B-38 SLC Status File
S:15L Static Config Node Address
This byte value contains the node address of your processor
on the DH-485 or DH+ link. Each device on the DH-485 link
must have a unique address between the decimal values 0
and 31. Each device on the DH+ link must have a unique
address between the decimal values 0 and 63. To change a
processor node address, write a value between 1 and 31 for
DH-485 and between 0 and 63 for DH+ using either the Data
Monitor or node function of your programmer, then cycle
power to the processor.
The default node address of a processor is 1. The default
DH-485 node address of HHT programmer is 0. To provide
runtime protection from inadvertent data monitor alteration
of your selection, program this value using an unconditional
MVM instruction. Use the MOV instruction in place of MVM
if you also wish to protect the baud rate. The following
example show runtime protection of node address 3
