7.2 Example 2: Control Word Telegram using PPO Type

This example shows how the control word telegram relates to the PLC and the frequency converter, using FC control profile.
The PLC sends the control word telegram to the frequency converter. In the example, PPO Type 3 demonstrates the full
range of modules. All the values shown are arbitrary and are provided for demonstration purposes only.
Table 7.3 indicates the bits contained within the control word, and how they are presented as process data in PPO type 3 for
this example.
