Guess as the the display, 2711P-T7C4D8 list around $3k each...

The AB Ethernet stuff does not use the TCP/IP protocol, it uses AB Ethernet/IP

The Stratix switch will handle the protocol, correctly and is managed, all those etherent blocks are talking, and IGMP managed switch is needed.

Still have not seen what all of this stuff is talking to... If it were me, I would look for a softlogix software on a pc, but being supported by Rockwell, they would probably offer a controllogix plc or even flexlogix plc to control. Their hardware is more robust than their software. . .

Re: Field Electronics
 

Yeah, I am aware of the cost of those terminals.

I know that the Stratix handles all of that protocol.

I am pretty sure all of the inputs are talking to the Scorpion Case. I have attached a word document with pictures of the Scorpion Case. I can share with you the FMS software that I have. I think that the stratix is feeding all of the information into the server that runs FMS.

But yet this doesn't make sense because that would mean that there is AB protocol embedded into FMS. Which is possible but it just seems unlikely

Re: Field Electronics
 

There's another AB PLC inside the Scorpion Case.

Re: Field Electronics
 

There is more than one way to skin a cat. If you are looking to exactly replicate the field, renting one is the cheapest solution by far. If you want something to have & can accept close, I would go with somebody like Automation Direct. Would be a lot of work up front, but once done, the year to year changes would most likely be minor.

Re: Field Electronics
 

What function does the PLC serve?

Re: Field Electronics
 

Not very many details that haven't been shared here already. I would suggest talking to a FTA in your area. You can also volunteer at an event as the FTAA, head scorekeeper, or Field Supervisor, all of those positions have significant interaction with the field equipment.

Spending time as a volunteer around the field has definitely left me with more confidence in the FRC fields and the FTAs who run them.

Re: Field Electronics
 

It seems to me that the bulk of what is needed to build a generic (not game-specific) field is some basic networking equipment, a high-end wifi router, 8x 4 digit led displays (3 teams, plus an arena timer per alliance station), and some packet sniffing done between the DS and FMSLight to determine how the communications packets enable/disable/autonomous the robots, followed by some custom software to emulate FMS.

Re: Field Electronics
 

To everyone who said it was a secret-

I sent an email a few weeks ago to someone I had known at Rockwell Automation. And then just last week I received a forward notice that my contact had forwarded this message to the Rockwell Automation group that deals directly with FIRST.

Today I got an email from the RA FIRST department with a gif image attached with the layout and basic wiring diagram with how things are hooked together plus a model number and component name for all of the AB components used for the basic scoring system of the field

Re: Field Electronics
 

I hope you were not representing yourself as someone who had received authorization from the proper channels at FIRST to receive these documents. As for recreating a field completely from photos, instruction manuals, and a list of hardware components you still are biting off a task larger than you are thinking it is. The software that runs the multiple PLC units and firmware on the router are custom and not just regular pieces of software that is available off the web.

I would suggest you take some time and do some research into the old NASA Field that was run by Mike Wade before he passed away. Mike had the desire to have a field that he could truck around the east coast and Mid-Atlantic region of the US to host off season events and pre-ship scrimmages. After researching and working with a real FIRST field he decided it was more work to reinvent the wheel exactly as it was and came up with his own version of the field that did what he needed with a bunch of toggle switches. Albeit this was in the IFI days when dongles were able to be used with the OI's, the same could be done today.

I would suggest running with what has previously suggested, and if you really need a field for more than just some here and there practice, to use a couple switches, routers, a bunch of ethernet cables, and FMS Lite. The stress and cost you will encounter while trying to recreate a FIRST field, will be more than that to rent one if you try to have everything there that is exact as the FIRST fields have.

Re: Field Electronics
 

No, I was not representing anyone but my team when I contacted RA. I have no idea what the proper channels are to gain access to this sort of information. Plus trying to get information like that is not in the spirit of FIRST, if someone were to come and tell me "Your not supposed to have this informationThe PLC unit uses a program developed by RA engineers. The Cisco AP is being used for its exact purpose on the field, and so are the IO units. So the only piece of software I am missing yet it the PLC program.

I have looked into the Mike Wade field, it really looks interesting. But it seems that it would not be very different than our plans. And again all we are doing right now is planning. We are trying to get a feel about how hard this will be. We are trying to tackle all of the hard parts first, the biggest being the electronics to determine if its even possible to do what we want to do.

Re: Field Electronics
 

I would be interested in that. How did you get it?

We don't want to build a full field, but simulating the actual FMS would be helpful for debugging our software. Our team has had issues with the FMS not behaving the same as the Driver Station software. (In 2009, during semi-finals at Hartford we didn't move the whole match, because something weird happened with our autonomous code that was different on the actual field: http://www.thebluealliance.com/match/2009ct_sf1m2)

Would you mind sharing this information with the rest of us on this thread?

Re: Field Electronics
 

Attached is just the basic stuff that I have.

Kudos to dag0620 for posting the links to the FMS software links. He was the one who provided them to me as well.

If you are interested in all of information that I have so far it would be so much easier for me to either upload it to a file site or just email it to you, there is a lot of pdf's about radio programming and FTA monitors, audience screens, and setup for almost everything.

Re: Field Electronics
 

Any idea who to contact at FIRST to maybe get some information?
