This input network variable is used to read and write the parameters. The parameter addresses
are determined in the application. Every parameter and actual value has been given an ID num-
ber in the application. The ID numbering of the parameter as well as the parameter ranges and
steps can be found in the application manual in question. The parameter value must be given
without decimals. Find the ID numbers of each parameter/actual value in the application man-
ual. The ID numbers are grouped as follows:
Parameter ID
1 ... 98
100
101... 899
900 ... 999
1000
1001...1999
Examples
Data format in examples is:
- learn selector <byte(3) byte(2) byte(1) byte(0)> day hour minute second millisecond
x = meaningless
Example1
Write to parameter number 102 (Max frequency "HVAC Application par. ID102") value 4500
(45Hz).
Write command to nviParSet
- LN_LEARN_CURRENT 102 <x x 11 94> x x x x
If the write command is successful then nvoParOut value is
- LN_LEARN_CURRENT 102 <0 0 11 94> 0 0 0 0
If the write command fails then nvoParOut value is
- LN_NUL 102 <0 0 11 94> 0 0 0 0
Example2
Read parameter number 112 (Nominal speed of the motor "HVAC Application par. ID112") de-
fault value 1440 (1440 rpm).
Read command to nviParSet
- LN_RECALL 112 <x x x x> x x x x
If the read command is successful then nvoParOut value is
- LN_RECALL 112 <0 0 5 A0> 0 0 0 0
If the read command fails then nvoParOut value is
- LN_ LN_NUL 112 <0 0 0 0> 0 0 0 0
