Industrial Controllers

On the power side, to name a few: A-B, ABB, Cutler-Hammer, Furnas, GE, Klockner-Moeller, Siemens, Square-D, Telemecanique, Westinghouse, etc.

On the programmable control side: Some of the same names, plus Gahlil, Omron, Opto-22, etc.

(Just a mixed bag of some I have used, seen, or heard of.)

Check these.

"Industrial Controllers" is so vague as to be pointless to discuss. There are many many many kinds of "industrial controllers", the term could apply to an embedded microprocessor board, a DCS system running an entire oil refinery, a SCADA system spread out over hundreds of miles, or anything in between.

If you would like some meaningful help, describe the task you need to accomplish, a quick overview of how you are doing it now (if you are), and a general location, i.e. your country (or better yet, fill that out in the registration process so we can identify you as something other than "guest").

@Tornado : Thank you very much for the help
@MoronicBumble: This is a great link...thanks!
@JRaef: Thanks but I was only looking for some names of the manufacturers since I am very new to the field.
I do have an account with globalspec and am a regular at this forum, its just that I can't login from the place I work.

Even in guest mode, you can append identifiers such as normal username, etc.

OK, but names of manufacturers of what? PLCs? PACs? HMIs? DCS? SCADA systems? SBCs? BMS? PID Controllers? Smart Relays? etc. etc. etc.

If you narrow down the field a bit the responses can be more meaningful.

PLCs, by world wide rank of units installed from an internal report I got while I worked at Siemens for a while (2 years ago):

Siemens / TI = 55%

Allen Bradley = 21%

Omron = 7%

Mitsubishi = 6%

Schneider / Telemecanique / Modicon = 4%

Remaining 7% split among all others.

North America:

Allen Bradley = 41%

Siemens / TI = 21%

Schneider / Telemecanique / Modicon = 18%

Omron = 5%

Mitsubishi = 5%

All others are less than 5%

@JRaef: Thank you!

I am looking for a PLC for controlling a 3 revolute axes arm. What parameters should I consider for identifying a PLC. Is there a procedure/cases studies which I can follow?

If you are using servo motors for the axes, a PLC with motion control capability is a must. But if there is not a lot of other associated discrete controls, you may want to consider a dedicated motion controller. That would be especially true if you want what is called "interpolated motion", i.e. smooth coordinated movement in all 3 axes simultaneously. For example a contour milling machine.many of the same mfrs listed above also offer motion control capabilities at some level, but there are also specialized motion control companies such as Bosch / Rexroth, Galil, Emerson, Kollmogen etc. that do not sell traditional PLCs.

I went through the specifications of the motion controllers without PLCs. That is what I am looking for. Please correct me if I am wrong, to chose a controller I would need to select one which can provide sufficient power to my servomotors. But one of my motors is rated 5kW. I could only find controllers which supported a maximum of 750W motor. Do multiaxis controllers support motors with higher ratings?

Thank you very much for your help.
