Using IO-Link Function Blocks for CODESYS
For acyclic access to the Turck IO-Link master devices (in the example TBEN-S2-4IOL) as well as to
the connected IO-Link devices, Turck offers the following function blocks:
IOL_CALL (in accordance with IO-Link specification)
single acyclic accesses
IOL_WriteParamterList:
sending a parameter list for e. g. initial parameterization of IO-Link devices
The function blocks are part of the turck CODEYS library "IO-Link CALL PROFINET", V1.0.2.0 or higher.
Further information about the function blocks and their usage can be found in the operating
instructions of the Turck IO-Link master or in the function block description in CODESYS.
