  1. thesis project

    Hello, For my thesis i'm using a beckhoff cx9020,a sunnyboy and a sunnyisland with rs485 communication protocol sma net. One of the things I need to do is to log everything from the sunny devices realtime. and here is where my problem starts. I am using rs485 to communicate with the devices via plc but I don't find any documention for what i need to request or send to get usefull data. does anyone here have an idea? Yours truly Jonas Vanhulle
  2. Data Historian Speed

    I was just curious on which type of data historians are considered fast at retrieving historical data.  For example, if I wanted to trend a tag at a one second interval to review an event that took place a year ago and compare that to the same tag in real-time, what historian does this the fastest?
  3. Can anyone advise if there are data structure #s associated with each of the data types in Logix?  Example if it is a Bool, I believe Logix advises it is a 32 bit number.  But is there an "under the hood" data type reference number for each Logix data type?  I.E.  if it is a Bool, that is a RA data type #1, if it is a DINT, it is a RA data type #2, etc.  
  4. Hey all, I've reviewed a number of threads regarding converting one data type to another and I have something I'm working on that I'm stumped on and haven't found an answer for yet. Without getting into the details, I need to get a DINT bit value from an entered decimal value. A user will enter in a whole number in an entry box and then it needs to get converted to the number of whatever bits that the DINT number holds. For instance: # Entered Variable Bit Value -----0------------------0 -----1------------------1 -----2------------------3 -----3------------------7 -----4-----------------15 etc... I'm looking for a fairly clean way to do this, with perhaps just two or three instruction blocks to handle it, if possible. I can provide a screenshot of the HMI and the logic (4 rungs) if necessary. Any suggestions or advice from the group would be greatly appreciated!
  5. I'm trying to use CX-Server to pull data from my Omron CJ2H PLC directly into Excel. I'm able to pull a single element into excel, but when I try to pull more than one element, I get a huge strand of numbers. Is there a way that I can set up a single point in DDE Manager that'll hold all the elements that I need, then in excel have a formula that will pull out specific memory elements. Specifically I'm trying to pull data from D7200-D7399, and put each element into a separate cell it in a chart that ranges from B3-K22 This is what the formula looks like when I copy a point into excel =CDMDDE|'C:\Users\... ....cdm'!'\New Point 1' I didnt know if I could put something at the end of each string to call out specific elements, but I keep getting "#BadPoint" =CDMDDE|'C:\Users\... ....cdm'!'\New Point 1'!'D7200' =CDMDDE|'C:\Users\... ....cdm'!'\New Point 1'!'D7201' ... =CDMDDE|'C:\Users\... ....cdm'!'\New Point 1'!'D7399' Any help would be great
  6. I forgot how to do this. If I put in let's say 1234569632<cr><lf> how do I store the carriage return line feed along with the number in my ST file??? 1234569632(chr$13)(chr$10) something like this, but can't remember. Thanks
  7. Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.
  8. Hi friends, I am a little new to WinCC. I am using a WinCC RT Advanced license within TIA portal v13.1 I need a little help in my current project as described below. I am attempting to create a faceplate of a solenoid valve,, The "Valve" is a user-defined data-type with the following 4 elements 1. Cmd - or command. - Bool 2. Cls_Fb - or Closed -Feedback -Bool. 3. Aut - or Automatic Mode -Bool 4. FTC - Fails to close -Bool. I tried the following procedure as described in TIA portal help.. Method -1 1. I created a User-defined data type called Valve comprising of the above 4 bool elements. 2. In the graphics I made a image of solenod valve with one rectangle (solenoid) and one polygon for valve body. 3. Under the Faceplate Properties (See figure attached) I inserted a property ang gave it the data-type Valve as above. However, when I drag a property from the 'Contained objects list' to the interface side, it is not getting substituted. such as the Rectangle_1 's background color I try to associate with the interface property Valve.Cmd. It does not get assigned when dragged. Since this does not work I tried another approach, Method -2 I attempted to declare a variable tag of UDT type 'valve' in the faceplate's tab Tags. I found that it is not possible to declare a local variable of User-defined types here. Please guide me how to proceed. Thanks for looking in and best wishes for your success. Regards, Raj S. Iyer
  9. Hi friends, Can anybody tell me when to use a local-Static variable and when to use a Local Temp variable whilst creating a Function-Block in S7 -1500 using TIA portal. Thanks for looking in. Best wishes.
  10. Automation professionals, I would like to read the display values of a red lion DP700 in a control logix PLC. I was able to successfully integrate both devices through EtherNet / IP and I am geting the corresponding values in a DINT register in the PLC. But the problem is that the value in the PLC register is not in the same format as in the DP700 display. The display reads the length of a product in inches like 288.484 etc. Where as the value in the register is a 10 digit number like 1133526516. For sure, there is a definite correlation between these two values but I am not able to figure out the exact relationship as a function of a formula. I have given below 25 data pairs for your analysis. I tried to find out the scaling factor (slope and offset). The scaling that I found fit the first 10 records but did not fit the remaining 15 records Can you help me to find out the relationship between the ? # DP700 PLC register 1 288484 1133526516 2 288627 1133531202 3 288631 1133531333 4 288739 1133534872 5 288741 1133534937 6 288742 1133534970 7 288746 1133535101 8 288757 1133535461 9 288776 1133536084 10 288796 1133536739 11 241060 1131482972 12 241043 1131481858 13 241027 1131480809 14 241032 1131481137 15 241055 1131482644 16 241038 1131481530 17 241078 1131484152 18 241025 1131480678 19 241030 1131481006 20 241037 1131481465 21 241040 1131481661 22 241023 1131480547 23 241053 1131482513 24 241041 1131481727 25 241077 1131484086

