  1. Hey guys,   I know this is a topic that has been discussed before, but I am having trouble finding exactly what I am looking for.. I want to know the most efficient way to record data from my PLC to an Excel file on my PC. I want this to be done without the use of the PLC's webserver.  Specifically I am trying to record vfd speed every 10seconds with a time and date stamp. How can I do this?   Thanks, James  
  2. I am working on something different. I have a Signal Speaker that uses binary inputs to play a certain song based on source configuration. I have to send 24v to the inputs of the speaker. I have 5 of them with 30 different configurations. I am currently trying to do this in ladder logic, RSLogix 5000. Steps done. 1. Assigned the 6 outputs tag names. This is so that I can shift the program to other machines if I have to and I just need to change the slot location, or if I have an output go bad I can move it with ease. This works. 2. I  created the 30 lines of  5 columns to match the binary method. This works.    a. I can manually toggle the output to cycle thru the binary table. 3. Currently working on the logic that when a particular alarm is activated... I turn on the outputs needed to match the binary table. The problem is destructive bit reference on the coils.  I was researching some but don't know what direction to go. How can I call the same output on different rungs? I have attached the .L5X to show what I have programmed. 4. I know the first rungs are wrong. That is what I am trying to fix. 5. Would there be a better way to address this, if so how? Any help would be greatly appreciated.     Speaker_Alarm.L5X Speaker_Alarm.L5X
  3. Hello, I am using Easymodbus library to Communicate with Modicon TM218 PLC. Reading and Writing of Holding Registers working fine. But coming to writing of single bit in data register i am facing Problem. Need to know how we find coil address of a data register. e.g I have to write bit 1 to MW70.1 address. How we do that. Right now i am reading complete MW70 Register and Manipulating it using bit manipulation techniques and again Writing using Write single Register Function. It's working but some times because of reading problem it writes some garbage values. At that time complete system effecting.    Please provide me any solution. Thanks in Advance. 
  4. Hi, I have inserted new RTD module into in my SLC500 as replacement to defected RTD module however the module LED is enabled but the channel LED's are blinking. I have checked the following: In the advanced I/O configuration the module configuration is shown as expected In the data file word format it is not corresponding to the channel preferences What should I do and how to fix the word bits?        
  5. Open data log in HMI

    Hi there! I have S7-1200 controller connected to a Comfort Panel. The machine has some pressure and temp sensors, as long as many valves and other stuff. I generate a daily datalog with some of those variables but, the thing is, I've been trying to figure out how to show these data in the HMI without using a trend viewer. I don't know if it's possible, but I want to be able to see what valves were open (for example) the day DD/MM/YYYY at HH:MM:SS, using the generated data log, kind of knowing the state of single bits at different past moments. I've been searching the web but I didn't find something exactly like this, don't know if I'm doing it properly so I'd like to know if you have done this or you can throw some light on the topic. Thanks in advance and hope you can help me!
  6. How to open .ecx type files. Diagnostic data of the Control logix CPU's
  7. Have been able to exchange data types of BOOL, INT,  DINT & REAL between Omron NJ/NX CPU with Allen Bradley Logix CPU's with Ethernet/IP using the CIPUCMMRead & CIPUCMMWrite instructions. I now have a need to exchange "STRING" variable types. Have tried varions string lengths in the NJ without sucsess. AB default string length is 82 & Omron 256 but I think the difference is the length headder that AB has with within their String Tag type. I know I could convert my strings to an array of bytes & sent them this way, but was looking for a solution to sent them as native strings. Hope someone out there has done this & can share their leg work? 
  8. Hello, i want to create a connection between SIMATIC Manager Step7 and Wincc Explorer to share tags.  I configured wincc to PLCSIM MPI (Create new MPI connection in Tags management) connection but when i active Wincc explorer the connection gone in Step 7 and PLCSIM and when i want to charge my config in the PLCSIM that message 33:17135 shown (SIN_SERV not started)
  9. Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit?   Thanks, Fabio
  10. Hello all, I need to read device memory mostly I need to read R registers from PLC L26. I read device data, but inside of table, I can't find R or ZR registers. Can you help me?  What I did wrong?   BR KS  
  11. NB Data log

    Hi there!  I need to implement a data logging that saves the log in a USB storage for a machine and just started searching for some info about data logging in NB HMIs. Up to now I'm clear about using the Data History function and the sampling method I'll be using but I still have some unclarified doubts about this. 1.- The data log should sample the value of, let's say, a couple of words, each second for an entire day (6:00 am to 6:00 am). NB's manual doesn't say a lot about Storage Type and Buffer Storage in "Save Data History" tab. Does "daily file" mean It deletes the .CSV file daily and it generates a new one? If is it, at what time does this occur? Does "single file" mean it generates a file and won't get deleted? Does this mean the sampling stops when completing the first one? Is "storage period" used to keep the file after the next log begins? 2.- Is it necessary to display the element in order to make the log work? Or can it be placed in a random screen you only enter once a day? 3.- In the "Channel Properties" tab. If I need to get the binary value of a word, do I need to set the max. limit to 65535? 4.- I asume that "Sample points" value doesn't matter when selecting Continue sample mode. Am I right? Thanks in advance, any help is appreciated.

