  1. 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. 
  2. 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?  
  3. 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!
  4. 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.  
  5. 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? 
  6. 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.. I had connected them but still error.. Side hmi that im connect is 10 RDA to SDA 11 SDA to RDB 15 SDB to RDB 16 RDB to SDB 7 SG to SG  
  7. 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?  
  8. 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?   
  9. 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
  10. 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.

  13. 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  
  14. 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.
  15. 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
  16. 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?

  18. 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,
  19. How to take single bit form input WORD by Structured Text? Can i write somethink like: inVar[i]  
  20. 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.
  21. 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.
  22. Hello everybody, I am connecting my DCS digital output (115VAC) to AB PowerFlex 753 Digital Input. We are using the 20-750-2262D-2R I/O option in the powerflex which is 115VAC I/O with 2 Analog In, 2 Analog Out, 6 Digital In and 2 Relay Outputs. My question is, what is the current or power consumption of the PowerFlex DIs at 115VAC. I need to specify the right fuse size for my digital output. Thanks,
  23. I'm new to Omron, and after several days of diving into manuals trying to figure this out on my own and giving myself a headache I've come to accept that i need help. my task is the following: Control of the discrete and analog inputs/outputs in a DeviceNet system using an Omron CJ1M PLC’s and PT’s. Use at least one thermocouple, one analog input, and one analog output for the DeviceNet network. Use a pushbutton and a light for the start of the process and an indicator for the started process. I have a Drt1-Ad04 input, a Drt1-ad02 output, and a Drt1-ts04t temperature control. My devicenet is Cj1w-drm21, The Omron system itself is a cj1m-cpu13 etn21. I have node addresses for my input, outputs and temperature control, those being 35 for input, 25 or 30 for output and for temperature control 5, 15, or 20. The ip address im using for this project is 142.214.143.9I'm using Cx programmer, Designer and Integrator. On Cx programmer I've managed to create an IO table but i have no idea on how to begin the program or even get a current reading from my generator.On Designer I've made what i believe to be the layout of the pushbuttons, I just have no idea of what addresses to enter.And on integrator i'm having troubles on figuring out how to make a routing table. I've went through many manuals and either i'm missing something really basic here or I just have no idea on what I'm doing. The only advice I was given was to dive into more manuals and find my addresses for my inputs, outputs, and temperature or to find the information from an outside source be that a forum or customer service. I am able to provide more information, and screenshots of what I have done if needed. Any kind of help would be greatly appreciated!
  24. For "string display and input" objects, there a "full keyboard" option that, when selected, will cause a keyboard screen to pop-up when you press on the input object. Is it possible to change this keyboard to one with Russian characters on it?
  25. I am working on Remote IO panel and plan to use the following components: 1734-AENT 1734-OW4 - qty 2 1734-IE4C I wonder if I need to separate the bus between the relay output module and analog input module? Or anywhere else in this setup? Thanks.
