16 Protocol
Selects the application protocol and communication profile for the
network communication.
17 Modbus timeout
The Modbus protocol does not have an implementation for time-
out on application layer and this may be required when controlling
a drive. A supervision method has been implemented for this
purpose. If modbus timeout is set to zero, this feature is disabled.
The unit of the parameter is 100 milliseconds (e.g. ‘22’ will give a
timeout of 2.2 seconds).
If the communication fault function is activated, Modbus timeout is
the sum of communication fault time and the time defined here.
18 Output 1
19 Output 2
20 Output 3
21 Output 4
When Modbus/TCP protocol is in use, these parameters define
the output (from master to drive) data words or drive parameters
that are updated more frequently. Writing to and reading from the
Modbus/TCP register corresponding to the parameter is faster.
When PROFINET IO protocol is in use, these parameters define
the output (from master to drive) data words or drive parameters
that can be used with the vendor specific PPO’s or in addition to
the Standard telegram 1 (see chapter
Communication ). Output
words correspond to PZD's according to the table below.
0 = Modbus/TCP
1 = PROFINET IO
