Hello: I need to link a lot of variables, pointing to CIO address, like "AT" field, but is a large volume of tags to create, so, I have a chance to assign a memory location to a variable in ST like: my_tag := %100; (trying to assign tag address to CIO 100) ? If not, there is a method to import tags from a Excel ? Thanks.

Enable Analog Channel in RSLogix 500 // First Scan Bit, COP function?
James275 posted a topic in Allen Bradley / Rockwell Automation
Hello all. I have been working with an SLC 5/04 system, which houses various Digital and Analog INs and OUTs, up to Slot 29. I am currently mainly working with Slot 25, an Analog Input: 1746-NI16I. This is a system which has already been set up and has been running for the best part of 8-10 years. This particular card has had some spare inputs, one of which I am trying to connect to. In the Advanced Configuration, only a few Channels are actually "Enabled", and each channel is pretty much slightly different from another in terms of Input Type, Filter Frequency and Data Format. I am trying to set up Input 14, which is Channel 15, to "Enable" it, 4-20mA Input Type, Filter Frequency of 6 Hz and Data Format of either Raw/Proportional or Engineering Units. Now, after I have made my choices, I click apply, and then OK. I am then confronted by a pop-up which states: "Configuration Rung and Data Integer Data File Number: 25 Integer Data Element: 100 Rung to be inserted: XIC S2:1/15 COP #N25:100 #O0:25.0 24 At Program File Number: 4 82" I have the options of OK or Cancel. If I click OK, I now have LAD 4, Rung 82 Highlighted. This First Scan Bit and COP function were already here, but does that mean I have now altered what is being written to "#O:25.0"? I now Download the Changes. However, after all this, I am not getting any Analog input reading coming in from the Live PLC. What is this COP function? What does it do? How do I properly set up this Analog Card? Thanks for your time, -Jame -
Was wondering if anyone can tell me whether it is possible to use the Red Lion Graphite displays to remotely log into your system via Ethernet for programming. Can it be used as a bridge to other Ethernet devices connected to it?

So I did this simple Function Block, pretty simple, and yet it keeps giving me this error, after a bunch of failed combinations the error persists, without telling me whats wrong. And therefore won't even allow me to download the program to the PLC (CJ2M CPU31) or even simulate. I heard it's a simple thing to fix but I really dont know how to, since I'm quite new to this. Here's the function block itself in the picture and the programming inside it, although since it gives me no errors, i don't think that would be the problem

Is there a Block Compare Instruction like the one in Omron PLC for Mitsubishi PLC? If the Omron PLC is BCMP (68), then what is the name of the instruction on the Mitsubishi PLC? I tried to use BKCMP in the Mitsubishi PLC, but the way it works is not the same as the one in Omron PLC

Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.

Greetings, so i create project for FX3U in GX Works2. In my program i use function in ST. That function return array with word(signed). I have a warning: ST FOR i_var := 0 TO n_i BY 1 DO TempNumbs := Numbs; TempDevSetsOnPerTime := DevSetsOnPerTime; QueueBySetOn[i_var] := 0; END_FOR; QueueBySetOn[1] := TempNumbs[n_i]; QueueBySetOn[3] := 1; FOR i_var := 0 TO n_i BY 1 DO IF (TempDevSetsOnPerTime[TempNumbs[i_var]] < MaxSetsOnPerTime) THEN QueueBySetOn[0] := TempNumbs[i_var]; QueueBySetOn[3] := 0; EXIT; END_IF; END_FOR; So, it realy funny, GXW cant return int?

Hello, I am trying to define a struct as an input variable for a Function or Function Block. For example the function AddDelimiter (This is a standard Sysmac function), has a input variable with the variable type Struct, an it is possible to couple a struct to this input (See picture below). If i try to make my own function block with a struct or Structure as an input data type, i get the following error (See picture below). When I try to define a struct from the data types (In this case struct: Test) it doesn't give a error. But when I try to couple a struct to this input, that is a layer deeper than the function block struct i get the following error (See picture below). How can i define a struct as an function/ function block input? Thanks in advance.

Hi friends , recently i ve been doing some diggings about remote IO cards, in my factory we have a CJ2m PLC and it communicates with remote IO cards with four numbered words (2080.00 , 2080.01, 2080.02....2080.15 ) and there were several dip switches on the IO cards, which were set but i can't understand what was the basis of that settings. So I'd like to know how these dip switches behave and what are the uses of them ?? and how is it possible to have 4 numbered word bits ?? pls help me someone to clarify this, i tried internet, but cudnt help myself !!! thank you Here I attach one of the pictures i took of one of the remote input cards.

