Allen Bradley CRC Errors
pturmel replied to Dean Novak's topic in Allen Bradley / Rockwell Automation
Are these CRC errors on a network port, or a backplane port, or elsewhere? It matters. I would expect a well-maintained system to run nearly error free. You may have degraded hardware, or, more likely, degraded connections (network ports, backplane card slots, et cetera). You have old hardware. If its environment hasn't been kept squeaky-clean all these years, some connector corrosion is likely. -
Allen Bradley CRC Errors
pturmel replied to Dean Novak's topic in Allen Bradley / Rockwell Automation
It is usually best to not change the time slice, but instead make the continuous task a periodic task, with a period dictated by your physical application. The vast majority of applications don't need the main task to spin as fast as possible. -
It really depends on the brand of scanner and whether they will handle a chassis-based EDS file properly. Unless you use rack optimization for the chassis' digital I/O, the EN2T would not show up in the scanners' I/O configuration at all. Just the targeted actual I/O modules. What actual PLC brands will be scanners for your case? (I suppose I should play with this in my lab..... I have an Omron NJ501 and a Keyence KV-8k that could be test dummies.)

Two Keyence Ethercat devices not working at same time
pturmel replied to taxidelt's topic in NJ Series / Sysmac Studio
From a brief look, you won't be able to fix this. The two files have the same LCID entries with different definitions. The issue is that the two models are really using the same sidecar communications adapter, but the adapter doesn't present identification based on the base unit to which it is attached. Ergo, the IDs clash. You need to file a bug report with Keyence. {Not LCIDs. Those are just language codes. It seems to be clash of Group "CB" + ModuleIdent "0x700", "0x701"... } -
You cannot. AB Logix family processors do not have support for adapter mode. They must be the scanner in any exchange. You will need to create tag sets in the CJ1W-EIP21 and manually give them connection point (assembly) numbers, then use the AB generic ethernet module.

Micrologix 1200 fault issue
pturmel replied to Brendan B's topic in Allen Bradley / Rockwell Automation
Before anything else, I would take it apart and inspect/clean all of the bus connections. It only takes a little bit of corrosion to get flaky behavior. -
Problem creating module in RSlogix 5000
pturmel replied to Mr Rabbit's topic in Allen Bradley / Rockwell Automation
Are you sure that module is compatible with older Rockwell Software? You should contact the supplier of the Add-on-Profile that placed the module in the selection list. -
(You will likely get more/better responses if you include a translation to English in your post.) But I happen to have some facility in French. To your questions: Yes, the EDS file in EtherNet/IP is similar to the GSD files used with ProfiNet. It is a standard for EtherNet/IP, so Mitsubishi EtherNet/IP products should be able to use the file. There are sometimes performance/capacity/feature limitations in some EtherNet/IP implementations, so compatibility may not be 100%.
-
Please don't double-post.
-
I can't say definitively, but I expect so, and have confirmed so for at least the EtherNet/IP protocol on these PLCs. I know that Rockwell's Logix family allows access to program tags, subject only to the family's fine-grained tag permissions. I don't know of any other brand that offers similar access.

Connect to FX5u using MXSheets over internet remote connection
pturmel replied to Crocket's topic in Mitsubishi
Wow! Ewon's pricing has skyrocketed since HMS acquired them. I think the last Cosy I bought was under $500, in 2020. (I mostly use my own cloud server VPN, based on OpenVPN.) -
From a brief review of that module's documentation (User Manual SH(NA)-080010-P(1506)MEE), you cannot send directly from the PLC to any Google email. Google, and many other email providers, do not accept email from random, unidentified devices on the internet. If using a Google "From" address, you must use an SMTP submission port (465 or 587) and OAuth credentials. Classic SMTP authentication will not be accepted (this was cut off last year). If not using a Google "From" address, the sending machine must be identified as a valid sender for the domain name (via Sender Policy Framework) and must have DKIM or DMARC encrypted signatures attesting to its validity (tamper-proofing). As shown in that manual's network diagram in §2.2, you are expected to have a proper email server in the facility with the PLC, and that server would be responsible for passing on the email with the appropriate modern security procedures. If you have such a server, then simply configure the card to point at it, and use the MSEND instruction in your ladder program to trigger a new email.

Connect to FX5u using MXSheets over internet remote connection
pturmel replied to Crocket's topic in Mitsubishi
No, a PC permanently connected is overkill. (And I don't trust Team Viewer--they've been hacked and responded lamely.) Use a true VPN. (Does your company not have an IT group?) -
Connect to FX5u using MXSheets over internet remote connection
pturmel replied to Crocket's topic in Mitsubishi
It is possible but definitely not safe, if you simply expose the target on the public internet. Learn how to set up a VPN (or buy VPN products) between your sites so that the traffic isn't exposed. -

Kiethley DAQ6510 and AB 5069 Socket Talk
pturmel replied to KennethPalesh's topic in Allen Bradley / Rockwell Automation
I'm not aware of any Rockwell products that will simply accept a bare TCP connection without a bunch of active socket operations to set up a listening socket and respond to new connections. Do you have such ladder logic in your PLC? If you don't want to write ladder to support bare TCP, you will need to learn how to use EtherNet/IP and Rockwell's data access services. -
Cooling Tower Fan & Pump Speed Calculation
pturmel replied to pop29684's topic in General Topics - The Lounge
Seems odd. Fans and centrifugal pumps have higher-order relationships between rotor speed and product velocity. If they want the latter to be linear, then use a square root or cube root function to drive the motor speed. (I can never remember which.) -
Micro 830 communication by ASCII protocol with bar code reader
pturmel replied to Pembuk's topic in Allen Bradley / Rockwell Automation
Works for me. And the file opened/expanded properly. Are you using Antivirus that doesn't permit RAR files? -
Well, that's just beautiful. Next project will be NX5.
-
I've noted that the NX family has more options for high-end horsepower, but the NJ's ability to use one or more of the CJ1W-EIP21 modules makes it much more capable for total EtherNet/IP class1 I/O and tag exchange. And the NJ can scan NX remote I/O just fine.
-
Best bang for the buck is Inductive Automation's Ignition platform. Server licensed instead of seat or page count or tag count licensed. Full disclosure: I'm an Ignition integrator, and 3rd party module developer, and very much a partisan for their product.

If you open a project export with ZIP tool, there's a bunch of XML inside. Ugly.

Studio5000 Task Monitor
pturmel replied to JacoRoselt's topic in Allen Bradley / Rockwell Automation
That usually means that, in addition to the logic in the PLC, you are also performing substantial, high-rate I/O scanning. Super fast RPI settings are not "free". -
I don't actually have any CJ-family gear processors, just NJ, and am familiar with the EIP21 because you can use it with NJ processors too (for extra capacity beyond what the built-in EtherNet/IP offers). I recommend you start with Omron manual W465.
