Appendix B: Explanation of the process data
NOTE
The addresses shown in the tables in Appendix B use 0-based addressing. The Productivity Suite soft-
ware uses 1-based addressing. So, add 1 to any address in these tables when accessing these values in
Productivity Suite.
Digital Input
The order of the digital input data depends on the conguration parameter “Pin_Port_based_IO_Layout”.
This is explained in the following tables:
Port Based
Port-Based Digital Input
Byte 1 0

NOTE
The tables for Port and Pin Based are also applicable to Digital Input Qualier, Digital Output Qualier
and Digital Output.
B.1. System Status
The system state bit string provides information about the entire device.
System Status Bit String

Bit 4: At least one channel has a sensor short circuit
Bit 5: At least one channel has an actuator short circuit
Bit 6: At least one channel has an actuator warning
Bit 7: At least one analog channel has an error
Bit 8: Internal communication error
Bit 9: At least one IO-Link channel has an error (except wire break)
Bit 10: Bus/sensor supply overvoltage
Bit 11: Actuator supply overvoltage
Bit 12: At least one IO-Link channel has a wire break
Bit 13–31: Reserved, set to 0
