6.3.3 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 Writ e j ob (xxxx x010)
Bit 3 = 0 Re se rved (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(byte5-8)
Calculation of the value for the acceleration time
20 s x 10.000 = 200.000 = 00 03 0D 40hex
