  1. Hello,  Sorry I'm newbie with omron plc programming. I'm wondering how can i simulate plc program on sysmac studio with Hmi on Nb designer without hardware. because I want testing my program and my plc and hmi connection before buying hardware. Thanks in advance !
  2. How do you test PLC logic?

    We have been working with PLCs for long time. We used to develop PLC logic, partly test it on an emulator and test the rest on the partly energised equipment. From time to time working with computer software development (C# and JavaScript) I was always looking for something similar to unit testing in the PLC world. As I couldn't find anything at that time I've started developing own automated testing tool. Now we use this tool, which basically simulates PLC inputs in defined actions and checks expected behaviour of internal tags or/and PLC outputs. If it behaved the way we expected, it's PASS, otherwise it's FAIL. We break complex logic into small parts and create unit tests for it. By creating more of these unit tests we can test PLC logic of any complexity. The software called PLC Logic Prover and it's free at Recently, I've been told that there is no point to develop anything new if there are already great tools on the market. Honestly, I didn't do proper research earlier, so I'm here asking the experts. What do you use to test PLC logic? What automated testing tools do you use? Is it using IO simulation or it can test logic by other means? Your replies are appreciated. Thanks, Alex
  3. AVE instruction Error

    A little background information here, I am trying to create a moving average so I accomplished it with the code (imaged attached) The problem i am having is the AVE instruction error bit goes true. it leaved me with a result of 1.#QAN  I did some googling and it said this is typically done when dividing by zero?? so i added a NEQ to 0 prior to loading the array. then it happened again. so i put the error bit in front of the FFL so it will stop loading the array when i get the error bit so i can see what values are in the array when it errors out. Has anyone else had this issue and what could you do to resolve it? I haven't had any luck find something that points me in the right direction. Thanks in advance for your help.

  5. Hi, Could anyone help me out on how to extract the digits present in a string in sysmac studio... Thanks in advance !!!
  6. Hi, I've been having a problem with my Schneider setup, and I can't seem to figure out the problem. I'm using Machine Expert Logic Builder and Vijeo 6.2, and I can't seem to download to my PLC. I can download to my HMI just fine, but my HMI comes back with the message as mentioned in the title. Also when I perform a full download, machine expert comes up with the message "Could not connect to the device for item "xx", selected target system "PLC name" is different from the connected device "HMI name". The weirdest thing is that machine expert shows my PLC just fine, but doesn't show my HMI. I have no idea what to do, as I feel like I've tried everything. The IP range is fine, subnet is fine. The driver in IO manager in Vijeo has the PLC nodename in it, so that shouldn't be the problem either. Does anyone know what to do in a situation like this? Thank you in advance!
  7. Please could you assist with the software required to download data tables from 4 off DIRIS A10 Multifunction Meters into TM221CE40R Logic Controller via TMC2SL1 Comms Cartridge using Modbus Protocol over RS485. I have downloaded the Modbus tables from Socomec but not sure how to get these into the PLC. I would really appreciate your help in achieving this. I am using EcoStruxure Machine Expert - Basic to program the PLC & DAQ Factory Developer Release for my Touchscreen. Link to Socomec Modbus tables:
  8. Control Panel

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  9. Q03UDVCPU

    I am new with PLC's and I am learning how to work with GX Works 2. I have two questions, 1st Question: Using a Q series PLC (Q03UDVCPU) Is it possible to convert the language of a project from ladder logic to structured text? 2nd Question: If I read a project from a PLC why is it always ladder logic? Is there any way to read out structured text?
  10. Hi I'm looking for Ladder Logic code that I could use for a plastic injection molding machine.  I am willing to purchase and/or modify existing code to meet our specifications.  We have lost the Ladder Logic out of the TI/Siemens Controller on our Newbury 100 Plastic Machine so we're looking at replacing both the PLC and the HMI interface with an Automation Direct Controller.  We have the HMI Basic Code for the Newbury but not the ladder.  I've pasted the manual below for our machine.  Any assistance would be much appreicated.  The manual was too large for me to post but I've posted a document with information about how we intend to upgrade which has a little information about the machine also.

  13. Please help find a controller. We require a controller for 8 nema 23 stepper motors. Must have pulse direction and at least 8 axis or more (16 would be nice). Must have kinematics for linear and circular motion. Must be able to use gcode such as G01 X10 Y10 Z10 A10 B10 C10 U10 V10. Must have axis parameters for all 8 axis eg velocity, rotations, etc. We also need the drivers. Must be reasonably priced under $1000 or so. We found Dynomotion KFLOP which can do 6 axis and we kind of made it work for 8 axis. It is super cheap at around $250 plus KStep drivers so under $1000 total with free software, unfortunately, it can not do kinematics for 8 axis.

