Can you give me a link to this 1.3 gbps radio product? I have some Alcatel radios with waveguides on a licensed band that only do 50 megabit that I would upgrade if there was something that could get more bits out of the same bandwidth and towers.

Do computer and software engineers stamp their drawings And reports? I’ve only seen electrical civil and mechanical drawings stamped, but that is who is involved in hydro electric.

I only work on power stations, but about 30 of 33 I have worked on are accessible by VPN. They aren’t staffed 24/7 and one crew will be responsible for several facilities in a geographic area. Bad weather causes problems and makes travel difficult or dangerous, so being able to control equipment remotely saves time, money or lost revenue, and is safer by avoiding dangerous travel.

The ones not on VPN were owned by big enough utility to have their own private fibre networks.

I am ripping out analog electronics from the 70s that nobody alive wants to support and installing PLCs with Ethernet.

The attention paid to cybersecurity goes up with the size of the facility as downtime is more expensive. Failsafes preventing damage or loss of life are seperate processors from the plc and independent often redundant systems, but still digital.

Redmine is a superior trac I think and still under development, you might like it

What is wrong with giving the profit to shareholders? That is why the shareholders bought the shares.

I have deployed close to 30 mikrotiks mostly outdoors and the hardware is robust. The software, like a lot of software, was a moving target. Features like some site to site VPN would stop working after upgrading routerOS, but once it was working and don’t change anything it was good to go.

Who is the happiest out of those groups?

I am a long term redmine user not even using source code version control features or e-mail integration. One org adopted a supported fork with an updated UI.

I haven’t found anything that can replace redmine for me, and the 16 year old UI is a bonus at this stage it is so functional without any gimmicks

Was your Volvo in China? I didn’t think any Volvos manufactured by geely were being exported, and production volume was still very low

Because the mining equipment is expensive and the duration of free electricity intervals are outweighed by expensive electricity intervals

I think you can delete just a timestamp range of a series

I will look up the query and get back to you

Vm is really straightforward to get set up, I’ve heard clickhouse admin can be more involved

Yeah I like it isn’t cloud based so my hardware at my house doesn’t depend on anything outside of my control - no updates breaking functionality etc

What specifically was not as good on the tp link omadas?

I have tp link Omada with the controller running in a container on my synology nas, works great. Got it for the fast handoff between APs, I can wander around the yard on teams calls

Do you have a link to an OEM with the 6-10k cycle spec?

State of the art moves quickly not long ago projects were budgeting for new batteries every 5 years in order to be able to meet energy guarantees

Do you have suggestions for the utilities on how to move away from a centralized grid, avoiding bankruptcy and also providing the same level of reliability as the last few decades?

The only supply side outage that comes to my mind is the Texas cold snap messing with the gas plants.

For Boolean logic ladder is still a good visual representation that can be animated to make it obvious which inputs are determining the output.

In Allen Bradley rslogix it can be entered quickly using the keyboard.

In my opinion the ladder paradigm is poor when dealing with numeric values, and function block better serves the purpose there

Fair enough, the parent comment mentioned “solar tech” and old pieces of paper and silly me didn’t realize that the power systems side works is a given and the problem is essentially hooking it up to computers and the internet to gain a modicum of convenience.

I have had great experiences with Schneider electric support for their automation platforms, and switchgear

The lead time on a transformer that size is probably a year, so a year long outage has a lot more damage than a 2 week outage

I mean, electrical engineering teaches you a lot of the math,physics,and control systems theory, and power systems that guides the design and operating characteristic of power systems devices like inverters. Sure EE doesn’t help with cybersecurity per se, but inverters and solar panels existed 20 years ago so I feel like my 20 year old electrical engineering degree is pretty darn relevant

Any transformer over about 5 MVA will probably be equipped with a low oil level switch that de-energizes it

I’m in this space, but plc io networks from Schneider and Rockwell are still “trust internally”, and some HMI or scada has to have read/write to them. At least Rockwell you could specify what variables were externally writeable whereas Schneider was essentially DMA from the network.

The management at the utility doesn’t want to be recognized for being a deficient operator that doesn’t meet standards, so they hire employees to ensure they are compliant

A fine is a black eye for a utility where people pride themselves on the reliability of the service they provide

A lot of utilities have their own fibre since they own poles/towers and need it for tele protection anyway so they can have secure a real private network between control room and significant power plants

Does it affect windows 7 and XP systems?

Nothing like asking a question on a forum and Natchwey answering with 3 pages of mathcad solving 7th order motion equations

Does your data include ascii 30 and 31?

As a co-op student I used a library to achieve fool proof encoding in csv so it escaped and quoted everything as necessary so commas,\, and quotes and any other character could be included in the data, but it was rejected since the plain text files were difficult to read and edit by hand!

Solves dependency version hell also

I like function block on Schneider platform for Process control with more analog values than Boolean. It visualizes the inputs, control loop, and output nicely.

Numeric values in ladder feels a bit kludgey
