  1. Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use   My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI   I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling   Tom
  2. Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks

  4. Hello to everyone! Our company is trying to make a quick disconnect for motors that connect tp servo amplifier R88ND-1S. As I know Omron doesn't have any options to do it or make an extension cable. Does anyone tried to cut the cable and make custom connector? If yes, could you share your experience? I'm afraid of having issue with encoder count. Thank you in advance! Scotty.

  7. hello expert i want ask some help So i tried to communicate my Omron PLC (cj2m cpu31) with SCADA from Schneider (power logic) on my omron side the comunnication on PLC already take to communication to NB so i add communication module CJ1W-SCU41-v1 I want asking how to open the communication if i want the scada become a master and my plc become slave i got this from omron website is that program compete for my case? i need configuration for scu41 module also to communicate or if you have suggestion i really open i just need to open port RS232c from scu41 so scada can read the data from my plc  tahnkyou for your help
  8. Ok so I recently got the Factory i/o software to practice plc programming more in depth.  I got it working easily enough with the siemens TIA software and I am now trying to get it to work with the Omron Sysmac Studio software.  I am not sure if it is possible or not.  I have access to the hardware but I was really hoping to use the simulation like I can in TIA.  Any insight would be appreciated on the subject.

  11. Hi all is it possible to use the internal date of a plc in a function block without setting it as an input for the function block? for instance i have some logic to do something inbetween lets say 10:00 and 16:00 o'clock am i able to use those internals bits of the plc where the time is stored without inputting them to the function block and using them internally?   thanks
  12. LD-105CT - Change goal location

    Hello. I'm currently working on a LD-105CT.   Is it possible to change the location of the goal, when the robot failed going the specific goal? And is it possible to perform a new task when the robot received an error message/failed going to the goal? Ex: Pick up cart at location A, drives to location B(Location already has a cart in place) and then change goal to location C(which is available) and then release the cart at location C?
  13. Hello there, I am new to OMRON so need some help to communicate two PLC over FINS.   Here are the description of the system... (IO Table image is attached)   PLC1-  CJ2M-CPU33 IP- SUBNET- UNIT NO - 00 (set the dial available on the CPU in HEX) NODE - 22 (set the 2 dials available on the CPU in HEX) PLC2-  CJ2M-CPU33 IP- SUBNET- UNIT NO - 01 (set the dial available on the CPU in HEX) NODE - 23 (set the 2 dials available on the CPU in HEX)     Now, what i have to do is to transfer the D100 to D110 from PLC1 to PLC2's D200 to D210 and Transfer the D100 to D110 from PLC2 to PLC1's D200 to 210.   I have tried RECV and ECHRD blocks but didn't succeed yet.   Two CPU are connected over ethernet via a industrial switch.   Can you help me to achieve data transmission please...
  14. inv002_refresh scanlist

    Hi all Can someone please clear the scanlist value up for me which is part of the INV002 function block the documentation says that whatever nodes you have assigned are what bits you need enabled in the scan list they give the example of node 1 and node 14 being used from this they get a scan list of #4002, where does this number come from? for my next job i will be using 3 inverters and am not sure what my scanlist should be
  15. Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8  = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR    this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000   any help will be greatly appreciated.

  19. Hey everyone, I have a CJ1M PLC with a CJ1W-SCU21-V1 serial card. It is unit 6 and I am using port 1. I have bit 1659.06 ((1500 + 25 * Unit #) +9, bit 6) as "characters in buffer" but it never comes on (data is being received through the port successfully). It is on No-Protocol mode. Does anyone have any ideas as to how I can detect data in the buffer?
  20. CP1H Modbus issues

    From @Janaka Angampitiya: Hello, I have Three CP1H PLC with Cj1w scu31-v1. I need to send a Modbus command SCU unit through Modbus RTU compatible power meter. I use instruction TXDU and CMND but it's not working. My PLC Arrangement CP1H PLC  - CP1H-X40DT1-D    ver. 1.3 Option Board 1 mounted Cp1w-CI41   to NB HMI its work Option Board 2 Mounted CP1W-CIF12-V1 to PLC 1, PLC 2 and PLC 3 between communication Serial gateway mode it is work.

    Hello PLC Users, I have recently final year project for my college. And i make PID instruction to control pressure and used VFD to control the pump. also used 4-20mA for Pressure sensor and 0-10V for VFD. But, i don't know how to use PIDAT instruction, please help me to understanding PIDAT Instruction, or do you have example ladder for my problem. Thank's   :)
  22. Hi everyone! I got this machine with a CP1H PLC and NS8-TV00B-V2 as PT. I was told that they were working fine, but suddenly, It appeared a communication issue: black screen and "connecting..." at right bottom. I dont know if It is a configuration problem or some hardware damage.  These are the configuration in the PT and the PLC. The communication is through RS232 Serial.  I tried to communicate another PT screen with the same communication settings and IT WORKED!. ' I've been thinking that, perhaps, the serial port A is damaged, I have tried to set port b, but I havent could. How can I configurate PORT B??   THANKS...  
  23. Hi all:   Hope somebody will help me with the below error encounter on the NA. I mapped a external device (NJ PLC) variable (which is a structure) to a NA Global variable and the structure is automatically created in the NA data type as expected. I then create a new NA global variable and defined its data type as the auto created structure. However i observe the created new NA global variable is highlighted with an error "a data type cannot be used by both mapped and unmapped variable ....." ( pls refer to the attached screen).  I have found and view on the Youtube this video :"Introduction To The NA DataTypes" (link: that clearly show the "imported" structure can be used for unmapped NA global variable even there is some variable already mapped to external device variable (starting from the 3:50minutes mark of the video). In my NA program i would need to create such unmapped variable for my logic use. Also i observe that i was unable to delete the auto created structure from the NA Data Types even after i deleted all variables that are defined with that specific structure. How can i delete such auto created structure in case i want to clear off some of those unused data types. I am using Sysmac Studio version The HMI Device created is the NA5-9W00 (version 1.11)          
  24. Help Program C40P Using Computer

    Hi Mr. PLC Members, I have two Omron Sysmac C40P PLC units with no programming units or connecting cables, I need to connect and program them using normal computer. I searched the form to find the software as SSS or LSS and the cable as 3G2C7-LK201 and the programming unit as C200H/PRO27 console. Is there any way to connect the C40P directly to the computer and program it? What do I need for this? -hardware and software- I know they are old nowadays, also I am not sure if the needed hardware is still available. Thank you in advance.
  25. Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help!
