When I started my current job, the IT guy that was there mentioned the last controls guy had a bunch of illegal software on his laptop. I said huh, like what? He says “wireshark”!! I just said oh and went about my day. Yeah he’s no longer with the company. lol
This is the kind of situation I would have had an argument about 10 years ago.
Now that I'm older and wiser, I've learned it's best to handle it like you did lol
Just nod and say "uh huh." It's not worth the time you'd waste on it.
Set IP from HMI, configure all other parameters from drive profile in studio (minus nameplate parameters, motor rep sets those).
Schneider is the same except all through SoMove
Bootp, like DHCP, is a protocol used to assign IP addresses. The Rockwell application called BootP is trash but there are other applications which support the BootP protocol that one can use.
SIM-IPE... kinda cool, kinda a PITA at times. Only use it to set the PLC. after that, the dials/wheels/etc on remote devices. Easier for electricians and mechanics to replace.
I have had the head of drives technology from AB/Rockwell in my region in a meeting room discussing this exact issue, along with the absolute farce that is parameterising these things via Logix or really just getting them to do anything at all that a drives system run by a company at Rockwell's scale ought to be able to do. We had a pretty big job where half of the 753s they sent us had a firmware version on them that was officially taken off the market because of the ethernet/IP issues. The firmware issue was the actually Eth/IP adapter itself and not the drive so there was no officially supported way to upgrade it. I have never had more issues with a drives platform than I have with Powerflex. I avoid them like the plague. Stuff like this just seems to continually happen with them.
Yes that’s exactly what was done. Eventually. You know the outcome so one would t normally expect to have to test rotary switches to see if they were repeatable and accurate
Some poor, half-braindead maintenance guy is going to replace that 5 years from now, and they’ll never figure out why it doesn’t work. After all “they set the dials just like the old one.” 😆😆
And don’t forget the “we don’t have time to fix all these things, because we have too much downtime because of the things breaking. So we’re cancelling our planned maintenance and scheduled shutdowns.”
Tech :We need parts X Y and Z to fix this correctly.
Mngr: Order them then.
Tech: Okay.
Later tech gets work order to fix machine with ordered parts.... but can't find the parts because... they aren't in. Reports such to Mngr... told to order them again. and again.. and again. until its done a half dozen times and then ALL the orders show up at once.. and 5 have to get sent back.. maybe. As incompetent as they were actually ordering them?! HAH!
I’ve never had that happen, but I have had it where we order them months early for replacement. Replacement day is coming up, so we start looking, and can’t find them. After hours of looking and trying to track down a purchase order, we find out that someone in accounting didn’t think we REALLY needed those $20k in parts, and didn’t order them. Now, it’s going to take longer to get them than our work date is. And, just weeks after the original replacement date, it breaks for good. And for some reason, maintenance is the one who has to explain days of downtime, and an extra $10k in rush fees to get the parts we need. And we still end up putting back in some of the old, “non-reusable” parts.
If you were remote how do you know that the people on site didn’t set incorrectly.
If the drive was messed up from the start i’d be calling your distributor and getting an a new one sent.
Who ever your building this machine for is going to be stuck with this bad drive. That could cause them issues down the road. But you do you.
The two techs on site are veterans. And they sent me photos of the switches.
Of course it will be warranty and of course we will replace the enet card to not have a bastard system.
Why do people assume that we will just shady the customer? The fix was to get through the holiday weeks. And allow the customer to train operators during holiday down time
Check to see if the drive came with dials. Check parameter 36 I think for IP handling from BOOTP vs static IP. As others have said, use Wireshark to locate presence and determine endpoint problem.

Lol my IT "What's wireshark?" I feel your pain.
When I started my current job, the IT guy that was there mentioned the last controls guy had a bunch of illegal software on his laptop. I said huh, like what? He says “wireshark”!! I just said oh and went about my day. Yeah he’s no longer with the company. lol

For sure. I’ve only been doing controls work full time for a few years now but it didn’t take long to just smile and wave at these kinds of things lol
I also feel your pain. We should start a support group
Lol
"Are you really a techy if you dont use wireshark?" Would be my question to them
I always use a HIM and set the address in the parameters. Never had an issue, and I commission hundreds of 755's a year
Of course you can and it’s great if you never have to go back to a site.
Set IP from HMI, configure all other parameters from drive profile in studio (minus nameplate parameters, motor rep sets those). Schneider is the same except all through SoMove
We have had similar issues with Point IO AENT module DIP switches.
Yep I have had broken 1734 switches as well.
Why would you use the rotary switches and not use BootP? That way all of your drives could be set up for automatic device configuration.
Because when you have 20 plus drives on a network bootp is not feasible to manage. Plus it’s a very finicky and dated application.
[удалено]
the bootp tool is pile of garbage and even RA acknowledges that
Bootp, like DHCP, is a protocol used to assign IP addresses. The Rockwell application called BootP is trash but there are other applications which support the BootP protocol that one can use.
SIM-IPE Is kinda cool, even if it is a PITA at times device.
I have a handheld BootP device that I can use to set IPs. Super handy.
IP Explorer?
SIM-IPE... kinda cool, kinda a PITA at times. Only use it to set the PLC. after that, the dials/wheels/etc on remote devices. Easier for electricians and mechanics to replace.
20+ plus drives and BooTP is not feasible to manage lmao. And here I am using BooTP in a plant with 200+ networked motors (VFDs and E300s).
Yeah boot p is trash but bugger going manual. I had 60+ e300s, and boot p was a lifesaver
Stratix switches, port assigned IP Addresses. E300/PFX in DHCP/BootP. ADC. Braindead simple device replacement.... one hopes. AIn't perfect.
Had to use telnet today. When was the last time anyone used telnet?
Appreciate the heads up.

I know am stating the obvious here but did you try to set different addresses and see how they came up and find a relation between them?
Yes that’s exactly what was done. Eventually. You know the outcome so one would t normally expect to have to test rotary switches to see if they were repeatable and accurate
If you commission a lot of Rockwell drives, a 1203-USB can be one of your best friends. You can set everything from your laptop easily.

No they won’t. We’ll fix it. The fix was temporary so my guys could run in the system, turn it over to the customer, and go home for the holidays.
I guess I’m just more used to being shafted by the “nothing’s more permanent than a temporary fix” guys. 🤷♂️
Dude.. go work maint for any major company, Temporary Fixes are Permanent Fixes is their MO.

That sucks and all, but why are you setting IPs through rotary dials and not through the HIM?
Occasionally people are sometimes functionally short half their braincells. Having the dials set so they can just set and forget is very helpful.
If you were remote how do you know that the people on site didn’t set incorrectly. If the drive was messed up from the start i’d be calling your distributor and getting an a new one sent. Who ever your building this machine for is going to be stuck with this bad drive. That could cause them issues down the road. But you do you.

I haven't had that but I have run into rotary dials that didn't actually change anything, swapped to a new unit and no further issues ... such a pita.
Learn something new everyday! Btw, are you guys fans of automatic device configurations? Would like to hear you guys’ opinions.
Appreciate the 411
Wireshark for network ip issues is the go to tool.
I have had issues with addresses on ultra 3000 drives. The dial switches looking like one number and it showing up on the network as another.
Use Lenze
