  1. Omron CJ1M-CPU13-ETN to .NET Framework

    Hello People, In my school we had an assignment to program a Sorting machine using an Omron PLC and CX-Programmer. Now we got the assignment to make an HMI that we can open on our own computer (Windows 8.1) so that we can control various things of our program, such as reading and writing bits, and other data (To the PLC obviously). Now I only have very little experience in reading and writing data from a PLC (Using a PC), I have used the libnodave library to connect to a Siemens S7-300 PLC. With this I managed to read and write bits, and also read and write data to a DataBlock. We wrote this program in Visual Basic 2013 using the .NET Framework with the libnodave library as an added extension. Now I have searched far and wide on the internet but have not come across any good examples of how to do this with an Omron PLC. So I hoped that I could get some advice from you guys. What I'm asking is if anybody here has maybe a link to a guide/ example program/ manual that could get me forward? And if I can easily get this done with Visual Basic, by adding an extension, could anybody tell me which extension this would be? And where I could find it? I appreciate any help. :D Thanks in advance, BitsNBytesRookie
  2. Good day I have a scenario where I need to connect to Ethernet ST-lite units to an L-series PLC. With a Q-series you will use the Modbus card and create a Intellgent Function Module to do this and specify the header addressing for the unit. With the L-series, you have Modbus on the build-in Ethernet port, but how do I now setup and specify the addressing for the for the ST-lite unit? Please help...

  4. OMRON PLC's and CITECT Comunication

    Hi All; I am struggeling to get my CITECT to talk with my CJ1MCPU12 with ETN21 module. I can ping the IP address from the citect PC and also connect CXONE using ethernet with supplied IP Address. I do not have FINSGATEAY installed as the PC is Windows 8 with CITECT 7.4. Any Ideas would be most welcome as I am drawing a blank. My settings are OMRON ETN21 IP: 192.168.0.3 Unit number: 0 Citect SCADA Primary Server IP: 192.168.0.24 Citect.INI [OMFINS] Source = 1/3/0 (not too sure what this should be...)

  5. Problem of CX-PROGRAMER

    When I open the cx programmer v.9, I am getting the following message: "could not initialise cx server. check installation". Can someone help me? I have been reinstalled the omron twice but cannot resolved this problem Thanks
  6. Hello, I am looking for Omron PLC's bit set instruction, which is similar to Mitsubishi's, like, in Mitsubishi PLC: Set B1000Z0 if Z0 is 10AA, then B10AA will be set. has Omron's instruction set contains such functionality? In my application, PLC will receive a number for example N(i.e. a sequence number), and I want to set the set the Nth bit in a memory block (W or so). Many thanks in advance. Xing
  7. OMRON NT31 HMI

    Hi, I have been communicating OMRON HMI NT31-ST123-EV2/EV3 for creating, uploading and downloading program screens with NTST4.6 but today I have received NT31-ST123-EV3-QR HMI but it could not be communicated with Support Tool. Can any one sort out the problem? Attached is the snap shot of error message.
  8. On Ethernet/Modbus-TCP, if a device is a Master, can it get polled by another Master? i.e. Can it act as a slave as well. Thanks, Arun
  9. need help with SCADA database. moving 50k points

    Hello, Let me preface this. I have used this site many times when searching for issues and it has always been helpful. This is my first post here. I have been programming PLC's, HMI's, VFD's etc etc for 15 years, fairly complex stuff. I have also done lots of SCADA programming but more just for basic interface, monitoring, basic parameters changes, logging, etc etc. I am not facing a setup where I must do a large recipe/batch data transfer and I am confused as to what the best path is to achieve this. I have fairly basic knowledge of VB script as I have not needed to use it very often. Here is the problem I am facing. The SCADA package the customer has is Omron CX-Supervisor. The network is all Ethernet Based 1) I have 26 moulding machines on the plant floor2) There are 50 different moulds that are moved around from machine to machine3) Each mould can run 1 of 10 different colours4) There are 100 differing cycle parameters for each colour/mould combination =50x10x100 = 50 k points for total machine that = 50k x 26 = 1.3 million ! What the end result will be is this. From the SCADA operator terminal they would like to be able to keep a 'master set' of these settings, call up a mould/colour combo and see the individual parameters. Then they would like to edit individual parameters and download to each individual machine, or all at once. I do have a PLC at the Main terminal that was used for translation of the old serial network to ethernet. All of the serial connections have been removed so it is basically doing nothing. I could use this as a "master" for holding parameters if needed. What is the best way to go about this. Create a database, use the built in recipe manager, use PLC here as 'master storage". I feel once I get down a path it will make more sense...I just don't want to pick the wrong option and have to redo it all. Keep in mind my PLC coding is vastly superior to my knowledge of database manipulating and VB coding ThanksDan

  11. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.

