I have to admit, as someone who rarely uses the Start button (everything from keyboard) I’ve noticed little difference between 11 and 10. I’ve only left the defaults because nothing has bothered me because I just don’t use it. Thankfully th

I’ll preface this with “I think I’m good people.” Context switching is hard especially when understaffed and most certainly when doing different types of work. I’m still “executing” engineering projects, but I’m also performing inside sales

Yes, considering how fast they move I’m wondering if it’s closer to self regulated/peer quality control. Some QA/QC can make work come to a screeching halt in biopharma space (makes sense when a “batch” in the cell and gene therap

I’m not sure that I took this away from the article. Looked like they just didn’t go into detail. They mentioned storing data for keeping track of equipment health. To me that sounds like a super broad stroke that would be equivalent to his

Yes, it makes perfect sense now, but after looking at the different radius's I will not run to the window when I hear blasts.

Internal documentation (2) …good luck finding it or finding something that is relevant still. Documentation for customers (9) is usually clean, thorough and well maintained. Granted most of our customers are pharma, so heavily regulated. It

Honestly, that’s dirt cheap for a PLC. I’d say that you should have a look on Craigslist or eBay, but you probably won’t find anything much cheaper. Also, a lot of PLCs are “cheaper” because they have relatively expensive software packages

We were looking at using something like this for a hacked together solution. The customer had field equipment that could not be replaced. It communicated back to a gateway via some protocol via 900MHz radio (from what I recall not one of th

Yup, sorry. Dug into it a bit more and saw this. Thanks for the direct link though

Love the follow up comments about other file systems. I can’t believe autocorrect happened so many times without notice. One of the replies suggested it was done on purpose as to not get flagged. Is there validity there? I honestly am aski

Surprisingly enough you see this in other security driven, slow moving (static) industries. Just look at industrial controls. At the base you can say “air gap the system and it’s pretty secure.” Then you add on reliability, maintainability

TBF, hubs in general seem to fail regardless of brand. See my other comment about Dell hubs vs docking stations. A model of ‘hubs are cheap because they fail frequently’ is a poor one. Hubs should be cheap because they can’t deliver power a

USB-C hubs that I’ve used have been garbage. They’ve all crapped out after less than a year or so of use. The Dell USB-C docking stations I’ve had have been flawless. Not sure what the diff is as my Dell puck USB-C hub sucked (went through

Yes. I agree with this whole heartedly. It’s usually an issue with not understanding the other side’s perspective. Experienced/good engineers who know the space they are operating in can get a better sense of what the customer wants ev

I’m not sure I follow how you came to that conclusion. I think their point is, paraphrased, spaghetti code that meets the requirements, schedule and budget is better than pretty code that functions, but does not meet one or more of the afor

My first boss once asked me in a performance review if I was a perfectionist. I was and told him so. He then explained something that left an impression on me: the value of shipping something that works even if it’s not elegant. I think the

Interesting, I'll have to take a look at yubikey. I just installed a Tofino firewall with the Modbus Enforcer LSM between one of our DCS and accompanying SIS systems. We have never had a system communicate process data directly up the

Yea, that is correct. I typically put together the solutions for new systems, including security. I give the sales team part numbers and hours for security software and related hardware. They then add that as an option to quotes. No pri

Some time series data interfaces only work with tcp comms, which means you can’t always rely on unidirectional networks. I agree you should use them where possible though. I replied to a comment on a dupe post regarding PAT, in which analys

That's massively inconvenient, although I'm sure necessary in some cases. Some businesses actually perform analysis in 'real time' so they can adjust the process accordingly, witch requires that data be accessible. This

I think the issue there is data, even on critical infra. Modernization, reliability and the such require data analysis. There are definitely ‘strong’ ways of protecting the assets and mitigating attack vectors, but almost no way to elimin

It is mind boggling the lack of basic security principles some people have. I won't just put that on the plants and their IT/OT, or lack thereof. I've seen plenty of vendors and integrators do some cringe worthy stuff too.

I get what you're saying and that could very well be the case, but I think the 'pipeline' as a whole requires a lot of handshaking between the different stations. They would not be able to do this without their supervisory co

Totally agree, see it all the time. I even know of a few NT systems floating around out there. At least most companies are getting their IT involved to mitigate (usually they work with the vendor because they know nothing about control sys

I work in control systems OT space. A lot of distributed control systems and scada systems interface with the business layer in some fashion to provide access to time series and event data and to allow for alerts via email/mobile. So
