  1. I have an old Panelview 800 in a system that consists of the PV, a Micro 850 and 10 Powerflex VFd's running conveyor motors. My problems started when one of the motors would not run. It seemed that the PLC was not sending the Run command or the Speed. The problem got worse as I was working on it when two others did the same thing. The current situation is that 8 of the VFD's are getting a Run command and 2 are getting a flickering command. All 10 are getting a 0.0Hz speed command. I connected to the equipment with my laptop and looked at the PLC program and the PV program. I found that in the PV program that all of the user input data, which consists of Motor Speed (Hz), Accel and Decel times and some other timer values for the timing of some conveyor starts and stops, where all gone, set at '0'. this equipment is several years old and predates my presence here. The PLC program seems to be running and passing the commands that it receives to the VFD's. The data is passed to the PLC via Global Variables. I've never encountered this particular problem before. Any ideas?
  2. Hi, I have a problem with Omron PLC and Beckhoff IO. The IO just disconnects in a few minutes and comes back! I received different errors: Link off error, Illegal slave disconnection, process data reception timeout. When I also check "Display Diagnosis/Statistics information" I see errors on all ports A and B of all nodes.  I have called and talked to both Beckhoff and Omron.  I have two NX1 and one NJ101 to test. And I have three EP2318-0001. I have the same problem with all the PLCs and EP boxes. It does not matter if I have one, two, or three nodes. I have tried different revisions of the EP2xxx from the XML file, different settings for the slave, different task periods, and the error still is persisting.
  3. Currently have NX PLC setup as an OPC UA server and an OPC client setup and communicating.  The issue is only tags that do not have a Data Type are showing up in the OPC client.  I have 2 separate OPC softwares connected to this plc through OPC UA and both are having same issue.  If I setup the OPC as a polling service, then all the tags show up as expected.  Does anyone know if this is a known issue with Omron and their OPC UA server, or is there something that I am doing incorrectly (possibly a setting within Omron that I am not aware of)?
  4. NE1A-SCUP02-EIP

    Does anyone have experience with the NE1A-SCUP02-EIP safety PLC? We had a machine shutdown yesterday with a L9n4 error on the NE1A unit. The manual says this is a tag data link error. Does this cause the safety PLC itself to shutdown? I always thought the EIP portion of the safety PLC was only used for status reporting to the PLC. The safety portion is strictly on DeviceNet and is independent of the EIP network.  The CJ2 PLC's error log tells me it had problems communicating with the safety PLC, the VFD, and NX I/O's which were all in the same panel going through an Ethernet switch. 
  5. Hi, I have quite a noobie question. I want to create a function block to do some simple operations on 2 variables. Both variables are In/Outs (see picture attached). How can I make this function accept variables regardless of the data type? Given these is just simple math I am able to use the same instructions in REAL, INT, UINT, etc. But, the function block only lets me assign one Data Type to the In/Out variables.
  6. Data Historian

    Hello, What would be the best data logger for Backhoff automation based automation? Idea is to record some analog and digital tags at certain time intervals. Present them in tabular as well as graphical form and print some reports based on selected time window. I have looked up TwinCAT Analytics and that seems to be one option. But want to check others before making decision.
  7. Memory registers on KINCO PLC

    Hello to everyone. I hope you are doing well. I have a KINCO PLC HP043-20DT. I'm communicating through free-protocol instructions XMT and RCV. The manual states that memory registers SMB86, SMB186 and SMB286 contain information about the state of the reception instruction. I would like to ask if any of you know of the existence of an analog register but with respect to the transmission instruction, instead of the reception. The manual does not indicate it and I could not find any information online. I've sended an email to the manufacturer but, until now, I have not receive any answer. Otherwise, how could I search for this information? I tried through the manual providede by the manufacturer, but maybe there is other way. I would appreciate any information. Thank you so much. Kind regards.
  8. Hi gents, I need to build up a communication between nx1p2 to another omron plc (any type with sql support). This is due to the fact that I have finaly to prepare the plc communication with the sql database, and nx1p2 doesnt support this.  Sorry, i know it's probably a noob question, but I'm a beginner. What type of technology i shoud use to make this connection between NX1P2 and another Omron PLC? Or might be some share some project?  
  9. 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  
  10. 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?        
  11. 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!
  12. 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? 
  13. INDIRECT REGISTER

    i want to use indirect register, but why contact 100,IR0 is not ON, is it my program correct?
  14. 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
  15. 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  
  16. I'm writing a PLC program (Q Series Mitsubishi PLC, GXWORKS 2 Software) for a package sorting machine. The logic of the machine is the following:   Packages are induced in the conveyor. A barcode reader scanner gets the package barcode. Barcode is send to our SMS (sorting management system), it calcules the exit and send it back to the PLC. Package travels to the calculed exit, then is derived into the chute.   The tracking of the products is done by an encoder and a shift register. This means that every memory address represents a physical position in the conveyor. Then, the shift register move the bits representing the packages along the memory buffer, till the bit arrives to an address that represents an exit, so the package can be derived.   My problem is not the tracking of the product, but the product ID tracking:   When a package enters in the conveyor, an ID is set for that product (1,2,...,n). The idea is that this ID is used to track the state of that package, for example if the package was derived in the correct exit, if it has a damaged barcode, etc.   My question is, how can I track this ID along in an efficient way. I was thinking in use the same shift register not moving a sole bit, but moving a larger number for example |1|0000011|, where the first bit acts like a flag that represents the existence of a product and the rest of the numbers is the product ID. When the flag gets to the exit address I can substract 10000011 - 10000000 = 00000011, to get the product ID.   Is any more efficient way to do this ?
  17. 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.  
  18. 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.
  19. 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,    
  20. 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?  
  21. Hello, I have an M2I Top RW (model: 1000WD) connected to a Schneider Modicon M221 PLC. The HMI is connected and I is working perfectly reading data from the PLC via ethernet. I can't seem to find a way to write to the PLC from the HMI. I would like to control the PLC from the HMI, I know this is possible with Fatek PLCs with the same HMI model. please help - how would I create a bit command from the HMI to the PLC? what registers? what inputs in the PLC? thanks
  22. Dear Engineerds,   My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584   Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0)   I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx
  23. 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!
  24. 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.
