You'll need a Rockwell support contract...but first...what PLC is it?
-
You'll need Studio 5000, as long as it is Ladder only, the Mini edition will take care of you. It is about $500 for a 1 year subscription.
-
Is the PLC's RUN light on? My suspicion is you are in program mode. While online is RsLogix 500, go to Communications then RUN mode.

I jumped the gun locking this thread. Discussion of bypassing passwords is prohibited but you didn't ask to do that, you have a unprotected program that you are trying to put into your password protected PLC. When prompted, enter "65257636". This will clear the PROGRAM. Then you can download your new program.

No, you can't get help bypassing password on this forum.

Outstanding job!

Nice homework assignment. Post it when you're done and we might critique it.
I just used ChatGPT to do a similar homework assignment. Maybe it can help.

Hi Lucas. I am the author. The three basic of pieces data you're going to need is the IP address, the data address which will probably begin with a 4, and the length of data that you're transferring.

One other thought, does the 1400 have built in analog inputs? I wonder what their update rate is. Glad you like our videos!

What are the "newer" PLCs that you've successfully done this on?
-
The Micro800 has come a LONG way in the last few years. I have some videos setting up the communications but I'd guess you have that part down. It is still messaging instructions, so no Ethernet I/O but I have several of them communicating with Controllogix with no issues. Also, version 20 is out now (they skipped from 13 to 20). I have downloaded it but haven't played with it yet. I would urge you to make sure they are running version 13 so that you have the Logix theme, it makes it more like Studio 5000.

17 minutes ago, IanM8040 said:I could always just use that handy SIM IPE tool to discover them when no IP is listed too!!
That would be my preferred method :)

More likely the NAT is filtering the broadcast packets that Ethernet/IP uses for discovery. I use Virtualbox so I'm not as familiar with VMWare but it seems like there were some setting about this.
-
NATs can be tricky depending on the number network adapters and how they are configured. Hit the basics. Open the command prompt and ping the IP address. If the ping is good, look at harmony files. If the ping is bad, then look at the NAT. I always use a bridged adapter because of problems that I have had.
-
My first guess would be the Harmony files.

Contact your Rockwell Automation local distributor. They will be able to get you a 30-day trial.
-
What position is the mode switch on the PLC in? Are the sensors 2 wire or 4 wire and how do you have them wired.
-
First guess, try deleting your harmony files. They can cause unusual browsing issues such as this. Also, are you using the Ethernet/IP driver or the Ethernet devices driver? See if one or the other makes a difference.

You need to post your code so we can look at it.
-
How long are you wanting to energize for? For that single full minute? If so, why are you using the OTL? The OTE would make it true for that minute only.
-
Glad I could help.
-
Study on parameter P046, that is your command source, and P047, that is your speed reference.

Are they brand new out of the box? If so turn the potentiometer to the right and hit the green button the the keypad.

You would use Connected Components Workbench, then go File > Import Device > PVc Application
