  1. PLC Not fast enough?

    Hello, I used a Schneider Electric SR3B261B PLC to create a trivia machine (as I call it).  Basically 20 buttons that let contestants ring in to trivia.  There is a display that shows the number of the person who rang in.  It works pretty well unless people press the buttons at exactly the same time.  Then it shows 2 results at the same time.  Usually resulting in a display of 18 when really it was 12 and 14 that rang in, for example. The PLC has options for: "Adjustment of the basic cycle time of the module."   and "Type of Hardware Input Filtering." Which I assume would make the PLC operate faster and avoid two inputs triggering at the same time.  If I change the setting and update the changes do not keep.  I appear unable to change it past 20 x2 ms  and slow (3ms). Is that a correct assumption that changing this would fix it? Why can I not change this?  Is it because I have so many inputs (14 or so) and Outputs (16 or so)? or because my program uses nearly all 240 lines of ladder logic allowed? What can I do to fix this?   Emerald
  2. Control Panel

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  3. Omron Hardware

    Please let me know if it is allowed to sell PLC hardware on your forum. I accumulated lots of Omron hardware  that I want to get rid off. Here is the list, I have several of each type, asking $12 each plus shipping. All in working condition.  Base Unit C200HW-BI051 Base Unit C200HW-BC101 16 Point DC Input Module C200H-ID212 16 Point Digital Output Module 24VDC C200H-OD212 Power Supply Module C200-PA204    
  4. Anyone have experience with the Peak to Peak hold function on Keyence IL-1000 amplifier?  I have an IL-030 lase head running off it and I want to utilize the peak to peak hold function.   I connected the red wire from a generic 24VDC, 1A, power supply to the IL-1000 Pink/Purple (timing input wire) and the black wire from the power supply to IL-1000 Blue (0V).   I have a 24VDC, 5A, power supply connected to IL-1000 Brown (10-30V) and IL-1000 Blue (0V) to power the IL-1000.   What I thought might work is to plug the 24VDC, 1A power supply in and out of an outlet to trigger the timing input for the P-P hold (similar to an on/off button).  But it's not doing anything.   I am not an electrical guy.  Any tips here?  Thanks,
  5. Hello everyone, I had seen a couple of threads concerning a serial module from Mitsubishi but still wasn't able to get the answers I needed, so I am no longer a lurker but a member. I have a Q06 PLC and QJ71C24N-R2 serial module, I am using a Sick IDM 260-100H scanner. The serial module has never been installed and currently the scanner is being interfaced with the GOT2000, but I am limited on what I can do there, so I bought the serial module in hopes of having more possibilities using it.  So my goal would be to scan different bar codes such as a DM and 2D line bar code and have that data input into a register, from there I will be able to write the code of logic to manipulate that data the way I want. The problem is I have a couple issues.  First when I scan the DM code, it inputs into the device register that I assigned in the auto refresh tab for that device, but not the entire code, I would assume this is just an issue with the allotted address assigned. Problem with that is I haven't been able to figure out how to extend this to reflect the entire string.  The other issue I have is when I scan the 2D line bar code I get nothing. I am not 100% sure if this is due to the scanner and it possibly programmed for only DM's but I have replaced this scanner before and I just plugged it in and it started doing what the broken one had done, so I don't think this is the issue, but I will not rule it out.  I have attached a couple screen shots of the switch setting and the auto refresh screen, but that is all that I had changed to the module parameters to get where I am at. Any information will be useful and appreciated. 
  6. HI I'm using PlC5/20 when I click on setup screen on the BTR block (to view the analog input configuration) i find the following message: No modules exist in the IOconfiguration for this R/G/M however the analog input signals is running properly....i just want enter the setup screen for configuration. I'm assuming that I need to enter I/O module in the I/O configuration? Can I do this without taking PLC to Program mode?  
  7. Hello! I am new at PLC programming. I am using TM221CE16R PLC with TM3AI8 analog input module and SoMachine Basic v1.6. I am trying to scale analog input value. I am using 4-20 mA pressure sensor. I managed my wiring so that I get raw values in SoMachine Basic. But I don't know how to scale these values to usable values. My sensor works in range 0 - 16 bar. What is best way to get values? Is it PID function block or multioperand function block using equations to get range 0 - 16? I will appreciate your help.   Thanks in advance!
  8. High-Speed Counter Input

    Hi, I working on reading impulse from the input. I am using M8000 as a contact, on the coil [C235 K9999] and it is working fine on the lad, but the problem is I need to applicate sth like that in structure ladder but I dont know how. I found function on the image below but it is for FX3U. I know that 2-phase 2-count input use OUT_C(for example EN True| CCoil CC251| CValue K0) and then DMOV(for example EN True| s CN251| d D100), so is there any method to read impulses from the input? .Thanks in advance. PS I have Mitsubishi FX3G series.  
  9. QJ71C24N INPUT PROBLEM

    I am using QJ71C24N to communicate with my devices, ASCII mode. I can send my output to the device by using non-protocol method ( G.output). However,  when I using G.input to try to receive the feedback from my device. The signal seen not stable to receive by my PLC. Sometime can get the full signal sometime can't and sometime I get some messy signal. Is there any setting I need to set to get the stable feedback from my device? Please anyone can help me to solve this problem? 
  10. error HMI in proface GP477R-EG11

    Hi everybody, can someone help me, to solve my problem with commnunication error. ??? I have plc Q03UDVCPU using module QJ71C24N and HMI proface GP477R-EG11  using RS 422..

