be on, the program will highlight the bit. But on X11, the highlight will come from Normal. In this situation, the level of the ladder will not be true. That is, the level of a ladder is true when the step is completely highlighted. If both X10 and X11 are highlighted, then the step is true. Note here that the output on the ladders stage is true. That means the Y0 will be highlighted. The output will be activated when Y0 is highlighted.

Enter the Ledar Monitor

This feature allows the programmer to monitor multiple steps in a non-sequential manner.

1) Copy and paste the ladder step 3 times. To create four different steps, contact the contact and change the address of the caller.
2) Keep the program in monitor mode.
3) Go to Online → Monitor → Entry Data Ladder.
4) Go to Window → Tile Horizontally.
5) Highlight the 4th level of the lidder in the window below.
6. Hold down the highlighting step, then drag it to the top screen and click the release.
7) Step 5 and step 6 for the 1st and 3rd grade steps.
8) Minimize it by activating it by clicking on the top screen.
9) Keep the window in monitor mode.
10) Toggle switches and see results.

Turn on bits and register

By doing this, you can run a section often by changing the PLC code while writing the program. This program allows you to easily modify a small part of the program by checking it out. It can be done without switching and using other devices. The same thing is said to be boring (forcing). See how to do it below.

1) Keep the PLC in the running mode.
2) Open the program and keep the GX developer in the monitor mode.
3) Simply press the Shift key and double click on X10.
4) Do the job again to change the number 3.

Note that, on Y0, when X10 is off. In reality, the FX series PLC can actually have a correct input, only a scan force. In reality, outputs that are used in Ladder logjes can be properly forcibly for a single sken. Whenever any address is given in physical input, it replaces it with the actual input condition, this is the time when the physical input is to be read at the beginning of the PLC scan. The output used by the PLC code, based on the next PLC scan, returns to the program’s controlled output state. Internal bits, such as M relay, which can be kept on forcing, until they are not controlled by the PLC program.

This is an easy way to turn on and off contacts and relays. It should never be done when PLC is connected to a running system in any way. It should be kept in mind that a warning message can change at the moment of change and which can lead to dangerous consequences. See below

1) Go to Online → Monitor → Entry Data Monitor → Device Test.
2) Enter X10 in the Device Device box, in the Bit Device section.
3) Click on Force ON.

It is possible that correctly insert numbers into the data register through this dialog box.

1) Enter the D0 in the Device TaskBox in the Device Devices section.
2) Enter 10 of the standard set Teskbox.
3) Click the Set command button.

Check whether the Data Register D0 is set to 10.

1) Go to → Online → Monitor → Device Batch Monitor.
2) Enter D0 in the Device Taskbay.
3) Click Start Monitor button.
