  1. 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!
  2. 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
  3. Rslogix Array Search

    Hello,  I have 30 recipes(g_Blend_Recipes) and want to search for an item number in the recipes and compare it with what the operator enters on the HMI. The recipes itself is an array and there are 5 item numbers in each recipe. I read about the FSC instruction but did not figure a way out yet. I am attaching a picture of the recipe. Any help would be appreciated.

  7. Autotuning Kinetix 350

    Hell PLC World! I have been trying for several weeks in my spare time at work to tune an Allen Bradley Servo Motor.  Below is the list of hardware I am currently using: - CompactLogix Motion Controller (1780-L33ERM) - Kinetix 350 Driver (2097-V34PR5-LM) - MPL Series Rotary Servo Motor (MPL-B310P-MJ74AA) I have been using RSLogix5000 for testing and I plan to use it to develop a simple conveyor type program later.  I have tried a list of things which will be below, but to no avail, I cannot simply jog the motor for any period of time without triggering a position, velocity or bus voltage error.  I have tried changing the motor, driver and feedback cable to no avail.  Here is the process I have used: 1) Add the hardware to RSLogix5000 (PLC, Driver and Motor) 2) Configure the motor 3) Run the hookup test.  This works flawlessly.  The motor will slowly turn independently on the feedback test for as many revolutions as I input.  This is what makes me think I am doing something wrong in the tuning process. 4) Run autotune process with the velocity, acceleration and jerk set well below the limits of the hardware.   5) Attempt manually control motion 6) Recieve error I have tried changing the input from trapezoidal to S-Curve, changed velocity and position limits, manually tuned velocity gains in a myriad of configurations.  I have swapped legs on the 3 phase input (which made matters worse). I suppose it is possible that multiple pieces of hardware are faulty because this equipment was previously used, but I still cannot wrap my head around why the hookup test would work so flawlessly, yet I cannot just get the servo to rotate at an equivalently low speed. If anyone recognizes my mistake, I would be eternally grateful.  I am an intern studying control systems in graduate school and as popular as AB is, I would sure like to get some experience with it.  Thanks in advance!  
  8. CompactLogix E/IP to Kuka KRC 4

    Hello everyone,   I need to communicate a CompactLogix to a Kuka KRC 4 by Ethernet/IP but I do not know to generate the EDS file..... any clue please ?
  9. 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?

  15. 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)?
  16. 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.  
  17. 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.
  18. 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?  
  19. 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!
  20. 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 ><
  21. Hello - I've recently started my adventure into PLC programming and I've found this site to be very helpful. I took on a project that requires control of a cylinder - the short and skinny is that the cylinder will have to provide position feedback and stroke to various set lengths determined by position of a selector switch. So - If position 1 is selected, the cylinder will stroke 20"inches. If Position 2 is selected, cylinder will stroke to 25"inches - so on and so on.   My questions is how to best go about this process. I may be having a brain-block and not viewing this clearly, but something is not clicking for me and wanted some advice. Planned on using Allen-Bradley's Micro850 PLC (had one on the shelf, and CCW software is free so why not). Thanks
  22. I am needing some guidance on an application I'm working on. I'm trying to obtain data from a profinet slave device to an Allen Bradley compactlogix PLC. I am using a Prosoft PLX82-EIP-PNC profinet-/ethernet-ip gateway as a median to allow me to access the profinet data. In RSlogix5000, I have created an EIP Class 1 connection for the profinet controller and AB PLC (248 words of input data, 248 words of output data). The same structure is created in the profinet controller (248 words of input data, 248 words of output data). The profinet gateway and PLC are communicating properly. From my profinet slave device, I have a specification that the data is structured within a 23 byte format. Connecting to my profinet gateway, I can see this data. I have attached an image that shows the specification of the profinet data and the data values displayed inside the profinet controller. From the PLC side, I'm needing to be able to see this data and put it in meaningful values. I am using the profinet slave device's internal temperature as an example to work towards. I'm not sure the best way to be able to handle this data and structure it to a meaningful value inside the PLC. (I am using the device's internal temperature as an example to try and get into the PLC).   Thanks,

  24. Hello I have a problem with dl-ep1 ethernet modul. I connected the module to a IL-1000 sensor amplifier. There is some problem with the communication. How should I adjust ? I made some pic about the trouble. The sensor is a IL-600 laser distance sensor. I dont know yet how can I get the actual value.  Anybody knows how to set this modul ? If I think correctly after the right setting, if I check the sensor output:0 then, I can see the actual value of the IL-600 sensor. But unfortunatelly this part also not so clear for me, because I can connect about 15 sensor this ethernet modul.  Thank you so much if anybody help.
