  1. CP1L PLC network communication error

    Hello all,   I have a master PLC(CJ2M) which is communicating with slave 4 slave PLCs(CP1L). one of the PLC have communication error, upon checking in cx-intergrator it shows that all the other slave PLCs and other components are connected to network-1 and faulty PLC is connected to network-0. Unfortunately, I couldn't change it as cx-intergrator doesn't allow me to change download the changes. So anyone can please help me with this issue. If you know the troubleshooting way then please reply.    Thanks in advance.    -Yash
  2. INDIRECT REGISTER

    i want to use indirect register, but why contact 100,IR0 is not ON, is it my program correct?
  3. I have been attempting to connect to connect to a couple of PLC's that are in some of our slide gate conveyors (CTI). I do not have a lot of experience with PLCs. Took a class on it a few years back, but haven't had much hands on experience since. So last year we had a technician come in and add a rung to the program of the CPM2A that allowed the PCB to hold at the out sensor and for the incoming machine to not accept the board until the conveyor is fully extended. What I was tasked with was checking the program in the CPM2A and applying that additional rung to the CPM1A on the other line. Unfortunately I cannot connect to the 1A and when I attempt to connect to the 2A it tells me that I am trying to connect to a CQM1 instead, but that's not what the PLC physically shows it being.  I have the CS1W-CIF31 cable and the CPM1-CIF01 as well. I am using the correct port (COMM4). Port settings are 9600, 8, even, 2. In CX-Programmer, I am clicking New > Device type (CPM2A) > Network (toolbus).... When i connect to the 2A it tells me its a CQM1... SO when I change the settings to that one and compile the program it shows me a very weird program. Doesn't seem to have any real instructions. Maybe I don't understand the program?  When I try to connect to the CPM1A-30CDR-A-V1 I just get a failed to connect every time. I Open CX-Programmer, New, Device type (CPM1A), Change CPU settings to CPU30, toolbus, etc.... Failed to connect. I have been trying to figure this out for a few days now and haven't gotten very far. I have tried to connect with Omron and haven't gotten far from there. Any Help will be appreciated, I'm very noobish sorry lol

  5. CX-programmer IO list

    Hey. I have a PLC program I need to customized to a diffrent PLS (CP1L).  PLS ony support CX-programmer.  I miss the I/O list. Are there a easy workarund here, to find out the IO list ?    Best regards Wictor 
  6. Hello there, Today i have commissioned my first project with OMRON make PLC. Model: CP1L-EM40DT1D. (CX-Programmer) I have 2 built in 0-10V Analog Inputs on the plc. for analog input no-1 i get the digital value of 0-1000 in specific plc register address corresponding the 0-10V. (Factory setup) But today on site, i have noticed that some miner value of 0 to 50 is always coming and fluctuating very fast in that register, however the transmitter are genetaring 0.0V only (I have checked using digital multimeter with high precision) PLC and Transmitter are already grounded and all the cable connections are tight as well. so how to overcome this high fluctuating value ? is there any setting to filter the input ?
  7. Is their any method like virtual port adding to advanced HMI and cx programmer to view input and output from advanced HMI to Cx-programmer.?

  9. SLC 5/03 rs232 connection problem

    I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?

  11. Hello everybody, I continued my project this morning and my HMI gives the 'PLC No response 00-02-3" error... I haven't changed anything since last Friday, so in theory it should work. I used this tutorial a few weeks ago and that worked. I also tried so use some old programs which used to work, but they don't work now...  HMI IP: 192.168.250.1 (the addresses from the tutorial) PLC IP: 192.168.250.2 (the addresses from the tutorial)   Does anyone know what could be the problem? I already tried using another switch, but that didn't work either. EDIT: I just saw that I posted this in the wrong subforum, excuse me EDIT2: I found the solution. I cleared the data memory before... So what I did was transfering the settings to the PLC, then completely power off the PLC and then power it on again. That worked for me! Thanks, Olivier
  12. 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  
  13. Hi there! I recently discovered this forum and I find it pretty useful for sharing and learning about PLCs. The thing is I'm trying to make a Stack using the SSET(630) instruction in a CJ2M PLC. Reading Omron's W340 manual I saw that PLC memory address for the different stack channels is represented as "00010000" to "0001000F". So, in order to set the last stack word address as well as the pointer's address, how do you know those values? Or am I just misunderstanding something? Thanks in advance!   Edit: Solved, the definition of the stack was wrong!    
  14. Help please

