I am noticing a problem where i am using MOV instruction and writing literal text into source and String datatype in destination. It works fines in one program but doesn't on another it show an error Invalid Data Type. Argument must match Parameter Data type. I know what the error is and why but my question is why is it working perfectly fine in 1 program and not on another.

Hi guys, I am having difficulty in understanding and implementing the scaling of 32 or 16 bit binary data using Mitsubishi DSCL2 instruction. I just don't understand what to pass in its parameters particularly s2 parameter. I tried many variables but I get errors. Please can someone provide an example how to implement that and scale any float no, for example 1200.00 to 100.00 using this instruction with output scale 0-100 being 100 at maximum for the sensor value of 1200.00 I am attaching pdf for DSCL2 instruction taken from Mitsubishi manual for help. and the error I am getting on my melsoft. instructions_manual.pdf

Hey guys, last week I posted part 1 of a series of OPC UA articles in Node-RED. That article covered some important concepts of OPC UA and how they relate to building your own server in Node-RED. I then walk through an example OPC UA Server flow and show how to successfully deploy it. https://flowforge.com/blog/2023/07/how-to-deploy-a-basic-opc-ua-server-in-node-red/ In this second article, I create a more practical example, and show how to build a custom OPC UA Server for an Allen Bradley PLC in Node-RED, including how to encrypt the server connection with SSL to make it production-ready. https://flowforge.com/blog/2023/07/how-to-build-a-secure-opc-ua-server-for-plcs-in-node-red/ I did my best to break everything down into manageable details, so that hopefully even someone with minimal experience can follow it. But ultimately building a custom OPC UA Server does take some effort. My hope is that this tutorial can teach someone enough concepts to go on and develop their own custom OPC Server applications to suit their specific use-case. As always, if you have any questions please let me know! Here to help. note - the full source code is included at the end :). Let me know if you have any questions! -

Hello everyone, I want to use my own computer as plc. I have a molex brand SST-PB3-PCU SST card. I will connect my I/O modules to the profibus adapter, then I will connect the adapter to the SST card. Can Codesys see this SST card and if so how do I make the connection. I can connect this type of connection in the InControl (an old software) program that I used before. Please Help Me!! The Board I use to connect the I/Os to the computer: SST-PB3-PCU Profibus Adapter to which I connect I/Os: 1794-APB | Allen Bradley PROFIBUS Adapter Module My I/O Modules: Allen Bradley 1794-IB16 and 1794-OB16 My OS: Win10 64 bit Codesys Version: CODESYS V3.5 SP18 Patch 3

Hi, I'm quite new to the PLC programming, I saw this delay input in one of the videos, that automatically switched to 1 after a set time, it wasn't a timer, just an contact input with time delay

So im looking for recommendations on a safety PLC application, and I'd like some advice. So the addiction is zero motion detection, were using a 5069-L306ERMS2, 5069-IB8S, 5069-OBV8S. What id like to know if its feasible and safe. Can a zero speed detection code be written and safe in a PLC? I mean you can buy a zero speed detection safety relay, and two generic sensors , one PNP, and one NPN, and its just watching the pulses to happen in a predetermined manor and that both transition in the correct manor and that they both stop. So why or why not do this in a PLC? Any advice on how to do it, and considerations or advice? What are peoples thoughts and or advice?

I have a problem trying to scale a floating number coming from an HMI to a value to use on PID instructions.My problem is on the scaling instruction.Whenever i try to run on cx simulator it gives me an error My setup of the scale parameters are (using SCL3(487)) D616 #0000 D617 &350 D618 #FFFF D619 #FFFF D620 #0000 My ladder to use the float number is: *F(456) Value +10,0 D2120 FIX(450) D2120 D2062 SCL3(487) D2062 D616 D2072 The error that throws is 0x80F0 Thanks in advance for any help PS Also tried all Scaling instructions.I think my problem is the setup of parameters for scaling instructions

Hi there! I recently discovered this forum and I find it pretty useful for sharing and learning about PLCs. The thing is I'm trying to make a Stack using the SSET(630) instruction in a CJ2M PLC. Reading Omron's W340 manual I saw that PLC memory address for the different stack channels is represented as "00010000" to "0001000F". So, in order to set the last stack word address as well as the pointer's address, how do you know those values? Or am I just misunderstanding something? Thanks in advance! Edit: Solved, the definition of the stack was wrong!

