  1. Hello.  This is my first post and I hope someone has a solution. I have a program calculating Gal/sec adding to a running total and have up to the end.  Using REAL I can accumulate up to 16,777,216 (2^24) and using DINT up to 2,147,483,648 (2^31), but I need to have my registers continue past these limits.  I've read through many topics here and have tried the Rockwell Knowledge Base but can't seem to find a solution that truly works.  I have gone so far as to transfer the DINT to a string, cut the string into pieces and reassemble them in an Odometer type concatenation. If anyone has a suggestion, I would appreciate it.  I know I'm not the only one with this problem. PS & BTW - I'm using Studio 5000 v24 with a 1769 L33ER

  2. Particulate Measurement In CX Programmer?

    PenneyInstruments posted a topic in CX-Programmer

    I am currently in the process of an efficiency project for a company looking to measure at what point their process starts to create particulate (in this case, smoke) so we can accurately defer the smoke into a combustion chamber to be burnt off. My question is, is it possible to use the Dywer SERIES PMT2 Particulate Transmitter for our measurements using a CJ2M-CPU33 Omron Controller and CX Programmer. http://www.dwyer-inst.com/PDF_files/PDS/DS_PMT2Rev.1.pdf If we can use this, I am wondering which cards I would have to get for communication to this transmitter? CUrrently I have analog in and out, (DA041 and AD081-V1), and digital in and out, (ID211 and OC201). Any information on getting this sensor set up is appreciated. I am not familiar with this type of process control. *****FYI If this is not the correct topic to post this, please move it to the correct one.*****
  3. Thanks for your time.  We have purchased from auction a Getinge Autoclave (sterilizer) with Allen-Bradley controls (CompactLogix L32E).  The machine has a PanelView Plus 1000 installed.  A CD came with the machine w/ the following files.. HMI Project - (.apa file) Runtime (.mer file) Their is also a compact flash card installed in the CompactLogix L32E.  On the Panel View, their is an external Compact Flash slot, but no card, and on the inside of the panel view (if i remove the back cover) their is a compact flash card slot with a card installed.  I haven't checked what is on either of those cards yet.. We cannot get the program to load on the panel view. When the machine is powered on, the panel view goes through a quick dos setup screen and then the screen turns blue and we are stuck with an hour glass icon.  The icon will move depending upon where you touch on the screen.  I can boot the panel view in safe mode (by hitting the default button, then reset) at which point I get a message stating that the machines files may be corrupted and leaves me the options to Download new Firmware, or Continue.  Hitting Continue nothing happens, and choosing Download gives me Ethernet, or Serial options.  The Panel View is connected to the PLC via ethernet so I choose this option and it  gets stuck at this point. We do not want to make any changes to the program, but just to get it to run on the machine.  We do not have ANY of the software. Any advise is greatly appreciated. Craig
  4. hello everyone, I'm trying to connect PC with Micro830 with RS232 cable for transfer serial data. However, the PLC can not receive the character from PC. I used ARD function block to read the characters from PC.  there is no error and the output of ARD function block is 0 when I debug ladder programme. the serial communication state LED illuminated once I send a character from PC to PLC. the channel of input is 2 which is the embedded serial port. I use an adapter from USB to RS232. Email: jeremietang531@gmail.com      
  5. Hi, Could someone explain or direct me to better understand the RS Logix 5 comparison tool? I'm comparing multiple PLC codes and having a little bit of trouble understanding what the concept of "deletion", "insertion" etc are portraying. Since, some rungs are labelled 'deleted' and 'inserted' in the comparison, however,  the rung labelled deleted seems to exist in the actual code?
  6. Hello admin, Im new to PLC domain , i have one OMRON CP1E N30 with in built RS 232 port and ladder program to run in Homing and forward and reverse motion. I want to control the PLC from a computer using RS 232 communication. From what little i read from manual supplied for programming ,i came to know that there are two type of commands C mode as well as Fins commands. My doubt is whether these commands can read/write CIO memory addresses that are used to set and reset the motor enable/disable in ladder program through CX programmer software? for example: in my ladder program CIO memory address 30.00 is the motor enable/disable address so if i want to control externally from a PC to enable/disable the motor ,which commands should i use and is there a format to send these commands as well as the value. I am planning to build a GUI in Labview to cotrol the PLC via Serial RS 232 . How can i do it ? Thanks in advance.
  7. Good day  I require some assistance with the configuration setup (GX Works 3) for FX5u PLC inter-communication (PLC to PLC), over Ethernet (using the built-in Ethernet port). The purpose of the inter-connection is data exchange. (Values stored within the PLC storage registers such as words and bits).  Does anyone perhaps support files on this such as a procedure or example? Thanks
  8. Hello,    I have a Cognex insight 5100 camera connected to Allen Bradley L62 processor. The is working fine since the last year but sometimes the I/O module faults out with error code 16#0022. I looked online it look it needed a Ethernet cable change ( I did that but no results).  Then I looked at the firmware in the I/O module and firmware in the camera and I found a difference. The firmware in the camera is 4.06 and the firmware of I/O module in the PLC is 4.005. Can anyone help me resolve the communication issue ? I want to know how to downgrade the camera firmware or change the revision in the PLC ( which I cannot )    Thanks in Advance

