  1. Hi!   I am new to plc-programming and i need few tips to finish my first project   question 1: What is best way to convert bool's, lint, time and real into array?     question 2: What i need to have for transferring that array into company's Http/web and how to do it? modem?   Thanks for helping!    
  2. Currently have NX PLC setup as an OPC UA server and an OPC client setup and communicating.  The issue is only tags that do not have a Data Type are showing up in the OPC client.  I have 2 separate OPC softwares connected to this plc through OPC UA and both are having same issue.  If I setup the OPC as a polling service, then all the tags show up as expected.  Does anyone know if this is a known issue with Omron and their OPC UA server, or is there something that I am doing incorrectly (possibly a setting within Omron that I am not aware of)?

    Bobodopalus posted a topic in CX-Programmer

    Hi all im back to trying to get my inverter to work but this time with modbus, from this post http://forums.mrplc.com/index.php?/topic/38445-controlling-mx2-inverter-without-modbus/ and im stumped, im sure its just one thing somewhere messing it up i have a cp1l-el20 with a cp1w-cif11 and a 3g3mx2 inverter and am attempting to control it via modbus, it is wired up as follows, sp+ to RDB+, sn- to RDA-, common to the plc pin and plc output pin 100.00 to logic input 1. im using 100.00 to put it into run mode the paremeters ive put in are a1=3,a2=1, a4=50, c070=3, c071=5,c072=1, c074=00, c075=1, b27=1. im using MOV to set my speed to d1001 attached is my inv002_refresh x31 fb thanks to any1 who can see my silly mistake    
  4. Hi. I use the email block on few of our NJ101-9020 controllers to send out daily reports or any status updates. Recently the PLC's started an unknown issue and fails to send email out anymore. I use the Mail_Send function block from Omron to send emails. The only Error ID i can get is 2005, with status being "Connection to SMTP" failed. Looking at the troubleshooting guide, i cannot find anything to do with error id 2005, in fact its missing. There is 2004 and 2006 but no 2005. I've tried all the obvious thing like, power cycle, redownload the whole project, create a new instance of Mail_Send function block etc. Nothing seems to have fixed this unknown issue. Our IT department did a full check on their side and nothing seems to be out of order. I can still remote into the PLC, so i dont know what exactly is the problem. Has anyone came across this error ID before? Any ideas why this might have been happening? It was working well until few weeks ago and nothing changed and this suddenly started. Any input is really appreciated. Thank you.
  5. OS: Windows 7 on VMware virtual machine. Sysmac Studio V 1.13. What works: Ping to PLC. Sysmac Studio -> Controller -> Controller Communications -> Ethernet via hub -> Test -> "OK". What doesn't work: Starting with new project for NX701-1600 (correct PLC): Sysmac Studio -> Controller -> Online. -> Controller -> Transfer ... -> From Controller. The task seems to run to about 90% before stopping with the error:  I can't find any reference to this error in the manuals. Has anyone got any suggestions to fix this?   Many thanks.
  6. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you

  8. View File Sysmac Studio Simple PID Example A simple test program and starting values for the PIDAT instruction in Sysmac Studio. Simply run the simulator (Simulation-> Run) and toggle the Test_PID bit. Simulated feedback will allow the loop to operate normally. The setpoint can be adjusted by modifying the PID_SP variable. There is a pre-programmed data trace that traces the SP, MV, and PV. To use the data trace navigate to DataTrace0 and start the trace, flip the Test_PID bit true and the trace will log 10k samples.

  13. I am new to automation systems and devices and I just want to know how to connect two HMI's (each one would control different things) to one PLC using Sysmac Studio and NB-Designer via Ethernet. The model of the PLC is NX1029020 and the HMI's are one NB10W-TW01B and an NB7W-TW01B. I searched for info about this topic online but I couldn't find anything that worked for me, I saw an article from OMRON where they connect two NB's to the CP series, but in my case, NB designer doesn't allow me to insert more than one HMI in the same project, I also found something similar on a youtube video that gave me an idea about how to connect multiple HMIs exporting the pks file and importing it to another HMI project but I still can´t figure out how to add both to my PLC. I would thank you a lot if you could help me with this because I know it's not a rare implementation, just I haven´t found the right way to do it. I also leave the links to the Omron article and the youtube video I found. https://www.myomron.com/index.php?action=kb&article=1554 https://www.youtube.com/watch?v=rXx5lut7G9I
  14. Hi, Could anyone help me out on how to extract the digits present in a string in sysmac studio... Thanks in advance !!!
  15. Hi. I have been thru the F1 manual and the toolbox in sysmac, i cannot figure out how to convert the elapset time from a TON, to anything the NA5 panel wants to display. Any suggestion? (Want to show how long a certain step has run for)
  16. Hi, I have quite a noobie question. I want to create a function block to do some simple operations on 2 variables. Both variables are In/Outs (see picture attached). How can I make this function accept variables regardless of the data type? Given these is just simple math I am able to use the same instructions in REAL, INT, UINT, etc. But, the function block only lets me assign one Data Type to the In/Out variables.
  17. Hi. I want to get the full date and time into the plc, where i want to calculate when current step and full sequence is expected to finish and then later present it back on the screen. I tried to map the _HMI_DateTime to the controller, but it does not get added to the controller.
  18. Hi all! This maybe a simple question but my brain is not allowing me to do it. I have an array variable of INT I use for alarms. I want to compare the values in the array variable to make sure they are all zero. If they are not zero I want to turn on an alarm. I have messed with the Arrary Compare value instructions (AryCmpGTV, AryCmpLEV Etc.) The goal is to monitor all the values in the array and if one becomes greater than zero, I know that an alarm has occurred. In CX, I use 2 in-line compare statements; a greater than Zero and less than or EQ to 'some value' depending on how i split up the alarms. How can this be done in Sysmac?   Nate

