  1. VFD Inventory Cycling

      Three drives of the same model when purchased in 2012.  VFD #0 went to the store room shelf in 2012 and onto the machine when VFD#2 failed in 2022. VFD #1 went to the store room shelf in 2012 and is still there.  VFD#2 was installed on the machine in 2012 and sent for refurbishment in 2022. The refurbishment included a new Control Board, New Fans and New Output Module.
  2. So I have Two VFD in my store room, both are Three Phase 480 VAC @ 25 HP drives. VFD #1 was bought in 2012 and still has it's factory seal intact. VFD #2 was received from the manufacturer as "remanufactured" in 2022 and is still factory sealed also. Now the questions? 1)     Which one would you pull to replace a drive that failed? 2)     Why did you choose the drive you did?
  3. Just thinking out loud.  55KW at 480V is 101A. using this calculator --> https://www.southwire.com/calculator-vdrop I get the attached wire requirements. The ides of a Starter Box near the pond makes sense. You might even use a higher voltage feed to the Starter Box, a step down transformer to 480 and a Fiber Run to get network controls at the starter box. Would be what I would try.
  4. Not sure if it still true with the M580s but the older "Legacy" Modicons Scanned each page of logic from top to bottom column by column, while Rockwell Scanned left to right then top to bottom. So take the following logic       A          B ----| |--------()---      B          C ----||--------() ---  If A is true and an AB Processor scans this once then both B and C will be true at the end of the scan. If A is true and a legacy Modicon Processor scans this once then B will be true, but C false.  Becasue Legacy Modicon scanned Top to Bottom then Left to Right. After the second scan both processors will have a,b and C true if A started true. Just don't expect to convert the logic and ahve it work, there may be some hiccups along the way.
  5. Last I knew the 1783-MS06T was a 6 port ethernet switch and the Schneider M580 was a PAC Controller.   I don't see how one replaces the other.   You'll need a switch of some form to connect your  BMENOC0301, your 1734-AENT and a  22-COMM-E in your  22C-D017N103 to have ethernet.
  6. Allen Bradley CRC Errors

    You make no mention of model number is this an SLC500, PLC5 or ControlLogix.   Given this equipment is 16 years I suspect that a communications module is causing your CRC Errors. CHanging the time slice gives the PLC more time to communicate and overcome the bad CRC errors.
  7. This knowledgebase article should be helpful - https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/22601 As should this video - https://www.youtube.com/watch?v=z8SyjPteeos
  8. I took a quick look at a couple of the WAGO Devices listed in your picture and they are Ethernet/IP and OPC UA devices. Both of these technologies are relatively new compared to ethernet tcp and OPC DA that was common in the RSLOGIX era. I suspect as pturmel says, your device isn't supported by the older PLC>
  9. Cannot comment on your particular Omron, but in the Rockwell world the system call {GSV} to read the Clock takes multiple scans to execute and too many of them can affect performance.  I would check yout instruction help and manuals to see how much overhead the GetTime instruciton loads the system.  Having just one I would wager won't kill anything, but do this for a dozen or more times in a scan as I've seen some "green" programmers do and all bets would be off.
  10. Fichier EDS Carte RJ71EIP91

    Google Translate told me -- Hello everybody. I am new to the forum. I work in the automotive industry and in particular on Mitsubishi PLCs. I need to carry out communication between an IP Ethernet card "RJ71EIP91 and a ZEBRA Printer. (ZT620) Zebra validated the communication with an EDS file for Rockwell.   It seems that Mitsubishi accepts EDS files too. I didn't know this concept of an EDS file. I imagine that this resembles the principle of GSD files from Siemens. Do you think that the EDS file developed for Rockwell is MITSUBISHI compatible?   Pturmel gave you the same asnwer I was going to as I was translating the post. Welcome to the forum and hopefully the more Mitsui expert users can offer specific guidance. Or from Google Translate Pturmel vous a donné la même réponse que j'allais faire pendant que je traduisais le message. Bienvenue sur le forum et j'espère que les utilisateurs experts de Mitsui pourront offrir des conseils spécifiques.  
  11. @Mr Rabbit welcome to the mrplc forums.   Could you post more information about the error you are receiving? Most ethernet devices when you open their propoerties in Studio 5000 and goto the communicastion tab will show you error text and/or an error number.
  12. 1794-AENT Setup Issue

    Rockwell has another tool?  Since when??
  13. RAU Questiions

    What is a good American doing at the Royal Agricultural University in the U.K?
  14. Thought I would post a lesson learned about the 1794-AENT. The System Integrator we had working for us had comissioned a number of 1794-AENT units calls that the latest batch won't configure. After working back and forth with RA Techconnect it finally turns out that we had been using 1794-AENT firmware 4.1 from our store room and then got into a fresh shipment of 1794-AENT Firmware 4.3's.  The BOOTP/DHCP Tool revision 3.03 we were using needed to be upgraded to 3.05 to configure the 1794-AENT.
  15. Contact Voltage?

    Many EONS ago I worked for a Japanese concern satellite plant in the US.  Was always fun when a local system integrator built a panel and 0V was tied to ground where the Japanese panels all had +24VDC tied to ground.  Every once in a while an electrician would forget which flavor of panel he was in and you'd wind up with both 0V and 24V tied to common ground.  Power Supplies don't really like that case.  LOL
