C-More PLC's with SCADA server.

[TheDeskJockey]

I am looking for a cost effective PLC's that works with a SCADA server. These are to run pivot on the farm i work for and need the PLC's to be able to communicat with the SCADA server in there office.

What they want is to be able to turn on, turn off, run water, ext.

If you have any info on these please let me know or even point me somewhere i can find more info on it.


Thank you.

The Click is an excellent PLC. It has communications abilities. They come with 2 or 3 communication ports. Serial Modbus is also directly supported.

I have no clue what "pivot" is, so without more about what info and its format I can't offer much more insite.

Here is a wiki page giving a better idea of what i am looking to control. ( also sorry for not being more informative about what a pivot is most people i know what they are)

As long as it can connect into the SCADA system and be able to monitor for safeties and tell it what direction to run is a great start.

AH. Those. Yeah, the closest one to me is probably 100 miles away.

The Click is a pretty standard PLC with most but not all of the higher end features available to PLC users.

I'd recommend you hunt down some local technical person capable of helping and suggest you'd like to use a Click and see what they can do for you.

If you're technical and a bit clever buy a Click and it's smallest mate-up power supply, (to run it), and see if you can do it yourself.

Some investigation into how the SCADA server communicates and which protocol(s) it uses is warranted.

If a PC based SCADA server only communicates via Ethernet, then a serial comm port on a PLC presents the issue of an additional component, an ethernet/serial server.

A different PLC that talks Modbus/TCP from its Ethernet port might be cleaner than a PLC and serial server.

There's a high probability that a SCADA app can handle Modbus, but there's no guarantee until one checks it out. It might an OPC client with a single driver for brand X.

When messing with digital communications, the devil is in the details.

The C-More interfaces have remote viewing capabilities. You need the programming software to set it up, but a remote computer (PC, laptop) can view the interface via a web browser. The also have an iOS app the views the interface (iPhone, iPad). I would check with the manufacturer to ensure the models you select allow for this feature. I'm currently setting this up for a client and we are testing next week.

Mostly all SCADA servers on Ethernet network, so you need a plc that is Ethernet capable. And not an Ethernet that is not the plc's own type of Ethernet. But you need to select a scada that has a driver for the plc you are interested in at your site. Usually the scada will just read tags/data tables setup in the plc.
