Function code 16, write 32-bit parameter

Example 1:
Writing of parameter
Fixed Frequency 3
cy inverter with address 1.
The fixed frequency is to be set to 44.50 Hz. Parameter
places. Thus the value to be sent is 4450 = 0x00001162.
Request: Master  frequency inverter
MBAP
Field:
Transaction ID Protocol ID Length
Hex nn nn
Response: Frequency inverter  Master
MBAP
Field:
Transaction ID Protocol ID Length
Hex nn nn
The response contains the number of written registers
Example 2:
Writing of parameter
Fixed Frequency 3
cy inverter with address 1.
The frequency is to be set to 2000.00 Hz (non-permissible value). Parameter
has two decimal places. Thus the value to be sent is 20000 = 0x00030D40.
Request: Master  frequency inverter
MBAP
Field:
Transaction ID Protocol ID Length
Hex nn nn
Error response: Frequency inverter  Master
MBAP
Field:
Transaction ID Protocol ID Length
Hex nn nn
The sent exception condition code is the hexadecimal value 0x04 = ERROR SLAVE DEVICE.
