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 | not defined |
0x_8 | Process Data Invalid Bit |
Combinations are possible and are output as an addition of the values (see note below).
Higher nibble
Value | Meaning |
|---|---|
0x1_ | Watchdog detected |
0x2_ | internal Error |
0x3_ | invalid Device ID |
0x4_ | invalid Vendor ID |
0x5_ | invalid IO-Link version |
0x6_ | invalid Frame Capability |
0x7_ | invalid Cycle Time |
0x8_ | invalid PD in length |
0x9_ | invalid PD out length |
0xA_ | no Device detected |
0xB_ | error PreOP/Data storage |
Combinations are possible and are output as an addition of the values (see note below).
 | Addition of the values in case of simultaneously occurring diagnosis messages If diagnosis messages occur simultaneously, the value is output as a sum in the status byte of the relevant channel.
