Interpret Status Indicators
See the following diagram and table for information on how to interpret the
status indicators.
POINT I/O 4 Channel IO-Link Master Module – 1734-4IOL
b+1...c
Input data from Channel 2
(2)
c+1...d
Input data from Channel 3
(2)
(1) Channel status:
Bit 0: 0 = Roll-up status, an OR of bits 1...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...15: Reserved
(2) Produced sizes can be in the range of 0...32. Input data for each channel always begin on a 32-bit
boundary, and is enforced by software using the data description for the channel.
