  1. hello.   I've been trying to communicate this omron plc CP1L-EM30DT1-D, with a yaskawa inverter cimr-vu4a0004faa. but i can't figure out how to make de correct mov or configuration in de DM. i need to run/stop, change frequency.    some help, please. :) 485PRUEBA.cxp 485PRUEBA.opt
  2. I have a level measurement system by fmcw radar (Rosemount tankradar), for a filling-emptying process, of very large water chambers. Very sporadically, the radar is momentarily lost and measures 4 to 7 feet below the actual level, only when filling the water chamber.  Sometimes the measurement freeze in the middle of the filling process.  Due to the criticality of the process, this behavior is dangerous, as it can cause flooding inside the plant This behavior is very sporadically so we are baffled about the root cause of this problem.
  3. I'm trying to understand the basics of using a serial to ethernet converter such as this Comtrol DM-EIP-2101, with Studio5000 code. Basically I have a weighing machine that only outputs data via RS-232 and I need to send that data to a PC that will process it through a Studio5000 program and have the data displayed on an HMI using FTview SE. Is it as simple as just connecting the serial and ethernet to the converter and it does all the work? Obviously checking ip addresses and firmware will need to be verified. The main thing I am unsure of is the process of passing the individual data packets from the machine to the Logix code on the PC,  things like what the weight of the item was, was it over weight or under, etc....  Would there be an AOI or tags built into the software for a machine like this Checkweigher? I've worked with much smaller items like Cognex Dataman cameras and I know you can just use their AOI that allows you to simply call a tag if you want to display information like if a scanned barcode was correct or whatever. If anyone has done something similar I'd appreciate any guidance. It can be difficult getting the information from the manufactures so I'm looking for answers anywhere I can. EDIT: I guess I should also clarify that only using one or the other (serial or E/IP) is not an option. It will be a serial connection from the Weighing machine to the converter and then Ethernet to the PC.

  5. Modbus Addressing in Weintek HMI

    Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.
  6. Cimplicity Auto Report Generation

    Dear All, I am having a problem with my cimplicity Auto Report Generation, When I Click on Generate Report, it shows "0 values collected" does anyone knows what's possibly could gone wrong here ??
  7. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  8. Hi guys, I have an M221 and trying to read process data from a HACH controller via Modbus 485. In the Read_Var function block I need to configure ObjType, FirstObj, Quantity and IndexData. Slave ID is 3 and I am using SL2. So, say if I wanted to read to following registers, Register #40001, Data Type Integer, Length 1, Description- Sensor Measure Register #40005, Data Type Float, Length 2, Description - Sensor Temp Register #40007, Data Type String, Length 6, Description - Sensor Name what do I put into the Read_Var function ? I am completely new to this and it's just not clear to me. Thanks John

  10. G9SP Configurator

    I am at a client site that has a line with multiple Omron G9SP-N20S safety controllers installed and I need to make a modification to the system.  I tried to install the Omron Configurator and it asks for a serial number, and will not install without one.  Omron said that it is on the CD that ships with the unit, but the equipment manufacturer did not supply any of the CDs.  The only Omron solution is to order a replacement CD, that will take 5 days, which is 5 days too long as there is a hard stop in 2 days.  I have tried entering numbers found on the controller, with no success.  Does anyone have a better way, special contacts at Omron, to et it faster?
  11. Hello all. I have been working with an SLC 5/04 system, which houses various Digital and Analog INs and OUTs, up to Slot 29. I am currently mainly working with Slot 25, an Analog Input: 1746-NI16I. This is a system which has already been set up and has been running for the best part of 8-10 years. This particular card has had some spare inputs, one of which I am trying to connect to. In the Advanced Configuration, only a few Channels are actually "Enabled", and each channel is pretty much slightly different from another in terms of Input Type, Filter Frequency and Data Format. I am trying to set up Input 14, which is Channel 15, to "Enable" it, 4-20mA Input Type, Filter Frequency of 6 Hz and Data Format of either Raw/Proportional or Engineering Units. Now, after I have made my choices, I click apply, and then OK. I am then confronted by a pop-up which states: "Configuration Rung and Data Integer Data File Number: 25 Integer Data Element: 100 Rung to be inserted: XIC S2:1/15 COP #N25:100 #O0:25.0 24 At Program File Number: 4 82" I have the options of OK or Cancel. If I click OK, I now have LAD 4, Rung 82 Highlighted. This First Scan Bit and COP function were already here, but does that mean I have now altered what is being written to "#O:25.0"? I now Download the Changes. However, after all this, I am not getting any Analog input reading coming in from the Live PLC. What is this COP function? What does it do? How do I properly set up this Analog Card?   Thanks for your time, -Jame
  12. Password Protected LS Master K

    I have a customer that has a LS Master K PLC, and he needs me to make some changes to the program. I am not the original program writer so I do not have the original program nor the password. And the company that originally made this program does not exist anymore. Does anyone have any suggestions on a software or a device that can help me either find the password or just bypass it. I need help ASAP Please!!!!! I saw there is a password breaker while i was googling, but the software cost $50, and it looked a little sketchy so I am kind of hesitant to trust 1 purchasing the software and 2 downloading it only my work laptop. Please help!!

