(e.g. ET 200S with CPU or S7-1200),
see Catalog ST 70 "Products for Totally Integrated Automation"
•
IO-Link master (e.g. 4SI or 4SI IO-Link electronic module for
SIMATIC ET200S or SM 1278 for S7-1200) see Catalog ST 70
"Products for Totally Integrated Automation"
Each monitoring relay requires an IO-Link channel.
