6 Component Functions
6.1 Overview of Functions
The SCTSi primarily consists of the bus module, the IO-Link class B master and between 1 and 16 ejectors.
Depending on the function, it refers to the whole terminal, the bus module or the additional modules
(IO-Link master, DI module or ejector).
Device Status of the Whole Terminal SCTSi
Many parameters and values are measured with monitoring and diagnostic functions of the compact ter-
minal SCTSi (bus module and additional modules). These values are made available via the process data
and parameter data and are used for further diagnostics.
Device Monitoring (Determination of the Required System Parameters)
•
Current terminal operating voltages
•
Ejector evacuation times
•
Ejector air consumption data
•
Ejector leakage data
•
Ejector dynamic pressure data (free-flow vacuum)
•
Ejector vacuum data (maximum or current)
Device Diagnostics:
•
Terminal status via status traffic light (device status)
•
Terminal status via extended status signals (extended device status)
•
Condition diagnostics of the bus module and ejectors (condition monitoring control unit / condition
monitoring ejector)
•
Error status of the bus module and ejectors (CU active errors / ejector errors)
•
Display of IO-Link events (IO-Link events from the IO-Link master and connected IO-Link devices on
the master)
Bus Module Functions (Control Unit)
The SCTSi bus module has the following general functions, independent of the additional modules:
Device data:
•
Device identification
•
System commands
•
Access rights
•
User-specific localization
Ejector SCPSt Functions
•
Switching points for control and component checks
•
Air saving functions
•
Blow-off functions
•
Setting for the permitted evacuation time t1
•
Setting for the permitted leakage
•
Permanent and erasable counters for the suction cycles and switching frequency of the valves
•
Manual operation
•
Ejector control (suction and release)
•
Display of the ejector status (status of the vacuum level)