  18. Hello! I have a project where I need to use Allen Bradley PLC, it might be one of CompactLogic series. In scope of the project I need to transfer few real values to DirectLogic PLC that installed on customer side. DirectLogic PLC has installed ethernet card that support Modbus TCP, TCP/IP and UDP/IP protocols as it says on automationdirect website. I start looking for Allen Bradley PLC that support Modbus TCP or TCP/UDP protocol and did find clear information. Could you help me to find out a way how I can pass the data to directlogic PLC from CompactLogic?   Thank you in advance!   Regards, Scotty
  19. Hello everyone, Working in Automation for the first time as a Co-op student so i'm fairly new to PLC's and the Automation field in general. I've recently been tasked with converting a RSlogix 5 program from an old PLC 5 project into a Studio5000 project. I referenced the manual (I'll attach link below), and had no issues using the RSlogix Project Migrator tool that I downloaded off the Rockwell website. My problem is that once I convert the program, my I/O tags that were originally sequenced in octets(0-7, 10-17, 20-27, ...) from the RSlogix 5 program, are switched into a sequential scheme in Studio5000 that just increments them in order (1, 2, 3, 4, ...). I hope this make sense, but basically the first seven tags match between the projects, but then I:010 in rslogix 5 is equivalent to I[8] in 5000, I:011 is I[9], and so on and so forth. Has anyone had this issue before and found a way to have Studio5000 keep the original octet scheme? I don't see this normally being an issue, but the customer has specifically asked that the I/O tag names be kept the same as the original program. Thanks for any help. - Ben   Converting PLC-5 reference manual link:

  21. 1756-L55/A Controller

    Respected Friends, Good day. I face a serious issue please help me to fix the problem.  We have a 1756-L55/A controller with 1756/M13 A memory card. after 2 or 3 months the program washout and the LED status on the controller are following 1. RUN --- SOLID GREEN 2. I/O--- OFF 3. RS232 --- SOILD RED 4. OK --- SOLID RED 5. BAT-- OFF 6. FORCE-- OFF  At that time CONTROL NET MODULES OK Light for Chanel A and Chanel B are also blinking and communication not established via control net and serial port AB-DF1. I switched off the power supply and after 10 second again power up the controller then OK LED becomes solid green.  i download the program and its run fine. But the problem is still there. In the controller properties the major fault shows  TYPE 01 [ POWER UP FAULT] CODE 60 [NON RECOVERABLE FAULT] what are the possible reason for wash out the program from the memory?  At that time version 16.03 firmware installed and the rslogix program convert from version 10 to version 16.03.  Is 1756 L555/A with 1756/M13 A support the version 10 firmware? i ask because the original program is in version 10 if its supported then i update the firm ware and download the original program.   Hope you will help me in this issue. Regards
  22. Hi..  someone please help me.. i'm working in omron CS1H-H CPU67 PLC.

  23. I need to run 4 exactly same devices with 4 different controllers. The logic for them would be exactly the same but the IPs and controller names would be different. Is there a way to do it using 1 project file? Basically whenever download is done the logic would be downloaded but the controller name/IP would be left unchanged. They will be connected to the same network so the IPs must be different. I am using 1769-L32E for these and all racks are set up exactly the same. Any ideas?
  24. Hello i'm new in all things about plc, i do a project for school and i use a festo fc 34 plc.

Have a nice day.
  25. All, I am using Keyence CV-X422A vision controller for my application. It is interfaced with Siemens S7-1500 PLC on PROFINET. I am able to communicate with Vision controller through PLC logic command and status IOs. There is some communication issue in updating the o/p values from Camera Controller. I have tried with & w/o Handshake Mode with these settings. The camera display shows the reject but camera never turns ON the NG Status o/p. I tried different things told by Keyence Tech support but none of them worked.  He told me to have you enable the “Result ACK Flag” in the bit allocation area and send  a signal to it. Then trigger it again with a no good part and see if that fixes the issue. I tried setting the “Result ACK Flag” to 1 after I get the “Command Complete Flag” for the trigger signal that I sent. Sometimes this works but still it is not reliable. Do I need to send only a pulse to “Result ACK Flag”? Anyone here has ever faced similar issue?  Thanks for your help. AP
