  1. I know nothing about HMI's or Crimson software.  I'm in I.T. and we had to change the third octet in the IP address and gateway on all devices at our warehouse.  I extracted the file on one HMI, changed the ethernet info, and clicked send.  That HMI that runs a carpet machine works perfectly.  I went to the second carpet machine.  Extracted the file changed it's ethernet info, clicked send.  It came back with all ---- (dash's) instead of zeros, the carpet machine won't work.  I kept messing with the file trying different things, and inadvertently saved over the original extracted file!!!!!  So I thought I'd extract the file from the working carpet machine and loaded it on the second carpet machine.  I get the same issue, all ---- (dash's) on the HMI and you push any of the buttons on the front of the HMI and nothing works.  These are Allen Bradley MicroLogix 1500 running Crimson 2.0 HELP I don't know how to resolve this issue.  I would have thought both HMI's would have been the same!  HMI all dashes.eml HMI all dashes2.eml
  2. I have a micrologix 1100 PLC as well as a weintek HMI all connected through a network switch for them to communicate between each other, however I'm having an issue where the Micrologix Controller will not retain its IP address once I set it through Allen Bradleys BootP tool. I can set it through the tool and then go into RSlogix 500 and communicate with it and all that, but once the controller is turned off the IP address goes back to its factory setting of not showing an IP at all. Any suggestions/ ideas as to what I'm doing wrong?
  3. can anybody Know how to control stepper motor using PLC
  4. Hey, I have a 1763 L16BBB...when I plug the 1762IF20F2 analog card in, I get a 0189h error code. Any help would be appreciated. Currently looking at doing a bootp on the plc to get online...no ip
  5. Have a micrologix 1200R 1762-L40BWAR.  If anyone could help with providing the following information: Need a communication port with single receptacle that will mount through the door of electrical enclosure and then the communication cable (6 to 10') that will go from the com. port to the micrologix. Thanks
  6. Does anyone have an example piece of ladder logic, created on a Micrologix 1200, using ASCII to READ and Write to a serial device?  I am building a ladder on a Micrologix 1200 that will send data to an old CNC once a certain ASCII instruction is received on the PLC.  For example, when the machine spits out an ASCII "1", the PLC will see the "1" and send out a three digit number depending on a sequence of discrete inputs.   Thank you,
  7. Hello, I'm new to PLC Programming, with just a simple course about the basics. I've got a micrologix 1400 PLC which seems to have had its program wiped when the battery was replaced. I've had the company that supplied the machine it runs send me the program for the PLC. However, I don't have any software to communicate with it, and download the program to the PLC. I was hoping some one here could help me out and direct me towards what I will need to do to get the new program installed on the PLC. Thank you 
  8. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  9. Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James

  11. Communication

    ivan da silva posted a topic in Allen Bradley / Rockwell Automation

    good evening. Someone can give tips on how to configure and physical the application with the following items: Advanced Interface Converters (AIC +), PanelView800 2711R-T7T A and MicroLogix 1500 Programmable Controllers My doubts are about the configuration of the communication, and I have doubts about the physical environment and protocol to be used.  
  12. I have multiple PVP 1500's on the same network. From the one in my control room i need to be able to see what user is logged into what HMI. How would I address the system tag of another HMI on the same network would I use the IP address? thank you for any help in advance
  13. Hello :I'm the creator of an Android HMI app,  I recently added Ethernet/IP connectivity with MicroLogix and SLC AB PLCs, but I have only been able to test it with a MicroLogix 1100.I'm really not sure if it works with SLC or with other MicroLogix models.If someone could try it, I would appreciate it. To access the test, from the Android device, open this https://play.google.com/apps/testing/com.suppanel.suppanel on the web browser and install the Beta version.On the application you have to open the "EIP MicroLogic SLC Test" panel that contains some instructions. Thank you very much !
  14. Hello,  I have a micrologix 1400 plc connected to a length measurement gauge. The gauge sends an analog value to the plc to an analog input. I convert the value into a dimension and send it to F8:0. but I need this value in three different steps in the program. Since i just have one element of float (F8:0) is there anyway i can store the value in a different location or create more floating point tags eg. F8:1. F8:2 ?    Thank You   
  15. Good evening(here at least),    I am working on a senior design project that requires the use of a PLC. Due to budget we've had to settle for an older Micrologix 1000 from Allen Bradley. I've managed to get the software running and connect with the programming port. The problem I have right now is trying to decipher how I would connect a load cell(Such that it causes a condition change at a certain weight). Ideally I would want a load cell amplifier connected to an analog input, but I don't think the 1000 has support for that. Would it be possible to use something like the HX711 amplifier(digital output) to be read on one of the input pins of the micrologix? I wanna say the pins don't read a pulse modulated input and I can't seem to register for the AB knowledgebase as the site gives me a web error. I'd appreciate any feedback.  Thanks in advance.  
  16. I got into a project were they have 20 panelviews plus 1500 around the building, and they want to be able to serrate the displays accessible by the users based on the physical location of the panelview, for example Room1 should not see room2 but can see room3, at this moment we have a complete application with all the screens that have been downloaded to all panelviews, in order to avoid maintain 20 different ME applications I would like to ask if any of you had this problem before or any ideas on how to go forward with it.   Thanks
  17. Dear Sir, Kindly Tell me how to use encoder with micrologix 1400. Thanks