  10. Good afternoon fellow members,I once again ask for your help to know if any of you have struggled with similar issues. For the past year and a half, Every 1-2 months we seem to be losing communication with one of our PLC's/racks. We have in the rack a 1756-EN2T card (revision 3.006) that will flash as if it is communicating and status OK (green LED), yet we will be unable to ping it and our operator interfaces go into error. We could also not open the web browser page of the EN2T card, nor connect to the PLC/rack through RSLogix5000. As this happened over the weekend, the local electrician was called and he tried cycling power to the rack and there was no change after it came back on (not sure how long he left power off to the rack though). The problem seemed to be fixed after we told him to pull the EN2T card out of its slot and then re-insert it.We verified the CIP cinnections for this card and it is around 98 to 101 CIP connections out of a max of 248, so not too high. the card's CPU usage is 24-29%, so no indication of problems there. EN2T Card is set to auto-negociate, just like all the other cards we use at all of our plants. Has anyone ever experienced a similar problem?Thank you in advance for all your help and knowledge-sharing!
  11. Hi everyone! I am currently using both Motion controller Q172DSCPU and Simple motion controller QD77MS for my application. I spent time for Advance synchronous control with Motion controller QD172DSCPU. However, I wonder that is there any solution to combine synchronous control and interpolation control? For example, I need controlling 4 axes consisting of 3 axes for helical interpolation and 1 axis for linear position control. The problem is that all 4 axes start and complete position at the same time. Does anybody have experience in this? please share your ideas. Thanks in advanced.  

  12. Beckhoff Control panel testing?

    acuralegendz posted a topic in Other PLCs

    I am a technician at a large repair facility and we often have Beckhoff control panel displays come in for repair. I'm having trouble using Twincat to set up the buttons on a CPxx to test the buttons and assignable leds. We have a PC running windows XP with the twincat software, a CP9035 pci card to connect the CP to the pc, i can see the PC's display on the CP and also recognize the CP in twincat, just unsure how to map testable functions to the keys on the CP. Hope this all makes sense. Hopefully there is a Twincat guru out there that knows how to do this. Thank you!!

