  1. Hi All. I have AB PLC Micrologix 1500 and HMI PV600. In factoryTalkView ME I have installed RSLinx Enterprise and I have setup communication setting I have created one shortcut like PLC1 linked it to PLC ML1500 which I can see in right side of setting pan. I copied these settings to Runtime target. Now while giving animation in screen e.g. colour, I am trying to browse tag but it's not showing anything in online folder. I clicked show all server, refreshed all folders and restarted RSLinks Enterprise service also but still can not find tags. I ran runtime on PC using OPC created in RSLinx Classic, Its working fine, I can browse tags. But it's not working while I download it in HMI as I can see in HMI configuration network and comm setting there is only RSLinx Enterprise is available. Please suggest me solution on this issue.
  2. 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.

  5. 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

    pranav Kotasthane posted a topic in Mitsubishi

    We are communicating FX3GE PLC with Vijeo Citect SCADA. We tried various protocols such as MelsecNET, MelsecFX2N, Melsec1, etc. If you know how please help.
  7. Hi. I'm hoping someone can give me an answer on this problem I'm having with a FX3GE PLC. I am trying to get a FX3GE plc to communicate to a drive over RS485 using a FX3G-485-BD card. In GXworks2. But am having no luck.  I have tried changing the PLC communication settings in PLC parameters between CH1 and CH2, But am unable to get any communication working on the front port. I have also tested with a FX3G-232-BD RS232 card and have the same problems. There is no activity on the SD RD led's and no data being sent. If I put the FX3G-485-BD card in a FX3G or FX3S PLC I have running the same code it works fine. So the problem I'm having is with the FX3GE PLC Please can someone tell me what the difference is with the front Communication port on the FX3G and the FX3GE. And how I can get the FX3G-485-BD card working on the FX3GE PLC. Thanks

  11. 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.  
  12. 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?

  14. 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

  17. 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?    
  18. 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.     
  19. 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.

  25. Hello there. I have connected wireless module (master) to Vijeo Citect 7.4 using RS-485 to USB converter. My slave modules are supplied power from gird/generator and the master module is supplies from a UPS.    I'm reading Modbus registers of slaves modules data via wireless master. Every time we have a power failure from grid, I get #BAD from all slave addresses. The generator kicks off within 30 sec. That is the slaves are off for 30 sec. Even after the slaves are powered on, SCADA does not poll data from it until I restart the SCADA.    My current MODBUS parameters are:   Inittype = 3, TimeOut = 3000, WatchTime = 10, Retry = 2. Could you please assist me on which parameters to change in .ini so that SCADA reads Modbus registers of slave for more than 30 sec.   I tried increasing TimeOut to 30000 but it couldn't solve the problem. I would appreciate if some one could help me out.   Thanak you in advance.
