I have a screen display HMI model : OP325 Thank you so much for your time and consideration. Letralong this is normal it is warning you that you have read variables and the values may have changed. I don't know setting values in registers D228, follow Attached picture below.Ĭan you showed me the ways setting values in registers D228 = 100 ? How is setting values in registers D ?Ĭan you make an example attach or can you make setting values in registers D how ? I don't know setting memory or setting values in registers D howĬan you showed me step by steps setting values in registers D ?
If you did get a program to run, it could be dangerous because the PLC probably is hooked up to Outputs that may run motors, turn on heaters, and do other things that you would not expect. Any strange PLC program that you get will not be set up for the same model, or the same Inputs, or the same outputs, so it probably will not run in your particular Mitsubishi PLC. There are many different Mitsubishi models, and each model can have different Input and Output modules. You may not be able to get the old program restored exactly as it was. If there is important operating data in the PLC, that will be lost.
The PLC could have a password set, keeping you from doing anything to it (let us hope it has in this case). Because it is a scanned program from top to bottom, only the last case of an Output will work correctly, nullifying all previous cases. The 2nd use will cause an error in your program. Note that you should not use each Output coil -( )- more than 1 time. These 2 errors are present for all 3 Output rungs. Right now with your logic, the 1st and 2nd branches keep all Outputs ON all the time. For example, on Rung 1 top branch, you need this:įor the same error on the 2nd parallel branch, you need to inhibit the branch when all 3 inputs are on (so that the 3rd branch can cause the flashing action. What you need on the top branch of each Output rung are 2 bits to keep the single input from acting UNLESS the other 2 bits are OFF. You can see in the attached picture that with all 3 Inputs ON, your timer will not flash the bits, because they are already held ON by the top branch of each rung.
But here is your logic inserted into the LogixPro Simulator (as best I can interpret it).
With your experience this type of thing is probably automatic, but coming from other software into Mitsu it’s not very obvious.You have some of your Input numbers mixed up. I've known these things and many others for a while now but I still stumble across little things like that all of the time so I know I'm probably still doing things the hard way. Same with the toggle bit shift/enter when I had been using the debug dialog. For example, I had been drawing and erasing rungs using f9 or the toolbar icon for quite a while before I realized you could do the shift/arrow thing. For example, in the youtube video offered in 4warders comment above (thanks!) he gives a few tips that I had to figure out the hard way. I've used the software occasionally for a while and keep stumbling across ways to do it quicker when I had been doing things the hard way. It's not so much that I am having problems that I can't figure out a way around.
