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 control word telegram is sent from the PLC to the frequency converter. PPO Type 3 is used in the example to
demonstrate 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.
