R Computational time of position controller and/or signal module
Dx User data exchange between DP master and DP slaves
MSG Acyclic services (e.g. DP/V1, token transfer)
RES Reserve: “active break” until the equidistant cycle has elapsed
1
Set the system variables, e.g. $A_OUT[8] in the parts 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.
10.6.6 Configuration example
In the following configuration example the following input/outputs are available
to the NC:
ET200
– 24 digital inputs
– 16 digital outputs
ADI4
– 8 digital inputs
– 16 digital outputs
Note
The I/O addresses of the modules are assigned automatically by “HW Con-
fig”. (Manual adjustment is possible.)
Each I/O address refers to an input/output byte.
