  2. NX102 SSI encoder problem

    hi have a good time i have a nx102-1200 and a nx-ecs212 module. I connected an SSI encoder to the card and read the position value in the software. The encoder counts 360 pulses in each round and then it goes to zero. I want to use GearIn function and have the encoder as the master and a servo motor as the slave. In each revolution, the encoder pulse becomes zero, and as a result, the servo motor movement is not continuous!!! I want the servo motor to be continuous! In fact, I don't want the encoder pulse to zero every time. What should I do? Is there a solution? please help me thank you so much
  3. 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.  
  4. 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
  5. 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!
  6. 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?
  7. Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.
  8. Hello everyone,   I'm working on a project where I'm using Vtscada Light to communicate with a MicroLogix 1200 PLC. Currently, I can read values from the PLC without any issues. However, I'm facing difficulties when attempting to write values back to the PLC.   Setup: PLC: MicroLogix 1200 SCADA Software: Vtscada Light Communication: Rockwell Driver with a serial port and serial-to-ethernet converter   I'm looking for guidance on the proper method to write values to the. If anyone has experience with this setup or similar, your insights would be much appreciated.   Thank you for your help!  
  9. Hi guys, my site uses mainly Mitsi PLC's & HMI's so not familiar with AllenBradley but i have two Micrologixe 1200 PLC's connected to Panelview 300 HMI's. The machines are twenty plus years old and now both HMI's are barely legible as the screens are so dim.  I want to upgrade the HMI's as they are obsolete but my problem is, the program within the PLC is Password Protected and i cannot read, upload or download to the PLC.  The original manufacturer has been taken over some years ago and no-one knows the password. They have sent me an old program that could possibly work which is not password protected, but i cannot download it to the PLC without the original Password. Can anyone help me?
  10. 1769-IT6

    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. 
  11. Uploaded a program from a micrologix 1400, I added an integer data file. Went to download it, and the processor types were different. I suppose I am just going to change it to match what is on the machine, but why did this happen? The controller was password protected. so maybe it did not get the processor info for some reason. Even when online with the processor, it reads incorrect.  
  12. Siemens and SCADA system

    Hello !  I have a problem. i'm new in tia portal and all siemens PLC. I woudl like to connect my Siemens s7-1200 CPU 1215DC/DC/DC and HMI KTP700 Basic PN to a SCADA system. Can someone give me some advice? Thank you in advance. i use tia portal v17
  13.  I am very green at this and learning online as I have purchased a brand new Micrologix 1400 1766L32BXBA. I am pulling my hair out as I cannot even power an LED or for that matter get any 24 volt reading from the outputs via program. I have even forced them on so shouldnt I be able to see something? I am connected via Ethernet ,Rslinx in concert with using Micro starter software (not lite) and the unit does not show any faults and is in the run mode. I can see the bits forced on the software and on the unit's LCD screen in I/O status. Is there a way to trouble shoot if the unit is bad or I am overlooking something incredibly simple. I do not have any floating inputs or outputs with the common from the power supply and the unit is properly grounded all nice and tidy on a din rail. Like I said I am very new at this so I am sorry if this is a bad question.
  14. Hello everyone, I am a newbie with PLC. I have a Micrologix 1000. The last time I connected with RSLinx easy, however, I change it to DH485 (I do not remember exactly). And now I can not connect it to RSLinx, I tried many times for all types of drivers. Please help me. Thank you very much.
  15. Error PLC S7-300

    Hi all, My system is using PLC S7-300. Now, it is being SF fault. I followed the manufacturer's sf error instructions. I replaced the CPU Module, but it is still fault. Diagnostic of Simatic announced I/O can't access for reading and writing. Please give a solution, thanks Sincerely.
  16. I have 23 Micrologix 1400s and I want to take the same register, N100:99, out of each one and put in a single array in a CompactLogix L18ER. From what I have tried, it only seems like I can only map a range of integers, N100:77-N100:100, to the array and not an individual register to a particular element. (For example, mapping N100:99 from machine 16 to Selected_Model[15]) Can you map to individual elements in an array? If so, are there any instructions on how to do so? Thank you in advance for reading my post!
  17. Good day everyone, First post here so hopefully I'm not violating community guidelines in anyway. I've got a system that has some 50 odd Micrologix 1100 and 1400 in use and I'm currently working on setting up an auto timesync for all of them using just 1 of the PLCs that will be my master time PLC. So far I've put together the logic for all the message instructions with the corresponding IP of the slave devices. I'm running. Into an issue with not being able to terminate/break the message connection on a PLC that I have already synced. Is this even possible to do on the ML1100. Once I get to 16-17 messages DN it starts to ER and will not complete any further messages. What I have is a message instruction ladder with a timed trigger to activate a MSG and write the RTC data then time down and connect and write to the next and so on. When it triggers the message instruction of one PLC it also fires an OTE to trigger the BK of the previous message instruction. However it doesn't seem to be actually cutting the message connection and holds it persistent until a power cycle/download event.

  21. Hello everyone! I would like to connect a Micrologix 1100 with Citect 7.5 via ABMLXEIP (updated to latest version). I tried everything and it is still not working. The Citect and the PLC are on the same subnet and the ping works fine. All the configuration is done as the manual says (I attach the pictures). I have one NIC card and is connected to the PLC. The role is setted to “Server and Control Client”. The kernel has this error: [ERROR] [CORE] [0x07fc] [IOServer] [(GLOBAL)] [ErrorLog()][errlog.cpp] [266 ] Error: Channel offline, cannot talk CINIT 0015 PORT1_BOARD1 IODev_1100 Error_in_CMD-2 16 Generic 000021 Driver 00000020 (0x00000014) Any help would be much appreciated!

  22. Unconverted Ladder Code?

    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
  23. Would someone be so kind as to document a method to clear a fault on a Micrologix 1000. Does one need programming cable and software or is there another method to clear a fault to see if it returns? regards.  
  24. communication

    i want to communicate ml1400/compact logix L24ER to simatic s7200 via ethernet.Please help me with it i am new to it and dont know how to do it.
  25. 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'.
