Consumed sizes can be in the range of 0...32. Output data for each channel always begin on a 32-bit boundary,
and is enforced by software using the data description for the channel.

Channel status:
Bit 0: 0 = Roll Up Status, an OR of bits 1 through 7
Bit 1: 0 = Connection to device, 1 = No Connection to device
Bit 2: 1 = Configuration to device in progress
Bit 3: 1 = Device configuration failed
Bit 4: 1 = IO-Link Key failure
Bit 5: 1 = DO Short Circuit
Bit 6: 1 = Process Data Invalid
Bit 7: 1 = Low Power Fault
Bit 8: 1 = IO-Link output value is forced to limit
Bit 9: 1 = No IO-Link size configured
Bit 10: 0 = Channel configured as Fallback is in the IO-Link operating state, or channel not configured for
Fallback; 1 = Channel configured as Fallback is in the DI operating state (This bit is not included in the
roll-up status).
Bits 11…15: Reserved

Produced sizes can be in the range of 0...32. Input data for each channel always begin on a 32-bit boundary, and
