  1. PIDAT INSTRUCTION PROGRAM

    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   :)
  2. 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...  
  3. 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: https://www.youtube.com/watch?v=VZxWnVn1CSY). 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 1.30.0.17. The HMI Device created is the NA5-9W00 (version 1.11)          
  4. 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.
  5. 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!
  6. Hello There I need to set up communication PLC to PLC ( R08CPU to Fx5CPU) but i dont have the modbus library for  the R08  Does anyone have the library? or where can i get it? thank you.
  7. Humming Noise in Motor

    We are using NX1P2 Controller with servomotor compatible with servo drive R88D-1SN it produces noise during operation low noise at low speed and hig noise at high speed we have 2 more axis which doesn't produce any such type of noise.   It also produces vibration in the motor.
  8. I'm using simple function block, one input and one output, like in this example: Problem I have is how to call function block and use inverted (NOT) value , ie instead 5.01 I need to use NOT (5.01) . Of course I could create new symbols that are inverted values of actual inputs but i'm trying to avoid that, number of addresses is significant.
  9. Hi there, I have a controller NX1P2-1140DT. I want to control a VFD with modbus serial communication. Can someone help me start from scratch ?

  12. Omron CJ1M CPU11 - ProfiNet - Siemens

    Hello guys, newbie here. Wait, where are you all going...? Don't go! I've got *some* experience. And a job on my hands. I've got an Omron CJ1M with a CPU11. Attached, is a PNT21 Profinet IOController. At the other end, it is going to be a Siemens SIMATIC ET 200AL, PROFINET interface module IM 157-1 PN with a couple of digital input and output modules attached. The hardware isn't here yet, otherwise I'd just jump straight into trouble. Probably. I've got it mostly setup in ConfiguratorFDT with the GSD files from Siemens. The question: How do I map the Symbols to the digital IO at the other end of the profinet? Can I just set the symbol address to the IO areas that ConfiguratorFDT show me, ie, 3300 for the inputs, etc? Thanks!
  13. Timers in structured text

    HI everyone ive decided to try and use a structured text function block for an machine output calculation, to put it simply i want the machine to say how many units its outputting per minute so i thought it would be much nicer to have a basic maths Structured text block rather than a long bit of ladder for some simple instructions. i have 2 inputs, one is the start of the machine cycle, the other is the end of the machine cycle. every cycle is one unit output. i want to time the gap between input 1 and 2 then just a bit of simple maths 60/(cycle_time) for uniters per minute. i want this to be to 2 decimal places for a reasonable resolution. the main problem im having is the timers in structured text, im a little confused how they work i would do this in ladder by having input 1 set a bit and then input 2 resetting this bit(i assume i can set a bit by using an if statement [if input 1 true, timer{bool}true]) this timer bool would then activate the timer, again how i would do it in ladder would be to have a timer1 count down from &500 then use a maths block for 500-timer1 and this would give time elapsed this is the bit i really dont know how to do in structured text and would appreciate any help in the matter. otherwise i can just do it in ladder   added my idea of what it would look like IF Cycle_start=TRUE THEN     Timer_start:= TRUE; ELSIF Cycle_end=TRUE THEN     Timer_start:= FALSE; END_IF; TIMHX(Timer_start, Cycle_timer,Timer_time); Cycle_time_bin:= 500-Timer_time; Cycle_time_real:= UINT_TO_REAL(Cycle_time_bin); Cans_per_min:= 60.0/Cycle_time_real;
  14. Hello all,   My coworker is running into an issue where his version of Sysmac Studio has been updated, but this is causing a version mismatch from an existing project.  He has called Omron, and they are saying that there's no way to downgrade the OS.    Project operating system version = 7.4.0 Device Operating System version =  7.3.0   So the OS on the NA5 would need to be upgraded to match the version of Sysmac.  Does anyone have any suggestions to revert the automatic upgrade that has occurred? Any help would be appreciated!
  15. i am trying to communication my weintek HMI with Siemens Energy Meter PAC3200. I am using MODBUS TCP/IP Protocol but i am unable to read the data register of my energy meter. Somehow i got to read the 32bit data register but still unable to read the 64bit data register of my total KWHr Energy consumption. I have also attached the manual of my energy meter. Please guide how to read all the data registers of that energy meter. Please see the page 40 onwards for reference. The manual the about 7MB so i cannot attach the file. https://support.industry.siemens.com/cs/attachments/26504150/A5E01168664B-04_EN-US_122016_201612221316360495.pdf

  17. CC-Link Protocol with a CJ2

    I have an IAI servo that was sent to us with CC-link protocol. I have never in my life used cc-link and can find very little on the topic on integrating with an Omron CJ CPU. I am curious as to whether this has been done, or is even possible given the protocols Omron works with. And if so, what did you have to do to get the PLC to communicate via CC-link. Thanks in advance for the responses!
  18. NA Data History Program