  13. I successfully read the input and output of OMRON PLC CPM2A with Indusoft web studio (IWS) by using OMPLC driver. I have select OMPLC driver (Serial Com). Then configure a driver worksheet. The driver worksheet is the place that PLC tags are associated to InduSoft tags. I successfully read the I/O but I failed to write the I/O of PLC by using IWS. Can you help me? It is difficult to find OMPLC Standard Driver Sheet (SDS) for control relay output block (CROB) and Analogue output block (AOB). The attached diagram shows My Standard Driver Sheet (SDS) setup. Thank you for your kind cooperation. Zack Malaysia
  14. Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance
  15. Connect OMRON CJ1H to GSM modem

    Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding?

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(

  18. Hello all, I am trying to connect a barcode scanner to my plc using a 232C in the serial1. The scanner is a motorolla ls3578 fz, with the following parameters: Transmit code ID: yes Data Transmission format: Data/suffix Suffix: CR(1013) Baud rate: 9600 Parity: none Hard/software handshacking: none Stop bit select: 1 Ascii format: 8 bit RTS Line state: high Prefix: none In order to send data form the scanner to the plc, I use the RXD function block with the following parameters: First receive word: D300 Control word: 0100(hex) Number of bytes: &10 All the communication settings of the PLC are the same that the scanner ones. PROBLEMS 1)When I scan something the scanner beeps as if a transmission error occurs, and the data is ignored. 2)The A392.14 never comes ON and. POSIBLE SOLUTIONS Type of barcode: Now I am using a Code39 barcode. Is it OK? How can I implement the suffix? I have a software that allows me create new barcodes, but I don’t know what kind of data do I need. With 1234567891013 the 1st problem occurs. With 123456789 nothing happens. Communication settings: maybe my communication settings are not well defined. I attach you the file and maybe someone find out an error. Thank you up front! rxd.cxp
  19. MAD42

    Hello all I have a task to connect a auxitrol l20d to my omroan plc i have these moduls: CJ2M - ID211 - OC211 and MAD42. The l20d should go from 18-5mA and when it hits 5mA a alarm should go off, my problem is how can I adress the inputs/outputs in the MAD42. My wiring to the L20D is this : The l20d is connect to A1 5-6 with + at 5 and - at 6 How can I adress the anonlog inputs in MAD42. Could anyone help me, or maybe give me an example program? Thanks in advance ;)
  20. Hi everyone, I'm facing problems implementing the Easy modbus-rtu master solution kindly provided by PMCR. i'm working with a CJ2M, and i have a SCU41-v1 connected to 5 AC10 series Parker drives, using modbus at Port 1 (Protocol Macro as indicated in the manual- 2 wire). Everything works ok after powering up the system. Unfortunately, after a few minutes, one of the parker drives freezes communication. An hour later....another. And so on. If I reboot the drive, powering it off and on, it starts communicating again. Any ideas about what might be causing this? Thanx.
  21. Hi, Is there any good documents out there on how to download to a NS15 Omron HMI from CX-Designer via Ethernet? Thanks, Andrew
  22. ModbusSlave.ACD

    Hi everyone, I want to connect Allen Bradley 1756-L63 cpu (slave) via RS-232 port to ABB CI-853 (I don't have Prosoft MVI-56-MCM that can easily solve my situation). The only way that I found is application ModbusSlave.ACD (cig-ap129_-en-p.pdf). Do I need AIC+ converter (1761-NET-AIC) or can I connect with cable (DB9-to-RJ45)? Is there another way to make this connection? Regards, Luka
  23. Im trying to control a baldor VFD trough modbus RTU with cp1h/cp1wcif12 using the solution posted here which for me works really fine but the problem comes when I turn on the motor (500hp 440v), the cable gets induced and adds noise to the communication causing errors when reading. I already try to use shielded cable and it gets better but still causing errors. In the solution posted in the link above shows how to connect the cp1w-cif12 by connecting only SDA- and SDB+. So my question is, should I connect FG to the VFD rs-485 ground as well to reduce that noise? Any suggestions are welcome
