Parameter Access Method - Toshiba LONWORKS option unit Communication Function Manual

4.7.3. Parameter access method

- Example 1: Read access
A controller node reads the value of Input terminal information (address fd06). Now, Only R
terminal turns ON (value equals 0002h). The controller node sends/receives the following data.
field
mode_usi
parano_usl
paradat_usl
- Example 2: Write access
In case of controlling FL relay terminal, the controller node writes fa50 parameter (In this case, set
f132 = 38 before the access). The data value is 0001 hex. The controller node sends/receives the
following data.
field
mode_usi
parano_usl
paradat_usl
- Example 3: Illegal access
Illegal data is written to the inverter parameter f171, (Base frequency voltage, address 0171).
The upper limit value is 330.0V (200V class). In case of writing 360.0V, the unit of this parameter is
0.1V and the data value is converted to hexadecimal, so the value is 0E10 hex. The controller node
sends/receives the following data.
field
mode_usi
parano_usl
paradat_usl
