  1. Flip flop in structured text

    Hi all i've been trying to make a simple timer in structured text which is turned on and off by a single input, all instances of flip flops i have found seem to be 2 input. any help or examples would be appreciated example of programs; Pulse signal received, start timer Pulse signal received stop timer
  2. 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.
  3. 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
  4. 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.
  5. My timer can run when i simulate on work online simulator pic
  6. Hello, One of my client have extruder machine, which is bought from china at least 10 years. Now one temperature control module is failed and we need to replace and re-configure it with new module. OEM is out of contact, and the PLC and HMI is protected with UM and task Read Password.   Is it possible to read or crack the Password ? (CPU Model CJ1M-CPU11) 
  7. 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
  8. 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?
  9. 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...
  10. setting date cp1l

    Hi all im currently using the DATE instruction to set the PLC's date and time via the HMI which is an NB7W which i have working but i am currently setting each byte of the words being used in DATE by using numerical inputs in NB designer and entering integer and decimal to set these bits in DATE and its a bit ugly to say the least. is there a way on nb designer to only modify bytes or am i going to have to used full words on nb designer and use MOVD in cx programmer to assign them to their correct byte CURRENT SETUP always on DATE using d50=d53  
  11. 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
  12. friends, forgive me for my english.  I have a problem.  omron nt620c panel cannot access the system menu.  I reinstalled the system program through NT-SYSTEM INSTALLER.  after which I get the message: no direct information is set !!!  please use the support tool to set the pt control area and the pt notify area.  go to the system menu does not work.  I swing the corners of the screen as described in the manual.  from a video from YouTube I realized that there should be a message connecting to host
  13. Hello everyone,  Someone know, how to read timer data from omron PLC CP1E in HMI NB3Q-TW00B? I tried write macros for HMI program, but I have some error about macro in program. How I understand, this HMI model don't support data reading from plc timer TIM in cx programmer? But how I can write macros and set it for recognizing in HMI?   
  14. 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?

    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   :)
  16. 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...  
  17. 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)          
  18. 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.
  19. 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.
  20. 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.
  21. HI everyone i was wondering if i could connect a cp1l-el to 2 different NB screens running 2 different programs. we have a main line HMI which displays the health of the entire line with its own cj2m plc, we also have a machine which is part of the line that has its own plc(CP1l-EL) and HMI. is it possible for me to include the cp1l in the main lines HMI so that it can display the status of that machine? or will it cause issues because it already has a program attached to it. i dont know exactly how the NB program works does it just read the bits of data it needs to or is it constantly looking at the whole plc data list?

  24. 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!
  25. 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;
