  1. Flex I/O Rack

    I am in the middle of doing a retrofit for a old PLC5 and i decided to upgrade it to a Control Logix. With how much I/O I was needing the price of the system was going to be very pricey. So I decided to use my main rack as a control logix and use Flex I/O for my remote racks. I have never put together a Flex I/O rack so I am unsure of what I need for this rack other than my I/O modules and a communication module. Could someone give me a list of what is needed for these systems? 
  2. Problem with array

    Hi Guys! I have a problem with data collection. I use RS Logix 5000 software. I need to collect 11 int value. The sampling frequency is about 2 or 3 second. I tried to make an array but I faild, because I dont find what is correct for my task. I need about 5000 sample each of int value. Anybody have any idea about this problem ? If I have the datas then I have to exporting to an excel table . Thank you if anyone can help me.   T

  4. 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
  5. Hello         I'm new for PLC, I need to set pump turn ON/OFF  in 4 time/day every day => [8:00-8:10]a.m, [11:00-11:20]a.m, [2:00-2:10-14:10[p.m, [5:00-5:20]p.m ** I have Omron PLC CP1E-N30 , Could you advise me, please ?  
  6. My apologies for being a newbie on this, but could someone save me on this... I have a Viper 650 and an eMB-60R controller which I want to control by ePLC connection using an NJ501-1300 PLC unit, SYSMAC Studio with EIP Adept Library for Robot... All are starting up well, and I connect all components to a switch hub...  But following the ePLC guidelines, the IP Address showing on the controller is 172.16.132.111 I change the IPV4 IP Address on the PC settings to 172.16.132.10 and the subnet to 255.255.0.0 but the Adept IP Address Setting Tool on SYSMAC doesn't detect the Robot IP Address, also i tried ipconfig on command prompt which shows a different IP Address IPV4 169.254.197.75 and subnet of 255.255.0.0, I changed the previous setting on the PC setting to 169.254.197.10 with the same subnet. But still PC doesn't recognize. I tried both configurations if ACE Software can detect it but the same ACE can not detect it also... Appreciate any thoughts on what's wrong in my configurations. Thank you.
  7. I am using CJ2M PLC.I want switch on a output for certain time by a timer and holding bit if interlocks satisfied.If interlock not OK timer has to hold the time and output should be off. if again interlocks OK again output has to ON upto balance time completion and has to give timer done output for reset holding bit.please suggest.
  8. Hi, I am trying to do a merge move on 1S Servo. The condition are as follows: Task: Move 2 in(absolute value) and then Move back to 1 in (absolute value). I have to do this move 10 times in a row.  The application is material leveling after dumping in the mold. The only question i have is if I use just MC_MoveAbsolute command, the only buffer mode for transition available is velocity. Is there a way i can do it with position. I dont want to stop when I can go from 1 to 2 and 2 to 1 again and again. Its time consuming. But rather a nice oscillation motion without stopping to mimic leveling. Can anybody please help me out with this problem.   Thanks
  9. CP1E-N30DT with Hyperterminal PC

    Dear Expert, i'm issue to do communication CP1E with PC via RS232. im try to use plc for sending information and receive by hyperterminal pc. after googling some information there have multiway to success. by the way until now cannot settle. please expert share completed setup that's work: 1. communication cable from PLC - PC (my information use pin (2,3,9 jumper 4&5) - (2,3,5 jumper 7&8) 2. sample program that works (im using TXD & RXD with memory D1000 to keep data) 3. connection cable to PC using MOXA Serial to USB converter. 4. plc serial setting (default: 9600,7,N,1,Host link) my target to give instruction to printer to start print. printer need ACSII code. if this communication success i'm will convert all data to ACSII by ACSII convert function.   thanks,
  10. PC send data to PLC

