Activation not found when on isolated network

Posted By jjstraight Sep 18, 2023 01:32:00 PM
Found In Egroup: Installation & Activation \ view thread
When I start Studio 5000 while on a network with no Internet connection, it doesn't find my activation. I don't feel like it's always done that. Is there a setting that I need to change? If I have the license installed locally, why does it need to access the Internet? It doesn't seem to care if I have ...

RE: 5% of a moving 24 hour window

A simple way to do it is to do a bit shift on a DINT[2700] once per second. If the threshold is exceeded, latch a bit that gets shifted in. Clear the latched bit when you shift. If you shift in a one, add one to a count that tell how many ones are in the array. If a one gets shifted out, subtract one ...

RE: Command vs. actual position glitch on virtual axis

Posted By jjstraight May 26, 2022 08:47:00 AM
Found In Egroup: Drives, Motion Control & Low Voltage Products \ view thread
Since I'm only referring to a virtual axis, I am expecting command and actual positions to be exactly equal. I've been doing this way for many years and this is the first version that I've ever seen this glitch. I'm less concerned that the actual and command don't match, as I am that the command position ...

Vincent, That's the next step. I wanted to post it here first to see if anyone has already run into it. Using actual position for my MAOC has resolved it for now. Here's a screenshot of the trend. Sorry if CommandPosition is hard to read. This happens right as an MAJ is initiated. The bit from the ...

Command vs. actual position glitch on virtual axis

I was wondering if anyone else had run into an issue where .CommandPosition doesn't equal .ActualPosition on a virtual axis. The Rockwell documentation states that a virtual axis doesn't have an actual position, so .ActualPosition returns the same value as .CommandPosition. In my case, I use the command ...

As TJ mentioned, a little more information would help. If you're controlling the 525 over Ethernet, you may only need to change the module definition in the I/O configuration. Newer Logix versions: Bring up the properties in the I/O Configuration, click the "Device Definition" button in the ...

RE: How to setting Axis scaling of ball screw vertical load ?

Thanks for the reply. It makes perfect sense. I've only used SEW's gearmotors for small conveyors and such, where exact ratio didn't matter. I haven't used their servo gearboxes. I saw on their website that they make a point of saying their servo gearboxes are integer ratios. I've just never seen it ...

TJ, Out of curiosity, do you have an example of a gearbox with an approximate ratio? I've never run into that in all my years. Thanks, Jeremy

RE: Msg in AOI (Structured text)

If I'm understanding you correctly, Source Element in the configuration dialog box is equivalent to RemoteElement in the MESSAGE tag.

I'm not sure what you're asking. Your MESSAGE-type tag is passed to the structured text version of your AOI as an InOut, just like the ladder version.

I've never seen that be a legitimate glitch. Normally, I would think the timer tag was being used elsewhere. If a cross-reference doesn't show anything unexpected, try a new tag entirely in case it's being written to externally. ##HL38

Yes. Either VAR_MSG -> msg_var or VAR_MSG[0] -> msg_var[0] will work. If you don't specify the element number, it will imply that zero is the first element. ##HL38

If you're only reading from the L43, you would only need to put the L43 in the L33's I/O configuration. It's not necessary for a MSG instruction, but it can be easier in a lot of cases versus figuring out the path manually. As for your 6 INTs, I think the easiest way is to add code to the L43 (six MOVs) ...

I think you can only access the I/O in "listen only" through the network, not the L43's backplane. I think the easiest solution is to NAT the L33 onto the 10.231.154.xxx network and MSG the AENTR's I/O tag from the L43. ##HL38

You can't connect the L43's local network to the L33's local network if there are duplicate addresses. The options I see are: Eliminate the address conflict Connect your L33 to the L43's other Ethernet module via a NAT device. ##HL38

Blake, It looks like it might be a Windows display scaling issue. I've run into it in the past with the Windows 7 scaling where Windows scales certain objects not realizing that the dialog box is not auto-sizing to fit everything. I can't seem to duplicate it on Windows 10. What OS are you running? ...

Just to add to Squiggley's post. You'll need three static IP addresses on the public side; one for the 9300-ENA, one for the PLC, and one for the HMI. The PLC and HMI need to be added as rules in the 1:1 NAT configuration tab. ##HL38

It wasn't necessary to have a gateway address in the PLC's original configuration. The HMI's not acting as a gateway to anything. I would do the following: Change either the 9300-ENA's private address or the HMI's address. Obviously they can't be the same. Make the gateway address of ...

I ran a quick test trending CurrentFeedback. It seems to read, on average, slightly higher than TorqueReference. It also appear to be a noisier looking signal. Even with the drive in safe-torque-off, CurrentFeedback was showing spikes as high as 15%. ##HL38
