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.

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.

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

Hi, I encountered a specific problem during work with GXWorks2 & GTDesigner3. In my part of group project I need to receive from proper script, array of values of sine wave. I need to get 1500 values of sine wave and fill registers in GXWorks and have no idea why my script does not run. I'm using simple while loop with no errors statement from Syntax Check. My script should calculate sine values from index 0 to 1500, and substitute it to registers D2000 - D3499. Look in attachments for better understanding my trouble. I'm looking forward to hearing from you as soon as possible. Greetings, Jan P.S. I'm new in Mitsubishi Equipment programming so if it's some kind of beginner's problem - please be merciful for me.

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. -
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!

Hello. A colleague sent me a screenshot (attached) with a peculiar issue. An ADD function that only sends 0 as the outcome, and a DTOS function that only sends " . I have confirmed that all variables used in the ADD block are declared as integers, and both SumInt6 and String10 are not currently being modified somewhere else. This impatient colleague is baffled, while I am just sharing this issue in the hopes that someone will eventually come with the simple answer that we are overlooking, or a complex one that we could never hope to realize by ourselves. Thanks in advance.

Hi! Anyone can help regarding this issue. I'm not able to monitor the Motor Block that I have created. there's no error either in the output screen but i'm thinking what is the cause of not running in the simulation which shows the Motor Folder RED even it was compiled. thanks for the help! Note: I'm new in mitsubishi.

Hi, i want to make a function block which will contain a block GP.CPRTCL (for predefined comm protocol). GP.CPRTCL has an input "Un" who only receives constant (H,K). On input of my own function block i can set a constant variable, but inside block that variable isn't a constant anymore (GP.CPRTCL doesn't recognize a variable). Is there a way for receiving constant variable in GP.CPRTCL block ("Un") if it is in another block. Regards

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

in Citect i use the following function to associate various Tags with the next popup window, in the previous versions the tags passed to the trend fine since upgrading to 7.4 the trend pens dont display but all the values display fine. FUNCTION // function AssPIDPopup // Expand a full set of PID tags and open // the PID block supergenie AssPIDPopUp(STRING sSGenie,STRING sBasePIDTag) AssVarTags(-2,0,sBasePIDTag + "_PV"); AssVarTags(-2,1,sBasePIDTag + "_SP"); AssVarTags(-2,2,sBasePIDTag + "_OP"); AssVarTags(-2,3,sBasePIDTag + "_MAN"); // Now the tags for the PID tuning SG AssVarTags(-2,4,sBasePIDTag + "_KP"); AssVarTags(-2,5,sBasePIDTag + "_KI"); AssVarTags(-2,6,sBasePIDTag + "_KD"); AssPopUp(sSGenie); END I added a button to run the following code FUNCTION Loadtrend() TrnSetPen(19, 1, AssInfoEx(1,0)); TrnSetPen(19, 2, AssInfoEx(2,0)); TrnSetPen(19, 3, AssInfoEx(3,0)); Prompt("Test"); END when clicked the pens set to the trend fine, i tried to run the code from a function but it did not work. i am new to citect and am sure i am missing something stupid.

There are a lot of instructions in function block that are missing the enable input that is present when programming in ladder logic, such as ADD or MOV. It seems to be very limiting. The only way around it that I know of is to write your own function block in ladder logic or statement list and use that. I seems rather limiting of a language if it relies on other languages for it to be usable. Does anyone know why the enable bit was left out in many function blocks when it is so useful in ladder logic? Pat

I'm having trouble with some very basic programming using function blocks. Specifically Connect Components FB programming, but I think it is a general, common application. Using ladder logic, it is easy to set a value based on the status of a bit. If the bit is false, move a zero into the variable. If the bit is true, move and 88.0 into the value. This relies on the enable bit of the mov instruction in ladder logic. Many function block instructions do not have enable bits. How would I change the value of a variable based on the status of a bit using function block programming? A real world example: You have a two position selector switch. If it is turned to the left, the drive runs at 0 Hz. (off) if it is to the right, it runs at 88.0 Hz. Or if you have a 4 position selector and want to select between 4 speeds. This should be a simple task, right? I've called the tech connect support line a few times and sent them a few emails and they haven't been able to figure it out. This is such a basic task. Thanks, Pat
