  1. FX3U-485ADP-MB

    markyspicer posted a topic in Mitsubishi

    Hi! I have some concern dealing with the FX3U-485ADP-MB device which will be plan to install and a total of 17 modbus devices(Chinese brand converter 4-20mA to RS485) where going to communicate. I'm new to this feature of FX3U family and I'm using GxWorks2. Is there anyone that can guide me through this device/development? Is there a program block for this like the one I have been use for analog modules(FX3U-4AD)? Looking forward to your help!   Thanks a lot! Marky
  2. I am trying to export the Modbus points lists from a DAServer in Archestra SMC but I am getting an error message shown in the attached image. All options are greyed out and I cannot export the points list from the PLC node. I know there are points configured on the PLC node because data is updating the the InTouch application. Any help you can provide is greatly appreciated!
  3. Anyone ever have this happen:   launch Network Config.. Go online, upload the devices that are there:                         The NJ, The NA HMI, and a Ethernet/IP Generic drive (The EDS has been installed) ..  that's what you see above ..Click OK , and a "NO" to start a new list ... and get:                                                                       Really .... DUH! .. where are the devices?                            Anyone have any idea why the 3 devices didn't show up on the network line?     Thanks much... Regards, Michael

  6. Hi again I browse through half a dozen mitsubishi manuals but turn up nothing for mitsubishi plc cross-communication. In this project there are about six L-06 plc:s. All are on the same ethernet network already, communicating nicely with the SCADA system. Per today information is (temporarily) exchanged via the SCADA system. Here is another hole in my knowledge. Namely how to correctly setup communication between these plc:s. I plan to continuosly exchange some 50 bytes of information. I would be grateful for some pointers and/or perhaps a reference to a manual. Cheers to all of you //

    kingkumak posted a topic in CX-Programmer

    Hello everyone, in my project I have to connect CJ2M-CPU34 with CJ1W-SCU31-V1 module to external device (see technical specifications in attachment). The CJ2M should read and write a few values from the external device. Unfortunately, I dont have a chance to try this communication before, just during system start. I never make any project on Modbus. Anyone can send me a program to communicate with this device, according to documentation in attachment?   38RBS_Modbus_1.pdf Modbus_2.pdf

  11. Simon was a game that I remember well when I was younger. This simple game can teach us how to program sequencers and look for inputs in a correct order. I believe that this can be a great leaning problem for PLC’s and HMI’s. You can learn about bit manipulation and sequencers in the PLC. HMI timing and control is also shown because of the time to play sounds and update to the next random set of lights.   Here is part of the post …   Building a PLC Program That You Can Be Proud Of – Part 5   Simon is a memory game introduced in 1978. It has four coloured buttons, each producing a particular tone when it is pressed or activated by the device. A round in the game consists of the device lighting up one or more buttons in a random order, after which the player must reproduce that order by pressing the buttons. As the game progresses, the number of buttons to be pressed increases. If the wrong button is hit the current game is over. Our game will have a high level score and a current level score.   We will be using AdvancedHMI to communicate Modbus TCP to the Automation Direct Do-More Designer Software Simulator.   YouTube Video of the game being played: https://www.youtube.com/watch?v=QrfnDHCeJjk   Note: The PLC and HMI programs are provided free of charge and are an excellent way to learn PLC / HMI programming.   Here is a quick review of the programming series so far. If you are new to the site, we recommend reviewing the other parts in the series first. In part 1 we looked at writing PLC programs to control a traffic light using discrete bits and then using timed sequencing using indirect addressing. Part 2 used indirect addressing for inputs as well as output to control the sequence of pneumatic (air) cylinders in the program. Part 3 and 4 we returned to the traffic light application and expand our program significantly. We looked at the sequence of operation using Input, output and mask tables.   The first thing that we will do is look at the HMI programming.

  14. I'm designing a PLC system in which a Micrologix 1400 talks Modbus TCP/IP with three Modbus TCP-capable SCR controllers. I've never done Ethernet/Modbus TCP communication using the 1400, so I'm asking the following questions: 1. Can I connect the 1400 PLC and the three devices to an Ethernet switch and configure Modbus TCP communication from the devices to the PLC (data collection only) ? The switch will also be connected to the customer's DCS, receiving the data from the PLC and the three devices. 2. Can I connect the Ethernet port on the1400 PLC to the Ethernet switch directly, or do I need some kind of Ethernet interface, like the 1761-NET-ENI ? 3. The system also includes an HMI, connected to the 1400 PLC by RS-232 communication. Any issues with communicating with the HMI and doing Modbus at the same time? Your help in this matter would be highly appreciated. Thanks. Ron

