  1. Hi, I am using syswin and i am doing an exercise on saving and moving data. My challenge is am monitoring temperature from a sensor and the range is -20'C to 100'C from the 4-20mA sensor, after conversion and testing for positive and negative the values are stored in D205. (I have done the conversion and testing for positive and negative values only assigning of bit 15 in D205 is left) The simple program has to turn on Bit 15 if the value is supposed to be negative. 1000 0000 0000 0001, a simple approach to telling us this is -1’C.  0000 0000 0000 0001, is telling us this is 1’C. Bit 15 is going to be our Sign Flag, so we have to ensure that if the temperature is positive then  Bit 15 = 0, how can we do this make Bit 15 of D205 = 0? If the temperature is negative then  Bit 15 = 1, how can we do this make Bit 15 of D205 = 1? How can i turn on this bit inside a data word? for negative i thought i could just add #8000 to the values after conversion then storing in D205 but for positive values how do i ensure that bit 15 is 0? How could you approach this? Am a bit stuck, all thoughts and ideas are much appreciated if possible you could add a snapshot from syswin or cx-programmer. I have attached the WTANK.SWP file which can be opened in syswin or cx-programmer. Look in block Main 8 Temp Buffer, Network 3 Convert to 'C WTANK.SWP
  2. Would any one help me on how to configure the Modbus plus proxy TCSEGDB23F4FA in transparent mode in order to read M340 PLC registers  to SCADA , via the Modbus plus proxy TCSEGDB23F4FA? I have set up the proxy to communicate with the M340 PLC and gave a Modbus plus node address to communicate to Modbus plus network but the Adroit SCADA device driver still not healthy in order to display the registers status on SCADA.

  3. 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?    
  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.

  6. 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. 3g3mx2 rs485 cp1l-el20dr-d

    Hi Everyone: I want to comunicate 4 inverters 3G3MX2 through RS485 (modbus) to a CP1L-EL20DR-D.   I remeber that Omron has several FB to use between some PLCs and Inverters.  I wonder if Omron has developed a specific FB to communicate these models, and if it so, where can I find them. Any of you have knowledge or can provide me these FB?   Thank you for your support.

  10. I have an application I am currently working on where I have a single AB ControlLogix PLC that needs to read data from 12+ Omron CJ2M PLCs.  The Omron PLCs don't need to read any data from the AB.   I have tried several things including the generic .eds file from Omron and the instructions in the document I found on this site:  Omron CJ2 to Rockwell ControlLogix Ethernet/IP Datalink.  The generic .eds file gave me a D6 error on the Omron side and after talking to support it does not seem like the correct path.   When I tried following the instructions for the datalink I ran into several issues.  The first issue was that after configuring my network in the Omron software upon trying to load it I got a unit mismatch message for the 1756-EN2T, the .eds file I have is for a 1765-EN2T but the card shows as a 1756-EN2T/D, so I am concerned that could cause an issue...that being said I can't find any .eds file specifically for the /D revision.  The next thing I noticed was that there doesn't seem to be be a way to link the produced data from the Omron to the AB, the Omron configuration software with the AB .eds files loaded only gave me the option to send data to the Omron which we do not need to do.  I created a generic Ethernet module in my RSLogix program for the Omron PLC and then created a consumed tag and linked that to the module but I do not see where I set up the link on the Omron side for that, so how does it know what addresses to read?? Any help would be greatly appreciated!!!! Thank you!
  11. 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.

  12. 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.
  14. 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.

  17. Hi all,    Its the first time in this forum and need help about slc05/05 processor and modbus RS485. 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  
  18. IFIX Scada communication issues

    I am new to ifix, I am having an issue, I am unable to receive any information, after attempting to fix the fact that the view was only pulling half the data I lost it all, I had a back up saved, but it didn't work on restoring communication, I was getting a cannot connect to node error, but I have fixed that, now all I am getting is question marks. essentially I believe that I have two standalone computers with the ifix software and the communicate directly with various plcs that share information across, either a ring topology or full connected. so the computer I have that is working is setup with scada and the database and MB1 with no network support, the one that is not working is set up the same, my cable connection is a usb to Ethernet and im communicating with a Comm port on the computer. I've tried different comm ports, even contacted GE, they were suppose to have someone call me back but no one has yet. Can anyone give me an idea of what I've got wrong here?
  19. 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
  20. HOSTLINK Problem

     I  am doing  a data collection from  OMRON PLC CP1L through MS excel VBA  use API function. The connection was setuped correct (I think)both in PLC and PC side. The trick things is   when PLC have USB cable connected  the data  was send to PLC and can get feedback through RS232 in normal.(I use portmon moniter the progress,and I can see the data (C-command ).But when I get the USB cable removed  ,The PLC can not get any reponse back.Dose any of you have met that  before?