    I got a new cpm2a and installed cx one (programmer) on my dell XP and tried connecting it but failed. I’m using the peripheral port (serial to usb (cif02)) and also made sure my drivers read this cable correctly but when open my cx programmer I choose cpm2a* and when try changing the network type to the USB port, it doesn’t show up at all. Idk what I’m doing wrong. Please help

  16. Hello guys I am a beginner in FINS TCP communication and I am trying to do a FINS TCP communication between an omron PLC CP1L-E in client mode to communicate with my PC that is in server mode, I am using the SocketTest v3.0.0 program that is in listening mode and still was unable to receive any information from the CLP, can you help me? The program and some images of the simulation are attached Thanks for reading SERVER PC IP ADDRESS 192.168.15.160 CLIENT PLC IP ADDRESS 192.168.15.10 tcp socket_vms.cxp
  17. 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?
  18. Hi all I was being really clever and suggested i add a list of preset settings to a line which every1 seemed thrilled with. however the amount of tedium has just dawned on me. im hoping theres a better way to go about this. the main idea is that we have a line controlled from a cj2m which has around 150 changeable settings including things like conveyor speeds, pump filling times.. waiting times etc.. i have done this in smaller scale before where we had changeable pumps, when pump 1 was connected i used the MOV function to load pump 1's data into the correct words. and in NB designer i had layered multiple number input boxes each displaying only when its own pump was connected. any ideas would be great

  20. Pressure transmitter drift

    Hello all this isnt strictly omron/programmer but has anyone used much in the way of pressure transmitters? we have a wika s-11 pressure transmitter on one of our machines installed roughly 7 months ago where the scaling does not seem to be linear, i only started working here around that time so i dont know how it was installed etc. but its a 0-40 bar 4-20mA transmitter connected to an ad081 4000 resolution connected to a cj2m. so the conversion should be nice and easy 100 raw data = 1 bar however it seems to be scaling logarithmicly to me as we checked with a 2 different guages and when they were at 2 bar the transmitter was showing 137 raw data and at 8 bar it was showing 737 raw data and this seems to keep scaling in this fashion as we get to higher bar. is this a common fault on transmitters? is there anything else that could be causing this? how often would you normally expect a transmitter to last? i checked my scaling FB on another transmitter connected to a compressor and it worked correctly so its not the maths used   thanks in advance
  21. Hey all, Further to my other post I need to read an analog input flowmeter signal (4-20mA) and scale it to litres per minute flow-rate. Then display on HMI...... Then use a PID control block to control a output water control valve (4-20mA) to a calculated set point (litres per minute) The flowmeter is measuring water flow in a pipe & The control valve is controlling the flow rate in the pipe. The water is then sprayed onto a conveyor belt - measured at a percentage SP depending on the amount of powder product on the conveyor belt (in KG) 1. So inputs to PID is the SP (litres per sec) calculated every few seconds from product weights (kg) in bins. 2. And the PV is the flowmeter reading. 3. Output is the control valve (4-20mA)  Does anyone have any tips to do this or some good flow PID and flowmeter example. Your help would be much appreciated. Thanks Richard                           
  22. CPU to Advaced HMI slow response

    HI all,  I have connected my CJ2M-CPU13 to Advanced HMI software via Hostlink (19200,7,2,E ) .  I connected to the serial port in CPU and just used ( didnt write any code or formating).   The HMI response is very slow ( almost 2+seconds).  I am not sure whats is wrong, Is it because i am using more words?  Anybody had this encountered this problem? Appreciate all suggestions and advices.    
  23. TCP connection

    I need to connect a A/B 5370 or 1756 to a PC and communicate over TCP/IP and be able to read and write input/outputs. What features does A/B provide? I would prefer to write in C/C++ but can also consider Structured Text - if it supports the standard socket type functions.
  24. 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
  25. 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- 10.113.218.34 SUBNET-255.254.0.0 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- 10.113.218.35 SUBNET-255.254.0.0 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...
