I once had a customer that was knocking a wall down for a roller shutter door. Unfortunately there were about 30 SWA cables running across that wall and they had to jointed and re-routed.
I couldn't get my normal sparks so phoned an agency. I told them I wanted a fully qualified experienced...
GX Developer will only program Mitsubishi plc's. It will not program hmi's
Same for Gx Works 2.
The programming cable is called an SC09
They are expensive from RS but Chinese copy's on ebay are about £20 and they are usb
Gx developer is no longer up to date. Gx Works 2 covers the latest plcs.

I could tell you a hundred stories of my council house rewires.
I'm 62 now but as an apprentice my company took on all those jobs.
It was good money though, we got 30 hours each per rewire.
So 60 hours a week, finish Friday dinner. All the houses were identical so we had the right floorboards up...
Got a call from a beauty salon to ask if I repair electronic beds.
I said no but the very camp voice begged me and told me no one would repair it apart from the German makers - and they wanted a fortune.
He badgered me until I said I would come have a look.
I've never been in such a place like...
Actually, it depends on the thermistor. Some go open circuit when a certain temperature is reached and some are resistive that change resistance with temperature and need a special thermistor relay that has to be reset.
To be honest, I rarely see them connected at all (especially in fans as by...
What about the plasterers that like to fold your wires (if you don't) right into the sockets and than completely skim over them leaving you to try find them or even forget one. :)
When I first started on my own - many years ago, I had no clue what to charge. I knew what my company I had just left charged and wanted to undercut them but I had no idea where to set the bar.
Innocently, I asked a self employed plumber how he decided what to charge.
He said 'What I think I can...
When I was an apprentice sparky back in the 1970's and we were rewiring houses or first fixing new houses/flats, I was taught a marking method for T&E that seemed to be common but undocumented throughout the industry.
I'm talking specifically about lighting circuits and the loop-in system.
At...
And they swear on their mothers life they replaced them back exactly as they were.
On a lighter note: when I was an apprentice back in the 70's they introduced twin red +e 1.5mm for wiring switch wires from the light. We were wiring new flats on bonus (paid 11 hours for a first fix) We could...
When my daughter was about 15, she showed a lot of interest in the panels I was building in my workshop. She asked the right questions about the programming and was really interested in the HMI's. (operator screens if you like)
She actually taught me how to lay the screens out in a logical and...
That's right. There will be a reference to where they are, usually below the coil
Like this;
In this case K1 has a normally open contact on page 7 - under the number 5 (All pages will have a reference grid across the top and sides) ie 1-10 across and A - H down
The MA in this case will mean...
A tip for all you Sparkies is; Try specialize a bit, stand out from the crowd.
The title 'electrician' has vastly moved on since I was an Apprentice back in the early 1970's.
I'm from a time when electricians tool box's were massive and heavy. You would have in there a full set of stone...
I have interviewed many hopefuls in the automation sector. If your CV has made it through to the interview stage - that is a good start.
I could write a list of unbelievable CV's that could fill these pages.
There's an old adage that the interviewer will know if he likes you within 3 seconds of...
In reply to JulianC: The AB slc500's still exist but there are a lot newer models now
Plus, the programming language is changing.
Ladder logic is still alive and well (and the best thing for electricians to learn)
But more and more PLC's are now programmed in what would look like a computer...
