None of the two. I used as bellow.

I found the page. But a question. How do I tell the software which is a high speed timer and a low speed timer? I have 100ms set at a low speed timer and 10ms at high speed timer. I use a timer T for a recipe value that goes up to ZR1200 (the recipe registered value). If I put 10 it's one second. But I I put 100 it's not 10 seconds. It's shorter. Why?

Automatic Upload of PLC and HMI software

So it's impossible to create a script that uploads the PLC software automatically to the CPU? -
Automatic Upload of PLC and HMI software
Andrei Blagaila replied to Andrei Blagaila's topic in Mitsubishi
I want to load the SW on a Q50UDEH via Ethernet but using a batch file and not the GX works software. -
Thanks. I think I found the setting.
-
I am running a simulation on a GT15* and every time I touch it it beeps to confirm. Can I disable this from someplace? Thank you
-
You're welcome Glad to know you to.
-
Thank you. I understand now. I think it may have to do something with Recipe logging. You all have been a huge help. Thank you, Andrei

Hey guys. I have some registers in my program that store the values for the recipes. (ex Z13, Z14...). Somewhere though I have the command: MOV D921 Z13Z19 Can some explain Z13Z19?
-
What value do you have set on the HMI to show? The HMI does the conversion automatically I think or I don't know. Bring up a photo of that window in the HMI project file to see it's settings. If you want to have the same number in the PLC in order to compare it you have to load the value as a float in a Word. So maybe add a Word. EMOV D0 Da EMOV D1 Db And then you divide them by 100: EDIV Da E100 Dx EDIV Db E100 Dy And you use Dx and Dy to compare values or to calculate differences or any other things. Dx and Dy are the values identical to the ones on the HMI

D8030 and D8031 are integer numbers. Try using EMOV D8030 D0. This should move them into D0 as floating point. Then you divide it by 100. EDIV D0 E100 Dxxxx. And you will have the same value as HMI stored in Dxxxx. I'm guessing that D8030 is an analogic value that is read by the PLC and you want to compare it with another one. Usually when you read a analog value it arrives without a point in the PLC (ex: 1234 in one of my applications is 123.4 degrees C.) To do operations with it you have to manipulate the value to be shown exactly like on the HMI.

Now I understand. So the value in Z19 is added to the register number and then in that number D911 is moved. It's seems like over complicating things. Why is this used?
-
It actually looks like this.
-
I''m trying to understand why they did it like this. No idea yet :| I'll do some more digging tomorrow
-
Q50UDEH. Can you please explain what it's used for?
-
I used only with Beckhoff 24Vdc LED connected directly to the outputs and did not have any problems.
-
If you want to remove the program try to remove the battery for 10-20 minutes. See if that helps.

I found the manual for the AJ65BT-64RD3. Aftel a while reading I found the example program and understood how the I/O are assigned. I wrote a bit of software but i'll wait for the module and PT100 to test it out. If this solves the current issue of reading the temperature, I will need to find out how to use PWM and PID to control it using ladder diagram
-
Has anyone used a PT100 temperature sensor to control the temperature in a certain environment? I want to use it over CC-Link. Any suggestions for modules and for temperature control any ideas how to do them? I have never worked with PT100 on Mitsubishi and i'm clueless how it's done.

Q CPU with CCL but i'm not sure about the version. My Master CCL is a QJ61BT11N. I found the manual for the remote RTD reading module. The first step is to understand how to get the data that the PT100 reads and then how to manipulate it to have a value. All my program (many POUs ) is written in ladder. I don't think I can use one of the POU that's reserved to write a FB program or can I? I'm fairly new to Mitsubishi and don't have a lot of knowledge of what is possible and what not. After I do this I need to figure out how to control the temperature. From my understanding they want to use solid state relays (semiconductor relays). I'm guessing PWM is the way to go in that case? I will look over the manuals today and try to see how can I read from the module but if you can give me some examples how to get the info from the module and manipulate it, they would be extremely appreciated.
-
I would apreaciate a generic example. Let's assume I have a sw made in ladder. I'm not able to use function block. I want to control a temperature in a room using a PT100. 35 degrees for example. How can I do that?
-
Do you guys have any examples of PID control in ladder? Or documentation?
-
RTD signal? Sorry I'm new to analog signals. I know about 4-20 and 0-10 but i have never heard of RTD. I need to use over CC-Link because i need to measure the temp on the field near some remote I/O's where I plan to insert the new PT100 module. Do you have some examples of how to do a PID in ladder (SW is done in ladder) and how to read the analog signal?

Distance Measure with rotary encoder 2phase A/B
Andrei Blagaila replied to BUJAR GASHI's topic in Mitsubishi
C251 is turned on. To use it always you can you: M8000 ---------------------------------------C251 D2 This abilitates the counter always when the PLC is running. The counter goes up to the Value D1 which is not set so you don't to worry about it. --------------------------------------DMOV C251 D0 From M8000 you take another branch that moves the value of C251 in D0 and D1. I hope this answers your question -
I have looked over the manual. try writing like this at the beggining: M8000-------------------------TOP K0 K0 H3300 K1 ( The analog input channels (CH1, CH2) are setup by writing H3300 to the BFM #0 of the FX2N-4AD.) -------------------------TO K0 K1 K4 K2 (sets the number of average samples to 4 for CH1 and CH2) --------------------------FROM K0 K5 D0 K4 (Here i'm not sure if K4 is correct. I would try with K2 first). Try this and tell me if it works
