•
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 of connected IO-Link devices on the master)
The data collected using this function can be used for energy and process control (EPC) of the system. En-
ergy and process control (EPC) is divided into three process-oriented modules:
•
Condition monitoring (CM): Condition monitoring to increase system availability
•
Energy monitoring (EM): Energy monitoring to optimize the vacuum system’s energy consumption
•
Predictive maintenance (PM): Predictive maintenance to increase the performance and quality of the
gripping systems
6.3.1 Device Monitoring (Determination of the Required System Parameters)
The following system parameters are used for the system monitoring functions and are made available to
the user.
The values for the individual ejectors are constantly redetermined for each suction cycle.
Current Operating Voltage (0x0042 and 0x0043)
The U
S
and U
A
operating voltages that are currently applied on the Compact terminal SCTSi are measured.

Description
Primary supply voltage
(supply voltage for sensor)
Auxiliary supply voltage
(supply voltage for actuator)
Index
0: actual value as measured by the device
1: min. value since last power-up
2: max. value since last power-up
Data type
uint16
Length
6 bytes
Access

Unit
0.1 V
EEPROM
no
In addition, the maximum and minimum U
S
and U
A
operating voltages that were measured since the last
activation are logged by the Compact terminal SCTSi.
The maximum and minimum values can be reset during operation using the appropriate system com-
mand.