    Does anyone have any idea how I can create a Data History though the NA screen. I know I can do a Data Log with a Data Set then use a Trend Graph but, I want to create the "Table Like" Data History found in the Omron NB screen. I use data histories for a UI to an operator to review previous Cycle Times, Poka Yoke values, and Temperatures monitoring with a time stamp as to when the data was recorded. Any ideas?  I am using a NX102-9020 NA5 Screen
  19. Hello Sir/Ma'am, Hope you and your family are safe in this Covin-19 Pandemic.   One of my client have a machine in their ceramic industry which has Omron PLC System. Here I am describing the PLC Hardware Structure. (CP1H-X40-DT1-D-SC) + (CP1W-40EDT) + (CP1W-DA041) CP1H-X40-DT1-D-SC (Main CPU Unit) CP1W-40EDT (First Expansion Module, on right side of the CPU) CP1W-DA041 (Second Expansion Module on right side of the CP1W-40EDT)   Client shutdown the machine before a month due to Corona Pandemic, and today restarted the machine.   Now the problem at the restart of machine... Analog Output of 0-10V DC are not sourcing from the attached analog output module for any of channels. (Used to control speed of AC Drive) We have checked the program, and verify that the program is moving the value in analog output register address, but still no output signal at the module.(Checked Using Multimeter) We have same machine at another factory so we have tried to replace the all 2 expansion module and observed that the first Digital Module is Working properly but only last analog output module is getting problem again.   I don't know much about OMRON PLC Programming so seeking for the help regarding this.   OEM have moved the data in CIO 106 for generating analog output, as well OEM has move #8099 in CIO 104 and CIO 105 at the first scan of program. I don't know very much about this programming, that's why i refer some manuals but didn't succeed yet.   Kindly help me out if possible... I have attached backup of program as well for reference...   Thanks...   Bobin Feeder.cxp
  20. NB screen freezing

    Hi all has anyone ever come across a NB series screen freezing when a screen change is attempted? i have a NB7W which when told to change to screen 58 or 59 via a function button or via a PLC instruction it freezes the HMI and it needs to be restarted. have i hit some screen limit or something? they only thing i can really think of it has too many graphics, it contains 6 bitmap images and about 12 graphic buttons/lamps
  21. Hey guys, I am having and issue trying to connect a NS Hmi to the current setup that I have installed. My processor is as CJ1G CPU42H. It used to communicate with 2- NT31 via Nt-AL001 module. I had one NT Hmi that faulted and I am trying to replace it with a NS10 model. I am aware that the ports on the NS are RS232's. I installed a NS-AL002 in port A and assigned the appropriate dipswitch settings. 1-ON 2-3-OFF (4wire) 4-On terminating resistance since it's the last HMI in the loop. HMI Project comm Settings are NT Link (1:N) Comm speed (I tried both High and standard) Unit# 1 (tried to change that as well with no luck) On the first HMI (NT) I get Comm port B Receive error when I turn on  HMI#2 (NS). Every time I tried a different setting I made sure to restart the PT. Any suggestions would be greatly appreciated! Thank you.    
  22. Mitsubishi Fx5uc

    hello everyone, Im new with mitsubishi and  ive got a project with a Fx5uc but im stucked in communication protocol to communicate with a weintek HMI ive already tested easybuilder simulation with a modbus tcp ip symulator and it works but im completlely lost about mitsubishi, is there a way to communicate via Modbus TCP/IP? or which protocol would u recommend as i have to connect 2 drives as well. thank you in advance
  23. Hi All, I've some problems after converting a cqm1-cpu41 program to a cj2m unit. I am still trying to identify all problems  but the most annoing at this moment is the following. This cpu is connected to a proface HMI, and commands the screens that are shown,  through D1. I am keep getting screen #9 ("press reset"). if i press and hold ALARM_RESET (0.07) and the timer hits, I get the main screen that i want.But after releasing ALARM_RESET (0.07) screen #9 is back again (so that value is wriiten in D1)   This is a snippit of the converted program (exactly the same as the old program) There isn't any other code writing #9 in D1.  The strange thing is that line 210 is doing exactly that ( IF NOT ALARM_RESET (0.07) -> MOv #9 to D1 ) what is see, but how in earth did this work in the old CQM1 unit ? I suspect something with cycle time ? Maybe in the old unit line 217 was executed later and #A was written in D1 'over' the #9. Anyone has some thoughts on this ? Thanks in advance  Jeroen  
  24. Hello, I need to make communication NB TW01B by Omron with Siemens's S7 1200 PLC using MODBUS TCP. I did everything like in this manual: https://www.myomron.com/index.php?action=kb&article=1566 I can read and write single bits from and to DB but I have problem with representation of float variable. In hmi_variable.png you can see my DB. Every BOOL variable communicate just fine the real ones doesnt. In NB - variables.png you can see how i added them into NB panel variable table. Settings.png shows settings of my INPUT number element on the frame( screen in NB). When I write on panel for example number 10.0 then from the panel view it looks properly but in PLC you can see value like in the 10.0.png. What am I doing wrong? Any suggest? hmi_variable.png NB - variables.png Settings.png 10.0.png
  25. is there a way of stacking screens in NB designer? ive asked question similar in the cx programmer forum but it might be better asked here. for instance if i have a program that displays an error screen when lets say the motor is overloaded but then the air pressure is also  cut off so that screen then pops up, we currently have a system that states when there are no errors to display the main screen with a DIFU command. however this system doesnt work very well if multiple problems occur it will only display the most recent one and when that is fixed the screen will not change. is there a way to make screens "overlap" and be able to close them individually or just any methods you have used that might be better at controlling the screen for this sort of application? thanks anyone who can help
