Function code 06 - Write Single Register
Function
This function enables the Modbus master system to write an individual register from the
SIMOCODE pro register memory area.
A valid address from the register memory area is expected as the start address. The
selected address must be designated as writable (see the tables in Section Modbus RTU
data tables (Page 277), "Access" column).
Typical SIMOCODE parameters that can be written via Modbus RTU are the motor
protection parameters (e.g. rated motor current, trip class, as well as delay times of the
function blocks).
Slave address Function code Start address Data CRC
The cooling down period of the motor on SIMOCODE with slave address 16 is to be reset.
To this end, the new cooling down period value of 600 s is loaded into SIMOCODE.
The register address for the cooling down period is 0x419A. Cooling down period in
seconds: 600 s = 0x0258.
