The status bytes are divided into two nibbles.

Meaning Status byte Ch. 1 - Ch. 4

Low nibble:

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 displayed as addition of the values (s. note)

Higher nibble:

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 displayed as addition of the values (s. note)

Information and diagnostic data 1:

Addition of the values in case of simultaneously occurring diagnostic messages

If messages occur simultaneously, the value is displayed as a sum in the Status byte of the relevant channel.

  • Often for example 0x03 “Port in communication OP” and 0x08 “Process Data Invalid Bit” occur simultaneously:
    0x03 + 0x08 = 0x0B (11dec)
  • The value 0x0B (11dec) is displayed in the Status byte.