  11. Hi I have some problem about QJ71C24N with Modbus RTU Predefined Protocol. I have setting predefined protocol for QJ71C24N and use 485 wiring to modbus slave but when I start communication it returns CRC error then I use Circuit trace to check communication that result as in attachment that there are some echo back from send command mix with response command from slave device I think with these response cause crc error because there are some echo back in response data I have setting echo back to prohibit but result are same. How can I solve this problem?  
  12. QJ71C24N-R4 G.Input command

    I need some help with G.input and g.output commands. I have a Q04UDEHCPU and my slots are as follow: slot 0 - QJ61BT11N cclink slot 1 - QJ61BT11N cclink slot 2 - QJ71C24N-R4  2-channel RS4222/RS485   I need to have 2 separate RS485 stings going to different devices. I cannot find the way of setting up the g.output command. G.Output "Un" (s1) (s2) (d) "Un" says it is the start I/O signal of the module, but I am not sure what that means. What there be a different "Un" number for each channel?   
  13. Hi,   I am using Omron CP1E NA 20DTD with built-in ANALOG inputs and output. I know how to deal with digital inputs. But I have no idea about analogue input wiring and programming. I tried connecting gefran LVDT PY2 directly to an analogue input of plc. But the indicator light did not turn on. Do I need to use any signal conditioner or converter? The output of lvdt is 0 to 25volts. I HAVE ATTACHED THE DATASHEET OF LVDT. DTS_PY2_06-2016_ENG.pdf
  14. Hi everybody. I have 1 QJ71C24n-R4 with 2 channels CH1 & CH2 and I want to use Modbus RTU for both of channels to read data from electric meter. Now I can do it well with CH2 but cannot with CH1. The reason is echo back setting, my GX work 2 only able to prohibit echo back on CH2, not able on CH1. Does anyone know about this problem? Please give me some advise. Thank you so much.

  17. Hello all, I'm using MC Protocol Format 4 to communicate with a VB6 application on a PC. I want to make some slight modifications, and I am getting a sum check error being returned by the module to my application. I believe (haha) I am calculating the sum check code correctly for Format 4 as most commands do work (reading for example). I was wondering if anyone knew of the buffer memory location on the QJ71C24N card that stores what the card is calculating for the sum check? This way I can have a troubleshooting tool to see what I am calculating wrong. I have looked through the manuals (application/basic) for the C24 already as well as the Melsec Reference Protocol manual.  I have attached the error code for reference, again, I am only looking for what the C24 calculates as the sum check code. Thanks  
  18. Hi, Iam new to schneider electric PLC drive programming and also to canOpen communication. I have an LMC058 PLC and there are three Lexium 32A drives connected via canOpen which inturn controls three servomotors. My question is how to find/ read hardware limit status of the axis in which limit is connected to a digital input pin of the drive. Even though the axis is properly working by configuring the digital input pins we are unable to get the digital input status of the drive. In the drive manual its given that the digital input status can be read from canOpen address 3008:F(hex) we dont know how to read the status during run time in the program . Can any one advise me how to read that address. I tried SDO_read function but its giving me error(canOpen network id Unknown). Thanks in advance.
  19. G.INPUT

    I'm working on a project that reads an RF - TAG via RS232. It uses the G.INPUT command. I need some help to see if I understand clearly how it works. Now it reads a maximum of 16 digits but in the future i want to pass it to 32 bits. The command line is |G.INPUT    U5    D6500    D6800    M7922| If I understood correctly I load in D6500 either 1 or 2 to tell it which channel to read from. It stores the 16 digits in words starting from D6800 and goes on till D6815 if I am correct. My questions are: - did I understand correctly how to use the command and is there anything else i need to take care of while using it? - do I need to do additional settings to it in order to read 32 digits or does it automatically read (if the RF reader is compatible with 32 digits)? Thank you, Andrei
  20. Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do?
  21. CPU 948R

    We have Redundant S5- CPU948R we have the requirement of knowing input address for FUM signals(Open & close signals).. Also how can we identify which cpu is acting as main CPU and which one is Standby. We look forward to a solution. Kindly advice us.
  22. Current Monitoring

    Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,
  23. How to take single bit form input WORD by Structured Text? Can i write somethink like: inVar[i]  
  24. Hello! I am programming with FT view studio version 8. In the program, when I make numeric display, I can not input values for this tag I am using in the display. Then I decided to make 'invisible button' for enabling the input for this tag which is shown in the numeric display. This is okey for me, only if there is other ways to do this please tell me. Now when I have created this numeric display with input enabling -'group', I have a problem, how can I use security levels for this group, so that only logging in values can be set? I have found that there is security code selection for this in the screen displays, but not for the buttons.
  25. Rotary input device

    I am looking for some sort of rotary input device which could be used for fine adjustment. Ideally it would have to two output pins, if turned clockwise it would send pulses on one of the pins and when turned counterclockwise it would sent pulses on the other pin. These could be connected to two inputs on PLC and a value in a given variable could be incremented and decremented depending on the direction of rotation. Almost like using potentiometer with analog signal. I guess if I can not find anything I could use incremental encoder and look at the phase of the output to decide which way it is being turned but hopefully simpler and maybe more cost effective solution is out there? Thanks.