  18. Keyence CV-X Controller and Siemens S7-1500

    PLC_007_BOND posted a topic in Siemens

    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

  20. Hello,  As the title indicates, we have a micrologix 1400 that has been installed for a long time.  Recently it faulted out on 71h and was in Remote Mode.  Do these PLCs revert to Remote Mode when in a fault condition?  We placed it back in Run Mode and everything worked fine, but how did it get to Remote Mode in the first place? Thanks,  J 
  21. I have a "paddle wheel" style flow meter that I am trying to wire to my Micrologix 1400. It is a three wire device and there is a tag on it that says it can run at 6-36VDC. So, naturally, I thought to wire this to one of the HSC inputs of the Micrologix directly. I hooked the ( + ) on the meter to 24V, ( - ) on the meter to common, signal to the oscilloscope, and ground on the scope went to common. I see a small 60Hz sine wave @ like 5mv when the wheel is not turning. When the wheel is turning I get a small square wave but in the same mV range. It is not a nice smooth square wave either its all jumbled up with the 60Hz sine wave.  I hooked this thing up to a transmitter and scoped the signal and ( - ) in parallel with the wheel - I get a nice smooth square wave signal when the wheel turns. It is only at 4.5V though. My questions are? Why does't the paddle wheel give me what I am expecting directly? Also, what is the voltage range on the pulse that a micrologix will see? I am assuming that it will not count a wave with a 4.8V amplitude.... Thanks for your help in advanced! neech   
  22. Hey guys, I am working on an application that tracks irregularly spaced PET bottles on a conveyor line and then blows them into boxes waiting on the side of the conveyor. I believe I have working logic, but I am having issues with the encoder at operating conveyor speeds. I believe the best logic for my project is to use a photoeye to detect the presence of a bottle (a one-shot makes sure it is only detected once), and then "store" the "presence" of the bottle in a binary file using an encoder pulse to trigger a BSL function. Using this logic, the bits in the file are analogous to a real, physical location on the conveyor, and I can just monitor specific addresses in the file where my real-world air nozzles are located. My current problem is that as my conveyor speeds increase, the PLC begins to miss pulses from the encoder. During my initial set-up, I took data at very slow speeds to experimentally determine how many pulses were between the photoeye and each air valve, but when I run at full speed, I only detect about 70% of the pulses detected at slow speeds. Not good. Althought the "skipped pulses" seem to be proportional to the detected pulses at slow speeds. I am using an encoder that only runs at 60ppr, so I would think that my PLC (MicroLogix 1200) can handle this...I did the math before I purchased the encoder and thought I found the pulses to be infrequent enough that the PLC wouldn't miss any. My 2 trains of thought: 1) I need to use an interrupt for each encoder pulse since they occur so quickly (utilizing an EII), which I am not fluent in. I can find instructions to intitially configure the EII file, but I am unsure of how you are supposed to correctly set up the ladder logic to utilize the interrupt. 2) There is an electrical issue. The encoder I bought uses pull-up resistors. The resistor value I selected only drops the detected voltage to 14V from 24V. Is it possible that the encoder does not spend enough time in the "off" state at high speeds because of this high voltage value? OR does the usage of a resistor introduce a time-lag into the system which further complicates the issue? Any help would be appreciated, Thanks!
  23. Hello all, I am still fairly new to this forum and PLC's in general. I am trying to connect a EA9 touch panel via Ethernet to an Allen Bradley Micro Logix 1400 PLC. I am using Ethernet over serial because I need the serial connection to program while using the touch panel. I have given the Panel the IP Address 192.168.1.20 with a subnet mask 255.255.255.0 and I have given the PLC the IP address 192.168.1.10 with a subnet mask 255.255.255.0. The panel is not communicating with the PLC and I have very little knowledge on the subject, anyone's help would be greatly appreciated. The picture on the top is from the PLC and the picture on the bottom is from the C-More program for the panel.

  24. S7-1500 FW v 2 / Profinet issues non-Siemens devices

    PLC_guy_in_Yokohama posted a topic in Siemens

    Hello: Has any body encountered Profinet IO cyclic communication establishment problems between the latest S7-1500 PLC with firmware 2.0 or later and non-Siemens Profinet devices which had previously passed conformance testing campaigns? Thanks for your comments.    
  25. I have been searching on how to import logic 500 tags to connected component workbench for panel view 800 project and striking out is there a way to do it? Project is to replace optimate  OM440  HMI connected to MicroLogix 1500 with a panel view 2711R-T7T. Replacing the controler is out of the question at this point. Tom
