  1. Invert scale 0-990 --> 990-0

    Hello.  I have a D word number 0-990. I would like to convert it to 990-0. So i need a function which shows me 0, when the D100 is 990, and shows me 0 when the D100=990. And of course for the between values also. Calculating continiusly. Help is much appreciated :)
  2. Hello  I try to connect my load cell via RS232 serial port 2 to PLC (PC1L-EM) but it dose not work could you please let me know what is my mistake  Thanks in advance Ebby Untitled.cxp
  3. I would like to send a character on a Micro830 using ASCII. I wish to send the character to a pc by using Real term or terra term on PC. Can somebody please let me know how can I configure the ladder diagram, I tried various commands including THE AWA, AWT and also the MSG_modbus however I can initiate the communication. I think that I am missing something cause I don't have a reference ladder diagram. Thanks 
  4. RTU Modbus CJ2M CPU34, SCU31-V1,

    Hello everyone. In my project I have to communicate Omron CJ2M-CPU34 PLC with TRANE chiller via Modbus RTU protocol. Unfortunately, I never use this protocol and I have no idea where should I start. I'm looking for examples and advices. If someone has experience in this topic please help me. I attach TRANE chiller documentation. Especially I want to use function 5,6 and 4.  CGAX-CXAX_Protocole_Datalists.xlsx CG-SVU007C-GB_0915.pdf
  5. Starting to find my way around Cx-One, running a CJ2M-CPU33, logic runs a rotary indexing-table destacker weldcell.  I am trying to figure out a way to prevent changing the value stored in UDINT TOTAL_PART_COUNT D31 when I upload a revision. The D31 increment line is section Main_Operation:40 It is a cumulative count of all parts run to date, so there is no conceivable reason I am ever going to want the TOTAL COUNT saved in an old revision to overwrite the current value.   The cell runs all day every day, so for a revision I'll open the last *.cxp file, connect to PLC, compare PC to PLC, if same I'll "Save", disconnect, make changes, save .cxp as new Rev#, and upload. When I upload a new revision, I usually (but it seems not always)  overwrite the value stored in UDINT TOTAL_PART_COUNT D31 on the PLC (which of course is bigger than whats in the newer revision since the machine has been running). Usually I remember to write down the TOTAL_PART_COUNT in the PLC before I upload and just manually change it after uploading the new Rev, but when I forget to and realize a week later, I get to have a lot of fun reading paper production logs. Is there a way to protect certain memory-areas like TOTAL_COUNT from being over-written by a Revision upload? Maybe I need to use a different memory area or instruction set? Next revision is going to be adding data-logging of faults, I'd like to create 2 arrays per fault, one for fault timestamp and one for # of minutes before the fault was cleared, and I'd certainly wouldn't want those arrays over-written with older values when I upload future revisions. Are the EM Memory Area values implicitly protected from overwrite? PS. The 13.15 "Trash Bit" contact everywhere  is from the integrator, not me, I have at least figured out the P_Off flag AS-260 IL100 LASER PARTSTCK REV23 2.27.17.cxp

  8. CP1E RS232 Setup

    Hi everyone, I am fairly new here, I have a CP1E-N40DR-A And i need to send a string of data to a printer over rs232 from the built in port on the PLC, I have had a look online and canot find any information on what I need to do. all the tutorials are for CJ2 cpus ect and the instructions that I would normally use on a CJ2 dont work on CP1E PLC's. Any help or light shed would be great,  Thanks in advance
  9. ok i have a rotary encoder to a HSC on my tm221, im converting that to ascii and outputting the value to a lascar HMI over rs232. example of value sent: 1234     value received: 2143 there don't seem to be any options to set the LSB or MSB , any ideas?? Dan

  12. Hi. Can anyone help me on how to connect to OMRON cj2m with fins or ethernet/ip protocol from windows ? Is there any vb code or javascript ? I saw an omron fins javascript  topic from patrick  but i was not able to connect with the plc.  How many steps are needed to connect ? Thank you.    
  13. Hello all, I'm using MC Protocol Format 4 to communicate with a VB6 application on a PC. I want to make some slight modifications, and I am getting a sum check error being returned by the module to my application. I believe (haha) I am calculating the sum check code correctly for Format 4 as most commands do work (reading for example). I was wondering if anyone knew of the buffer memory location on the QJ71C24N card that stores what the card is calculating for the sum check? This way I can have a troubleshooting tool to see what I am calculating wrong. I have looked through the manuals (application/basic) for the C24 already as well as the Melsec Reference Protocol manual.  I have attached the error code for reference, again, I am only looking for what the C24 calculates as the sum check code. Thanks  
  14. CJ2M Modbus communication