  15. Modbus RTU

    Luka0204 posted a topic in Mitsubishi

    Hi, I have LJ71C24 modbus module as a master and slave device with the RS-485 Half-Duplex (Modbus RTU). If someone could tell me what is the correct wiring and what are the correct parameters for such communication (Transmission control, do I use echo back parameter..???). Right now, I short-wired SDA-RDA (with A of slave) and SDB-RDB (with B of slave). Also, I am trying with the predefined protocol using Schneider Modbus protocol. Is this ok? Best regards

  16. CJ1M CPU11 how to set IP adress?

    Chickenkiller91 posted a topic in CX-Programmer

    Hello, I have to work now with a cj1m cpu11. I would like to connect it to a ns10 display. My first obvious problem is when i made the project in cx programmer, that unlike in cj2m i wasnt able to select the cpu unit in the IO table and set the ip adress. How do i need to set the ip address? im reading an omron guide, but it is confusing, and so long, i only want to set the ip address :/. Also how can i set the fins network to 2? On the cx-designer i set the network address:2 and the node adress:40. I know that the 40 means the end of ip address. Thats why i want to set the plc. How about the network address 2?  Help is much appreciated. Thanks!
  17. Developed new software Modbus_TCP_communication. I. Modbus_TCP_Communication 1. Program Modbus_TCP_communication designed to exchange information between your Android smartphone and controllers PLC with Modbus/TCP. Information is exchanged through the computer and the router, wherein the router is connected via Wi-Fi network with your smartphone, and computer connected via interface Modbus/TCP with an PLC controller. The software has the following modes :  - modes read/write of words holding register (FC06);  - modes read/write of words input register(FC04);  - modes read/write bits coil(FC05);  - read the contents of the directory computer;  - reading contents of a text file of computer   etc. The program Modbus_TCP_Communication consists of 2 parts: - Modbus_TCP_Connection.apk - is implemented on the smartphone -   setting and monitoring of parameters and variables on the smartphone for   information from the controller; - Server_Send_Receive.exe - implemented the computer - server computer for sharing   information with a smartphone and a PLC controller according to the protocol   Modbus/TCP, computer is  Master for exchange of information,   a controller PLC is Slave 2. IMPORTANT !!!  The smartphone communicates with the router via Wi-Fi network. Wi-Fi router can be connected  to local or WAN networks. Obviously, the router must be properly configured  by the system administrator. It is also obvious that the device and the router must belong to  the same Wi-Fi network.   3.

  18. Hi all, I am trying to control and/or read values from Schneider Altivar12 VFDs. Via Modbus on a AB Micro850 PLC (using the Connected Components Workbench Software). There seems to be two ways to do this with the Micro850, either with messaging (using the msg_modbus instruction function block) or with the Modbus mapping feature. I have a list of the communication parameters (see attached fileATV12_Communication_parameters_BBV51917_1.4IE05b.xls ATV32 Communication parameters_a1.2ie03.xls) But I haven't had any experience with Modbus and I am not having any success. There is not very much documentation about how to do this, If anyone can help me who has done this or knows how to do it I would appreciate it.  
  19. Hello everyone! I need your help.  I use the PLC: Q06UDEHCPU and the module: QJ71MB91. I programmed in the program GX Works 2 I instaled a library of "QJMB91ModbusSerial_V120 (FB - QJMB91ModbusSerialMaster)" and using it wrote temperature sensor interrogation program. The sensor is interrogated by the channel 2 and has the following switch settings:  Switch 1 - 0000; Switch 2 - 0000; Switch 3 - 0000; Switch 4 - 0A04; Switch 5 - 0000; which are specified by the PLC parameter in GX Works 2. I found an example of writing a program to install the switch settings in the user manual QJ71MB91 using ZP.UINIT instructions. I wrote a program to this exemple. Not prescribed bit address, which should be established when the program is executed (M0) (ZP.UINIT  "U4"  D0  M0). I wrote: ZP.UINIT  "U4"  D0  .  After executing ZP.UINIT instruction PLC stops working, blinking error, settings module is not install. How can I write a program to configure the Switch Setting?