  20. EtherCat Fault when..

    Stefan009 posted a topic in NJ Series / Sysmac Studio

    Hi. I have this project with NJ501-1300, in the ethercat settings we add a air valve called EX260-SEC1. When this unit is alone in the ethercat settings, it works without a problem, as expected. But when we add the servos that goes into the machine (ED1F CoE Drive (HiWin)) (Or Ezi-Servo2 ALL), then the air valve goes into error, even if the other ethercat devices are disabled.   We have tried both sysmac 1.45 and 1.47, the plc has 1.43 firmware. We have tried to create a new emptyh project and using different computers, the same error pops up when anything else than the air valve are added to the ethercat config. Any idea how to solve this?
  21. Is it possible to give a physical proximity switch or photo eye input a value to change a vfd's speed. Speed up or slow down when it has been triggered. 
  22. Hi All, I am a new user to this Forum and definitely a newbie PLC user, so I'm not sure if this is a simple mistake. I am currently trying to correct the logic (of a sensor) on a PLC program to get a manufacturing machine back up and running. This is an issue that I have fixed via PLC several times previously, but for some reason I am having issues fixing it this time. The issue that I am having is that when I try to dig into the Logic of the PLC program (Programming > POUs > Programs > Logic > ...), nothing shows up where there is typically a PLC command ladder. I get the error "No instruction in rung" next to all of the PLC program modules. I am connecting to a Omron NX1P2 CPU via laptop & Ethernet cord. To give you background on my troubleshooting process, I have verified that the I am connected to the PLC controller, by using the Windows Run program to ping the IP address of the controller. After verifying connection, I attempted to connect to the controller using SYSMAC studio. At this step, a troubleshooting window appeared with the issue "Minor fault" "Tag Data Link Connection Timeout". When I look at the Controller Status at the bottom right corner of SYSMAC, it says that I am online and connected to the correct IP address (green circle). Under that, ERR/ALM has a red circle next to RUN Mode. Ignoring the troubleshooting window, I can click Synchronization and "Transfer from Controller". A dialog box pops up and reads "...Controller does not have the POU program source...". Pressing yes to ignore this, the transfer completes. This is where I encounter the issue of having nothing show up within the path of Programming > POUs > Programs > Logic > ... . I have a feeling that this is a connectivity or settings issue, but I am not sure. I have checked my ethernet splitter (D-Link DES-105) and everything seems to be connected and working. If anyone has some insight into this issue I would greatly appreciate any help. Thank you in advance! Best cszikszai    
  23. Hi all, I am a new user of VB.net on NA Omron HMI, and I need your help to solve a problem. In my case, I have to get a HMI global variable value in VB.net, but the VariableName is in an other variable (string). For example: Var1=4 Var2=6 VarName="Var1" I worked with a "SetVariable" function to modify the value of different variables, but right now I need to read the actual value, in the example values 4 and 6.  Do you have any suggestion?

  24. connect encoder to nx1p2

  25. Hey all, I am having some issues with a Keyence IV2 camera which has Ethernet/IP functionality.  To summarize briefly, it has been configured and reading the data into my PLC (NJ501) into a structure data type.  The issue I'm having is that I cannot control this on a bit level for triggering the camera, etc.  I was reading that a Union type is the way to go, but unfortunately, I stopped getting data into the PLC when setting it up that way.  According to the configuration guide for Rockwell and setting it up in the Network Configurator, I needed to go with the SINT type.  When registering the device, the 8-bit option was necessary since the Input/Output sizes needed to match.  This was predetermined by the EDS file for the IV2. I am stumped as to how to get the data to read into the Union Type, and any suggestions would be greatly appreciated. Thanks, -K
