Reaction in a PROFIBUS communication malfunction
Exchange of data with a PROFIBUS connection takes place in fixed cycles. The PROFIBUS con‐
nection can be monitored with the help of the cycle time:
The bus connection is considered to be interrupted if no data is exchanged between the bus mas‐
ter and the controller (as bus subscriber) after expiry of a set time period (time-out).
Time-out monitoring is activated. You may neither adjust nor deactivate time-out for
SIGMA AIR MANAGER.
After switching on the power supply, the communication malfunction can be suppressed tem‐
porarily.
Monitoring for communication malfunction can be deactivated if needed. For this purpose, the
Send
option must be selected for the data exchange.