  13. CJ1W-TC001 PID question

    What is Omron naming convention for PID settings? I need to adjust the upper MV limits for PID running on CJ1W-TC001 installed on CJ1M-CPU13. Looking at the CJ1W-TC001 Operation Manual I am not really sure which values would these be. I guess Omron naming nomenclature is a bit different than what I am used to. It seems that the Manipulated Value Monitor is just feedback, which value would I need to set or modify to adjust the upper MV limit?
  14. Hey All, I am trying to do some data storing on a PanelView+ and the built in data logging doesn't quite fit my needs. I was looking into the possibility of creating my own ActiveX control for doing this. Is it possible to create custom ActiveX controls for Factory Talk? If so, are there any tutorials for doing so you recommend? Also, are there any sites that have custom ActiveX controls to download? I realize this may not be the easiest thing to do, but if I could create my own I could use it for various machines and would make things a lot simpler in the long run. Thanks
  15. Hello, I am having troubles configuring my Data Station Plus to be able to read my Vacon VFD registers over a Profibus network. The network is configured from an Omron PLC. I have communication but i do not know how to map the tags on Crimson to be able to read what the drives are doing. I am most likely thinking my offset on the tags that i have set are the main problem. Any input/ suggestion would be great thanks Specs on System: -Omron PLC CJ2M w/profibus PRM21 -Omron HMI NS-12 -3 Vacon NX VFD's -Data Station Plus w/profibus module
  16. Hello all, I am trying to get around a lot of manual inputting by exporting a routine and opening it using excel, but looking at the file that excel shows I have a couple fundamental questions 1. when excel opens it and "creates a schema', can I save this in a format that will allow me to import it back into the program? 2. Since I am mapping data using add on instructions, the table excel has created becomes quote complex, with no clear point of reference to where my Input tags are going to go. We are doing this because someone thought it would be a good idea to put a SCADA based control platform over the top of an AB control system, so we have to exchange thousands of points of data back and forth with their system. I created the mapping AOI blocks to be able to manage the file structure a little better in the routines, but that still leaves me with copy and paste thousands of tags into the AOIs. Has anyone developed a good way to create logic, or modify logic using excel? While I can hold my own with utilizing the RS5000 platform, my excel experience is limited. The processor is a 1756-L75 Thanks

  18. I am getting this error. How to resolve this?
  19. Hello All, I want to read data from a Control Logix PLC, into a PLC5/60, using Ethernet and a MSG instruction in the PLC5. When verifying the MSG instruction in the PLC5, I get an error message. "Target Address in invalid". Once I figure out how to do this I need to replicate it in another PLC5. Scope is to read the status of 4 paint pumps controlled by the CLX. If any of the 4 stop, the PLC5 needs to know, because it is controlling the paint application equipment. Source data resides in a Control Logix 1756-L63. The tag is INT type, 4 elements long, and the name is PUMP_STS_B2. The IP address of the CLX is 4.2.6.230. There are 2 ENBT cards, one in slot 1, and the other in slot 3. 4.2.6.230 is slot 3. PLC2,5 / SLC Mapping has been created in the CLX. File=421 Name PUMP_STS_B1 and File=422 Name Pump_STS_B2. The file mappings represent a binary file created in each of the PLC5's B421:0~4 in Booth 1, and B422:0~4 in Booth 2. The PLC5/60 is Enhanced series E model using the Ethernet side card. The IP address of the PLC5 is 3.26.5.61. I also created MG file types in each of the PLC5/60. MG420:0~19 in each processor. This was necessary to use the MSG instruction in the PLC5. I have searched the forums for examples of how to do this with no solid results. I am trying to follow the best practices of reading the data into my PLC so anyone who follows can tell where it is coming from. While the IP addresses are not closely related they should be able to communicate. I say this because all of our PC's are on the 4.2.6.XXX network on a 255.255.252.0 sub net and we have no issue communicating with the 3.26.5.61 IP address. Any help and advice would be greatly appreciated. Regards, Mike Carter
  20. Hi dear all , i need some helping .. I used CJ2M cpu31, then i want to send data (example D100 = 2000) to PC ...essentially i want send value 2000 to my PC.. wherein the PC and PLC conect via internet IP .. What should tool/software may i used ? Thanks before ..
  21. I'm having a bit of difficulty with the MSG function on a logix5000. I'm simply trying to get a REAL value ("BH5_Flow") out of another logix5000 and assign it to a tag in the PLC. I've created a MSG function and created a new tag "BH_5_Flow_MSG" for the message, and created "BH5_Flow_M" for the value that will come from the MSG function. When I click the "..." button to bring up the config, I put the following in: Message Type: CIP Data Table ReadSource Element: BH5_FLOWNumber Of Elements: 1Destination Element: BH5_FLOW_MIn the PATH tab, i then put the following in: Path: LocalENB, 2, [iP ADDRESS OF SOURCE MACHINE]When I test the edits, I then get the ERR bit activate with error 16#0004 when the message rung runs. Anyone got any ideas where Im going wrong? I've practically copied another MSG instruction from further up the ladder but it doesn't seem to work
  22. I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance!
  23. Hello guys, i would like to know if is possible keep always active the run command in a vf drive and for stopping the motor only send 0 reference. It´s possible??? because I want to program a ramp function in my plc for start and stop one motor. could someone tell me how to do this type of control please?.
  24. Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi
