What, you are saying you don't like ALC because for example they use 156K baud ARCnet for their BACnet MSTP backbone. Who comes up with this stuff !!!
lw You have an ALC portal that is custom made and programmed. Next to impossible to get any information about it without forking out some cash to ALC.
Originally posted by sysint lwarren- call MCS. Looks like a Modbus protocol device.
Rather than use that stupid ALC portal (very expensive) get some information from them to use a Modus/LON gateway.
Initially I'd say Fieldserver, although Amigo has a link on a recent LON post (by Cardinal?) to a slick little European gate.
Then throw that ALC piece of junk (for LON) in the trash can.
We did not supply the portals, probably going to be hard to sell something else altogether unless we just cannot make these work. According to MCS they have sent out plenty of the portals for lon integration to their MCS-8 controllers and ther has been no problem.
I probably don't have something configured right, or I still think there may be an issue with the xif file.
I would'nt mind the challenge of making this work if time was not so critical.
Thanks for all the responses everyone, I will keep yall informed.
Carrier's LON interface - They actually have some flexibility.
You configure/MAP through CCN. Maybe have the Carrier rep send you an XIF and you tell them all the extra I/O points you would like to have. For instance, you may want all the transducer data if available. Really, any data their stupid overpriced little touchpanel has you should be able to get.
We had a problem with the beta-cards needing to be powered slightly after the onboard CCN controller. They may have solved that problem.
Well after months and months of trying to resolve this problem, it has finally been figured out. Honeywell came out to the jobsite and tried to commission this hunk of junk with Care, Lonmaker, and Tridium. The device would not commission. Then they noticed that the Subnet and Node Id for the device would not change from 0-0. The only way they could get it to change was through Honeywells Excelon software. But, if you lost power to the portal the the stupid thing would revert back to 0-0. So whenever LNS would try to set the Subnet and Node for these devices they would not take it.
So now we have to remove all of these portals, ship them back to automated logic so they can change a parameter in the portal to accept the Subnet and Node ID's.
