6.3 Acyclic data exchange with the IO-Link library

Result
You have updated your ET 200eco PN device online with a new firmware version.
Starting with version V6.0.0, if the ET 200eco PN I/O device was reset to the factory settings
before the firmware update, the port parameter assignments are transmitted and activated
again as a result of the neighborhood detection after the first connection is established
between the controller and the ET 200eco PN I/O device. In previous versions, the device
name had to be reassigned by selecting PLC > Edit Ethernet Nodes ... .
NOTE
You can also update the firmware using HW Config. You can find additional information in
the STEP 7 online help.
6.3 Acyclic data exchange with the IO-Link library
Function blocks "LIOLink_Master" and "LIOLink_Device"
For acyclic data exchange, you can use the function blocks "LIOLink_Master" and
"LIOLink_Device" for controllers of the S7‑300, S7-400, S7-1200 and S7‑1500 product lines.
The function blocks support the following tasks:
• Parameterization of an IO-Link device during operation
• Executing IO-Link port functions
• Diagnostics of IO-Link devices
• Backing up/restoring IO‑Link device parameters
NOTE
Function blocks "LIOLink_Master" and "LIOLink_Device"
The function blocks "LIOLink_Master" and "LIOLink_Device" replace the functions of the previ­
ously available block "IOL_CALL".
The "LIOLink_Master" function block is used for all functions and accesses to the IO-Link mas­
ter, and the "LIOLink_Device" function block is used for all accesses to the IO-Link devices.
Ensure for the IO-Link master 6ES7148-6JD00-0AB0 that the "LIOLink_Device" function block
is only used for the configured submodules.
