  2. 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?    
  3. It's another BOOTP post! I know you're all as excited as I am, so lets get started. But seriously, I'm trying to disable BOOTP on the built in Ethernet ports, not on an Ethernet module. I specifically say disable because BOOTP successfully assigns the IP address to my Compact Logix, however I still need to disable BOOTP to make it a static IP address rather than a dynamic IP address. I'm going to list everything that I have tried, so that anyone with the same issue can have an all-in-one-place reference. (Because there's a number of forum posts and other information for this topic on the internet, with many different suggestions) If I see different ideas/suggestions in other places, I can edit them into this post. Things I have tried: (and you should try if you have this issue) Disabling all firewalls, (For me: Windows/Avast) Disabling all other network adaptors. (Wifi especially, but any and all adaptors you are not using for the setup) Using a different laptop/operating system: (My current laptop runs windows 8.1 and uses a Linksys usb to Ethernet device to talk to the PLC, I tried a laptop running windows 7 which communicated using a built in Ethernet port) Lastly: Try to use all available methods to disable it. For me, that would be: BOOTP standalone server, RSLinx, (Trying to use both USB and Ethernet connections) and finally RSLogix. (Actually, only Ethernet modules have a "disable BOOTP" checkbox built into RSLogix, so that is not an option for me.) [If you have an Ethernet module, go to port configuration in RSLogix and uncheck the "enable BOOTP" checkbox] Anyway, RSLinx Classic (version 3.71) and BOOTP Standalone server (version 2.32) are each coming back with an error when I try to disable BOOTP. I'll attach a .jpg of some screenshots, and some Wireshark save files to show what I mean. In the RSLinx Wireshark file, it shows a "privilege violation" packet being sent from the PLC to the laptop towards the end of the exchange, but I'm not sure what privileges the laptop needs/doesn't have. For the wireshark files: I cleared everything happening before I try to send the command, so that there isn't a ton to search through. As far as timing of the wireshark files go: I start recording traffic, send the disable command (by clicking the disable BOOTP/DHCP button on BOOTP server or "apply" on RSLinx) then I stop recording traffic once I get the error message. So, the captured packets should be just the attempt to disable BOOTP and that's about it. I am sorry that I the pictures are strung together using paint, but I don't have photoshop on my work computer so it's the best I have. Any suggestions/help would be appreciated! (Regardless of whether they are suggestions for me, or suggestions that I may have missed intended for anyone with this problem.) Thank you for your time. Edit: I had the attached pictures open in paint/photo viewer, sorry that they look bad in the forum picture viewer. BOOTP_wireshark.pcapng rs_linx_USB_wireshark.pcapng rs_linx_wireshark.pcapng
  4. 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.     
  5. 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.

  7. Deploying An AdvancedHMI Project Here is our latest post on deploying an AdvancedHMI project on the industrial floor. Here are a few thing we cover: Hardware - Fanless Computer - Monitor - USP - uninterrruptable power supply Software - Turn Off windows update - Security - Set permissions - Limit internet use - AdvancedHMI - remove ControlBox, Miximize Screen Size, Topmost property Here is part of the post... Deploying an AdvancedHMI project on the industrial floor sounds like an easy task, but there are a few things that you should consider. The HMI (Human Machine Interface) user interface will run on a computer. The industrial environment is one in which temperature, dust, electrical noise, etc. are always present. This can also be combined with workers wanting to play with the new computer. We will look briefly at the hardware and software items that will make your install more reliable and user friendly in the field. Read the rest of the post... Let me know what you think.

  8. 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.

    This is a short bit of sample code using Socket Service function blocks to read and write data from / to a V680S RFID tag using the Modbus TCP (-ETN) version of the V680S.
  10. Here is a recent post that I would like to share. Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in your application with different parameters. The information collected in the database can then be distributed or analyzed in the future. Visual Basic 2015 will be used with the EasyModbusTCP client/server library for .net. We will communicate to an Automation Direct – Do-More PLC. Using the free simulation software of the PLC Designer Software, we will retrieve three values of the Modbus Holding Registers using Modbus TCP. Once we have this information out of the programmable logic controller it will be placed in a Microsoft Access (2010) Database. This will be done by using a SQL command to insert the data. Read the rest of the post... Let me know what you think, Thank you Garry http://accautomation.ca/

We need to link one slc05/05 with 5 power analysers and 3 vfd all with rs485 modbus rtu ports, as i now the slc05/05 have RS232 that suports Modbus, can we put an converter RS232 to RS485 and put slc05/05 to read write the power analyser's and vfd's. There are any sample / step by step tuturial with modbus and slc05/05 ?   Best regards, Jorge Cruz  
  14. CP1E MODBUS Maximum Slave

    Hello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance

  25. Hello, I am new to the connected components workbench software. I am working with an AB panelview component Hmi and would like to create numeric buttons to load integers into user variables in a schnieder LMD servo motor. The motor uses Modbus TCP to communicate. It appears that if I click on the numeric buttons properties there is a "Write Tag" of which you can use some default tags or create a new one. I am assuming that I need to create a new one with the motor's addressing but I'm not quite sure how to accomplish this. Any help would be much appreciated!!! Thanks, Steve
