FC 300 Profibus

Application Examples

E.g.: 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 two additional words, which can be programmed to monitor
process signals:
PCA IND
Byte no. 1 2 3 4
Type 6:
The application requires monitoring of the motor torque and digital input, so PCD 3 is set up to read the
current motor torque. PCD 4 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 FC 300 drive.
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 FC 300 will stop the motor if the PROFIBUS cable is broken, the master has a system
failure, or the PLC is in stop mode.
