  1. PID regulation PT

    Hello   Does someone have a good way to control pressure using PID in cx-programmer? I got two pumps and one PT(4-20mA) Half the year only one pump need`s to run (about 3bar)  but in the season (i work in a fabric) two pumps need to be running (about 4bar needed) except in the night. I`m going to use HMI for adjusting the setpoint so there is no need for any clock/date for this to change itself. The question is how to get one of the pumps to shut down when the need for pressure is not so high. And get the pumps to change "main" pump sometimes so one pump is not running all the time.   Hope this was understandable    
  2. Hello guys, I need help. I have an OMRON PLC; CJ2M series which I am not very familiar with. I need to do comparisons, but I see that do that I can't just compare with a value. It looks to me that I have to store the value I need to use to compare in a memory address and reference to the memory address for my comparison.  Is it possible for me to compare using a value and not have to first go through a memory address? Is there a way to use the instruction to store the value in a memory location ? Or do I specifically have to use CX-Designer for me to wrote the value to a memory location? Thanks in advance.
  3. Omron CJ2M - Wago remote I/O

    Hi there, I’m not sure how familiar most of you are with Wago remote I/O, but I hope you may have some solution for the following connection problem I’m having. I’m working on a project to modernise an old folder collecting machine for which I’m using an Omron CJ2M Cpu33 together with 8 Wago 750-352 remote I/O units over ethernet/ip. These Wago units all contain two 8DI digital input cards and two 8DO digital output cards alongside a 750-610 bus power supply card. Adding them to my network in CX network manager is no problem and all seems to work fine. That is, as long as I don’t physically add the bus power supply card, which I need to, well.. power the Wago bus. Soon as I add this card (which was in place while making all the necessary settings to the Wago and Omron units) it just won’t connect. Remove it and it connects like it should. As far as I know the power supply card has no I/O addresses or other communication functions whatsoever, so I can’t get my head around it. Even stranger is that when instead of it I add an analog input card, with bus power connections build in, it connects without a problem. The .eds file only contains info about the main Wago unit, after installing it I should be able to add any kind of I/O card and address them in the Omron software. Also, the supply card is added and visible as a fifth card in the Wago I/O settings and the I/O status led is green during this error. Therefore I would say the problem is at the Omron side. Any sugestions?   Thanks in advance Andy - The Netherlands  
  4. Programming Analog Outputs - Problems

    Hi All, I've been perusing this forum and I've seen this topic covered before, but I still can't make heads or tails of how to do it still. I'm trying to vary an analog output 10v signal to talk to a VFD according to how much time a certain input bit is energized. Currently I have it set up as a totalising timer, trying to move the PV into a word so I can use it to scale an appropriate output. The trouble is, I'm not having any luck getting the output to do much of anything. No errors show up. For reference, I'm using a CJ2M CPU 12 PLC and the output I'm trying to program is a DA042V, its in slot 05 of the main rack. I'm trying to scale a 0-20 time to a 0-10V signal out. I used to have a problem and I was getting ~-.5V out of output 1, but I enabled a bit and now it's hanging out at 0V. Clearly I did something right. Any help would be much appreciated. I'm sure it's something silly, and I'm new at OMRON PLCs.
  5. version incompatible

    I'm supposed to send the software from one machine to the other. The Dwonload but who does not want to open with the CX Programmer: comes version incompatible. But I do not want to pay 700 € for an update I just want a tool that allows me to send this data in the other machine. Weir has an idea or who helps me I pay the service. The machines are in Austria in Saint Pölten.
  6. CX-Simulator

    Hi guys, Do you have experience or know any good guides to set up a simulation case like this: - Simulating a PLC program such that the "PLC" is accessible on the Ethernet (for example just locally). - In addition, setting up the PLC settings with FINS protocol such that it is possible to write to the PLC with FINS protocol from another device. The first part is  most important. Best regards PC_VS_PLC
  7. Program help

    So I need some help with a program I am currently making, and wodnered if there was an easy way to make it. The function I need help with is this: There are 4 pumps, and 1 of them is going to start, after 10 sec shall the next start, so 10 sec after that the third one. And so like this it continues. But heres the clue. The pump which have been used the least is going to start first, if it is pump 1 that have been used the least, or if pump 3 has been used the least. If you know of any function block, or other way I can do to make this work, I would love the help.   (I know of the comparison blocks less than and more than, but with these I only can think of 1 way to make this work. And it would be over 48 function blocks, which I personally think is too much)
  8. "This type of PLC is not supported", this is the error which appears when I try to connect cx programmer V9 to CJ2M-CPU11 using a USB (A type - B type) cable. Please help me resolving this error.

