13.3.13 0x0B: Read Parameter
52154
The command reads the parameter of an IO-Link device connected to the IO-Link master. The
parameter can be accessed via index and sub-index of the corresponding IO-Link object.
Parameters that are longer than 150 bytes are read with 2 acyclic commands.
1. Command: Read first segment of the parameter value
Block ID: 0x01
Parameter Data Length: 150 bytes
Parameter Data: Bytes 0...149
1. Command: Read second segment of the parameter value
Block ID: 0xFF
Parameter Data Length: Number m of the remaining bytes (m = n - 150)
Parameter Data: Bytes 150...n (n = length of the parameter)
