Network Variable Bindings
Receiving Data
A network variable input (nvi) receives data from other devices on the LonTalk network. Network
variable inputs (including their SNVTs) that are commonly used in MP503 bindings are shown in
Table 1
Table 1. Tracer MP503 network variable inputs
• The requested state of binary output 1.
• Bind to this nvi to control the binary output from another device on the
network
.
• The requested state of binary output 2.
• Bind to this nvi to control the binary output from another device on the
ne
twork.
• The requested state of binary output 3.
• Bind to this nvi to control the binary output from another device on the
ne
twork
.
• The requested state of binary output 4.
• Bind to this nvi to control the binary output from another device on the
ne
twork.
Sending Data
A network variable output (nvo) sends data to other devices on the LonTalk network. The network
variable outputs (including their SNVTs) that are commonly used in MP503 bindings are shown in
