7 Application Examples
7.1 Example: Process Data with PPO Type 6
This example shows how to work with PPO type 6, which consists of control word/status word and reference/main actual
value. The PPO also has 2 additional words, which can be programmed to monitor process signals, see
Table 7.1 :

Table 7.1 Example: Process Data with PPO Type 6
The application requires monitoring of the motor torque
and digital input, so PCD 2 is set up to read the current
motor torque. PCD 3 is set up to monitor the state of an
external sensor via the process signal digital input. The
sensor is connected to digital input 18.
An external device is also controlled via control word bit
11 and the built-in relay of the frequency converter.
Reversing is permitted only when the reversing bit 15 in
the control word and the digital input 19 are set to high.
For safety reasons, the frequency converter stops the
motor if the PROFINET cable is broken, the master has a
system failure, or the PLC is in stop mode.
