4.2.5 Generation of variable data lengths in Instance 120/130
If parameter P160 is set to 0, the structure of the Instance can be freely defined via parameters P161 to P165.
The length of the output and input data does not need to be identical.

Parameter Value range Significance Explanation
P16x [0]
P162-P165 = 0
to 8
P161= 0 to 1 0 = Data length 0 byte
1 = Data length 1 byte
2 – 8 = etc. Length of status data from FI x
Data length = 0  FI does not exist
Structure:
ZST | IW1 | IW2 | IW3
P16x [1]
P162-P165 = 0
to 8
P161=0 to 1 0 = Data length 0 byte
1 = Data length 1 byte
2 – 8 = etc.
Length of control data for FI x
Data length = 0  FI does not exist
Structure:
STW | SW1 | SW2 | SW3
P16x [2] P162-P165 = 0
to 2
0 = AC-Drive profile 1 Profile used by FI x on the DeviceNet bus
1 = AC-Drive profile 2
2 = NORDAC profile
Example:
P161 = {1,1}  Inputs/Outputs of the bus module
P162 = {8,8,2}  Control/Status word and 3 Setpoint/Actual value in the NORD-AC profile for FI 1
P163 = {4,8,2}  Control/Status word and 1 setpoint and 3 actual value in the NORD-AC profile for FI 2
P164 = {4,4,0}  1 Setpoint/Actual value in AC drive profile for FI 3
P165 = {0,0,0}  FI 4 is not accessed
Input data length for the bus module: 21 Byte
Output data length for the bus module bytes: 17 Byte
