Process Data
Use the process data part of the PPO to control and
monitor the frequency converter via the PROFIBUS.
4.2.1 Process Control Data
Process control data (PCD) is the process data sent from
the PLC to the frequency converter.

Table 4.1 Process Control Data
PCD 1 contains a 16-bit control word, and each bit controls
a specific function of the frequency converter, see
chapter 4.3 Control Profile.
PCD 2 contains a 16-bit speed setpoint in percentage
format. See chapter 4.2.3 Reference Handling.
The content of PCD 3 to PCD 10 is determined by the
settings in parameter 9-15 PCD Write Configuration and
parameter 9-16 PCD Read Configuration.
4.2.2 Process Status Data
Process status data is the process data sent from the
frequency converter, and contains information about the
current state.

Table 4.2 Process Status Data
PCD 1 contains a 16-bit status word, and each bit contains
information regarding a possible state of the frequency
converter.
PCD 2 contains per default the value of the current speed
of the frequency converter in percentage format (see
chapter 4.2.3 Reference Handling). PCD 2 can be configured
to contain other process signals.