  13. Ground Loop

    AKesh posted a topic in Control Panel Building

    Hello everyone, I have a quick question regarding Din rails, chassis ground and ground loops. Here is where I am getting confused. I connect my back panel to earth ground which, connects my control panel chassis to earth ground. I screw din rails on my back panel. Question #1: logically, my din rails are now connected to earth ground through the screws connecting to din rails to the back panel. Am I wrong here? As I have seen in many control panels, I connect a ground terminal block to my din rail and connect it to earth ground (the terminal block couples with the din rail through metal clamps). I now use that ground terminal block as a single point source to ground all my other components in the control panel (I connect my ground terminal block to earth ground using a wire).. *** the ten thousand dollar question is Didnt I just create a ground loop between my ground terminal block mounted on the din rail and my back panel chassis ground. For one reason or another the two different location might be at slightly different potentials causing current to flow. Where is my logic off here???? Thank you
  14. Hi, I'm a long time lurker and would like to start by saying thanks for all the help over the years, much appreciated!  This is my first post, please be gentle. I'm working through a large project with an L83 (V28) including 75 EIP nodes & 5 servos.  We have a need for quick real-time response of 2 cameras during a quick servo move (taking several pictures).  I've broken my program up into a few event driven tasks (allowing me to chose the execution time interval (5 to 8 ms for more important tasks and 20 ms for less important tasks, etc.)), along with these I have 2 periodic tasks: 1 for my HMIs & faults running every 30ms and 1 for this quick real-time response camera situation running at .5ms which contains my camera and servo logic.  Everything is running well and seems responsive and repeatable enough, but I am now adding the second half of the logic which will essentially double everything (2 up system).  This has made me consider the best structure approach: Is it better to have a few larger routines within a few larger tasks or better to have more smaller tasks containing an abundance of smaller routines or some other different mix? Thanks, JD43    

  15. delta hmi communication speed

    Unobtainium posted a topic in HMI & SCADA

    Hello, i have DOP-07s411 delta hmi and i want to interface it with microcontroller using modbus (RTU) protocol over RS485( 8 bit data,1 stop bit, parity none,19200 baud rate). i have good speed of communication if i do not use macros. But as i place background macro(background macro is only 4 lines ) it slow down and  updates the display at every 3 seconds. i cant able to figure out what is the problem. I want to update display of  HMI very fast.Please help me to troubleshoot the problem.
  16. Hi,  I'm trying to test the serial communications with my Micro820. I acquired a 2080-SERIALISOL so I could have "someone" to talk to. I want to use RS485, so I figured that I'd have to connect: Modbus pin 1 (D+) to serialisol pin A1 (+485) Modbus pin 2 (D-) to serialisol pin B4 (-485) Modbus pin 3 (GND) to serialisol pin A2 (GND) Now when it comes to CCW, the thing gets a little harder. I know I need to use the MSG_MODBUS block (in fact I need 2, one for the modbus and another one for the serialisol), and I guess I specify the interface I'm using on the TargetCfg field (data type MODBUSTARPARA). But how do I figure out that the Addr (UDINT) and Node (USINT) values are for my Modbus and Serialisol? Or am I doing it wrong? Does anybody know of any place where I can get some more guidance or even a funcional ladder program? Thank you in advance

  17. Mitsubishi communication error

    Dear all,   I have Mitsubishi FX1S Series PLC while i am downloading program , i am not able to do it and i am getting error. please find attached image and please help me to solve it.
  18. Hello guys, Newbie on this site. I am looking for a run time free Allen Bradley .NET driver. Basically a library (.dll) that implements communication protocols to Allen Bradley PLC's ( CIP, Ethernet/IP, etc.). Can someone point me in the right direction please ?.
  19. Hello,  I am a newbie to the Omron world. We have a new machine come in made on Omron PLC, we are trying to get it connected to our OPC server so that the server can read and write tags via ther Ethernet/IP protocol. We have given out ethernet card 10.14.9.187 IP and the NJ501-1300 controller is on 192.168.250.1. But still our OPC server cannot see the tags/variables. I dunno if we have to add the ethernet communication card to the network configurator and add the tag sets ?  We are also getting a tag resolution error on sysmac studio while being online.    Thanks Pratik 
  20. Hello,   I am looking for examples on using serial communication with a WMS inside Studio 5000.  Sample programs would be ideal. And I would like to get some information on what blocks need to be used. e.g. Send, and Receive   Thanks!

