1
Set the system variables, e.g. $A_OUT[8] in the part program or
synchronized action
2
Transmit the output signal to the signal module on
PROFIBUS DP
3
Connect the signal to the output of the module.
11.7.6 Configuration example
In the following configuration example, the following digital input/outputs are
available to the NCK:
ET200
– 24 digital inputs
– 16 digital outputs
ADI4
– 8 digital inputs
– 16 digital outputs
Note
S The I/O addresses of the modules are assigned automatically by ”HW
Config” (manual adjustment is possible).
S Each I/O address refers to an input/output byte.