  10.   Hello, I want to regulate the temperature by a thermocouple type T with an OMRON control module TC001 / 2/3 and a CJ2M CPU14 series PLC using CX-Programmer as a programming environment. Could you provide me with an example project? Thank you for your help.
  11. I have project where I need to measure motor current but I do not need to control the speed of the motor since it would always be running at full speed. Do I still need to use VFD to get feedback or is there cheaper way to measure the current?
  12. Hello. I have some issues with starting cx-programmer. It wont start. The start up screen shows, then closes, says that cx-programmer is running, but it is not, it is an empty window. When I look in task manager it says the program uses 0% of the processor, but it uses ram. Do you have any idea of how get the program to start the program again.
  13. Hello, is there a way, to edit E5CC-T temperature controller internal program, using CP1L-EM PLC, connected to temperature controller via rs-485 communication? I can't find any information about doing it. I know that i cat change these programs, using CX-Thermo, but that is not an option. I need to do that, using only PLC..
  14. I want to unify my programs and select only configuration words (the same program for many applications) . My problem is with the assigned outputs by the high-speed pulse output like PLS2, ACC, ORG ... I thing that the instructions JMP/JME may allows to use these outputs as normal outputs when HSPO functions is not required. Is it right ?
  15. CJ1W-TC102 Module Troubleshoots

    Hello Everyone. i'm in charge of a biodigester working with an old siemens plc, but today i recieved a cp1h-xa40dt-d with the CJ1W-TC102 temperature module. I need to migrate the programation of the siemens to the new one, but CX-Programmer isn´t so much familiar to me.  Basically, the old plc turns a mixer each 20, 30 and 45 minutes and i wanna make the same for the new one, adding a resistance for monitoring the temperature inside the digester. Do you have a program for me to check it out how it's done? I have the source code of siemens, idk i this could help.
  16. All, I am looking to hire either a full time PLC programmer or contract programmer that will develop systems in Ignition.  Experience with Ignition is preferred, but if you have other experience that is related, that is also acceptable. Python scripting is prevalent throughout Ignition, so that experience is required.   PLC knowledge is required. ERP system knowledge would be a major plus, as well as how to connect Ignition to it. All are SQL based.  
  17. On-Off Temperature control

    Hi, i'm actually working on a project with a CPU33 CJ2M and a external analog output CJ1W-AD04U I'm trying to read the informations coming from a PT100 sensor and control a valve which act on the temperature. i'm kind of lost in this project because it's my "first time" with Omron ! Which function block must i use or how must i program this would you show me example ?  Thank you for the help guys.
  18. CJ2M-CPU32 and CJ1W-TC002 help

    Hi everyone. l have a project with omron plc but l dont know omron. l have CJ2M-CPU32 and CJ1W-TC002 also input and output units. do you have a example temperature control programme for this device ? 
  19. Hi   I'm all new to using omron but "stuck" with a project. I find the CX Programmer software (version 9.35) a bit confusing. Used Siemens a lot.  What I'm trying to do is to display date and time on a HMI showing cpu startup time. I use a "First cycle flag" that triggers once when CPU starts and then I understand that the date and timestamp is in the system variables A352 and A353. But how do I format them as a normal text? I only manage to display them as #hex-numbers. I have tried googeling but have not found an answer to my questions. edit: CPU type is: CJ1M CPU12 //Morten
  20. I'm looking for some general information about different types of vibration/temperature sensors. What type, brand, model number, etc. will best fit my application.  Scenario: I want to monitor the vibration and temperature of multiple motors and gearboxes for a large overhead conveyor system. If an oil leak occurs and temperature increases, I want to see a temp. alert via a HMI. If a something mechanical fails, I want to see a vibration alert via a HMI.  I've looked into sensors that stick to the outside housing of the motors or gearboxes via a magnet. My concern is justifying the temperature readings. How accurate would a sensor that reads an "ambient" temperature be (compared to a thermocouple on the motor coil itself or some sort of probe)? Also, would the location of the magnet  on the motor or gearbox drastically affect the temp. or vib. readings? Has anyone had success with a similar setup? If so, what devices did you utilize? Are these systems truly beneficial?  I'm currently considering Banner's wireless products...
  21. Hi, Recently, we replaced our old digital temperature transmitter with a Baumer Flextop 2201 digital temp transmitter. The application of the digital temp transmitter is for a hydraulic press and the output is fed to the Siemens S95-U plc. The Flextop was able to react properly promptly when there is increase in temperature but whenever there are sudden drops in temperature it is slow to react. The analog transmitter (dial) was already at 25 C when the hydraulic press was shut down while the Flextop was still at 35 C. We used a three wire configuration for this. Does this have to do with our wire configuration? I know there are 2 wire ,3 wire, and 4 wire configurations for 4-20 ma sensors but I'm not sure what are their differences among them. Please see attached configurations below.     Thanks,
  22. Hi everyone, now i am doing a project related to communication between c++ and Omron PLC CP1E. Anyone have a way to connect the cx programmer and visual studio c++? Thank.

  25. where are the FB libraries

    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!
