  1. Hi everyone , I need your help !!! I am currently working on a project where I have to control a stepper motor (oriental motor AZD CEP) with a proface HMI. To do this I use implicit Ethernet IP messaging. The problem is this: when I change screens, I lose the connection between the two devices. After 20-30 seconds, the connection is reestablished. I've already spent two days on it and I can't figure out where the problem is coming from. Does anyone have any idea what's wrong? If you need additional information or screenshots to understand, let me know. Thank you in advance for your help.
  2. NJ to ML1400 CIP Read

    Omron NJ processor needed to Read data file from Allen Bradley MicroLogix 1400 PLC over EIP. This method uses CPUCMMSend Function block to send a CIP message to the ML1400 to read 64 words of data from file register N32:0 Since our NJ PLC is using a CJ1W-EIP21 SIOU module for the EIP connection the RoutePath also needed to be determined.   Explicit CIPUCMM Send to Micrologix 1400 PLC to Read      Function Block Variable Name Variable Name Input Description          CIPUCMMSend               RoutePath RoutePathName 01/ When using an EtherNet/IP unit a connection is routed through the CPU backplane port (01)     #10/ Unit number of EtherNet/IP unit + 10 (Unit number 00 + 10 gives #10)     02/ When communcating through EtherNet/IP the communcation port route code is 02     192.168.1.14 Target IP address of Micrologix 1400 PLC         TimeOut   UINT#20 Timeout time         ServiceCode ServCode 4B (Hex) PCCC Service Code - CreateSocket (75 dec)       When configuring a MSG Command in RS Logix 500 as "unconnected MSG" and "Generic"  RqPath ReqPath: (Hex) the given Service code and Class ID are 4B (75 dec) and 67 (103 dec), respsectively.     ClassID 67     InstanceID  01 Should be set to 01 (1 dec)   AttributeID 00 Do not use the Attribute ID   isAttributeID FALSE           ServiceDat SrcMessage: (Hex) Command message to the Micrologix 1400    SrcMessage[0] 07 Number of bytes in header is 7 (dec)   SrcMessage[1] 01 Second byte of Vendor ID   SrcMessage[2] 00 First byte of Vendor ID   SrcMessage[3] 0d First byte of CIP Serial Number   SrcMessage[4] 0c Second byte of CIP Serial Number   SrcMessage[5] 0b Third byte of CIP Serial Number   SrcMessage[6] 0b Last byte of CIP Serial Number   SrcMessage[7] 0F Command Byte (15 dec) (Will be the same for read and write)   SrcMessage[8] 00 Status Byte (Normally 0)   SrcMessage[9] 4C LSB of TNS/TNSW   SrcMessage[10] 00 MSB of TNS/TNSW   SrcMessage[11] A2 Function byte (Protected Read with 3 address fields)   SrcMessage[12] 82 Number of bytes to be Read (130 dec)   SrcMessage[13] 20 The index number of file (32 dec) in our case N:32   SrcMessage[14] 89 File data type (137 dec) is type integer, N   SrcMessage[15] 00 Start element number (If it was 02 then would start at N32:2)   SrcMessage[16] 00 Bit level address         Size SrcSize UINT#11 Size determines how many elements from the SrcMessage are sent (17 dec)         RespServiceDat RespDat:       RespDat[0..10]   First 11 bytes in the response are the header we sent but will return a command byte of 4F   RespDat[11..150]   The rest of the response data is the requested information from N32:00-N32:64 but is byte swapped          AryByteTo               In   RespDat[11] Takes the response data from after header as the input         Size   UINT#139 Size determines the number of elements input from RespDat.

