  1. Problem: I am getting a control sync fault on 2 recently installed kinetix 5500 but only when my programing PC is connected to the machine network.  Install and setup all went great over a 5 day period.  Then all of a sudden I started to get this fault. Sometimes 100 times in an hour.  As soon as I go offline, and unplug my PC the problem goes away.  I have also tried another PC connected to the Machine network and still get the same result.  Sometimes machine can run for hours with my PC connected with no problem.  I do not have to be online with controller for fault to occur. Setup: I have the 2 K5500's ethernet ports daisy chained together, and then connected via shielded CAT 6 cable directly to port 2 of the Compact Logix Controller Coarse Update is set to 3.5ms and utilization's are at 33% and below.(I have tried the default 2ms with same results) Ethernet modules are configured with FW rev 7.013. Machine network is isolated.(not connected to plant network or internet) Equipment: Compact logix L33ERM Running version 30.01. There are a total of four servos in this system all running over ethernet.  2 Kinetix 350's(not affected), and 2 kinetix 5500's. I have tried: separate ethernet cables for each drive ran through a switch different ethernet cables resetting coarse update speed connecting a different PC for programming   I am just not sure where else to go with this.  Thanks in advance for any help.  
  2. We are getting a processor watchdog fault on a kinetix 5500 but I cant seem to find any information on the cause of this particular issue.  Has anyone ever seen this before? Thanks guys
  3. Hi there! I've been looking for some fault codes table for the 1734-AENTR adapters, since I'd like to show a message in HMI with some information when there is a faulty adapter, but I haven't found anything on the internet. So my question is, is there any type of table like this for these adapters? Right now I have a PLC with some AENTR adapters in the program for testing, and since there is actually no adapter connected to it, I can see a 16#2024 error in the module properties, but can't seem to find that info in the module variables.   Do you guys have any clue on how to find this information in order to show it?   Thanks in advance!
  4. Hello Experts Fault LED is blinking in Red in Allen Bradley Micro Logix 1400 PLC Can someone please advice on how to fix this & probable reasons ? Can trial version of communicating software be downloaded?

  5. 1769-IT6

    Otto Automation posted a topic in Allen Bradley / Rockwell Automation

    Hi all. I have a 1769-IT6 thermocouple/mv input module. It is connected to a micrologix 1500 unit. The green okay light illuminates on power up, but after you download the program and put it in run mode the processor faults. Terminal block with the cjc's are on the unit. The error message just says the I/O module has encountered an error. The hex code under status bit 6 is 179h. This error code is not in the manual. Has anyone else encountered this? Oh and I only have channel 0 enabled for type k thermocouple. Has anyone else had this issue, or know if it is a configuration issue. Any help would be appreciated. Thank you. 

  6. CP1L-EM

    Robafe posted a topic in CX-Programmer

    Sorry its long !! I am recieving text from a GSM modem for text msg Send and receive (SMS) works ok but would be better if I could make use of the start code and end code. This way I could cut down on all the crap that is received when a text arrives. I get this  CMTI: "SM",0 I have it stored into D80 and I have that trigger a TXD that sends AT+CMGRD=0 and that tells the GSM to send the msg (The 0 is the current msg in memory) ------ The problem is that there is Carriage  Return and Line Feeds in the received msg ----      AS below ((AT+CMGRD=0 +CMGRD: "REC UNREAD","+19028991212","","22/10/20,16:57:54-16"  Hello this is the msg  OK)) When the PLC sees the carriage return it stops receiving data. And I have no start code or end code setup. (I am using characters received) The way around this is to set a high  character count in the RXD (More than the actual msg (More than the msg length)   The main issue with that is I get garbage in as the msg gets bigger. Its unreliable. I clear the port after each receive and that helps but still get the odd garbage. (Never get garbage when connected to a terminal prg). Any Ideas???? ps Even the Start Code is unreliable as it will start receiving a few characters late. Rob  
  7. Hi all,I'm completely new to ASCII and trying to figure out where I'm going wrong here.Application: I need to send 2d barcode data to a KGK Jet model CCS3000L Inkjet printer. Only protocol possibility is ASCII. PLC I have is a Micro850, and the only port option for ASCII is the serial port. I modified one end of a 2707-NC11 cable to connect PLC TxD to printer RxD, PLC RxD to Printer TxD, and PLC SG to Printer SG. I jumpered CTS and RTS at the printer connector, and the 2707 cable I'm using doesn't have wires on the Micro850 CTS or RTS pins.Printer company verified that I can just jumper RTS and CTS on their side and not connect their DTR and DSR pins (since I'm not using hardware handshaking). I don't really need any flow control for the application ( I don't think...again, ASCII noob here).Do the CTS and RTS on the PLC side need to be jumpered? Does the DCD pin need to be jumpered or connected to something if I'm not using handshaking?I downloaded the Micro800 ASCII read and write functions and function blocks from Rockwell library, and they seem to be working, except that I keep getting ABL error id "7". This error states, "Cannot complete ASCII send or receive because channel configuration has been shut down using the channel configuration dialog box." I have the serial port enabled and configured to ASCII, no handshaking, baud 9600 same as printer, no parity check, 1 stop bit, character length of 8.Any help in pointing out what I'm doing wrong or things to try would be greatly appreciated!   ASCII_TEST.ccwsln
  8. Trying to log into NA HMI, NA5-7U001B  Direct, using USB or Ethernet.  All attempts failed .. tho, it was easy to log into the NJ Controller, direct, with USB or Ethernet using the same PC. Then a window popped up.. saying the firmware needed updating in the HMI, and suggested launching the "update" from the same window... Then, after a few minutes.  a "update failed" was displayed on the window.. and the HMI screen changed to this: ..and the green LED went RED ... aaaaagh!   HMI no longer works... any idea why this happened, or the failure to log in happened.. or, what it will take to fix it? Please tell me it was something Omron did .... Thanks Much, Regards, ,Michael PS:  additional info..  I was using Sysmac Studio Version 1.1 .. because I could log in to the CPU (USB and Ethernet) and not the HMI.. I changed to another PC with Sysmac Studio Version 1.17 .. Now I was only able to log into the CPU with Ethernet.. USB login failed. .. and, so did any attempt to log in to the HMI (USB or Ethernet) It looks like if you use a new version of Sysmac.. better not have a device with  "old firmware" ..  I think it was the V1.17 that presented the window suggesting the Firmware Update ...  sigh!