  20. Serial/Modbus communication

    Luka0204 posted a topic in Mitsubishi

    Greetings, I have L02CPU and LJ71C24 (for serial comm) and they act as a master. For slave I have some energy analyzer device. Device has a Half-duplex RS-485 serial interface (Modbus RTU protocol). Master only needs to read some data from slave. My question is: What protocol should I use for mentioned communication (MC, Predefined, Nonprocedural, Bidirectional)? I saw that if I use Predefined protocol I can select in Predefined Protocol Library, under the Manufacturer, Schneider Electric - MODBUS - 03: RD holding Registers. Is this OK for my type of communication? I will try to do some testing between LJ71C24 and QJ71MB91 (who will act as a slave), this or next week, but it would be helpful if someone can tell me correct protocol for my type of communication? P.s. I am using GX Works 2. Best regards, Luka
  21. So here's the problem I'm facing. I've recently started working for a company that has two facilities. They have lots of old equipment/PLCs, plus some new stuff. We undertook a project to upgrade the network infrastructure, and replace all the old programming terminals (Some had Windows 2000!) with a new standardized programming terminal, all sharing a common image. We've installed these new computers, and they were working great. Recently, we switched all the licensing to a Hyper-V based server, using FactoryTalk Activation Manager. Right off the hop, there was issues with one of the sites (let's call it site B). Site A is working fine. When you open FactoryTalk Activation manager, it populates the activations from the server in about 1s. The wait times for opening software are pretty normal (For RSLogix 5000, "normal" isn't exactly rapid, but like I said, that's normal). For Site B, the activations take forever to refresh in Activation Manager when opened on a programming terminal. The software takes even longer to open (we're talking about 2-3 minutes). Network wise, Site B is further along than Site A. We've implemented a Stratix layer 3 switch at the top of the network and use area specific VLANs to reduce multicast noise across the network (much of the multicast noise comes from vendor equipment, not PLCs, so I can't control it). This works fine. I can remote in and use TeamViewer/VNC with acceptable performance across the network, so it's not being bogged down to unacceptable levels. However, connection to the activation server is unacceptable. I'm not sure of the culprit (yet). We are continuing network improvements, removing some older 10/100 links and installing Gigabit equipment between the Hyper-V server and the above mentioned Stratix, hopefully that might help. However, that same 10/100 link is the one I use to remote in and use Teamviewer currently, so I can't see how much improvement it will give us for activations (which really should take almost no network traffic). To get activations, I'm just adding the IP address of the Activation Server into FTActivation Manager on the programming terminals. Any ideas, people? Thanks

  23. Dear colleagues, is it possible to operate two working Modbus units on one PLC (FX3u)? For example, one as serial Master with FX3U-485ADP-MB and another TCP Server with FX3u-ENET-p502?    
  24. Dear Forum, I am working at a Gas Processing Plant which is running Emerson Delta Distributed Control System (DCS). The Control System is communicating with over 24 3rd party Packages in the field over Modbus TCP/IP using its VIM Module. We have implemented redundant communication with most of the packages so we have a primary switch and a secondary switch. We are facing a communication issue regarding an Over Head Compressor (using Rockwell Allen Bradley PLC) and Instrument Air Compressor by CAPS Australia running XE Controller (Dedicated Controller). The issue is that when the Over Head Compressor is plugged into the VIM Network (Network in which all 24 3rd Party Packages are plugged), the Instrument Air Compressor **stops communicating**. We can't even ping the compressor. At times the Instrument Air Compressor does reply but with TTL of over 30ms. When OVHD Compressor is plugged out, Instrument Air Compressor resumes communication. I have attached wire shark capture of the network with and without over head compressor. When the OVHD Compressor is plugged in, the capture shows heavy traffic being generated by its PLC (IP address 192.168.1.60). Another physical observation is that before the OVHD Compressor is plugged in the VIM Network, the NTRON Switch (Ethernet Switch) in OVHD Compressor panel shows static lights, unlike lights of a normal healthy network. When the OVHD Compressor is plugged into the VIM Network, all the lights of switches in VIM Network which were blinking previously also become static. Do the static lights mean that the network is being choked due to heavy traffic? Below are links for the Capture, IP Scheme and Architecture of Over Head Compressor. https://www.dropbox.com/sh/ar7ss8zzoo96g37/AAADguRpUDtdOnmN3xQX-Wlpa?dl=0 Please also note that OVHD Compressor is using following IPs 192.168.1.59  PLC (Internal PLC IP) 192.168.1.60  PLC (Internal PLC IP) 192.168.1.61  HMI (Internal PLC IP) 192.168.1.62  RedLion device for DCS Communication I would really appreciate if anyone would help me trouble shoot this issue.     
  25. The following is a post that was recently done. I thought that I would share... We will program a sequencer controlling seven cylinders that can be taught. The cylinders can be operator programmed from the AdvancedHMI screen. You will be able to select what cylinders to activate at each step and program in 500 steps. Our PLC will be the Do-More from Automation Direct. We will be using AdvancedHMI to communicate Modbus TCP to the Automation Direct Do-More Designer Software Simulator.  The following is the sequence of operation: Watch on YouTube: https://www.youtube.com/watch?v=In_W5SyWWBU The following is the explaination of the code: Watch on YouTube: https://www.youtube.com/watch?v=n63sXqUkjN8 To see the set by set development and the code visit our website. http://accautomation.ca/building-a-plc-program-that-you-can-be-proud-of-part-6/ Let me know what you think.
