Acyclic Read and Write with the IO-Link Library

  • Entry
  • Associated product(s)
The function blocks IO_LINK_MASTER and IO_LINK_DEVICE represent the implementation of the communication (PROFIBUS DP or PROFINET IO) from and to IO-Link devices and master modules standardized for IO-Link technology.

The following library contains function blocks for processing the device parameters for IO-Link communication modules of SIMATIC S7 and the data records of the connected IO-Link devices.

IO-Link block Functionality
IO-LINK_MASTER_4Using this function block helps you save and restore the device parameters and settings of an IO-Link communication module/ IO-Link master with 4 ports via the S7 program.
IO-LINK_MASTER_8Using this function block helps you save and restore the device parameters and settings of an IO-Link communication module/ IO-Link master with 8 ports via the S7 program.
IO_LINK_DEVICEUsing this function block helps you write device parameters to an IO-Link device acyclically via the S7 program, or read parameters, measured values, and diagnostic data from an IO-Link device

The IO_LINK_MASTER block works with the following SIMATIC S7 communication modules 

  • ET 200SP CM 4xIO-Link (6ES7137-6BD00-0BA0 FW >= V2.2)
  • ET 200AL CM 4xIO-Link (6ES7147-5JD00-0BA0 FW >= V1.1)