Anyone ever used a Wait-for digital tag in a C Program? I have to use C in the Red Lion Programs.. but, I'm not at all proficient in C (or anything else for that matter ..) Here’s a nice problem for basic C programming .. I really need to solve it .. but, so far ... can't ... sigh!: I have an actuator that will be commanded to make sine wave motion. The program that does that, in the actuator’s driver-controller, requires the actuator to first be in a zero position. Homing has already been done, so the drive knows where the actuator is. I cannot modify the sine wave program; but, can command a Move Absolute program in the drive, to take the actuator to zero, if it isn’t already there. When the actuator is at zero, it is “In position” and a digital tag will go True. If the Tag is False, the actuator is not at zero, it’s at some other position, and only the Move Absolute program can return the actuator to zero. So, when launching this position command program, In a Red Lion G3 HMI, using only Basic C programming, how would you write a control program that would test the status of the actuator’s position, and, finding it at zero (the “InPos” tag is true) would start the Sine Wave program. And, If the “InPos” Tag is false, would start the Move Absolute program, which would return the actuator to zero, and when the actuator is In Position, would start the Sine Wave program. Here’s the tricky part. It will take only a few milliseconds to start the Move Absolute program (if required) .. but how do you get the “C” control program you are writing, to wait until the actuator actually reaches zero, and the “inPos” tag goes true … which could take several seconds? I don’t believe there is a WaitFor function in “C” , and you cannot send either the Move Absolute, or the Sine Wave program more than once .. so, if a loop is used, it can loop only one time .. presumably with conditional delays. (however that's done) You cannot use Sleep().. that would be cheating.. the full program must run in the least amount of time, and you do not know how far the actuator is from zero. You could use if (! InPos) or if (InPos) to qualify what programs to run .. but, where does the “Wait for In position” fit into C Programming? You might be able to use Continue .. but, ya still have to wait for “InPos” to go True…..before running the Sine Wave. Thanks Much, Regards, Michael

I am fairly new on this forum & PLC's, usually i read and get tips from here.I use a RsLogix 5000 PLC software. I am currently working on a project at home that requires me to read from a Access DB. What type of Instruction or method do i go about, initially reading from Access? I know Excel is possible It's an existing system. Add on functionality/feature. I am using a barcode scanner that will link up to a Access DB to verify the barcode is legit and send this info to a different system via PLC/EthernetThe access DB is used because its a older system, it uses that. So it is possible? and guessing from what your stating, its is more involved to get the system working eventually?PLC = A&B 1769-L23-QB1 CompactLogix Controller I am using FactoryTalk View Studio as HMI, do not have SCADA.I have a control logix chassis. Thank you in advance...

changing time of schedule block
wouter94 posted a topic in Modicon / Telemecanique / Schneider Electric
Hi, I'm working in so machine basic v1.5 and I'm wondering if it is possible to change the start time and stop time in a schedule block with a %MW. So is there a possibility to for example say %CH0.??? := %MW5 in an operation block? And is there a page where u can see al the possible codes. I already discovered that %TM0.P changes its preset but i don't find a list of al those possibility's. -
Hello All, I am using Wonderware InTouch 10.0 on Windows 7. It's slightly outdated, but its what we have. I am currently writing a script using the StartApp command to open a particular PDF file with the touch of a button. My script looks like StartApp("C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32 C:\1.pdf"); The first part of the command runs adobe and the second part of the command opens the particular file "1". What I need to figure out is, how do I insert a variable into a string. For example I have 55 files I may potentially need to open up, all named 1-55. So I need the file I am calling to be a variable inside of the string so I can call it inside of a loop. I do not want to copy and paste this code 55 times, I want to make the file name a variable (tagname that is a memory real between 1 and 55) so I can run it in a loop. I have only been using Wonderware for a month or so now, so If anything is confusing feel free to ask. Thanks!

Hi All, I'm still quite new to Unity and Modicon PLCs. I have a PLC program running in simulation mode for development/test and I'd like to follow the logic inside a running block. I can't seem to just double click the function block while online to see it's 'inside' logic. Is there a way to inspect the inside of a running function block? How can I check and diagnose the logic a running function block? Thanks!

Good morning folks, I've browsed this forum often enough over the past few years that I think it's time I finally signed up. Lots of good ideas and advice that I've benefited from and I hope to return the favour some day. So on to my question.... I'm currently knee deep in a project using a CJ2M PLC and I have to send and receive chunks of data over Ethernet/IP. To do this, I'm using the ESATR and EGATR commands (set / get attribute). I would like to know if these commands finish execution (ie. the ethernet port completes the transaction) even if the input conditions to the command are no longer true. Specifically, if I use the "port ready" system flag (A202.00 is an input to my FB in this case) as a condition to trigger the ESATR command, this bit will go low once the port becomes busy (ie. during execution). So will that interrupt the completion of the ESATR command resulting in an incomplete transaction and data loss? I've looked through the help files on the command but don't get a clear picture of how it behaves. Perhaps the attached JPEG shows more clearly what I mean. Thanks, PC

Hello, Im looking for the in built function blocks, but i cannot find it in the program files/ omron folder where the manual says (even with search for *.cxf), perhaps i dont have it installed, but where can i get them from? As i remember i downloaded cx-one from the official omron web page after login etc, so thats why i dont understand why am i missing the fb libraries What else place there is to find useful FB-s? Thanks!
