  1. Sample Pid Program

    Hi All, Could anybody send some sample PID ladder to control temperature/any process value? Regards L
  2. Cimplicity 8.0 Alarming

    Hi Guys, I am new to Cimplicity SCADA but I was familiar with HMI. Now my requirement is to separate / dedicate the alarms to each process or setup in the respective screen. Prior they have made all alarms to fire on all screens/ all process. Now idea to separate the alarms in the respective screen. In all screens on top, if I click on alarm object, its properties are Link Container and it has Link source file as xxx.cim and Link source Object as Alarm. Please guide me from the beginning, how they configured the existing alarms also I am not understanding. I need help please. Thanks a lot.

    Hi Hope experts are there in Cimplicity please help me.... I need help in understanding OLE in CimEdit and VB Scripting, if examples would be better
  6. Cimplicity HMI/SCADA

    Hi Somehow got Cimplicity 8.2 demoversion. Now I started learning it.... How to read a PLC tag to Cimplicity. I have Omron PLC & HMI experience, where PLC register address i will assign on the HMI bargraph object suppose. so based on PLC register's value bargraph will show the display. How to achieve the same in Cimplicity screen and run to see the display of bargraph Also any material/sample code helpful for learning basics highly appreciated.
  7. Career sugestion

    Hi Now I am looking for your valuable suggestion what would be the best for my career growth. If i am looking for new job openings on my present PLC / HMI developer skillset, not many openings and that to they would ask for more travelling. Being mother, I'd like to prefer no travel and like to do job at one place. So I am looking to enhance my skillset in the areas of MES, Flexnet. Could you please suggest some good trainings in MES, or what would be best for me. Thank you very much.
  8. Transmission error bit in PMCR

    Hi All, I have 13 nodes where I am polling 13 PMCR instructions to read and write data successfully with a counter.I have generated error for nodes in problem/not connected physically/comms break when I use/ selected all 13 nodes. This i have done with keep instruction with the input of transmission error falg (1633.15 as Unit 5) and reset with normal complete flag(1634.11). Node #1 error is getting detected at its PMCR's execution completion and before to next PMCRs start. simple way to tell. when Polling counter is at #2 , then transmission error flag is high, when slave 1 not physically connected or comms problem case. I may not use all 13 nodes sequentially and randam I select what ever i require from HMI, called as required in my program. In this case i am getting problem in generating errors. I will attach code for better reference. Kindly go through and suggest me some ideas. Thanks Untitled.cxp
  9. Hi All, I want to know what is face plates and add on instruction features in RSLogix 5000. Because, I am a Omron PLC Programmer and some body told me that with RS Logix 5000 has much better capabilities using faceplates and AOI (Add On Instruction). I really like to know what is face plates and AOI (Add On Instruction) and how it is used in programming. Thanks
  10. Hello Can you please share me the PC programming cable details to MicroLogix1200 PLC. I have the PLC MicroLogix1200 with me but no programming cable. So I want to make the cable if you can help me in pin connections. Also One more is that I have bought Panelview component C600 model AB HMI. For this too please let me know PC programming cable details, Thanks Lakshmi
  11. PowerFlex 40P

    Hi Kaiser, Thanks for the reply. Could you give some more guidance on WebDock DAQ ?
  12. Hi All, I am using AB Power Flex40P VFD, where encoder can be connected to 40P. PLC as master and VFD as slave for start and stop commands for our application. After power up, machine is homed and then allowed to run the motor reverse and forward to reach certain distances for Gun which is mounted on the machine continuous. During this process, when machine working the whole day we want to keep the machine position as same with respect to all the speeds. I am using StepLogics, with which VFD can be stopped after reaching commanded destination, without any external stop command, by this i can achieve good accuracy. There are Pos tolerance,Pos Gain and Pos Fliter parameters playing major role in accuracy. what could be the best combination fo gain, filter & tolerance so that accuracy /position would be same with respect to all speeds and Accel/decel. I'd appreciate your early reply.
  13. 40P Drive