Hello Expert, I've problem regarding Instruction RS2. I can receive and send data, but my problem is each time I send data it will always add 0 at the back. I define array data for sending: POU_01/DATA_SEND[0] 769 00000011 00000001 H0301 -- #0301 -- Word[Unsigned]/Bit String[16-bit] VAR D2235 %MW0.2235 -- POU_01/DATA_SEND[1] 0 00000000 00000000 H0000 -- #0000 -- Word[Unsigned]/Bit String[16-bit] VAR D2236 %MW0.2236 -- POU_01/DATA_SEND[2] 2560 00001010 00000000 H0A00 -- #0A00 -- Word[Unsigned]/Bit String[16-bit] VAR D2237 %W0.2237 -- POU_01/DATA_SEND[3] 50637 11000101 11001101 HC5CD -- #C5CD -- Word[Unsigned]/Bit String[16-bit] VAR D2238 %MW0.2238 -- Data receive on Serial Terminal : "01" "03" "00" "00" "00" "0A" "CD" "C5" "00" ==> "00" last value I tried to figure out how can it get there ? I already check for terminator character already set off. I use channel 2 using FX-485-ADP-MB. I set my serial D8420 ==> "0C81".

So I'm having trouble writing a FBD within my current program for a slitting line. I need to keep a constant tension on my web as it is being recoiled onto our recoiler. I wrote a simple program using a sensor to read the growing rate of the coil to get a radius and I have feedback on my torque on the recoiler motor. The simplest math for this application without getting into anything too fancy should be Tension(lbs)= Torque(ftlbs)/coil radius. only problem is when its less than a foot then my calculation is thrown off and it actually shows tension goes up until it reaches the one foot mark then it seems to scale correctly. Do I need to scale something else? Any help on this would be appreciated.

A little background information here, I am trying to create a moving average so I accomplished it with the code (imaged attached) The problem i am having is the AVE instruction error bit goes true. it leaved me with a result of 1.#QAN I did some googling and it said this is typically done when dividing by zero?? so i added a NEQ to 0 prior to loading the array. then it happened again. so i put the error bit in front of the FFL so it will stop loading the array when i get the error bit so i can see what values are in the array when it errors out. Has anyone else had this issue and what could you do to resolve it? I haven't had any luck find something that points me in the right direction. Thanks in advance for your help.

Powerflex 527 rotating after MSO instruction
Jiggadoo posted a topic in Allen Bradley / Rockwell Automation
I am controlling the powerflex 527 drive with MSO instruction, first setting the drive on and then running the motor with MAJ instruction. After MSO instruction, motor is rotating about 2 sec and then stops to wait the MAJ. I have not find any solution for this. My configuration is frequency control, no feedback, sensorless. One hint i found from the rockwell pages but it did not help me. Rated slip speed is set to zero. -
Hello everybody, I have the following situation: I use the MAM function to move a servo axis; It also moves and stops correctly when the condition before turns flase. The result is actually good, except that sometimes a readjustment takes place (but only disturbs as I said sometimes). I have been sitting in front but didn't notice anything, only the Operator meant that this happens sometimes Now I would like to know how this can be stopped. Thank you What information do you Need to help me further

Hi all I have a project where i am building a bread softness tester. To do this i am using a smc electric actuator and an A&D scale. The electric actuator will push down on a slice onto an A&D scale. A micro830 plc is then reading the data from the scale and storing the real variable in an array 80values long. I would like to display on the hmi (panelview800) the peak/maximum value in the array. I am struggling on how to do this though and have not found much information online. any help would be much appreciated Thanks in advance Trevor

HEY, I'm kinda working on my own label machine and i am stuck on deriving its speed. I have already set the interrupt and acceleration parameters. but the problem i am facing is that i can't understand the ddvit's output pulse and output frequency relation to speed. If you guys know something, please do help. thank you,

Hi Guys! I have a problem. I have a leaser sensor, I already set the sampling frequency to 0,1 s. So 1 second I will get 10 data. I need to use the average of the datas. My problem is I dont know how can I solve that, after the 10. data every new data I have to recount, the last 10 data's average. I think maybe I have to use the FFL instrucion or something like that. I need to solve this problem in ladder diagram. I use RS-logix 5000 software. Anyone can help me? Unfortunatelly I havent the the software, so I cant show you what am I think. Maybe the sliding window solution is the right, or is it not related to this? Im a bit confused.

Hi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088). I want to turn on a permissive if the compared word is between 1 and 12. Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual???????
