  1. FX1N

    I have a problem with PLC not seeing the input. I am using a FX3S, however, because I still am using GX Developer, it will only recognise it as a FX1N. My problem is I did a small programme for an alarm on a "Blow Down" system for filter cleaning on Silos. Tested it at home with a cyclic timer, everything working fine. Got the controller this afternoon and found I had a problem. It looks like it's not seeing the input to reset the time out timer. Worked for a while, then fell over. Using X0. The switching time I am monitoring is 20msec, which I thought would not be a problem. This is going to be a major setback for me with this project. Eight of these controllers. Any help would be great.
  2. 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. 
  3. i just got my NX1p2-1140DT controller with a R88D-KN04-ECT. i conneted every thing and directy got the 87 message on the display. i found out dat is becous wrong wiring I dont have the I/o cable incallt with omron they where saying that i don't need it and i can controll the motor controller full via ethercat. i already try to change to pdo mapping. what am i doing wrong? can someone help me? is it indeed true i dont need the i/o cable  thanks in advance for helping.

  6. serial input string

    Hi  I'm quite new to plc but very new to mitsubishi.   I have an input string eg G+002.7 which represents a weight. I wish to take in the input string then move/convert to int omitting first char,   On other plc's i have been able to use a modifier like d200[2] then the no of chars. How do i achieve this in gx works3   Any feedback gratefully recieved   Paul  
  7. Hi,I want to read transducer signal on PLC.I am using 7kg60008ab/nn transducer and it's analog (4-20mA) output is connected with analog meter.Can I connect the transducer current output (4-20mA) signal to PLC analog input in series with analog meter display???So that I can read the value on PLC simultaneously with analog meter?
  8. Output polarity selection

    Hello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2.                 I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. ·         When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) ·         When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) ·         On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3)                 Has any of you experienced something similar? Is there a better way to execute my purpose?                 I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!
  9. CP1W AD041

  10. unit of time in D8284

    Hello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!
  11. Hello all,  I have a temperature sensor with a reading range of 10F to 212 . The input card I am using is an Allen Bradley 1734 IE8C 8 Channel Analog current input. The current input values are 4-20 mA. Currently I have my raw low at 4000 and raw high at 20000. Can anyone explain how do we go about selection of this values ? I found these values in the configuration tag of the input card properties.  Thank You 
  12. Hello guys, how many (maximum) analog inputs/outputs can CPU 1215C can reach without any issue?   I try to search in google but can't find convincing answer.  Thanks for your help.

  14. I currently have a Rosemount 87 series flow meter connected to a 1756-IF8H analog input module.. We are not receiving flow from the device, and the channel is showing a diagnostic code of 009... I can not find a diagnostic code list anywhere explaining what this means, has anyone had any experience with the diagnostic codes for HART Devices?
  15. Q68ADG - Abnormal Analog Input

    Hi guys, So I found that CH2 on Q68ADG is abnormal. Whenever I short the termination, the digital value goes max to 4096. Input is set to 4-20mA with normal resolution. I tried to simulate 4mA-20mA but still same result. Does this mean the CH2 is damaged? Equipment at site is normal and give 5mA signal. Thanks!
  16. This is a 1756-IF8 rev 1.5 Analog Input module. This has happened a couple times where the Module Input Data, (not mapped), goes to the high limit and freezes (Data Monitor data is static).  Plant operators pointed out the trending wasn't accurate. There is no fault on the module, no yellow triangle on the system tree for the module.  The Module properties show no faults, and RUNNING. I have done a "Reset Module" both times, (Module Properties - Module Info tab), while monitoring the module data.  As soon as it resets, instantly the Data Monitor starts showing live data. I'm going to try and replace the module at first, but I have some concerns. Has anyone run into this before? I can't seem to find any information on the "Reset Module" animation, and what it actually does.  Any information, (or where to look), would be appreciated. I don't like to hot swap, but I believe I will need to in this case, (utility).  Will the current properties, e.g. scaling transfer to the new module? Thanks Dave Redman

  18. I have an 8 point analog input card on a rack with a SLC 5/04 CPU.  It has been in operation for 20 years or so.  There have been some power problems at site lately and ever since they fixed them I have been having issues with 3 of the 4-20mA circuits on this card showing open circuit.  I have had my meter on them when they show open circuit.  The signal reads 3.96mA, just below the 4mA minimum and boom, the machine goes down.  Is there a way to adjust this tolerance??  I don't think there is anything wrong with the 3 transmitters so the error is just a nuisance.
  19. Hey there forum guru's!!! I am trying to read through the manuals for an NX-HAD401 High Speed Analog Input Card.  It is not very clear as to where you assign your variable in order to grab a channels analog input value.  Can you point me in the right direction? I am thinking it is in the "Analog Input Values 1 to 10" and if so why is it set up as an array?  Is it because it takes the average of the samplings and uses the result as the channels input value? I am sure I will have more questions but this may clear up a few.
  20. IC200ALG264 Analog Input module

    Hello all, Thanks for the forum which has provided me with a lot of help overtime. I'm posting my first thread since I can't seem to find an answer to my issue. I'll quickly explain the situation: I'll be installing a RTD sensor to a GE Fanuc IC200ALG264 analog input module using a 4-20mA converter. Everything is fine except I can't seem to understand the polarities of the Fanuc inputs. I'll explain better: the module has an IC200CHS022 for the terminals, 15 terminals total, and the manual is reporting a "number" and a "connection" for each terminal. Now, the "number" seems to correspond to the visible pin of the terminal. But the positive and negative symbols are represented on the "connection", which I can't seem to wrap my head around what it means. Attached are abstracts from the manual and a photo of the terminals. Please tell me where to connect positive and negative outputs of the 4-20mA converter. Thank you.

  21. 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!
  22. 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.
  23. Hi all,  I am in the process of doing a project for some school work and need to do a SWOT analysis of the latest modular PLCs from Mitsubishi (R series), Siemens (S7-1500) and Allen Bradley (ControlLogix).  So I thought what better way than to ask the people on what they think are the pros and cons of each! Thanks for your responses in advance!
  24. hello everyone , I am involved in the development of an industrial  product. It has a 24 V On / OFF  output signal which will be read by a PLC digital input. It could be Allen Bradley / Siemens .  Can anyone tell me what would be the approximate values of the internal pull ups and pull downs? where can i find this? Thank you for all the help.  Regards Sha  
  25. This is a bizarre one... CompactLogix, 1769-IF8 with 1492-AIFM8-F-5 wiring system. My client has reported several instances where one of his flow rate displays is frozen at its maximum value.  Each time, I have gone to the site, found that the value in the analog input tag is at full scale, and measured more than 20mA at the input - as much as 28mA!  I measure it using a clamp-on meter and I measure it at the input module (1769-IF8) and the external, pre-wired terminal block (1492-AIFM8-F-5).  I cycle power to the PLC.  No change.  I cycle power on the transmitting device.  No change.  I disconnect and reconnect the input (signal wire at the module or the terminal block) and everything goes back to normal.  This has happened on multiple channels on multiple input modules and with two different types of transmitters. I didn't install this system, but it seems to have been done properly and it had been running fine for many years.  These problems just started happening out of the blue. Has anyone out there had any similar experience?  This is a new one for me after more than 25 years in the business.