    Hi, I am using Power flex 40P drive for positioning control. My requirement is to run 3 position steps (Step0, Step1 and Step2) with corresponding Preset Fre0,1 and 2 in reverse direction from Home. I saw manual saying that E222 Positioning Mode set as Preset Input directly commands the drive to any step from Home reference. But this is not happening when I set E222=Preset Input,P36=COM port, P38=Positioning Mode. Then I am trying to give 8192 register as 34 value to move Step0. But this is not happening Why and where I might have done mistake of setting to achieve this. Also I want Rev direction from Home for all the 3 steps. Please help me ASAP
  14. Modbus speed for 13 slaves

    Hi, I am using Modbus PMCR Instruction to communicate with 13 slaves. Each PMCR is having 50bytes of data transfer (Receive+send using Function code 17). I have kept all times in protocol macro as minimum as possible 0.1ms each and maintaining 38.4K baudrate. Whether this baudrate would be OK to transfer without any problem and how will come to correct times to set in macro? Another question is now with a counter I am polling 13. To send a data to any perticular selected slave is taking 2sec time. I am thinking to reduce this time. How could i improve? My aim is to make 0.5sec and whether is possible? somebody could help me?
  15. Modbus PMCR Polling

    Is any other method for Modbus PMCR polling other than using a counter? Time b/n polls on a slave in 13 slave network is 1.5sec. I want to reduce this time.
  16. Modbus speed for 13 slaves

    Please find my original code for separate read and write using Function code 8 and 4 in second section. Also find Read& write in one PMCR using F17 in first section and both in same cxp file. Also the protocols i have attached for F17 and read ,write separately. It will be a great help if you could reply me as soon as possible. CJ1M_PMCR_JCH.cxp Modbusprotocol.rar
  17. I was searching for PIDAT (PID Auto tune) hidden formula how in PLC might have implemented inside the instruction. Because I have one embedded task to be done with PIDAT function which is not built in. PLC suppots built in PIDAT function If any one had the formula, can you please share to me. Thanks
  18. PIDAuto tune Formula

    I actually wanted a c code for this PIDAT
  19. Modbus speed for 13 slaves

    The slave is a embedded card, which is connected to field IO rather than to Omron IO card. so over modbus, i am reading & writing status of inputs and outputs. Such i have 15 cards to communicate. Earlier i made read and write separately (13 for read + 13 for write) with 26 counter which was taking more time nealry 3sec. But i was continiously polling with that also and I don't know how to write only when data is changed. So later i changed to 17 code to reduce the poll size. I am also attaching the ladder code. could you tell me how would i do that. Could you please guide me.... CJ1M_PMCR_JCH.cxp
  20. PIDAT

    Hi, I want to implement Omron PIDAT similar function in embedded C. I checked for function block if any available so that i can pick up.....but not found. Can somebody help me?
  21. Transmission error bit in PMCR

    Hi! I am not seeing any browse link as shown in the picture.Only seeing Attachment editor and Options text and nothing else. Or else please provide me your Id as I will give my mail Id. lakshmi.chamarthi@gmail.com
  22. Transmission error bit in PMCR

    PMCR! How to attach a file while sending personal mail? There is a text shows "attachment editor" but no link to attach a file
  23. Transmission error bit in PMCR

    I appreciate your efforts. I have tested this on machine but couldn't help. Also I tried selecting only slave 1 and rest of slaves unselected from HMI i.e, polling counter always 1. In this case I tried disconnecting physical slave hardware from communication, but error was not set in PLC ladder. Even if there is a sequence abort flag setting error, immediately I have seen Normal complete flag resetting it. I am not understanding this scenario that why Normal complete flag becomes high even though Slave physically not presented. Could you please look in to help me. Thanks
  24. Transmission error bit in PMCR

  25. Transmission error bit in PMCR

    Hi PMCR, Thanks for your immediate reply. I have tried out but didn't work out, may be something i am missing. Actually what my analysis is if i execute all nodes PMCRs and generate error, then it will fine. But I want skip to excute PMCRs for not required ones and execute only required ones, as i know these slave numbers can selected from HMI and i am bypassing as said in program to increase the speed. But generating errors to only required/selected nodes is becoming problem. I would appreciate if anyone could look into code and give some suggestions. Or in other words, how to generate slave error, when couter value is at respective node considering all the slaves programming done but selection of HMI slaves only shoulld be in active state.This i have done bypassing of counter successfully but generating error is the problem when counter at same slave id. Thanks for the help!