  21. Master/Slave Communication

    MZohaib92 posted a topic in Other PLCs

    Hello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.
  22. hI.. I've asked for this in the past and, so far, haven't been very lucky.  Most of the projects I run into have 4 or 5 axis, lots of analog and sensor input.. or don't have the HMI part of the "Machine" I have a nice NJ 101-1000 with the NA 7 inch HMI.. along with a R88BD-KNA5L-ECT servo and a 50W  G5 motor.. type  R88M-K05030H-S2.  All On a nice rack with power supplies and some EtherCAT I/O  (It all functions .. even "MC Test Run" gets the motor to jog ..    But.. no way to "home" it.... The motor is in "rotary mode"   but... it's NOT got an Absolute encoder.. it's a incremental... sniff!     I just want it to stop on zero ..Or anywhere, and call it zero ... and make moves plus an' minus in degrees, that's all....  I assume I have to send it some signal (push button) while it's spinning that tells it it's in "Proximity" to home and it then it does something which makes it end up on zero.    I've homed a lot of linear motors (LinMot) an' they are very easy to work with.    But, Omron has 10 different homing modes .. and they aren't very well explained.  Well, they aren't explained at all in that 502 page user manual... you have to already know how to do it, in order to understand the explanation... Example:  Take the "Home Proximity Input Signal"  .. I can imagine what it might do, to help control a move to home.  I can even imagine what's making the signal .. and that somewhere there is a place where the homing parameters are set... like the "axis setting table"  .. but, it's not a Global Variable, or a Data Type .. I could imagine it gets into the system from the CN1 I/O connector? or some I/O somewhere? But.. I grow weary of imagining how this system actually works..  Building a simple working project, from a tutorial, or even downloading a simple working project (.smc2 file) and making the minor adjustments to fit my equipment ... would make all the difference in the world.   I've searched Omron's Libraries of .smc2 files.  Haven't found any yet that aren't on the level of "Top Gun" (a seriously complicated project for a 1-week training class) ... Oh there are several.. related to IAG object files .. but those Library files are not "working projects" intended to serve as a Tutorial.. they are limited projects, ready to be configured with IAG Object files, and "your" programming ... So that you can write the programs you need "faster"... which is nice... but, no help here. Somewhere out there.. is a nice simple .smc2 project file where you get to control a simple motor from the HMI  ..Preferably using an NJ CPU and a NA HMI .. home the motor.. jog the motor and input a few "go-to" positions... sigh!..   Like you would do in a One or Two Day class...   This kind of thing should be already be available in the Sysmac Library ... Thanks much for listening..  sorry about the rant.  

  23. FX3U For GXworks2 and WinCC Flex

    markyspicer posted a topic in Mitsubishi

    Hi, Is there any way in order to monitor both PLC(GXworks2) and HMI(WinCCFlex) using only 1 port from the PLC(FX3U)? I have tried it but I'm not able to communicate the other application(one at a time only).   Thanks!

  24. S7-300

    BradDavis posted a topic in Siemens

    Has anyone ever use a Allen Bradley 9300-ENA card with a Siemens S7-300?
  25. Hello, I am currently installing a PLC control panel and due to space constraints, we will need to install the Panelview 600 HMI separate from the Micrologix. We purchased a 50ft Allen Bradley communication cable, but 50ft will not be long enough. We have about 70 to 75ft of conduit between the panel and the HMI. I would like to know what options we have for this connection. I read that for serial connection, we shouldn't go past 50ft. I understand the Micrologix 1100 has an ethernet connection and the Panelview does as well, but I'm not sure what changes would be needed in order to communicate through the ethernet port, instead of the RS-232 port. Any suggestions will be greatly appreciated.   Thanks, JCG
