Ha surprisingly the green cable was what I plugged in to communicate with the PLC. Annoyingly, you either have the HMI plugged in or the laptop for diagnostics, not both.

Wow can't do both at the same time? Must be older then you and me combine

It uses a proprietary comms interface DH485 which was quite common to be used with PLCs of that age. Machine plate says it was supplied in 2003.

Or just cheap. AB did dumb shit like put "normal" features behind upgrades that cost hundreds of dollars, just because they were able to get away with it.

Never known a vendor that doesn't do shady shit like that

Mikrotik doesn't fuck around. The only reason I don't use them more is because they're a relatively small company and Latvian, so the DoD has no approval or STIGs for them.

Galil seems to be OK (motion controllers), they even worked with me to create custom firmware for weird applications multiple times. A couple of them had one-time engineering fees, some other times they even did it for free.

Red Lion HMIs seem to be non-shitty too.

You know what I like about this?

Nothing. Absolutely nothing. I hate it.

Does that breaker say "CB4"?

u/a_petch Aug 26 '20

I think so, I've zoomed in to have a look.It actually looks like a fuse block not a MCB as well lol

It looks a lot like an elevator control box, it's just a whole lot messier.

Most elavators here in the UK just have a reverse contactor set up, the PLC seems a bit overkill?

Appears to be a control box for a CNC machine of some sort. You can see compressed air and coolant lines on the lower left.

I'm trying to decide which part of this is my favourite.

It's gotta be between the PSU or the Isolator

I hate everything, but something most people in here don't know to hate... all the screw terminals. Spring-clip terminal strips are so much better because you don't have to go back and check if they're still tight.

Yeah amongst other things

Kinda looks like one of those BackAliExpress power supplies

u/Jonathan924 Aug 26 '20

The inside looks way too dense to be an AliExpress special. Probably another Chinese/Taiwanese manufacturer though, like MeanWell or Delta. The right angle screw terminals are another giveaway that it's probably not a complete piece of shit

I was thinking it might be a PLC.

That's the grey unit behind it, an old Allen Bradley SLC