  12. This may be more of a Zebra question than a PLC question but I will post it here. I am using Zebra's Network Connect to enable communication between a CompactLogix L13ER and a ZT410. My issue is that the QR Code omits the 5 elements of the array in Field 1 of the CompactLogix. I expect the first two elements in the array to be ignored per the manual but the first 5 has me puzzled. All the characters in the text shows up fine. I have attached what I am seeing. If you have a QR Code reader, you can scan the QR Code.

  13. Unconverted Ladder Code?

    berkotropia posted a topic in Mitsubishi

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks
  14. 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'.

  15. 1734-IB8S "Blip"

    KathyPatrick posted a topic in Allen Bradley / Rockwell Automation

    Question from a PLC newbie....  We had a "blip" during a thunderstorm where we saw multiple signals on a 1734-IB8S point I/O transition from true to false for ~ 4 seconds (based on our DCS history from a serial connection).  There are several other modules on the backplane, and we only saw state change on this one card.  The 24VDC power is sourced from T-0 for points 0-3, and T-2 for points 4-7, so we don't suspect a short.  It's been suggested that we either had an I/O card "blip", or temporary loss of power to our field contacts (limit switches) caused by dust/vibration of the removeable terminal block.  Our controller is a 1756-L73S GuardLogix 5570.  My question is should I expect to see an I/O fault in the Minor Fault history (we did not)?  Would an I/O fault necessarily show up in this history, or does it need to be configured somewhere? Our points on this card are set up as single points with test pulse from T-0 and T-2.  We are reading status of limit switches in the field. Thank you in advance for any response. Kathy  
  16. I had axis fault, which stopped the PF527. Only way to go on was to switch power off and on again. Checking the faults&alarms, I find out that the reason was Bus Undervoltage user limit. This made 'Immediate Stop' for the PF527. Looking at the parameters, I can not find any parameter for this. In the manual it is said 'DC Bus voltage level is below user defined limit given by Bus Undervoltage User Limit, or device defined limit if the user limit attribute is not supported.' What does it mean?  Is there parameter for this limit? Checking the AXIS_CIP_DRIVE tag parameters, DCBusVoltage is not showing anything, why is that? => Reason found, not marked in 'Axis properties' Cyclic Parameters page
  17. Hi,     I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol.  I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC.  I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command).   How do I write or read the timer SV Values?  Example command and response : @00R#TIMH001028*  (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS) Response: @00IC4A* Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this? Please help.  
  18. Hi, I have problem with 5069-obv8s, trying to use it for a first time just to power relays and contactors. All outputs are in internal fault, even if their are not conected. The card is set to use single output as safety outputs. Additional power on LA+ and LA- ports is connected. I don't know what else should I checked to fix this problem. There is no problem in controler or this specific module just on all of outputs. Hope someone will be able to help.
  19. Is there a way to clear a CPU fault on power up without having to connect to software?
  20. Hi,     I am trying to establish communication between master and slave through modbus rtu rs485. But I am experiencing error code 7378h. I already tried to make the values of Request Interval Timer from 100 to 200 and Broadcast Delat Value from 50 to 100. But the error still persist. Any tips how to solve this issue? There is no error on the slave evices.

  23. Folks, we have a set of Mitsubishi Q12PRHCPU (redundant) running effortless since many years. CPU-A as standby and CPU-B as Control. Recently we noticed BATT low alarm on CPU-B. So we arranged for a spare battery Q6BAT and started the procedure as per manual(attached procedure and flow chart). We did memory copy from Control to standby (as prescribed precaution) and did the Reset of Standby PLC CPU-A. Memory copy from B to A completed successfully 100%. But the BACKUP LED did not turn Green from Red & Error LED kept flickering on standby CPU-A. CPU-B remain in Control but backup LED turned RED. From system monitoring we found that there is a Error 6000 (FILE DIFF.) observed in One of the .QPG (program 00-MDBUS.QPG). We tried to reset it but were not successful. We are surprised that why does the program differs when it was copied from CPU-B to CPU-A using the memory copy. Still we did the VERIFY and found no difference between the programs in CPU-A & CPU-B.  Can anyone explain the cause of this issue and the solution. Please note that the CPU-B is still in control and plant is running. Backup LED on both CPU are red which means (redundancy loss) and error LED on standby CPU-A is flickering RED. There is no error in the CPU-A (Control) -we checked this using the GX Developer. Also attached here are the image of the error and error help. Thanks in advance.

  24. 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