  14. Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the  communication. So we want those PLC's to be connected over wifi.  Thanks in Advance 
  15. Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form. Here is the source program that can be downloaded. Other links: VB6 Program: VBA Program: Regards, Garry
  16. PC-PLC CP1E - USB-to-SERIAL cable

    Hi,   I have a self-bought usb-serial cable converter for CP1E. Currently can't connect to my PLC using PC. CX-One says "Failed to the PLC". I am supposedly to use "SYSMAC WAY" as my Network Type in PLC settings?   EDIT: The CPU type is N30   I've checked the following settings: 1) COM number is correct ( as checked from windows Device Manager side) 2) Cable driver is installed, there is no "unknown" driver in my windows Device Manager 3) My RS232C LED in PLC is not lighted up.   Any other suggestions to check settings ive missed out would help, other than buying a new cable for the moment.   Regards, Summerstone
  17. Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU)  for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan.   However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative.

  19. Mitsubishi GX Works Bugs??

    Hello I have been using GX Works 3 for a while now and I have discovered a couple of things, maybe bugs. I have not had any training for the software or hardware so maybe I did something wrong. 1 Labels. If you sort a global label table into any order other than the unsorted order that appears by default you are unable to create, delete or edit any labels. Our Mitsubishi representative discovered that if you click on the column header between 'Data Type' and 'Class' the order does not change but now editing is available. This, it turns out is a really bad idea. It seems the position the label was in when it was created is preserved, I think this is the unsorted order you get by default. If you sort the list and then delete a label it is possible that the label that should be in that position is also deleted. I have attached a small project to demonstrate this. Open the Global Labels notice the order they were created. Now change the sort order, click on the column header I described earlier to make them editable and then delete the label in position 1. For a while I thought this was the only problem but recently there has been a number of instances where I have created a label, given it a carefully selected address only to discover that it is being overwritten by another variable. I have not been able to work out exactly what is going on but I believe it is connected to the sort order of the labels. Also if you sort the order and change an address, have you changed the address of another label? The only solution I have found is to keep label tables very short so they are managable without having to sort the order, that is probably good practice anyway 1 Axis software limits. I have been using a number of axes in pairs, in incremental mode as caterpillar feeders, using FX5U-40SSC simple motion modules. I had a problem that the axis synchronised to follow would suddenly stop moving, the customer was having to power down the machine and start again. This problem persisted for months with Mitsubishi scratching their heads unable to fathom it out and ultimately stating that the problem must be in my code somewhere. It was suggested by the customer that it may be getting to a software limit, I showed the customer that the software limit was disabled in the setup and it was confirmed by Mitsubishi that it was not the problem. guess what, it is a problem. Once the actual position reached the limit of the double word memory it would stop moving. The solution is the take the servos out of synchronisation in order to set the position (datum) to zero every cycle. Unfortunately the drives do not always re-synch on the first attempt so you have to keep trying till it does, this now causes slight variations in cycle times but it works. Andy     Label Test.gx3
  20. There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

  21. NX-105 Received Data

    Hello,  PLC: NX1P  Comm module: NX-CIF105   I am running a serial (RS485) network to control several motors. As a trigger for to read the serial port I am using the ( Ch1 Receive Data Exist) bit, which is an internal bit that's ideally should be energized when there's data in the Receive buffer. However, this bit isn't reliable at all. I am reaching out today to figure out if there's another way to trigger the receive command ( preferably without a delay)    thank you all  Cheers! 
  22. CP1L connected with scanner symbol DS-4308 reading 2D data matrix,  with RS-232 on board CP1W-CIF01 Hi all, need some help because I can't read the information. Let me explain, I have a PLC, " CP1L-L14DR-D " with a RS-232 option borad " CP1W-CIF01 " , a scanner Symbol DS-4308, and I'm trying to read a data matrix 2d barcode (I don't know if that matters). so I build a cable with the next configuration, (one side male and the other female) PORT CONFIG PIN OUT SCANNER CABLE RJ-50 TO RS-232 PINOUT Maybe I'm missing a connection? a bridge? power supply ? ground?   in the program, I only have this to check the communication,       When my reception flag complete (A392.06), my instruction RXD is going to execcute, reading in D1500 the data. if is any error in communication (A392.04) or overflow (A392.07), my port is going to restart (A526.00) (ignore w0.03) with the followign config: (9600, 7,2,E, RS-232C, End code: Received Bytes 3       and I'm reading only, data on D1500 and D1501, and the data makes no sense.   with the configuration of End Code: CR, LF,          can't make it work, I read nothing. and if I change the END CODE: Received bytes to 4,      don't work. and my flag A392.04 go to ON.   PLC HAS 4 PIN SWITCH, ALL ARE OFF The configuration on the scanner is setting to default and then config to RS-232 Standard.   So, what I'm missing?  bad connections? plc don't support? scanner config? program?
