4.2  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.