    Hello, i'm newbie for plc. i want to ask about PC/computer send data to PLC CP1E with serial communication (RS232). my wiring cable is: PC                         PLC 2                             2 3                             3 5                             9 4&6    7&8                               4&5 and if i send data from PC to PLC, my indicator in COMM is blinking. i think the cable have no problem. but if i send data from PC to PLC, the memory is not same as what i send and whatever i send data, the memory didn't change. i will attach my ladder diagram. what should i do?    New folder.rar
  11. load cell SP4M-7Kg

    Hello guys, I have a system of 3 load cells (SP4M-7Kg) attached  to a Micrologix 1500 analog inputs. in the same PLC i have 3 coils for a vibrator, each vibrator is working with signal generators. and the load cells with an external 24vdc Power Supply. i see my load cells readings fluctuating too much even with the vibrator not working. if it is set lets say 70 Grams it is jumping from 68.4 to 74.8 going up an down never never stabilizes in one number, so i suspect am getting noise somewhere put a 100uF capacitor PLC inputs for the load cells but weight just increases more and more. How can realize where is the noise comming? what can i use as a filter? how can i improve this system? should i changed it to digital?   any help welcome! thanks.  questions?    
  12. So I did this simple Function Block, pretty simple, and yet it keeps giving me this error, after a bunch of failed combinations the error persists, without telling me whats wrong. And therefore won't even allow me to download the program to the PLC (CJ2M CPU31) or even simulate.   I heard it's a simple thing to fix but I really dont know how to, since I'm quite new to this. Here's the function block  itself in the picture and the programming inside it, although since it gives me no errors, i don't think that would be the problem
  13. Jiskoot modbus

    Does anyone have experience with a Jiskoot Insight controller? Im trying to establish communications between it and a MVI69-MCM. I have checked and rechecked all my settings. I am not sure what I am doing wrong. Thanks
  14. Hi everyone, I just want to layout the structure of the question. I have a GOT2000 (GT27* series) that I have hooked up and communicating with an Allen-Bradley PLC. I have established connection and can pull out certain tags values from the PLC program in RSLogix 5000. While I can read the tag values, I cannot modify them (in certain conditions).  So let say that I have a User-Defined Structure named "Smoke_Detector" and here are it's available members: Smoke_Detector:   - ALARM (BOOL)   - ON_TIME (DINT) * DINT in Allen-Bradley but Signed Binary 32   - Battery_Life (REAL)  My question is that while I can read and display the tag and its members through the following:   - LAMP for Smoke_Detector.ALARM   - Numerical Display for both Smoke_Detector.ON_TIME and Smoke_Detector.Battery_Life But when I tried to modify the values via a Bit Switch or Numerical Input, it does not operate on them.  However, if these tags are members are just standalone tags, meaning that they are not within a UDT in RSLogix 5000, then I can operate/ modify them just fine.  Here are the things that I have tried: * Making sure that the permission are set to Read/ Write in RSLogix 5000 * Making sure that the tag definition in GT Designer 3 follows the structure where @[channel]:[Network #]:[Station #]::[Tag instance and member (e.g Smoke_detector is the instance and Alarm is member] Any possible insight and input are appreciate! 
  15. Hello, I need to Synchronize two 4kW motors connected to their own individual AltiVar VSDs. To put it simply the two motors are pulling cables on a pulley and when loaded the motor's slip and the speed varies. I have an Omron CP1L-EM PLC and 2x Omron Rotary Encoders ( E6C2-CWZ5B encoders - 360 PPR) - connected to each motor,   What is the best way to read the pulses from the two rotary encoders then convert to RPM? 1) Using  PRV or PRV2(883) instruction,  - this would be the best option as it would convert the value to RPM - however, can I use this instruction on both Counter 0 & Counter 1? 2) Or read the raw value from  Counter 0:  A270 (connected to motor one's encoder) Counter 1: A272 (connected to motor two's encoder) Convert the pulses to RPM - then compare and adjust? 3) Or using CTBL. - is this a useful instruction for this application?   Once I get the RPM speed from each motor - I can then do a compare instruction - see if there is a mismatch and if so send a scaled analogue output to the VSDs to correct the speed if required. (10-50Hz) What would be your recommendations? any help would be most helpful. Thank you.

