Issue
How many LonWorks Units can you have on Vista system?
Environment
- TAC Vista
- LNS network
- LON devices
Cause
Understanding the LON device maximum limit prior to designing a new system can avoid problems later on.
Resolution
The official limit is 1000 LWUs on a TAC Vista system.
But there are several plants that are using many more. It depends on the amount of communication there is between TAC Vista and the LWUs
TAC Vista can support 3200 (50*64) LWUs on each LonWorks network. A TAC Vista system can contain 65535 objects (sum of Logical and Physical).