  3. Good morning Today I have the honor to present you our project, on which we have worked the last months. We have been annoyed for years that when creating software in special machine building, sometimes the same/similar messages are created over and over again and then they are described similarly or the same in the machine documentation. The thought, if the mechanical components are mostly the same/similar, the error description can also be "copied" (at least initially). An Excel table with the error numbers seemed to us here a good beginning, however it would be practical, if with each message text also still the description to the message in a document, including pictures, tables etc., were deposited. This was then the point where we first thought about an online tool. This also solves problems with collaboration and makes it possible to work together. Also additional languages can be added if a machine is to be rolled out to a new market. PLC-Alarm is a young Austrian startup founded by PLC programmers to ease the handling with machine messages and their descriptions. Therefore we tried to solve the following problems besides the creation of an error list: Working together on message lists Hierarchical creation of message lists Inheritance of message texts and message descriptions to lower-level projects Adding additional message lists to make message texts more variable. Adding a description to any message text in any language via Google Docs. (Connection to Microsoft Word-online is in progress) Document template for uniform presentation Combining all message descriptions into one machine document file. Highlighting used messages to avoid having unused message text in the message list. And to shorten the machine document file. Upload a file containing the used message numbers to mark them automatically. Any export options for PLC, SCADA and HMI systems possible. (Currently optimized for TIA Portal only). Suggestions for additional features welcome As mentioned in the last point, currently only exporting for a TIA Portal text list is possible since the first customers are also programming on Siemens. But we are looking forward to extend this according to customer requirements. Do not hesitate contact us via e-mail. We invite you to test our free web applications and leave your feedback. The application is already successfully in use at the first customer and we are looking forward to more users.

  6. Good Morning, I connect using a TCPSocket a remote node with my NJ501-1300. In order to test communication with the remote node I use a telnet communication and send from it messages to the remote node: it work correctly opening the connection and then sending all messages I want; the connection will close only at the end of the communication session. WHAT HAPPEN ON NJ? On NJ Open connection whit remote node; Connection is open; Send first message to remote node; Receive correct answer from remote node; Send another ore the same message to remote node; Receive an unknown command answer from remote node. WHY??? To solve previous problem I need to: Close the open connection; Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; Close connection Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; close connection and so on... Could someone help me to solve this problem opening the connection only once and then close it at the end of the end of communication session?!   THANK YOU
  7. Hello Everyone. We have Schneider TM241 PLC Along with Citect SCADA System at 100MWp Solar Power Plant to monitor and control various equipments like Inverters, Switch-Yard, MFMs, Weather Monitoring Systems etc... Government Authority here asked every solar plant to control the generation as per the instructions by Load Dispatch Center, for that we need to implement logic to control Generation as per requirement. For that we are controlling generation from inverters by giving them generation setpoints calculated by PLC using PID function.   But we are facing one problem while using PID. (FB_PID of Toolbox Library)   Suppose we need to generate only 60MW out of 100MW. So we set PID setpoint to 60MW and according to that we get PID output and according to that PID output value we provide generation setpoint to every inverters.   This system works very fine until the clouds comes into the picture.   Now suppose Setpoint of PID is 60MW and PV is also near about 60MW, and suddenly large cloud comes over plant and block solar radiation.   In this case generation comes down to 10MWp(or any value below 60MW), So output of PID will Increase and keep increasing and settle at the Maximum value. but without solar radiation generation value stays very down then Setpoint.   Now suddenly Cloud moves and again solar radiation increase, but the PID output is maximum at that time so, Suddenly Generation goes from 10MW to near about maximum capacity (100MW) instead of 60MW, and then it will slowly comes down to 60MW.   We need to rectify this generation shoot up when cloud moves. Anyone have idea how can we solve this problem or anyone have programmed PID in this kind of situation.   Is there any function block available to do this correctly like function block of PID with two Reference or something like that...   We are using TM241 which is CoDeSys based PLC.
  8. Hi everyone! I have a question to all of you guys - do you ever use any software or online tools to manage your automation/electrical engineering projects? I have worked in a number of companies and have seen various scenarios, from using excel tables to run multi-million dollar projects to using proprietary SW for every little tiny project. Unfortunately I do not have experience working for any major big integrator and am very curious how projects are managed at this level (and if every engineer likes the way it is handled).  Additional question - does anyone have ever used a software to automatically generate the PLC code? I know some companies develop products to generate the "skeleton" of PLC program and I think it is a great thing to have.
  9. Hello! I have a problem with Allen-Bradley High Speed Counter card 1734-VHSC24/C. I need to make changes to the configuration parameter .OnValue1 (DINT) during the system is running. Now, for changing the parameter value, I need to switch off the module and this can not be done during the line is running. I think that maybe this can be done using the explicit messaging. I could not find information for this from internet, so now I ask you to help me with this item. If anyone have experience or knowledge of this, please help me. I do no have experience using explicit messaging. My configuration: Studio 5000 Logix Designer V24.00, 1756-L71S V24.11, Ethernet/IP, 1734AENTR, 1734-VHSC24/C countermodule.
  10. Batch reports Comfort Panel

