Read/write data with IO-Link
Entry ID: 73565887, V3.4, 06/2022
SIMATIC ET 200eco PN, ET 200S or
ET 200AL can also be used as IO-Link
master.
Structure
The integration of the RF220R via IO-Link to the S7-1500 is performed via the
IO-Link Master ET 200SP/ CM 4xIO-Link, to which the RF220R is connected via its
IO link interface
The user blocks FB IolReadAnt and FB IolWriteAnt have been created with the
function blocks from the Library for IO-Link (LIOLink). In these blocks the following
is realized:
• the interconnection of the RFID functions
• the monitoring functions and
• the error handling.
Advantages
This application example
• already includes the above-described functions on a fully implemented basis
• can be easily customized for extensions
• includes already the configuration of the IO-Link master
• can be commissioned quickly.
