Hello I am at a loss here. There is something happening with TON_2 that also affects the variable STEG. Even though the input to TON_2 is false, IN and Q are true. Suddenly IN and Q turn false, and at the same time variable STEG makes a jump from 3 to 4, even though criteria for this step is not confirmed. Have had to override this fault by introducing a SR-latch and outside of block make a comparison between NIVÅ_FÖRRÅDS_KÄRL and 150.0 By the way, TON_2 is not declared globally. Would be very happy for suggestions and pointers. Cheers // DAN PE2 Jump.avi PE1 Jump.avi

HI Everyone,  Recently i have bought a plc fx3ge and gt2000 hmi .the problem is that whenever i use a device address d280.b1 in hmi .i am not able to use the same address in gx works for plc (LD D280.1).can anyone help me with this problem.   

Does anybody use it successfully? With what kind of RSLinx activation? I am using The Studio v28.00, which installed the v2.00 of the Tool and v 3.80.00 of the RSLinx. The latter is activated as Classic Single Node. I can see the processor in RSWho. The Tool fails to start, with the shown message. What may be wrong? Please, do not suggest links to the Rockwell articles that require the support contract, as we do not have such.

I am using GX Works2 and I cannot use the format "Label.1" to access the first bit in the word represented by label. Is this a function that just does not work or is it abnormal. Is there a way to do this easily. I am using structured ladder. Also is there a way to use the K*, notation with an array of bools represented by a label. I saw elsewhere the syntax K8<Label>, but that will not compile for me.   

Im having some trouble with a PLC and looking for a some help. Whats happening is output number 3 is stuck on. I thought maybe it was just the PLC. I pulled the program tried it on a new PLC with no luck. I checked for faults and the handheld shows no major faults. The output that is stuck on is for a door, its telling it that the door is open. Any help would be great.

hello. out there. I need som help. I never user Beckhoff Twincat before. but now I have a smal project on Twincat. after two days to undersatnd the Twincat . I still don't understand how to make configure hardware on twincat. som body can help me please or telle me where I can find the doc. thanks

Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool

Hello, I'm new to this forum and PLC world in general (especially to Mistubishi PLCs). I have a task in which I need to synchronize servomotor with another motor that runs conveyer (servomotor needs to stamp a label on a foil on a conveyer), in GX Works3. Servo motor is run by Simple Motion module. I need general tips on how to make pulses from encoder into something useful that can be used to send data to Simple Motion module. I need high speed counter to count pulses (never actually did this, I got this from manuals), how would I, for example, get speed out of it? Number n pulses, divide it with time it took to get to n pulses? How would I make Simple Motion to make servomotor on his Axis #1 to rotate at same speed?    

Hello everyone. I can't find my ST program step count in GX WORKS 2. Does anybody knows where is program step count in GX WORKS2 ?

I used to use the Old Dos based MEDOC very many, many, years. I havn,t programmed for years now. We have GX Works 2 at work, and I am practicing programming an FX 3G - 40M to try and keep my hand in. Allthough I can write and read the program ok, the PLC keeps saying that it has no memory for the comments. Apparently the memory has to be set on the PLC. Any advice or information links will be appreciated

 

I need help with a program I wrote for school that didn't work quite right.  I have to make a chasing light program that will freeze the lights when a PB is engaged and reverse when PB is engaged on light 1.  The assignment has already been turned in but our instructor ( if you want to call him that) has told us a similar sequence will be on the final.  Can anyone help me out??

Dear Experts!!! Actually i have two problems : 1.    I want to change the object (FT View SE v8.0) property to "VBA controlled". But its not allowing me to do it,  like as you can see on the pic.   2.    I want to make an array of objects in FT View like as shown in the pic (Image of VB form): the object name is azul and the index is 0 so the object shown in the pic is azul(0) VB Form code is : Private Sub Form_Load() Dim i As Integer For i = 1 To 224 Load gris(i) azul(i).Visible = True Next i azul(0).Visible = True For i = 0 To 224 azul(i).Top = gris(0).Top azul(i).Width = gris(0).Width Next i For i = 0 To 224 azul(i).Left = azul(0).Left + i * azul(0).Width Next i End Sub As you can clearly see in VB code I have created one object only, but rest of the objects are being created by Code only I want to do the same thing in FT View SE v8.0 Please please help!!!!!

I have a problem when trying to download a program from a FX1S-30MT PLC. I am using a SC-09 USB cable. The software i am using is GX Developer 8. When trying to download the MAIN program the screen in the attachment appears. I tested the download from another PLC of same model and have no problems, therefore the cable is ok, and the laptop is ok. When downloading of the parameters and comments does not give error, just when trying to download MAIN. Also I tested connection with Test Connection button and says communication is ok. Anyone who can help? I have a doubt, how can i see the communication parameters on the PLC side? Thanks a lot

Hello All! Long time engineer first time programmer. Any help is greatly appreciated. I have an automated Beer bottle rinser, filler, and capper that I need help diagnosing a problem. We purchased the machine in July and it ran great until a couple weeks ago when it doesn't seen to be reacting to bottles being present anymore. FX1s-30MR Here are the symptoms: When a bottle is run around the filling carousel, there is a prox sensor to detect it's presence (X007). There is also a sensor under the machine on the gears to detect timing (X006) When a bottle is detecting there is a slight delay, then the pneumatic valve for the purge fires (Y001), followed by the valve to fill the bottle with beer (Y002). Even though, the LED light on both the sensor and the I/O illuminate confirming that it is receiving the the input signal from that sensor, no output signals are being sent. My first instinct was to check all electrical connections and swap out the prox sensor just to be safe, but still no dice.... So I purchased a USB-RS422 FX cable and downloaded the demo of GX Works 2 to better try to pin point the issue. Using the monitor function on GX works 2 I can again confirm that the PLC is receiving the correct signal from X007 when a bottle is present, however the outputs Y001 and Y002 have a constant value of 0... Unfortunately this program is not simple enough for me to really understand, so maybe someone can make more sense of it than me. (see attached). Also, Not sure if its related, but when I ran the check program there is a double coil error revolving around the Beer inlet solenoid. This is to let beer into the filler bowl, not the bottle. oh and the manufacturer won't be able to help for a couple weeks when they can send a technician... Any thoughts, comments, or questions are appreciated. Cheers, Eric screenshot2.bmp screenshot1.bmp

How do I assign an IP address to an S71200 CPU for the first time? Is it possible to do it over ethernet? Thanks in advance!

Software: GX Works3 I'm really struggling to understand GX Works online / offline operation. (I know they've been consistent in how this works for the past ten years - but it's consistently bad!) I can't find how to work in offline mode. I powered off the PLC and the software keeps trying to connect. I've cleared the PLC memory and am trying to download the complete program to an FX5U. (I was able to do it earlier. I'm still able to communicate with PLC over Ethernet.) I'm getting:Unable to write target file because it is the following status. (sic) - Unconverted - Converted function block does not exist in FB file. - Converted function block does not exist in FUN file. - Unconverted module label. There are no red items in the navigation tree. There are no errors after a Rebuild All command. What do I need to do to figure out what the problem is? Many thanks.