    Dear All, We are using Siemens WinCC 7.0 SP3 SCADA software. We are using two Redundant SCADA Computers that are communicating with PLC (CP-343 module) via Ethernet. One Ethernet cable from each PC is connected to Cisco Ethernet Switch and one Ethernet cable from the Cisco Switch is connected with CP-343 Siemens Ethernet Module.  The problem is after every 75 hours one PC value become still (Freeze).Only One system values freeze at a time. If i restart the system the problem is resolved. Please help to resolve this problem. Thanks  
  13. Data Logging with GT Designer3

    Hello, I am trying to log data using GT Designer 3 and I'm having no luck. I found some sort of online documentation and even going through the myriad of steps still find my self unable to log anything. I am using the melsoft project navigator and GX Works 2 to simulate the logging of just one 16 bit signed word with a constant value. As logging data is clearly not as simple as just specifying D100 or D200 as the devices you want to log, I am hoping someone else on here has some experience on this matter and can help me out.  Thanks for any help in advance.
  14. Hello, I am trying to have single press and double press etc. functionality in my PLC program where for example, single press will turn on the motor whereas double press will turn on the motor for 5 seconds. Is it possible to achieve using ladder logic in sysmac studio, if yes, how? Thank you in advance.
  15. Dear Friends, I have made this video to show you how to take data samples from Delta DVP PLC and save this log file in the Weintek HMI internal memory. The Weintek HMI internal memory is easily accessible using ftp. All the necessary steps are mentioned in the video. The link of the video is given below,    
  16. Hi all, I am currently having a project of polling data from PLC CJ1M using Advantech ECU-1051 IoT gateway which support rs-232 serial connection (Host Link) to poll data from the PLC for data acquisition and monitoring, I would like to use peripheral port since rs-232c port is used for HMI. However, I am currently stuck at make the connection between those two devices. I did setup same transmission configuration between them (baudrate, Unit number, start/stop bits,...). Is there any configuration that I have missed to make the communication works?  
  17. Dword to Float on FX3GE

    Hello! I have a float number (HEX: 3CA01D0F) in Big Endian. It's 0.0195451062. I get it from the sensor and store it in a double word variable. Could you help me? How can I convert DWord to Float? If i use DFLT instruction, It treats DWord as an integer (1017126159) and just gives me 1.017126 e+009 Thanks in advance.
  18. Passwords in Runtime

    Hi I'm looking for a little bit of help. I have a WinCC HMI which will not let me log on with one of the passwords. The general logon and admin both work fine. The Engineer password doesn't work (no display at the top of the screen where the other user names are displayed). There is no warning that the password is in correct or the account locked out (missed in the original programing I think). I have all the project files however I'm using a runtime licence. I would like to log in as admin open the project and clear the password lockout. The issue I have is that I have to use TIA portal and it will not show the project file, is this due to the fact that I have a runtime licence. Is there another way to see if the user name is locked and removed. Like I said I have the admin password which works.   Thanks in advance for any help you can provide. Kind Regards
  19. Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!
  20. I'm editing an old program for a customer that has a zillion user-defined data types. Scrolling through the list trying to find a specific type definition is taking way too long. Is there and easy way to find a specific data type definition? It would help if I knew how to collapse the view so I don't have to scroll through each member of every type. There doesn't seem to be any right-click menu items that would collapse the view.
  21. Hi! I would like to ask how could I send data from PC to CJ1M PLC, by SCU-41 module and RS232 cable, in order to activate an actuator (LED)? In my environment, I have a sensor that sends data from PLC to PC (I'm checking data, "HelloWrld" with Putty), with this configuration: And I have another section where I want to read the data from the PC in ordr to activate a LED I would like when I send for example a letter 'a' trough Putty, the LED activates. How could I do that? Thank you very much!
  22. Hello, I'm using RSLogix 500 application for LAD programming. I would like to convert the float data type to integer data type and vice versa. I tried with the COP instruction as some had mentioned in other forums, but it was not working. So any suggestions on solving that issue would be helpful.
  23. problem with wincc flexible

    Hi guys !! I have a problem with my WinCC flexible. when I create my project with WinCC and step7 the window of Runtime cannot be running!! I use WinCC flexible 2008 sp5 windows 7, 64 bit. thank you so much.
  24. I'm working on simple structured text program which takes in DWORD values, does some math on them and then outputs in DWORD type. What data type should I be using and how can I make this work?  This is one of the lines from the code(everything DWORD) and I get 'operator not supported by DWORD data type' XPos3 := XPos1 + (2*XIncrement);  
  25. Hi guys I am trying to connect a Mitsubishi FX5U PLC to a Siemens WinCC RT Advanced. I did find a document on the Siemens side on how to configure the HMI, but I can't seem to find any instructions on how to configure it on the Mitsubishi side. Any help, sample will be appreciated.   Kind Regards Morne
