Example 1: Write parameter

Task

The acceleration time C0012 of the controller is to be changed to 20 s.

Job (byte 1/ service)

Bit 0-2 = 2

Write job

(xxxx x010)

Bit 3 = 0

Reserved

(xxxx 0010)

Bit 4-5 = 3

Data length 4 byte

(xx11 0010)

Bit 6 = X

Handshake changes frequently

(xX11 0010)

Bit 7 = 0

Only relevant with response

(0x11 0010)

SUBINDEX (byte 2)

Subindex = 0, as there is not subindex under code C0012.

INDEX (byte 3 + 4)

Index calculation:
Index = 24575 - code number
Index = 24575 - 12 = 24563 = 5FF3hex

DATA (byte 5 - 8)

Calculation of the value for the acceleration time
20 s x 10.000 = 200.000 = 00 03 0D 40hex
