  1. 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. 
  2. Analog output fault

    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'.
  3. 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?
  4. 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 ?
  5. 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
  6. Wireless programming fx3g

    Hello, Can I get a laptop usb bluetooth receiver and a usb-> mini usb adapter and plug the bluetooth receiver into the programming port of a fx3g PLC for wireless melsec software connections? Seems like it would be a nifty little addition to any panel.  https://www.amazon.com/Bluetooth-Adapter-Wireless-Compatible-Computers/dp/B071WKP37Q/ref=asc_df_B071WKP37Q/?tag=hyprod-20&linkCode=df0&hvadid=309751315916&hvpos=&hvnetw=g&hvrand=14775611605752866986&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-761431569272&psc=1&tag=&ref=&adgrpid=67183599252&hvpone=&hvptwo=&hvadid=309751315916&hvpos=&hvnetw=g&hvrand=14775611605752866986&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-761431569272 https://www.amazon.com/Ksmile%C2%AE-Female-Adapter-SamSung-tablets/dp/B01C6032G0/ref=asc_df_B01C6032G0/?tag=hyprod-20&linkCode=df0&hvadid=309833041189&hvpos=&hvnetw=g&hvrand=3896490646336226374&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9058221&hvtargid=pla-567647287320&psc=1
  7. Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.
  8. 1747-NI8 Open Circuit

    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.
  9. 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.
  10. 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.
  11. 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?
  12. 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.

  13. Reading FX3G PLC

    how to read fx3g plc 16 bit keyword ?
  14. 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!
  15. Hello, I need to connect multiple barcode readers (SICK CLP510) to a PLC (FX3GE-40M) for a university project. I need a minimum of 3 bar code readers, but only have one operational, connected via an additional modul for the use of rs-232. The only other port I can use is a miniDin 8, which is a build-in rs-422 port. Because this is a university project, it needs to be as cost efficient as posible. All the readers are CLP510 (pin-out attached bellow) Thanks Becky Pin_out___wire_colour___signal_comparison_CLP100_CLP510_CLV60x.pdf

  18. PID Loop Review

    Hi all, I am trying to set up a PID loop for a project I'm working on, and I was hoping someone could take a look at it for me. Most of what is written comes from the Q, L programming manual, but I've changed a few things so that the program can write changes to the SV as needed. The processor is a Q03UDE and the Analog Module is a Q64AD2DA, using only channels 1 and 5. Thanks for looking! PID Project.gxw

  22. Analog range

    CP1L-L14DRD CP1W-AD041 I have my configuration words set to #80BB for both output words with the intention of having 0-10 input. With my input voltage at 5.25 I get 6300 the maximum range. I entered the bit wise in my calculator 1000000011011101 and it converts to 80DD. Tried both those options with the same result. Can anyone shed some light on what the problem is?
  23. 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.
