Status of the IO-Link ports
There is a status byte for each IO-Link port. You can find the status bytes at the following locations:
• In the process data object "Module 2 (DeviceState Inputs)"
(example for EP6224-0002)
• In the CoE object F100

Interpretation of the status bytes
The status bytes are divided into two nibbles.
Low nibble
Value
Meaning
0x_0
Port disabled
0x_1
Port in std dig in
0x_2
Port in std dig out
0x_3
Port in communication OP
0x_4
Port in communication COMSTOP / dig in Bit (only in std. IO Mode)
0x_5
not defined
0x_6
not defined
0x_7

0x_8
Process Data Invalid Bit
Combinations are possible and are output as an addition of the values (see note below).