    Hello everyone, in my project I have to connect CJ2M-CPU34 with CJ1W-SCU31-V1 module to external device (see technical specifications in attachment). The CJ2M should read and write a few values from the external device. Unfortunately, I dont have a chance to try this communication before, just during system start. I never make any project on Modbus. Anyone can send me a program to communicate with this device, according to documentation in attachment?   38RBS_Modbus_1.pdf Modbus_2.pdf
  15. F-MPC04 RS-485 Protocol

    Hello! Anyone here know about Fuji Electric power monitoring unit F-MPC04? Does anyone have the Communication Manual for this unit? I need to find the F-MPC Protocol which it used with RS-485. I know it is accessible via MODBUS RTU, but there is already a system exist using this F-MPC protocol. It seems Fuji doesn't publish this protocol for public, but there should be a document somewhere :D   If anyone knows please kindly reply here. Thank you
  16. Hi, I've recently bought a generic RS232/TTY cable for Siemens S5 PLC. I also bought a RS232 -> USB converter to connect the cable to my laptop. My problem is that when I connect from S5 to Laptop and run PG2000, I cannot load anything from the PLC as the program gets stuck. I think nothing is being read from the converter. Please help.   Here is my setup: S5 Siemens PLC  http://i.imgur.com/kk3X7OU.jpg?1   RS232/TTY CABLE FOR S5 PLC  http://i.imgur.com/SbkD2g9.jpg?1   RS232 TO USB CONVERTER  http://i.imgur.com/Sy3C7hP.jpg?1   Thanks,
  17. G.INPUT

    I'm working on a project that reads an RF - TAG via RS232. It uses the G.INPUT command. I need some help to see if I understand clearly how it works. Now it reads a maximum of 16 digits but in the future i want to pass it to 32 bits. The command line is |G.INPUT    U5    D6500    D6800    M7922| If I understood correctly I load in D6500 either 1 or 2 to tell it which channel to read from. It stores the 16 digits in words starting from D6800 and goes on till D6815 if I am correct. My questions are: - did I understand correctly how to use the command and is there anything else i need to take care of while using it? - do I need to do additional settings to it in order to read 32 digits or does it automatically read (if the RF reader is compatible with 32 digits)? Thank you, Andrei

  23. CJ2M i/O bus error

    Hi, my company got project using omron CJ2M but we got trouble when the output is over ch10  here the PLC hardware setup  :  1. PLC CJ2M 2. PSU PA202 2. Module Input ID211 (5 Pcs)3. Module Output OD211 (2 Pcs)4. Module Output OC211 (3 Pcs) and because addtional input and output we Change modules : 1. ID211(1pcs) -> ID231 (1pcs) 2. OD211(1pcs) -> ID231 (1pcs) after the setting and upload program , warning appear for the image its on attachment. so if i want this system to run do i need to buy expansion rack or there is another solution ? Best Regard
  24. Hello, My quest is to make a memory card, which I can just put into my PLC on the field and load all program and options etc to my plc. Now i found the official omron guide about it but its not good at all... For example is does not explain that how i need to transfer the H and D memory part to the plc, and that not all network settings are being copied if im not careful.   But my question is: is it possible to make this backup memory card without having the actual plc? Because the process is done in memory card window, which is only available if you are online. So basicly i have to get all the plc rack parts to make this work? I tried with the simulator but ofc it is not working.   Someone mentioned me that it is possible he heard from someone but no one actually knows how to. And there is nothing in the omron manual as i see.
  25. Hi All I am new here without much experience of plcs. I have a PV 550 with DH485 coms port that I want to replace another PV550 with rs232 that communicated with an SLC 5/04. Is there some way to connect the two with a cable or protocol connector? Alternatively can you connect through the printer port on a PV600? CHeers   Azza
