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.

I have a very simple problem that I need help with. I have some programming experience but I am brand new to PLCs and structured text. I am using TwinCat 3 to program a Beckhoff CX9020. My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature. I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers. I need to link that value to a variable in my code so I can have the valve act on it. I don't know how to properly address the inputs and outputs. Thank you!

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

How to write a PLC program for a cycle tester
chase posted a topic in Allen Bradley / Rockwell Automation
Hi, I am a beginner to PLC. I am currently working on a home project with Allen Bradley 1100 model. The project is to build a door open-shut cycle tester. The motor I have purchased is a Bodine Brushless DC34B/FV INTEGRAmotor. My goal is to utilize the Allen Bradley to to control the motor and then the motor drive a shaft to open/shut the door. Through the LCD screen the of PLC, we can set and view the amount of cycles. I have finished the initial stage of wiring. But not sure how should I start on the programming part. Could any of you give me any hints on the programming portion? Thank you so much. -
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.

hey! I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem. I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use. I hope you can answer my following questions. 1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial? this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL) thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull. kind regards, Deuslupos,

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

hello there ! all the variables are reals ... can anyone explain why i get a different result when i calculate c2 first ??? the two programs shown in the pictures are exactly the same ... the only difference is the posistion of c1 and c2 . please help me . It's not a logic attitude in programming ..... Any ideas? Thank you

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

Multithreaded C++ into function blocks - PLCOpen
EinarM posted a topic in General Topics - The Lounge
Hi there I'm an embedded software engineer mostly programming C/C++ in Linux and have very little knowledge of the PLC environment. Recently my attention was diverted towards integrating C/C++ (Linux software) into PLC and then presumably as a function block which is supported with something called PLCOpen. Is that right ? How is multithread support in PLC in general ? and/or with the these function blocks or what ever might become instead when integrating/porting C/C++ code into PLC. The current situation is purely embedded Linux environment with open-source 3rd party userland that our code relies heavily on. How feasible is to port such environment over to PLC (given that the system supports it) ? I've been looking into B&R Automation Studio 4 and having a hard time to establish concrete feeling on how difficult/easy it is to port the code. Hope anyone can give me a slight insight into this. Kind regards Einar -

Function Block or any other method
ConfusedStudent2016 posted a topic in Allen Bradley / Rockwell Automation
Hello, I am a student that has been taught ladder logic for three years( on many different plc's ) but, I would like to learn an alternative method is there any way to convert ladder into Function Block or some other type of programming in RS logic 5000 or any other controller? If not can some one explain the basics of Function Block programming. -
Hello all, Let me start by saying that although I have been working with PLCs for 20+ years I am very (as in brand) new to the Siemens world (my wheelhouse is AB). That being said I have a Siemens S7-1500 (1511 specifically) CPU with a couple of SICK multi-turn Profi-Net encoders (AFM60A-S4NB018x12) that I need to talk to. - I am using TIA v13 with all of the updates. - I have the GSD file from SICK for the encoder. - I have no clue what I am doing - I can see the encoder values update in the watch table as I move the encoder. All fine and dandy so far... Here's where the white flag is going up.... - I am of the belief that there are existing function blocks out there 'somewhere' that can read and write to the base parameters. I have contacted our local rep who deferred me to SICK. I have emailed and left messages with them and have not gotten a return anything thus far. Here's our application... We are attaching each encoder to its own rotary gear mechanism. The rotary will need to turn in the CW direction approximately 400 degrees then return to its start point by rotating in the CCW direction by the same amount. If/When production/maintenance needs to 'rehome' the assembly, the expectation is that they 'pin' the drive in a known location then a bit would be set within the CPU that would assign a specific value to the encoder's actual position. In the SICK manual (8015078/YIX6/2015-01-16) on page 31 (section 3.6.3) there is reference to Preset control. This is what I believe we need to perform the aforementioned function. Does anyone have any examples that they could share on how to read/write to these encoders by use of a Function Block or other? Relatively desperate for help at this point. Can post test code if need be. Thank you in advance, TLAF
