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.

Solution
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)
  • ET 200pro EM 4 IO-Link HF (6ES7147-4JD0-0AB0 FW >= V 1.0)
  • ET 200ecoPN IO-Link Master (6ES7148-6JD00-0AB0 FW >= V1.0)
  • S7-1200 SM 1278 4 IO-Link (6ES7278-4BD32-0XB0 FW >= V2.0)
  • ET 200MP CM 8xIO-Link (6ES7547-1JF00-0AB0 FW >= V1.0) 

The download contains the library with the IO-Link blocks for STEP 7 V14 SP1 Basic and Professional (S7-300/400/1200/1500) as well as the library for STEP 7 V5.5 SP4 Hotfix 11 (S7-300/400).

The archive contains the old IO_LINK_CALL blocks for STEP 7 V5.5 and older versions for STEP 7 V12 SP1, V13, V14 including the documentation.