  17. Homing servo motors

    Hello everybody, I have a question about homing servo motors. I have a project with new servos from Omron and I would like to know what is the best way to do homing for the servos and how often. Before when we have servos with encoders I was making special homing sequence and was calling by some event. I heard that new servos from Omron pretty smart and remember own position without batteries. So with this 'new generation' of servos what is the key to keep machine robust, easy for motor replacement without useless programming stuff. Regards, Scotty

  19. 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 !
  20. Retrofitting old PLC5

    I have a customer that is wanting to upgrade his old PLC5 to something newer. I am still pretty new to the PLC world and was hoping to get some insight on possibly what might be the best fit. I still do not know a lot on this sytems. What I do know is that there are 5 input cards 2 output cards 1 analog input and 1 analog RTD card. Also the customer has a screen that uses rsview and he would still like to use that. Anyone got any suggestions on where I should start? Or even what other information I would need in order to find the perfect fit?

  22. Hi guys,  I have been trying to sync up my RSLogix 5000 tag to GT Designer 3 (GTD3) objects but I noticed that GTD3 only recognize certain native data types from Allen Bradley Logix5572 Controller (Model 1756-L72).  In the documentation that I found, it show that certain AB Native Tags are transferable to GTD3 Data Type (See the attached file "AB Tags to GTD3 Tags" ) One of the User-Defined Data Type from the RSLogix 5000 that I am trying to sync to Text Display Object in GTD3 is called "UDT_MY_CLTR_INFO" here is it's hierarchy of inheritance from RSLogix 5000     Name                                                                     Force Mask                                                                                   Data Type MY_CLTR_INFO                                                     (...)                                                                                                 UDT_MY_CLTR_INFO      MY_CLTR_INFO.NAME                                                                                                                                           STRING           MY_CLTR_INFO.NAME.LENGTH                                                                                                                      DINT           MY_CLTR_INFO.NAME.DATA                                                                                                                           SINT[82]    In my exported tag which is a CSV file, it doesn't list the sub-classes MY_CLTR_INFO.NAME, MY_CLTR_INFO.NAME.LENGTH, and MY_CLTR_INFO.NAME.DATA, it would only list MY_CLTR_INFO.  How do I link up my "Text Display" Object in GTD3 with the tag "MY_CLTR_INFO.NAME" whose Data Type is STRING and GTD3 does not have a STRING Data Type?  I appreciate anyone that took their time to read my problem and any attempt to help me out. Thank you. 
  23. I currently have certain amount of Recipe data located in form of Excel file on to a PC with static IP address. Is there a way to get that data inside the Nj501 without using an SQL server as I currently have NJ501-1300 which doesn't support SQL. I am okay to send data to the SD card I currently have on NJ PLC as it is easy to get data from SD card to the NJ501.  If there is any example code or a link that helps me create i would be helpful. Thanks in advance. FYI: I am currently using NB10 HMI with NJ PLC.
  24. Omron cp1e power indicator turns off

    The plc runs for a minute and then the power turns off while the supply voltage is ok. I was sure that it is for the power circuit problem inside the plc. As I had a spare power circuit of cp1h and I checked it had same voltages output (5vdc, 24vdc & 0), I replaced it. Now I cannot connect it with my laptop to change to run operating mode. Could anyone help me?
  25. Adept Omron Smartvision MX

    Hello, new user here also a new user to all Adept Omron products as well. I have seen a lot of information based on the Omron Smart Controller EX - mainly connecting the controller to the Adept Ace program. I do understand that the dongle is needed to enabled into the controller, but can this same process be the same for the Omron Smartvision MX?  Thanks.
