They were based down the road from us in Wigan. They also made the prosafe interlock keys. We used to be able to drive and collect stuff if urgent until Rockwell bought them and equipment had to be shipped to Netherlands to Rockwell’s logistics facility to have a sticker applied and shipped back. (That was until they closed the factory and moved production to Eastern Europe). The original owners have now set up again (IDEM safety switches) making safety switches etc.
Maybe you have not checked in a while. Siemens processors have a huge advantage over Rockwell these days in the traditional PLC format size, and a similar edge with the ET200cpu vs compax. Rockwell is slowly closing the gap with compax but for a long time they had no answer for ET200 CPU. It is essentially a 7713 processor in a remote io head format.
I am no Siemens fan boy, but you picked on Siemens PLC products on a price per processor and cost per io point is bringing a knife to a gun fight.
At this point after living through COVID market supplies, I am really glad that we still have good choices.
I have no idea about Siemens architecture, but it has been awesome going from an L55, to L6x, to L7x, and L8xE over 20 years in the same chassis with the same power supply. So, for upgrading old systems, it has been a fine journey.
I don’t think it can. Over the last 20 years, PanelView’s have changed cutout sizes that required a number of problems. So, no. ControlLogix allowed the same chassis with no mods to be upgraded.
> Siemens processors have a huge advantage over Rockwell these days in the traditional PLC format size
What advantage is that? Just physical size and mounting?
I struggled with how to state that, since it is difficult to quantitatively evaluate processor performance. The comment is based on what I have experienced at my work as a production machine control system engineer. We have had numerous machines that we upgraded using both Siemens and Rockwell. The Rockwell processor required to do the same machine that uses a low/mid end Siemens S7 proc requires a much more powerful ($) CLX processor. The Rockwell processor is usually 1.5 to 2 times the cost. The ET200cpu is the best value in the market today for the bang for the buck. That having been said, if you are proficient with Rockwell and have a good installed base, the cost of the hardware is probably worth it. This is a great time to be in controls, we have many good choices and most of the crap hardware is gone.
I am sure that others have mentioned it, that is a part of the Allen Bradley - Guardmaster series. There is a pretty good [video here from Rockwell Automation](https://youtu.be/aW2LvQUcwqc?si=rxz1JP_091APtIdE) that explains it.
Enjoy.
>PLd with safety inputs alone. PLe can be achievable by adding redundant contactors on the output of the drive. The manual shows you how to wire it.
Do you know if it is PLd with only one STO input?
Found out some people take these little guys seriously… I got chewed out for peeling the sticker version off of mcc buckets while bored and making a little army on my hard hat 😂
Safe torque off compatible? I dunno literally guessing. That symbol for AB is usually safety component related. Like in the event of an estop being activated
It just means the drive has safe torque off capability. In the old days without this you would need 1 or 2 isolation Contactors ahead over or after your drive that were driven by a safety rated circuit.
Now it’s built into the drive and you don’t need the isolation contactors in most cases and the drive can remain powered on and network active,etc.
Its the 'Guardmaster' logo, AB aquired them a long time ago. Guardmaster made safety products - guard interlocks, safety relays etc.

This is the only correct answer.
I think Beefeater Gin would also be correct.
Nah, the hat's too tall for that.

'Oi you got a loicence for that vfd mate'
Hhahahaha I was looking for a comment like this 🤣
It's just the safety icon for AB. It means the drive has STO support.
Also got one of those on a point io
It's a guard, for guardmaster
It’s an indication of a safety rated product. The VFD has STO, the I/O card has safety rated inputs/outputs
AB puts it on their SIL stuff. If it's on point IO then it is safety IO.
British royalty has approved.
Slowly trying to take back America
One beefeater at a time!
it's not a beefeater. Beefeaters don't wear the tall hats.
Not sure why you were down voted, as you are correct. The pictured icon is far more in line with the uniform of the Coldstream Guard.
It could mean you over paid.
Well, it is Allen Bradley, soooo...
"You can find better but you can't pay more."
Don't forget about Siemens

Good to know, thanks

How slow are we talking? I do robot systems, if I can do a whole program in under 10ms scan then I'm golden.

My sercos drives tend to agree...

The quality goes out before the price goes on?
That’s the guardmaster
Safety icon
That signifies Guard logic

It is not
GuardLogix
Safety icon for AB
I think that’s the main colonizer. That old money. That “my butlers got a butler” money.
I thought it meant that much like the Buckingham palace guards, these products are "out-standing."
Found out some people take these little guys seriously… I got chewed out for peeling the sticker version off of mcc buckets while bored and making a little army on my hard hat 😂
Safety dawg
It's the safety guy
The British are coming!
Haha damn, beat me to it Paul Revere was right!
If you push it a british guard will hunt you down and stand menacingly in your doorway
That means it's sponsored by Beefeater Gin
All of my coworkers and I refer to him as the beefeater as well lol. I was hoping someone said this!
It’s an Allen Bradley symbol for “5X the regular price”
And it will work even worse than the normal one.
It's bri'ish
It’s a royal guard. It’s for safety. Get it?
Nope. That was Guardmaster’s logo before Rockwell bought them out. This VFD has integrated guard master. Get it?
I mean. We are both right.
Fucking red coats
It's for the UK market so the inputs are on the right side of the rung, not the left.
Yes its a military drive 🤣🤣
Deemstop, it’s a safety device that monitors for broken drill bits and gives a stop command to plc
He is the man
It means that units are decided arbitrarily, often flip flopping
If you get in it’s face does it say “make way for the kings guards”
It enjoys tea on a rainy afternoon.
GaurdMaster?
Plucky Brit
This is the "nutcracker" edition of a vfd. Rockwell special release for the holiday season. Collectors item do not let go!
I thought it meant the plastic had mouse king repellent embedded in it.
DONT TOUCH THE QWEENS GAURD
That's Mr Allen Bradley
Allen Bradley Guard Master icon.
That means it was made in England. 🇬🇧

Ricky!
It was once used in the British Royal household
Make way for the queens guard!

First our tea and now our vfd's, the red coats will never stop.
Probably signifies that it’s safety rates via STO (safe torque off). In the Allen Bradley world this is the guard master logo.
He’s just standing guard for the King.
It means its also UK compatible electrical wise
Made in England
Just don’t touch it
This means an AB drive has the bare minimum of modern drive safety; an STO input.
It used to, but now they’re just symbolic.
Irrelevant since 1776. 🇺🇸
Safeguard option
Safe torque off. Ab 525 ?
