  1. 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 ?
  2. 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.

  4. Analog Input Addressing

    Hello Everyone, This is first time i am using Omron's CX-Programmer. PLC-  CP1L-EM40DT1-D I have 2 built in analog input of 0-10V on PLC Board. I want to know the default resolution, Data Type and Register address to detect analog Input for my further programming. Please Help me with these...
  5. 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!
  6. Hello! I am new at programing PLCs. I am using TM241CE24R PLC with TM3AI4 analog input module. I can successfully read temperature from 4-20 mA sensor. I want to communicate with my PC (SCADA) via Modbus TCP. For testing purposes I am using CAS Modbus Scanner. I can read digital inputs, coils and holding registers successfully. Problem is that I can't read analog inputs (#300001 etc.).  I have nothing defined in GVL list. Is this causing problem? I also don't have any Modbus TCP Slave device in Ethernet_1. But how can be all the other registers read successfully?  Please take a look at screenshots below. Also check Error message from CAS Modbus Scanner. Where is problem? Please help. Thanks in advance!
  7. Hi new to the forum, and first post, however, I have found an abundance of great information here, so I was hoping someone might able to help me with an issue.   PLC is BRX BX-DME1-10ED13-D I am trying to read an analog output from a sensor that is capable of essentially outputting a mA signal proportional to where a printed line, or contrasting edge is at in its field of view. It is used for web guiding applications to make sure the web is tracking straight, so you can identify if the line or edge is moving to one direction or the other, and correct the web with an articulating web guide. I have attached the diagram for the sensor, but I cannot for the life of me figure out 2 things 1) The power supply to the sensor is listed as follows Supply current - From fife control +/- 12vdc 50ma (+)12vdc  AND   - 40ma (- )12vdc how do you provide both (+) and( -) 12VDC for the supply power to a sensor- 2 power supplies with the the opposite polarities grounded on each?   2) The outputs are listed as "Sum" and "Differential" so apparently there are two outputs, i dont know if anyone has come across these terms relative to sensors before, but I am trying to sort these out. According to the OEM  Sensor Output Range   -20 mA to +20 mA for line guiding     -20 mA to +10 mA for edge Guiding   I have attached the pin out diagram as well as the sensor spec sheet, but I am curious to see if anyone might have insight as to how I would get an analog input reading from this configuration? Thank you in advance for any help!     224615.pdf SE-26B Product Sheet.pdf

  12. Counter module FM450-1

    Dear all, the following error happened with me as following  1-power cut happened  2-rack with DO wasn't working "meaning no DO on plc module or from PLC but from function was active & some DO was blinking very fast" action I took  1-after more try change address for DO module from H/W configuration with spare DO "using Rewiring Option" worked well  but I face the following error "i don't if problem was new or related to last action' error on counter module FM450-1  I/O access error and error on FC40 "System function for counter module" no change in H/W wiring in field was done  any one need more data can ask  DO & FM not on the same rack  CPU416
  13. 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?

  19. A1S68DAV parameter

    please can anyone tell me how to set A1S68DAV analog output module parameters , such as voltage output and resolution? or is the parameter can't be set at aLL (ie, fixed at -10V to 10V)?
  20. Hi. We are struggling a bit with the analog IO on the EIC202 coupler. Have tried tag sets, and gotten the digital IO to work without problems, but not the analog. Any tips here? We are using 2x NX102 with 1x ID4442, 1x OD4256,  and 2x EIC202 with 1x ID4442, 1x OD4256, 1x AD2603, 1x DA2603 on each, for a redundancy-system. Software is Sysmac Studio. EIP connection.  
  21. 1746-INT4 Used for Position

    Hello, My apologies in advance if this is in the wrong place. I am working on a press that is using a 1746-INT4 to look at the position of the ram.  The press is using an LDT as the sensor reading back to the INT4. It obviously works. The press runs everyday.  I'm wondering if there would be a reason to use this instead of just a voltage or current analog card?   Thank you in advance for the replies.
  22. VFD Analog output to LOGO!

    Hullo neighbors,  We've got a LOGO! 0BA8 configured to use I8 as an analog input, and the goal is to read the current operating speed of an ABB ACS310 VFD. (we want our PLC to be able to react to any changes in speed from the VFD) Problem is, nobody can figure out how to hook up the analog output from the VFD to the analog input on the PLC. Have tried going from AO -> I8 and have also tried adding a connection from the LOGO! input neutral back to the GND... nothing works.  Attached is the terminal diagram for both devices with our poor attempts labeled. Any insights?  
  23. hello everyone,,,, I want to running the motor in 100 rpm but how to setting electronic gear to control speed in servo motor HG-SR502,, does anyone know how?
  24. hallo everyone ...i use mitsubishi Q00UJCPU and QD77MS2.. i try to make a speed control program and the speed wants to be changed during servo operating, i use dedicated instructions ZP. PSTRT1 (axis 1) and have tryed but it was only successful to change speed with "change speed control" function once ... is it like it? cannot change "change speed control" many times when servo operations?
  25. I am new to Automation Direct software and how the programs are written. Can anyone explain how they handle the analog outputs? My processor does not support the IBox that makes life easier, so I am having to do it the old hard way. I understand most of the logic of how its done for sending data to one channel but I don't understand how the channel selecting works. Can someone give me a programming example or explain how that works? I am looking at the online manual that Automation Direct provides for you for the analog module but I am having a difficult time trying to wrap my brain around how they do their analog stuff ><