    Hi experts,   I need to generate the batch report for my project without any script , i check in our forum but previous links are all deleted. Can any one please provide sample backup please ?     Because i am really confused to achieve the batch process. In Report generation we can print the PDF file which the data's are already entered in that particular page but my requirement is, i need to take print out the following details 1.The parameters should be stored in report from my batch start to batch stop with date and time. 2.And also i want to take report for some particular dates (that dates should be selectable from HMI)  Any idea how to do this?      Please see the attached image (example) and am badly need this please help me  https://youtu.be/tvao1QLlHnM
  11. Hi all,  At my work, we are unfortunately still using GX IEC Developer 7.04. All of a sudden I can no longer open any project at all with my GX IEC Developer. I can start the program just fine, but as soon as I choose a project to open I get "cannot initialize communication manager". And after this, I get another 2 "cannot restore parameter file. param.tmp not found" and "cannot restore transfer setup file! cnct.tmp not found!". Doesn't matter which project. And I have opened these earlier with no problem for years. I have tried reinstalling ALL Mitsubishi software on my PC. And restarting PC. I can't find a link to any other changes I have done on my PC either... Does anyone have any idea how to solve this? Best
  12.

  13. Hello I have a SLC5/05 and a Microscan MV40 smart camera which receives commands to a TCP port. Is there a way the LSC 5/05 can send a command to the camera using the MSG instruction or any other instruction? I would appreciate any advice 
  14. Hi every body! Now I use a Q-motion controller Q172DSCPU with advanced synchronous control method. I try to synchronize 4 axes with Axis1 as command generation axis. The problem is that the command generation axis current value is not be cleared to zero after restarting the cycle. It should be cleared to zero to be kept within stroke limit during the process. Thanks in advanced

    This is an example (with code) on how to cycle user messages on the Keyence KV-D20 display. The code is written as a sub-routine that is easily incorporated into a Keyence KV series PLC. The code is proven to work - I've used it many, many times. A brief rung-by-rung commentary explains the basic operation of the code.

  18. I am running a very large step based program on an NJ plc.  I have several status and alarm messages that I need to display on the screen during the auto cycle.  Right now I have set up unions in the PLC for the faults... but this is a very large program with a lot of possible faults.  I'm up to 9 16-bit array unions already.  It is just getting really cumbersome.   I would like to just write an INT to a data area for each fault and status message.  That way I can assign each step a 5 values to be used for faults and messages (ie: step one can use numbers 1-5, step 2 can use 6-10, etc) .  Then I want to have the NS display a message from the string table based on the value in the data area.  Is this possible?
  19. I am having issues trying to send an email using the message instruction and the ENBT module. Attached are snippets of my configuration of my message instruction and the error code that i am getting. I had IT look into it on their side and i shouldn't have any network switch configurations that is blocking the successful delivery of the message. Anyone have any ideas what could be the issue? Thanks!
  20. hi all, I have CPU 315 - 2 DP. I can't download program from S7 manager to CPU. I have message Help on Message 33:17075 Description: All stations on this subnet must have the same value for the transmission rate. The interrupt may not be assigned for other hardware components. The MPI addresses in the network must be unique, meaning each address may only be assigned once. The local Station address must also not be greater than the highest station address in the programmable controller. Remedy: Call the program "Setting the PG/PC Interface" in the Control Panel. Under "Properties" set the transmission rate used in the network and adjust the local node address to match your network. Set a station address for your programming device/PC which is not higher than the highest station address in the network. Shorten your HSA address to match the PROFIBUS addresses of the slaves used. i put all the interface setting PC/PG on default but i've the same message. what i must do ? please some help.
