Function Code 100 (=0X64), Read 32-Bit Parameter - BONFIGLIOLI Active cube Operation Manual

9.2.3

Function code 100 (=0x64), read 32-bit parameter

Example 1:
Reading of parameter
Fixed Frequency 2
Request: Master  frequency inverter
Field MBAP
: Transaction ID Protocol ID
Hex nn nn
Response: Frequency inverter  Master
MBAP
Field:
Transaction ID
Hex nn nn
The sent hexadecimal value is 0x000003E8 = 1000. Parameter
mal places. Thus, Fixed Frequency 2 = 10.00 Hz.
Example 2:
Reading of unknown parameter 1600 (0x0640) in dataset 2 of frequency inverter with address 1.
Request: Master  frequency inverter
MBAP
Field:
