  2. Hi All, I have a tiny Chinese controller all in one with 2 line text display. The documentation is not proper. GX Developer supports to program the devise. The devise is compatible to FX2N(C). Have any one in the forum used this type? I am not able to read its analog inputs AD0 and AD1 channels since I do not know which instruction I should use. I tries RD3A instruction but the PLC does not start. I attach a picture of the devise. Request support, Regards PLC-All-in-One-Text-Display-Domestic-Compatible-Mitsubishi-Op320-Industrial-Control-Board-10mt-Programmable-Controller.jpg_Q90.jpg_.webp
  3. FR-A740

    Hi One of my friend want use more analog output on his vfd. Its a Mitsubishi FR-A740 type. Currently the AM signal is for current, but he needs the speed and frequency too.  As we saw its only one analog output is avaiable, but you guys might know better. Can someone confims our theory.   Thank you.

  8. 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!!!
  9. 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 
  10. Analog

    I have plc mitsubishi A2USHCPU-S1 and there is already a program in it. The problem is, the analog input data doesn't want to be saved. How do i find the analog address instructions? Can anyone help?
  11. 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.
  12. 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?
  13. Hi,  I have a CP2E PLC (CP2E-N30DRD) with an Analog In/Out board CP1W-MAB221. I can't find a method to setup it correctly (the ERR LED is fixed in ON state). The "W516 (Section10) CP1L-EL_EM ANALOG OPTION Boards" manual says to "set the baud rate of the relative option port at 115200bps in Toolbus mode.", however in CX-Programmer , under "Settings" and "Serial 1" tab there is not such protocol. In w614 (cp2e software manual) and w613 (cp2e hardware manual) I haven't found any other tips. Can you help me please? Thank you.
  14. 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!
  15. Analog input melsoft (fx3u)

    Hello, I am new to the programming of logic controllers. I have a Chinese FX3U 24 inputs and outputs with analog in and outputs. I am trying to teach myself the basics of the programming but I am stuck at the analog part.    what I am looking to do is create a program so that when a 12v battery bank voltage drops and rises it can trigger other outputs. I have a voltage divider which outputs 1/5 of the input.    Thanks for your help in advance.  Ben. 
  16. I have an analog output card 1734-OE2V. As a default, there is selected fault mode as 'Go to Low Clamp'. I am using output range -10V to 10V. What is the value for Low Clamp. Is it 0V or -10V? If I want it to be 0, do I need to select 'use fault value' and set the fault value to '0'.
  17. LOGO!SoftComfort - Help with Analog Instructions

     Hello! I was trying to configure an Temperature Sensor using the Analog Threshold Trigger to parameters and output activation but, when I put this function on the program, there's just input point, on the output there's no way to link to an DO, when I select the other one's analog function's to see, they all have the same problem. How can I fix this?
  18. 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 ?
  19. 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
  20. 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.
  21. Hi guys, I'm in another project with another brand on PLC and this time I thick I hit a pretty solid wall. Long story short, I need to change a -10 +10v signal send to a DC motor drive based on a "recipe" selected with a 10 positions camswitch. I've never programmed schneider PLC, except the zélio one who are pretty simple to understand. Apparently Modicon are much more complex to program with the knowledge I have. Is there documentation available somewhere I can use to understand how to code analog output.
  22. 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.
  23. Delta PLC Analog Wiring

    Good day all, I recently working an assignment to read analog data from sensors. I connected everything just as what the manual for sensor stated. My PLC is DVP20SX2 and the sensor data i want is 4-20mA. The analog sensor has two wires, Analog Output + and Analog Output GND. I connected the + to I0+ and the GND to the VI0-, but when I work online using the ISPSoft, I can't get any data. My doubt is the wiring. Can anyone guide me on this? Is my wiring wrong? does analog works the same as digital, where we have to connect to same COM?
  24. 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.

  25. 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!
